What is an Elastomeric Membrane for Flat Roofs?

Flat roofs are a common feature of modern commercial buildings, as they are both practical and visually attractive. Over time, roofing technology has evolved from traditional asphalt and gravel methods to more advanced and durable solutions. Elastomeric membrane stands out among these innovations as a leading choice for protecting flat roofs.

Our Montreal roofers present you this complete guide to elastomeric membrane roofing.

Elastomeric membrane flat roof covering

Elastomeric membrane is your best option for low-slope or flat roofs. It’s made from polymer modified bitumen (PMB), which gives it flexibility and strength, and is often reinforced with a fiberglass or polyester mat to make it even more durable.

This modern roofing technology was developed through ongoing efforts by the construction industry to develop materials that are both strong and resistant to the elements. It offers a superior alternative to traditional roofing materials.

Elastomeric membrane layers

Elastomeric roofing is composed of two layers. These are heat-welded together during installation to form a single, continuous membrane. Once fused, the membrane acts as a highly effective waterproof barrier that allows the roof to breathe without any risk of moisture build-up.

Base coat

The first or base layer is made of elastomer modified bitumen (EMB). This layer serves as the first barrier against water and weather. It is usually reinforced with a fiberglass or polyester mat to increase its strength and durability. The base coat is applied directly to the roof substrate to create a strong, long-lasting bond.

Finishing coat

The second layer, or finishing coat, is also made of modified bitumen. However, this topcoat is covered with colored granules or another special protective coating. The second layer not only protects the flat roof membrane against UV damage and climatic variations, but also gives the roof its final sleek appearance. Granules can vary in color, making it possible to personalize the roof’s appearance to some degree.

Advantages of elastomeric membrane

Elastomeric roofing offers many significant advantages! Our certified roofers outline the most notable benefits.

Outstanding durability

Elastomeric membrane is widely recognized for being exceptionally durable and long-lasting, with a life expectancy of up to 35 years. This high performance results from its unique composition, which gives it superior resistance to the challenges posed by Quebec’s extreme weather conditions.

Easy to install

In addition to being robust, elastomeric membrane is easy to install and requires very little maintenance. These are major advantages in terms of both initial costs and long-term upkeep. Thanks to hot-application techniques and self-adhesive products, elastomeric membrane can be laid quickly and safely, using minimal labor with a low level of risk.

Multiple customization options

Elastomeric membranes give a sleek, modern appearance to buildings. They are available in a variety of colors, making it possible to customize a roof to match the architectural style of the building. This roofing material is a versatile solution that can be tailored to the specific needs of each project.

How to install an elastomeric membrane

Installing an elastomeric membrane on a roof is a technical process. For safe, effective installation, it’s important to prepare carefully and rely on the expertise of qualified professionals.

1. Preparing the roof

Before installation, the roof must be cleaned of any debris, dust or materials that could prevent the membrane from sticking correctly. Any surface irregularities must be smoothed out so the membrane can be applied evenly.

2. Applying the undercoat

The first layer, or undercoat, ensures that the roof always remains watertight. This layer can be mechanically fastened to the roof, or glued, depending on the manufacturer’s specifications and the condition of the roof.

3. Installing the elastomeric membrane

Next, it’s time to install the elastomeric membrane. For traditional installations, roofers use a blowtorch to heat the membrane so that it fuses with the underlay. It’s important to avoid creating any air bubbles or creases that could compromise the seal.

4. Cold application technique

Cold application is becoming increasingly popular as an alternative to using a blowtorch. This method involves using self-adhesive membranes which do not need to be heated, so pose no risk of fire. This technique is a safe and easy installation option.

5. Finishing

Once the elastomeric membrane has been installed, finishing touches can be applied to the edges of the roof, and around drains and other roof elements, to ensure maximum protection against water infiltration.

6. Inspection and cleaning

Installation ends with a detailed inspection of the membrane to check for defects and make sure all areas of the roof are covered properly. Roofers will also do a final site clean-up.

Elastomeric membrane maintenance

Mantaining an elastomeric membrane is relatively simple and less demanding than for other types of roofing. Still, there are a few things you can do to make your roofing last longer and perform better.

  • Regular inspections: We recommend inspecting the roof at least twice a year, usually in spring and autumn, to detect any problems like cracks, bubbles and tears in the membrane, or issues at joints and edges.
  • Cleaning: Clean the surface of the elastomeric membrane carefully, using soft brooms or low-pressure washers to avoid causing damage. It is important to remove debris, leaves and other items that may accumulate on the roof and clog drainage systems.
  • Minor repairs: If you detect minor damage, such as cuts or punctures, we recommend that you contact a roofing professional as soon as possible.
  • Maintenance of drainage systems: Gutters and drains should be checked and cleaned regularly to ensure proper water drainage. Water accumulation on the roof can lead to long-term damage.
  • Monitoring after major weather events: Inspect your roof for damage following heavy storms or significant snowfall.

What is EPDM Roofing?

EPDM roofing membrane is an innovative and durable roof covering that is the solution of choice for flat and low-slope roofs. This type of roofing is resistant to extreme weather conditions and lasts a long time, making it a reliable alternative to traditional roofing methods.

In this article, our Montreal roofers explain what makes EPDM roofing unique. Keep reading to learn about the advantages it offers, how to install it and the type of maintenance that will maximize its lifespan.

EPDM membrane

EPDM (ethylene-propylene-diene monomer) membrane is a synthetic rubber roof covering that offers excellent resistance to extreme weather conditions, UV rays and ozone.

Its unique composition makes it perfect for flat roofs in the residential, commercial and industrial sectors.

Advantages of EPDM roofing

EPDM is a type of flat roof membrane with many benefits, making it an attractive choice for both home and business owners.

Exceptional durability and longevity

EPDM membranes are known to last a long time, with a lifespan that can easily go beyond 30 years, lasting even up to 50 years. It is resistant to UV, ozone and climatic variations, meaning it will retain its physical properties over long periods of exposure.

Resistance to extreme weather conditions

Since it is a type of synthetic rubber, EPDM roofing can withstand extremely cold or hot temperatures without cracking, deforming or losing elasticity. It also offers excellent resistance to all precipitation – rain, snow or hail.

Easy installation and low maintenance

It doesn’t take long to install an EPDM membrane, and installation does not require the use of an open flame, which greatly reduces associated risks. Once installed, it requires very little maintenance. Regular inspections and minor repairs are usually enough to keep it up to par.

Positive environmental impact

EPDM is an environmentally friendly choice because it lasts a long time, reducing the need for frequent replacement, and because it is recyclable. EPDM membranes can also be used to create white roofs, which help reduce air-conditioning costs and the overall carbon footprint of your building.

How to install an EPDM membrane

It is important to install EPDM roofing membrane correctly and precisely to guarantee that it will be strong and last a long time. Certified roofers explain.

1. Surface preparation

The first step is to carefully prepare the roof. This means making sure that the surface is clean, dry and free of debris, and any irregularities or sharp objects have been removed, to avoid puncturing the membrane.

2. Placing the membrane

The EPDM membrane is then unrolled and spread over the roof surface. At this stage, it’s important to let it sit for a few hours so that it can acclimatize and relax. This will reduce the risk of wrinkles or tensions in the material.

3. Attaching the roof covering

There are several possible ways to attach an EPDM membrane, depending on the type of roof and the manufacturer’s specifications. The most common methods include fastening it to the roof edges, or full adhesion to the roof surface.

4. Sealing the joints between strips

The joints between the EPDM membrane strips need to be sealed with a special adhesive tape or waterproofing liquid so they will be completely waterproof. This step requires high precision to prevent any roof leaking.

5. Finishing and details

Roof elements such as ventilation ducts, chimneys, etc. require special attention. Pre-formed parts or in-situ molding techniques can be used to create a watertight seal.

How to take care of an EPDM roof

EPDM roofing is known to be durable and to provide effective, long-term protection for flat roofs. However, as for all roof coverings, proper maintenance will maximize its longevity and performance.

  • Regular inspections: We recommend carrying out a visual inspection of your EPDM roof at least twice a year, ideally in spring and autumn. It’s important to detect any problems like cracks, bubbles or signs of wear before they become serious.
  • Cleaning: EPDM roofing surfaces should be cleaned regularly to remove dirt, debris and leaves, which can trap moisture and encourage the growth of algae or moss.
  • Drainage: Make sure your roof’s drainage system is working properly. Gutters and downspouts should be cleaned regularly to avoid blockages that could cause water accumulation.
  • Repairs: If you notice small holes or cracks in your EPDM membrane, we recommend that you call in a professional.

How to Manage Snow Accumulation on a Roof

Winter has arrived in Quebec, and beautiful white snow along with it. But picturesque winter scenes can quickly turn into a concern when you consider just how much damage snow accumulation on a roof can do.

Many businesses and residents of the province are unaware of the dangers linked with snow on a roof. In fact, few building owners know that just a few inches of snow piled on top of a roof can weigh several hundred kilograms.

Is your roof ready to handle that much weight in snow? The reality is that many roof structures are not built to withstand that much of a load, making a snow removal service essential.

How much snow can your roof support? What can you do to protect your roof from snow build-up in winter? Duro-Toit answers these questions below.

Snow accumulation on a roof: risks and dangers

Snow build-up can significantly add to the weight borne by your roof structure, especially when it is partially melted and wet. An overload can pose various risks and dangers:

  • Roof collapse: The most serious risk is roof collapse. Older roofs and those not designed to support heavy loads can collapse under the excessive weight of snow.
  • Leaks and internal damage: Snow accumulation on a roof can also cause leaks, leading water to infiltrate your building. Melting snow can seep through cracks or worn joints and cause long-term damage.
  • Ice formation: When snow melts and refreezes, it can create ice dams that prevent proper water drainage and increase the risk of building damage.

How much snow can a roof hold?

According to the Insurance Institute for Business and Home Safety, most residential roofs in good condition can handle 20 pounds per square foot of snow.

Another factor that to consider when determining whether the snow on your roof is approaching this weight limit is the type of snow:

  • Fresh snow: 10 to 12 inches of fresh snow equals about 5 pounds per square foot of roof. This means you can have a maximum snow load of 4 feet before the roof becomes strained.
  • Packed snow: 3 to 5 inches of “old snow” equals about 5 pounds per square foot of roof. More than 1 foot of snow may be more than your roof can handle.
  • Ice on the roof: A thin 1-inch layer of ice is equivalent to 12 inches of fresh snow! This is why it is so important to watch for ice dams and take care of them quickly.

We have put together at least one easy to use calculator to help you. Check it out in our article on how to calculate the weight of snow on your roof.

In a matter of seconds, you’ll know whether you need to clear your roof of snow or whether you can sleep soundly.

Snow weight accumulates quickly on flat roofs

Keep in mind that flat roofs are more susceptible to snow damage because the total weight accumulates faster. This is because melt water is more likely to freeze on flat roofs before it can drain off, contrary to pitched roofs.

Snow removal on flat roofs should be done more frequently to avoid serious structural damage.

What to do when snow starts to accumulate on your roof

To prevent snow from accumulating on the roof and avoid all the risks that this entails, you should commit to frequent snow removal. Snow removal is not a simple task and is often dangerous. Whoever is responsible for clearing snow from the roof should take all necessary safety precautions.

At Duro-Toit, we recommend contacting snow removal professionals if you have any doubts about your ability to safely remove snow from your roof.

Look for signs of roof damage

Sagging ceiling tiles or sprinkler lines, popping or cracking noises, blocked doors and windows, cracked walls or a leaky roof are all signs of an over-stressed roof.

Roof inspections are important

If you live in Quebec or anywhere where there is a lot of snow in winter, consider scheduling a professional roof inspection before the cold sets in. It’s best to confirm that your roof can handle the weight of the snow before it begins to fall.

And even if snowfall isn’t frequent where you live, it’s a good idea to contact an expert at least once a year to check the condition of your roof. Even rain or wind can cause problems if your roof is in bad shape.

Winter roof maintenance and preventive measure

Preventing snow build-up and maintaining your roof regularly will prevent damage and keep everyone safe during the winter months. Here are some practical tips from our Montreal roofers:

  • Install snow barriers: Snow barriers or snow guards can prevent snow from accumulating unevenly on your roof and sliding off in large quantities.
  • Use heating cables: Roof de-icing cables along gutters and roof edges can help prevent ice dams by making snow melt and drain off more quickly.
  • Proper insulation and ventilation: This helps maintain an even roof temperature and reduces the risks of repeated melting and refreezing.
  • Preventive snow removal: Consider removing snow from your roof to avoid excessive accumulation in the event of a heavy snowfall.

Pros and Cons of Roof De-Icing Cables

A common problem for building owners in snowy climates is the formation of ice dams on their roofs.

Ice dams are build-ups of ice and snow on the edges and eaves of a pitched roof. Ice dams can result in beautiful icicles, but they can also damage the roof, break gutters and cause water infiltration.

Several strategies have been developed over the years to prevent the formation of ice dams and the resulting property damage. One of the most popular strategies is roof de-icing cables.

In this article, Montreal roofers explain how ice dams form and how roof de-icing cables can help counteract the process.

What is roof de-icing cable?

A roof de-icing cable, also known as a roof heating cable or heating wire, is a roofing system designed to prevent ice and snow build-up on roofs, gutters and downspouts.

A heavy-duty electric cable is energized to generate heat. This heat prevents ice from forming and melts snow to preserve the roof structure and prevent potential damage caused by ice build-up.

How can roof de-icing cables help prevent ice dams?

Roof de-icing wires use electrical resistance to generate heat, melting pathways through the snow and ice on the roof. The channels allow meltwater to run off instead of freezing into ice dams or seeping into the roof. 

Please note: De-icing cables cannot melt all of the snow on the roof or completely prevent ice dams. Roof snow removal is still important when there is a thick layer of snow, even if the roof is equipped with de-icing cables.

Advantages of installing roof de-icing cables

If the de-icing cables are good quality and are installed by certified professional roofers, they can certainly minimize the water accumulation that causes ice dams and help slow their growth. They are generally placed in patterns along eaves, around chimneys and skylights and in gutters or drainpipes.

Although de-icing cables aren’t a permanent solution, they are an excellent choice for homeowners who need a quick solution. They cost much less than the roofing work needed to seal attic leaks, install proper insulation and create appropriate roof ventilation systems.

There are 4 main advantages of to installing roof de-icing cables:

  1. Prevention against ice formation and ice dams
  2. Protection against structural damage caused by the weight of snow
  3. Reduced maintenance and repair costs
  4. Improved safety

Choosing the right type of de-icing cable

Selecting the right type of de-icing cable will ensure that your roof is effectively protected against the harsh elements during winter. There are several different types of heating cable on the market, each suited to specific applications and climatic conditions.

Types of heating cables

  • Self-limiting heating cables: These cables are designed to adjust their heat output according to ambient temperature. They are ideal for climates where temperatures vary dramatically.
  • Constant wattage heating cables: These cables provide a constant amount of heat and are often used in areas where temperatures remain uniformly low.
  • Temperature-controlled heating cables: Fitted with sensors, these cables adjust their heat output according to weather conditions, making them energy-efficient.

Choosing the right cable for the building structure

  • Roof type: The choice of cable depends on the type of roof (slate, tile, metal, etc.). Some cables are better suited to specific surfaces than others.
  • Roof layout: Consider roof features such as slope, valleys, gutters and downspouts. This will influence the type of cable and installation method you choose.

Choosing a cable to suit the climate

  • Intensity of winter conditions: Regions subject to heavy snowfall and extremely low temperatures (like Quebec) will require sturdy, high-performance cables.

Roof heating cable installation

Installing a roof heating cable is a process that requires precision and attention to detail. Here’s a step-by-step guide to installing de-icing cables. Remember, always follow the manufacturer’s instructions!

1. Preparedness and safety

Start by reading the manufacturer’s instructions carefully. Each cable type may have specific installation requirements.

Make sure you have all necessary tools and materials at hand.

Switch off the power supply to the installation area and use appropriate safety equipment.

2. Planning the layout

Calculate the total cable length required, remembering to measure gutters, downspouts and problem areas on the roof.

Plan where the wiring will cross the roof, making sure to cover areas where ice and snow tend to accumulate most often.

3. Installing the de-icing cable

Start by securing the cable along roof edges, in gutters and around downspouts. Use the fasteners and clips supplied by the manufacturer.

Make sure the cables don’t cross each other and are distributed evenly.

Maintain the recommended spacing between cable loops for even heat distribution.

4. Electrical connection

Connect the cable to the electrical system according to the manufacturer’s instructions. If you aren’t sure how tot do this, exercise caution and call in a qualified electrician.

If your system is equipped with a thermostat or sensor, you’ll need to install this as well.

5. System test

Once installation is complete, turn the power supply back on and verify that the system is working correctly.

6. Post-installation maintenance

After installation, inspect the system regularly for any flaws or damage.

Installation of heating cables: safety and regulatory compliance

Installing roof heating cables involves following strict safety procedures, including disconnecting the power supply and using protective equipment. Work at heights must be carried out using fall-prevention equipment, and you must never attempt it alone. Be sure to respect the wire spacing recommended by the manufacturer to prevent overheating and reduce the risk of fire.

When installing heating cables, you must comply with electrical and building regulations, using certified equipment that meets established criteria for safety and quality. To guarantee that your cables are installed correctly, call on qualified professionals.

Install de-icing cables to protect your roof during the winter!

It’s very important to understand that roof de-icing cables cannot prevent ice dams from forming or eliminate them completely. They simply melt channels through the dams to help meltwater flow off the roof. To prevent ice dams from forming in the first place, you must address the root of the problem—an overheated roof caused by heat leakage from inside the house and/or a lack of maintenance in specific weather conditions.

Thankfully, Duro-Toit roofers are here to help homeowners whose roofs are prone to ice dams. After inspecting the roof, we will suggest a customized approach that includes all of the work needed to keep your roof at the ideal temperature.

Roofing Maintenance: Complete Checklist

Whether it’s your house, your condo or your business premises, the condition of your roof has a direct impact on your building and your well-being.

A worn out and unmaintained roof can cause a lot of problems, including leaks and insulation defects, which can lead to high heating costs.

Being aware that your roof needs to be taken care of is a good thing, but how do you go about it? And when should you do it?

Find out now with Duro-Toit Montreal’s roofers practical roof maintenance checklist.

The 6 essentials of roofing maintenance

Do you want to protect your roof, but aren’t sure where to start? From cleaning and snow removal to regular inspections, discover 6 roof maintenance tips that will save you time and money!

1. Clean the roof with the right equipment

The roof of your home is the first line of defense against wind, rain, temperature changes and, of course, snow. Consequently, even a top-quality roof covering will be exposed to bad weather and possible damage. A few things must be done to ensure that your roofing retains both its appearance and its insulating properties.

Cleaning is an essential element of regular maintenance. When done on a regular basis, it gets rid of damaging debris such as leaves, branches, sand and moss. There are various ways to clean your roof. However, you should avoid using high-pressure jets or brooms, which can cause damage. For more information on the best cleaning  solutions for your type of roof, consult a roofing professional.

2. Waterproofing

Homeowners can protect their roof against moisture and leaks by applying a waterproofing product. This type of water or acrylic based protection is available in two forms:

  • Film-forming: once dry, it will form a protective film that prevents air and water from penetrating below its surface.

  • Pearl effect: as its name indicates, this environmentally friendly product helps to form droplets that run off the roof more easily.

Again, there are many different products on the market and it is important to consult a professional to choose a water repellent that is compatible with your choice of roofing membrane or asphalt shingles and will not alter its color or composition.

3. Moss treatment

As indicated earlier, the geographical location of your home, the amount of vegetation on the property and above all the humidity can often produce moss on the surface of the roof. Formed by algae or lichens, these mosses are extremely damaging because they store water, create cracks when it freezes and make the materials more porous and therefore more vulnerable to bad weather. A comprehensive roofing maintenance effort should include moss treatment.

4. Gutter maintenance

Maintaining gutters and downspouts is essential because all unwanted dirt and debris is drained through your gutters. If you neglect your gutters for a long period of time, the pipes can become blocked and damage your roof, exterior walls and other structural elements. A simple flush may be enough to clean them out. However, if there is too much buildup, a manual or high-pressure cleaning may be necessary to ensure proper drainage from your roof.

5. Snow removal

Ice and snow build-up is probably the most common cause of roof leaks and water damage in Quebec homes. This is in addition to the extra weight that often causes roof structures to collapse. Consequently, snow removal during storms is an essential step for maintaining your roof!

If you live in the Greater Montreal area, you can have your pitched roof snow removal or flat roof snow removal done by Duro-Toit.

6. Roof inspection

Remember, sometimes the signs of deterioration of a roof are imperceptible. You’ll need a roofing expert to determine the health of your roof. A quarterly inspection is recommended to verify whether your roof needs maintenance, and whether you have:

  • Peeling flashing
  • Granular loss
  • Missing shingles
  • Curling shingles
  • Cracked shingles

If a professional inspection results in the detection of damage, you will be able to take action more quickly to avoid the spread of any weakness or flaws that could result in the need for more complex roof repairs or a complete roof replacement.

When should your roof be serviced?

Doing maintenance on your roof is essential for effective building management, whether for a house, condo, building or commercial space. Maintenance done by professional roofers will extend the life of your roof and thus help maintain the integrity of the building, making it a truly worthwhile investment that will save you money in the long run.

Roofing maintenance should be done at the following times:

When your roof shows signs of wear

As soon as your roof appears to show signs of wear, which could be indicated by an uncomfortable change in temperature, abnormally high heating costs, visible deterioration of the coating or traces of moisture, you should have a roof inspection done. Professional roofers will be able to tell you what type of roof maintenance makes the most sense for the building.

Depending on the case, you may be able to fix the problem by repairing only the damaged portion of the roof, by removing the obsolete components and replacing them with new materials. The work may also involve simply sealing leaks or installing new sealants or better insulation.

Repairing or adding vents is also a great solution for roofing systems that are prone to ventilation problems. Investing in the installation of a new unit will be much less expensive than having to do a complete roof restoration.

Before winter arrives

Quebec’s climate is harsh on roofs, which need to survive strong winds and the weight of snow and ice in winter. To avoid Mother Nature’s wrath, roofing maintenance begins with careful winter preparation. Some roofing companies, like Duro-Toit, offer roof winterization services. Avoid any unpleasant surprises and make an appointment before the first snow storms hit!

During winter, snow can often build up in large quantities. It is common to see cracks, leaks, structural deformities or even complete roof collapses. We recommend hiring a professional to remove snow and ice from your roof, to limit the risk of injury.

At regular intervals

Roofing maintenance involves a certain amount of vigilance. You should have an expert inspect your roof every three to six months, or after bad weather.

Cleaning the gutters is important, as well as checking the storm drains, to be sure they are doing their job and draining water and debris.

Adding gravel to asphalt roofs is a sure way to protect them from the sun’s destructive rays. In fact, this simple roof maintenance trick will slow down the contraction of the asphalt during major temperature variations and make your roofing last longer.

Let experienced roofers take care of your roof!

In short, regular roofing maintenance is essential if you want to keep your roof in good condition for years to come! That said, roofing work has to be done at height, so it is safer to rely on professional roofers. To learn more, contact the experts at Duro-Toit today!

Condo Roof Replacement: What You Need to Know

Condominium roof renovation and repair is an example of collaborative property management. There are many questions that need answering when replacing a shared roof: how to find the right roofers, when to do the repairs, how to plan a budget, figuring out what type of repairs to do, and so on.

If you’re thinking of re-roofing your building, we can help! Montreal roofers present a comprehensive list of factors to consider at your next meeting of the syndicate, so that you can accomplish a successful condominium roof renovation.

What does condominium roof renovation involve?

Replacing a shared roof means completely or partially renewing the roofing of a building owned by several co-owners.

In the context of co-ownership, the building roof is considered a shared part of the building, which means that the maintenance and renovation of the roof are the collective responsibility of the co-owners, organized within the syndicate of co-owners. The aim of condo re-roofing is to restore the roof’s waterproofing, insulation and durability, thus preserving the integrity of the building as a whole.

When is it time to re-roof your condominium?

Knowing when to undertake condominium roof renovation is an important decision which has an impact on the entire building’s lifespan. There are several signs that it might be time to take action and renovate the roof:

  • Water infiltration
  • Moisture stains on the ceiling
  • Missing or damaged tiles or shingles
  • Visible wear of roofing membrane
  • Thermal insulation problems.

If repairing and maintaining your roof is no longer enough, it may be time for a complete overhaul. After all, a roof’s lifespan is not infinite. If this is the case for your condominium building, put your trust in certified roofers.

Seasonal and weather considerations

Choosing the best time to undertake a condominium roof renovation involves taking seasonal and weather considerations into account.

In general, spring and summer are times of year where the weather is favorable for this type of work. It’s best to avoid doing roof repairs in the winter, when coping with extreme cold and heavy snow can add to the cost of the project.

Collaborative planning to avoid costly emergencies

Condominium roof renovation is a major project that requires careful planning and close collaboration between the syndicate of co-owners, the co-owners and your chosen construction professionals.

Rather than waiting to react to problems once they become urgent, take a proactive approach and establish a condominium roof renovation schedule based on signs of wear and tear, the age of the roof and the financial forecasts of the condo contingency fund.

By involving all stakeholders early in the planning process, you avoid costly emergencies, delays and unexpected disruptions.

Condo roof maintenance

Whether you’re a concerned condominium owner or a board member, understanding how roof maintenance works in a condominium will bring you one step closer to ensuring a safe and comfortable building for all residents.

Distinction between “shared common areas” and “private areas”

In a condominium, some building elements are shared by all co-owners, including corridors, staircases and the roof. Private areas, on the other hand, refer to the individual elements owned exclusively by each co-owner, including balconies, parking spaces and windows.

Maintenance responsibilities of the condo syndicate of co-owners

According to the Civil Code of Quebec, the condo syndicate is legally responsible for maintaining shared common areas, including the roof. This responsibility includes planning, organizing and supervising all repair and maintenance work on the roof.

However, co-owners also have maintenance responsibilities, which include maintaining and repairing their individual sections, such as units, windows, balconies etc.

Authorizing the work

Authorization to do condominium roof renovation must first be granted by the syndicate. The syndicate is generally made up of the assembly of co-owners and a Board of Directors. Each member’s decision-making power is proportional to their relative value in the co-op. For this reason, it is necessary to consider all the possible consequences that condominium roof renovation could have on both the condominium and its occupants.

To get approval for the work, consult the various members of the syndicate and set dates that suit as many people as possible. Once the general points have been discussed, a majority vote will determine the final decision.

Formalities and updates to the registration

The Board of Directors is responsible for ensuring compliance with building standards and regulations when the time comes for condominium roof renovations. The board is also responsible for managing financing, choosing professional roofers, negotiating and coordinating the work, and communicating with individuals on-site.

The board will also be responsible for ensuring the safety of all residents, and the integrity of the building. Any changes or modifications, including those required for roof maintenance, will have to be updated in the condo register, where applicable.

Finally, every aspect of the planning and execution of the work may be subject to change, according to the specifics of the deed of incorporation, the building by-laws and the description of the fractions (ownership rights).

Contingency condo fund

To finance condominium roof renovations and other major expenses, the syndicate of co-owners usually creates and manages a contingency fund. This fund is fed by monthly condominium fees paid by all co-owners.

Condo fees are calculated on the basis of various factors, including the estimated cost of major repairs and replacement of shared common areas. The syndicate of co-owners generally uses a predictive evaluation to estimate future costs for re-roofing and other necessary work.

The funds collected through condominium fees are then paid into the contingency fund to cover future expenses related to shared maintenance responsibilities.

Spending and financial planning

Whether you’ve been a co-owner for years or are new to this type of shared property, you pay what are commonly known as “condo fees” every month. This monthly charge usually covers all operating expenses, as well as your contribution to the residence’s contingency fund. As the building’s roof is considered a shared common area, this is the fund that will be used to finance condominium roof renovations.

If the condo fund is not sufficient to cover all the work, additional billing costs will be divided according to the value of each member’s private portion in relation to the total value of all the private portions of the property.

To save costs, it is never recommended to rely on friends or relatives to do roof repairs. Instead, call on experts to do condominium roof renovations and be sure to get several quotes so that you can compare possible contracts. This is the best way to get a good price without compromising on the quality of the work or the safety of the site. Remember, condominium roof renovations should never be carried out by amateurs.

Green Roof Benefits and Regulations

With growing environmental awareness and the need to rethink the way we build in urban areas, green roofs are emerging as an innovative, environmentally-friendly solution.

Also known as living roofs or vegetated roofs, these features offer remarkable ecological and economic benefits, harmoniously blending nature and urbanity.

In this article, our Montreal roofers present the different types of green roofs, explain the advantages they offer and outline how to maintain them.

What is a green roof?

Green roofs, also known as vegetated roofs or living roofs, are innovative architectural solutions that combine urban construction with natural vegetation.

Unlike traditional roofs that are covered in membrane or gravel, green roofs are covered, in whole or in part, with living plant vegetation. This garden-like cover transforms a roof into an oasis of green with remarkable environmental, economic and aesthetic benefits.

Types of green roofs

Green roofs fall into several categories, each adapted to specific objectives and varied contexts. The three main types of green roof are:

  • Extensive green roofs: These are characterized by a relatively thin layer of vegetation and hardy, low-maintenance plants. Typical species include grasses, mosses and succulents. Extensive green roofs are lighter and require less water and maintenance, making them suitable for larger buildings.
  • Intensive green roofs: Intensive green roofs feature a wider diversity of plants, including trees, shrubs and even entire vegetable gardens. This variant obviously requires more maintenance and a more robust support structure due to the increased weight of the vegetation and substrate.
  • Semi-intensive green roofs: These combine features of both extensive and intensive green roofs. They offer a greater variety of plants than extensive roofs, but require less maintenance than intensive roofs.

The components of a green roof

The structure of a green roof is made up of several interdependent components that work together to create a thriving ecosystem.

  • Substrate: The substrate is the artificial soil placed on the roof to support plant growth. It provides nutrients to the chosen plant species while draining water properly.
  • Plants: The species of plants you choose for a green roof depend on the type of roof and local environmental conditions. Roof plants must be able to thrive in specific rooftop conditions, which usually involve exposure to sun and wind, and significant temperature variations.
  • Drainage system: Green roofs require an effective drainage system to eliminate excess water and prevent stagnation. Proper drainage ensures that the substrate remains well aerated and that plants receive the right amount of water.

Green roof regulations in Quebec

In Quebec, green roofs represent a promising solution to mitigate the environmental issues associated with urbanization. However, the regulations governing these green installations are still under development. Here’s an overview of current legislation and the role played by the Régie du bâtiment du Québec (RBQ) in regulating green roofs.

The role of the Régie du bâtiment du Québec (RBQ) in regulating green roofs

Although roof construction legislation is not specific to green roofs, the Building Act and the RBQ Standard Guide for Selection, Installation, and Maintenance of Plants for Green Roof Systems provide guidance to ensure the safety and viability of these environmentally-friendly features.

Technical criteria and standards for green roof construction

The RBQ’s technical criteria are designed to ensure that green roofs are safe, functional and durable. These include ethe following:

  • Fire safety: Since vegetation is flammable, builders have to take measures to minimize the risk of fire and facilitate access for firefighters.
  • Load-bearing capacity: Green roofs impose an additional load on the building structure. The RBQ has established maximum permissible loads to prevent any risk of overloading.
  • Waterproofing and drainage: Builders must include provisions to prevent water infiltration and stagnation, which could damage the roof structure.
  • Maintenance: The technical guide includes recommendations for the regular monitoring and maintenance of green roofs, to verify that they are functioning efficiently.

What are the benefits of green roofs?

Although installing a green roof generally costs more than installing a traditional roof, even though you could be eligible for a green roof tax credit, there are many benefits to offset these costs.

Better rainwater management

Green roofs absorb almost 80% of rainwater in their soil. This water is later soaked up by the plants, eliminated slowly through the drainage layer, or it evaporates.

This process delays the flow of rainwater into the storm sewer system, which helps to stabilize groundwater levels, decreasing the peak load on the sewer system and reducing the risk of flooding. It also purifies the rainwater by removing various pollutants.

Increased biodiversity

The plants on a vegetated roof can provide an ideal habitat for various species of birds, butterflies and insects, which is particularly helpful in urban areas that are mostly made up of concrete and asphalt.

Improved air quality

Green roofs can combat air pollution, since plants filter the harmful airborne particles and gases emitted by cars and factories.

Mitigating the heat island effect

Green roofs reflect more sunlight and absorb less heat than traditional roofing materials. A living roof can help cool down urban areas in summer.

Reducing ambient noise, outside and inside the building

Vegetation provides excellent acoustic insulation for flat roofs, because it absorbs sound waves. It has been proven that a 12 cm thick layer of vegetation can reduce airborne sound by almost 40 dB.

So, a green roof can act as an acoustic barrier for your building by absorbing sound. This means it can help you provide a quieter environment both inside and outside your building.

More leisure space

A green roof provides additional space that can be used to create a vegetable garden or a terrace, or simply kept as a pleasant natural environment.

With access to a new open-air space that can be used for meetings or relaxation, your employees will be happier at work.

More energy efficient

Increasing the R-value (a measure of a material’s resistance to heat flow) of the roofing system and lowering the roof temperature reduces the building’s heating, ventilation and air conditioning needs, resulting in significant energy savings.

This also affects the lifespan of heating and air conditioning systems, because they will undergo less strain.

Over its estimated 40-year lifespan (another benefit), a green roof could help you save on a numerous expenses. Of course, the benefits of each green roof depend on design, geographic location, environment and the building itself.

Certified roofers are the best people to tell you what you really need!

Increased property value

A living roof can also increase property value, particularly in urban areas where green space is scarce.

With its 40-year lifespan, a green roof is an excellent selling point, because the future owner will probably not need to do any commercial roof repairs for a long time! Living roofs last longer because the plants protect the flat roof membrane from UV rays and extreme heat.

How to maintain a green roof

Maintaining a green roof is essential to ensure that it lasts a long time, functions efficiently and looks good. While offering many advantages, these types of roofs do require special attention according to the types of plants chosen and the season.

Maintenance according to the type of vegetation

Green roofs are home to a variety of plants, each with their own growing requirements. Before selecting plants for your roof, assess the amount of maintenance you’re prepared to do. Mosses and succulents are among the least demanding species, while a vegetable or flower garden will require more regular effort.

Watering frequency according to plant type

Watering frequency depends on the type of plants on your green roof. Some plants, like orpine, are drought-resistant and can survive without frequent watering. Others, like vegetables and flowers, will definitely require regular watering.

Pest management

Just like traditional gardens, green roofs can be vulnerable to pests and parasites. Grubs, insects and birds can damage vegetation. If you notice any signs of infestation, you’ll need to consult a landscaping professional who can identify the problem and implement appropriate prevention or treatment measures.

Protecting your green roof in winter

To ensure that your green roof lasts through the winter, choose plants adapted to your region’s climate (especially in Quebec). Cold-hardy species require less care when preparing for the winter season. You can be confident that your roof is designed to withstand winter conditions by following the recommendations of a professional.

Duro-Toit can answer your questions about green roofs

How Much Does a Flat Roof Cost?

When it comes to building or renovating a building with a flat roof, one of the first questions that comes up is: how much will it cost? By understanding all costs associated with installing a flat roof, you can plan a realistic budget and make good decisions.

In this article, our roofers present the different factors that can affect the price of constructing a new flat roof.

What does a flat roof cost per square foot?

The cost-per-square-foot approach is widely used in the construction industry to determine the price of a flat roof. This method offers a convenient way to compare prices and obtain a general budget estimate.

Based on the experience of our roofing contractors, the average cost per square foot for a flat roof in Quebec can vary from $10 to $40. This estimate is based on several factors, which we explain below.

The price of a flat roof, depending on the type of covering

The right flat roof membrane system guarantees that your roof will be waterproof and your building will be protected from the elements.

Homeowners have many choices when it comes to choosing the right flat roof membrane. Of course, there can be significant price differences between different types of roofing.

TPO membrane

TPO (thermoplastic polyolefin) flat roof systems consist of a single layer of synthetic material with a reinforcing grid. The TPO membrane is usually tacked down or fully adhered to the roof substrate.

This type of membrane stands out for its exceptional durability, and is usually guaranteed for 20 years. However, the quality of this membrane is greatly influenced by ambient temperature. In areas like Quebec where cold temperatures are common, the joints between membranes can become brittle. Even so, TPO membranes remain one of the best-performing membranes on the market, as long as it is installed correctly and used under the right conditions.

The average price per square foot for a TPO-coated roof is estimated at $15 to $25.

EPDM membrane

EPDM is an acronym for ethylene propylene diene monomer, a type of flat roof membrane used mainly for industrial buildings. The best way to imagine this material is to compare it to the inner tube of a bicycle tire.

Waterproofing is achieved with a single layer of membrane. Although it is durable, this roof coating is not recommended if there will be a lot of traffic on the roof. It can be installed in several ways: mechanically attached, fully adhered or held in place solely by the weight of the gravel.

Like TPO membrane, the average cost per square foot is between $15 and $25.

Multilayer asphalt and gravel membrane

This type of roof covering is composed of several layers of superimposed felts saturated with hot asphalt, which is then covered with gravel to slow the contraction or expansion of the asphalt during extreme temperature changes.

This inexpensive waterproofing membrane does, however, require recurrent long-term maintenance and the lifespan of this type of flat roof is generally shorter. The use of large quantities of asphalt in multi-layer roofing is also less environmentally friendly, as the extraction and processing of bitumen is energy-intensive and generates pollutant emissions. What’s more, asphalt is not biodegradable and contributes to the longevity of landfill waste once it has reached the end of its life.

The estimated price for this membrane is $12 to $18 per square foot.

Elastomeric membrane

Elastomeric membrane coating is considered one of the most durable roofing membranes, and the best for Quebec temperatures. This waterproofing system is composed of two plies of heat-welded modified bitumen membrane which can be installed at any time of year. Installing elastomeric membrane on a flat roof is often considered a good investment, as it requires little maintenance and has an excellent lifespan.

Although elastomeric membrane contains bitumen, it is a highly environmentally-friendly solution in the long term, thanks to its remarkable durability and resurfacing capacity. It’s both an economical and environmentally friendly choice. The cost per square foot is between $20 and $25.

Flat green roof

A vegetated roof or “green roof” makes it possible to grow plants on the roof of a building, which also regulates its temperature.

The cost includes the expense of the waterproofing membrane that must be installed underneath, and can vary from $10 to $30 per square foot.

Additional costs and fees associated with flat roofs

Beyond the cost per square foot and the choice of cladding, various elements can influence the overall budget of a flat roof project. Keep reading to learn more!

Minor or major roof renovation?

Flat roofs are very common in urban areas like Greater Montreal. Many residential and commercial buildings have flat roofs that were installed decades ago, but unfortunately, flat roofs do not last forever. They need to be renovated periodically so that they continue to function as an effective barrier against the elements.

Of course, a minor renovation to replace the covering will cost significantly less than a major renovation that involves replacing the entire roof system. The more components that need to be renovated (insulation, ventilation, adding skylights), the more expensive it will be.

The size of the flat roof

It goes without saying that the larger the roof is, the more expensive it will be to construct or renovate.

On the other hand, keep in mind that the surface area that requires covering does not include any obstacles on the surface. Also, the larger and taller the roof, the greater the challenge of installation and handling materials and debris. It’s important to consider costs related to labor and tools/equipment (e.g. hoists) required to carry out the work, in addition to permits to block streets, etc.

Roof structure and decking

A flat roof requires a structure and decking that will support the system and mechanical components.

For flat roof projects, prefabricated structural components such as roof trusses with a slight slope can sometimes be used to cut costs, because completely flat structures require tapered insulation.

Flat roof ventilation

Proper flat roof ventilation is vital to preserve the integrity of the building and prevent problems. The National Building Code of Canada lays out ventilation requirements that owners and roofing contractors are obliged to follow.

When renovating or constructing a flat roof, part of the budget must be allocated to ventilation.

Flat roof insulation

A flat roof must be properly insulated to keep the building at a reasonable temperature. Part of the renovation or construction budget must go to insulation.

Vented flat roofs must be paired with insulation that supports the ventilation system. Generally, the system will require fans placed in strategic locations, openings and insulation with a high R-value.

Unvented flat roofs, on the other hand, have no ventilation system in the attic and must therefore be insulated from above using rigid insulation panels placed directly on the vapour barrier.

There are many types of insulation products available at a wide variety of prices. To choose the right one, it is necessary to thoroughly assess the properties and characteristics of each product.

The location of the worksite

When a roofing contractor prepares a quote, they always consider the location of the worksite in their estimate.

For example, building a flat roof in a remote area may involve additional transportation expenses for equipment, materials and labour that will need to be included in the bill.

Also, replacing a flat roof at the top of a 10-storey building can be more expensive than replacing the roof of a duplex, because getting the necessary materials to that height is a complex task that may require additional equipment.

Roof maintenance

While flat roof maintenance costs are not part of the installation price, it’s still important to remember that keeping a roof in good condition requires some investment.

Flat roof maintenance includes regular inspections and occasional snow removal. Neglecting to care for a flat roof will inevitably shorten its lifespan.

The roofing contractor

Generally, the cost of materials is relatively consistent from one contractor to another. However, hourly rates can vary considerably. Some companies provide warranties, use certified labour and have an excellent reputation, while others do not. It’s generally worth paying a bit more for high quality roofing work. Beware of prices that are too good to be true!

7 Steps to Building a Roof Deck

The roof deck was long considered an area that wasn’t good for much, but recently it has become a popular building addition with many perks. As it turns out, this relatively simple extension can transform a plain old flat roof into a functional, attractive and hospitable living space.

But wait a second before picking up that hammer! Building a rooftop deck demands technical skills, knowledge of the correct use of protective equipment and checking up on local legislation.

The best thing you can do to prepare yourself to build a roof deck is read this article by our Montreal roofers! We’ll tell you what you need to know before getting to work.

Why build a roof deck?

Building a roof deck on your own home can radically transform your daily life and improve your living environment.

Private outdoor space

A roof deck is your own personal outdoor space. It’s a secluded sanctuary where you can escape the hustle and bustle of everyday life and enjoy moments of tranquil relaxation, away from prying eyes. You can use it as a reading corner, a space for sunbathing or simply a place to relax with your loved ones.

Urban garden

If you live in the city, building a roof deck gives you the opportunity to create a rooftop garden. You can plant flowerbeds, add window boxes or shrubs in containers, and even construct larger containers for vegetables and herbs.

Uninterrupted view of your surroundings

A rooftop deck also makes it possible to enjoy a panoramic view of the city. Contemplate the bustling cityscape or the natural beauty of the surrounding area and take a break from the daily pressures of life. Sunrises and sunsets become unforgettable spectacles, and you can even climb up to your deck to admire the stars at night.

A place to socialize

A roof deck can quickly become a go-to place for family gatherings, parties with friends or relaxing moments as a couple. It’s an ideal place to hold barbecues, enjoy outdoor cocktails or simply share good times with the people you care about.

Increased property value

Building a rooftop deck can also add value to your property. As well as making your building more attractive, a well designed and maintained deck can be seen as an asset to potential buyers.

Regulations and permits governing roof deck construction

Municipal bylaws and standards for roof decks differ across municipalities. Factors that come into play include the location, height and visibility of your building, and what the building is used for.

It should be noted that buildings located within special zones where the land or property is considered to have heritage value will likely face restrictions to constructing a roof deck.

For more information and to find out whether you can install a rooftop deck on your property, consult our experts or visit your borough’s website.

Different types of roof decks

One of the great things about roof decks is that they come in all shapes and sizes, so there are plenty of options to choose from according to your own preferences and needs. It all depends on the type of building you have, the climate you are living in and what you want to use your rooftop deck for. With these things in mind, here are a selection of the most popular types of roof decks.


This type of roof deck is generally the simplest and least expensive to build. Once you’ve made the necessary structural modifications to your flat or pitched roof, you simply need to build a deck with adequate drainage. Treated wood is a very popular material for this type of rooftop deck.

Green roof

Green roofs are becoming more and more popular, especially in the city, as they allow you to enjoy an oasis of greenery and fresh air right on your own roof. With a green roof, you can take action against urban heat islands and improve the scenery while you’re at it!

However, considering the additional weight that this type of roof deck carries, it is critical to have a professional flat roof inspection done before beginning to build, to make sure your building’s structure is strong enough to support it.

And remember that planting a garden on a roof often requires the installation of a high-performance flat roof membrane and additional drainage systems to prevent water infiltration into the building.

Accessible roof deck

Accessible roof decks can be reached directly from inside the building. They are often equipped with a staircase or trapdoor. This type of rooftop deck is ideal for a relaxation area, leisure space or city garden.

Non-accessible roof deck

Unlike an accessible roof deck, a non-accessible roof deck is not intended for human use. Its main role is to improve thermal insulation and structural waterproofing. To this end, it is often covered with specialized construction materials like waterproofing membranes, gravel or roofing slabs that protect the roof from direct exposure to the elements.

Steps for building a rooftop deck

Building a roof deck is a complex project that demands careful planning and precise implementation. Here are the main steps to follow to successfully build a rooftop deck.

1. Assess feasibility

Before beginning your project, hire a flat roofing contractor to assess the feasibility of the idea and help you design reliable construction plans. A feasibility assessment will also involve verifying the strength of the existing structure to confirm that the roof can withstand the additional weight of the deck as well as furniture and people.

In addition to helping you design the plans and issue the specifications for your flat roof, a roofing professional will be able to give you reliable advice and inform you of the standards and regulations that apply in your area.

2. Obtain permits

Before starting work, make sure you obtain the necessary building permits from municipal authorities. Permit requirements vary according to location.

3. Prepare the roof

Preparing the roof is crucial to making sure your deck will be stable and strong. This step involves thoroughly cleaning the surface, inspecting and repairing any leaks or damage, and installing a quality waterproofing membrane to protect your building from water infiltration.

4. Install the deck

Now that your roof has been prepared, it’s time to install the deck. The deck structure can be made of wood, metal or composite materials, depending on your preferences and the requirements of the project.

Always try to opt for top-quality materials (elastomeric membrane, vapour barrier, treated wood, etc.). High-quality materials guarantee that your rooftop deck will last a long time and keep people safe as they enjoy the view on sunny days!

5. Waterproof the deck

Waterproofing is essential to protect your roof from the elements and avoid water infiltration problems inside the building. Apply a high-quality waterproofing product to the entire surface of the deck, making sure to seal all joints and connections.

6. Fittings and finishing touches

Once the structure and waterproofing are in place, you can fit out your new rooftop deck according to the plans you’ve drawn up. Install furniture, technical equipment (if any), plants or gardens, and any other elements included in the project design.

7. Final inspection

Before using your roof deck for the first time, check that everything is in place and ready to function. Check for effective waterproofing, structural soundness and compliance with building standards, and make sure there are no defects.

Important points when installing a flat roof deck

Although solid, the roof of a building or a house is still vulnerable. Altering its components will make it susceptible to bad weather, temperature variations and much more. As such, building a deck on top of a building will inevitably add weight to the structure, which could weaken it. Similarly, the screws, nails and tools used to assemble the deck can damage the roof covering, which can cause flat roof leaks.

For these reasons, leave the installation to experts. They will be able to take these aspects into account and determine the steps to follow to avoid deteriorating the siding and distribute the weight properly. They will also see if it is necessary to add rubber supports to shore up the construction.

Make sure your flat roof construction zone is safe

In addition to posing certain technical difficulties, this type of work is carried out at height. This implies considerable safety risks not only for the workers, but also for the passers-by and the occupants of the building.

For this reason, it is crucial to hire certified flat roofers to help you build your roof deck. They will establish a safety perimeter, take care of accident prevention and ensure proper waste disposal.

Finally, in addition to looking after their own safety when working at heights, roofing experts can also ensure the safety of your family and friends. They will be able to install the necessary fall protection, such as ramps or guardrails, when required.

How to Choose a Reputable Roofer :10 Factors to Consider

Having trouble finding the right roofer? Whether you’re installing a new roof or having your roof redone, it’s important to choose a roofing contractor carefully. You may think you’re meeting with a contractor who knows what they are doing, but there are things you should be aware of to be sure you’re on the right track.

Wondering which factors are important in choosing a reputable roofing contractor? Here are ten tips to help you discover and choose the right (and maybe even the best) Montreal roofers!

Factors to consider for choosing a good roofer

In the search for a good roofer, there are several specific factors you need to keep in mind. Here are ten tips for finding right roofer for your project:

Tip #1: Ask friends and family for recommendations

When looking for a certified roofer, it’s a good idea to start by asking around for recommendations. Talk to friends, neighbors, co-workers or family who have recently had roofing work done. They’ll be able to give you valuable information about the roofers they’ve worked with, including their reliability, professionalism and the quality of their work.

Personal recommendations can be an excellent way to find a trustworthy roofer, since you’ll be getting information from people you trust.

Tip #2: Use the Internet to find roofers in your area

The Internet is a valuable resource for finding roofers in your area. Search online using terms like “roofer in my area” or “qualified roofer near me” to get a list of local professional roofers to check out.

Browse their company websites to learn more about their skills, services and experience. Be sure to check whether these roofers have the right skills and materials for your specific roofing project.

Tip #3: Read online reviews and ratings

Once you’ve identified a few potential roofers, it’s essential to check their online reputation. Take a look at reviews and ratings left by previous customers on Google, the Yellow Pages and industry-specific sites. These comments will give you an insight into customers’ experience with each roofing service.

Look for positive comments related to work quality, on-time delivery and transparent communication. Be wary of professionals with recurring negative reviews or unresolved complaints.

Tip #4: Licenses and certifications

When choosing a roofer, it’s essential to check whether they hold a valid license, as this is an important indicator of the company’s legitimacy and compliance. Check with the appropriate authorities, such as the Régie du bâtiment du Québec (RBQ) in Quebec, to confirm that the roofer is registered and has an up-to-date license.

You should also check the roofer’s certifications. Specific roofing certifications, like those awarded by roofing materials manufacturers, are a sign that the roofer is a competent expert, professionally trained and recognized by the industry.

Les Couvreurs Duro-Toit holds numerous certifications demonstrating the quality of our work and customer satisfaction, including the Consumer’s Choice Award, which we have been given for the 4th year in a row.

Tip #5: Experience and knowledge

Experience is a key factor in finding a good roofer, as an experienced roofer has an in-depth knowledge of installation techniques, materials and safety standards. With experience, a roofer will be able to effectively manage potential challenges and guarantee quality work.

Ask any roofer you are interested in hiring how long they have been in the business and find out what types of roofing projects they have worked on. It’s always better to hire a professional who has completed a variety of projects and is familiar with different types of roofing.

Tip #6: Ask your roofer for references

In addition to being qualified, your roofer should also be able to show specific achievements that are similar to your current project. Different roofing contractors specialise in different types of jobs. For example, a roofer may be highly skilled in providing pitched roof services, but that doesn’t mean they have the experience to offer quality flat roof services.

Tip #7: Insurance and guarantees

Before signing a contract with a roofer, verify that they have professional liability insurance. This insurance ensures that the roofer will cover the cost of any damage to property or injuries sustained on site.

In addition, make sure the roofer offers a warranty to guarantee that the roofer will remain responsible for any problems related to the quality of their work for a specified period. Check the terms and duration of the warranty and make sure you understand the conditions.

Please note: A roofer’s warranty could be affected by the number of years they have been in business! Roofers normally provide a 5 to 10-year warranty, but if the company is relatively new, you may not be certain that it will remain in operation for the full length of their warranty.

Tip #8: Get Quotes from several roofing contractors

It’s very important to approach several roofing contractors and request quotes from all of them. In fact, it’s the first thing you should do when thinking about having your roof installed, repaired or renovated.

The Régie du bâtiment du Québec (RBQ) recommends that you compare a minimum of 3 estimates to make an informed choice. You will be happy to know that many roofers are willing to offer free quotes.

Confirm that the following elements are included in each roofing quote:

  • Worksite security measures
  • Waste management
  • Warranty on the work
  • RBQ license number
  • Liability insurance
  • Certifications (certified installer)
  • Workforce certification
  • Associations (CAA, etc.)

Once you have several quotes in hand, examine them carefully, taking your time to verify important points:

  1. Price: Make sure you understand what’s included in the estimate, and check whether any additional charges may apply to the total cost. Keep in mind that choosing the cheapest roofer does not necessarily guarantee the highest quality of work.
  2. Timetable: Check the timetables provided with each estimate. If you have specific time constraints, make sure the roofer can meet your requirements.
  3. Materials: Verify that the materials the roofer intends to use are good quality and appropriate for your project. Check whether the roofer can use any specific brands or types of materials (asphalt shingles, elastomeric membrane) that you have already chosen for your project.
  4. Services: Some roofers may include services beyond the basic roofing job, such as clean-up or waste removal after the work is done. Make sure you understand what’s included in the estimate and what isn’t.

Be wary of low quotes

When comparing estimates, be cautious of offers that seem abnormally low. Very low prices may be a sign of inferior workmanship, poor quality materials or a company seeking to attract customers by lowering their standards.

A professional, experienced roofer will offer a competitive but realistic quote. If an offer seems too good to be true, ask the roofer for an explanation. Consider the factors mentioned above and make a decision based on the quality of the work and the roofer’s reputation, not just price.

Tip #9: Check with the Office de la protection du consommateur

Think you’ve found the perfect professional roofer for all your roofing installation and renovation projects? You should still pause before signing the contract.

Now is the time to verify if there have been any complaints about this contractor. First, check with the Office de la protection du consommateur. Also, verify their RBQ license number online one more time, as some unreliable companies may use a false number.

You can also check to see if the roofer you are considering hiring is recommended by CAA Approved Residential Suppliers. This certification confirms that a roofer is top quality by evaluating customer satisfaction, the quality of their work, their communication with customers and their ability to stick to deadlines. A certified roofer will generally work hard to maintain their CAA status.

Tip #10: Make sure you hire a specialist and not a general roofer

Most of the best roofers are specialists, not generalists. While there are many different types of contractors who may seem capable of doing a roofing job, we recommend professionals who focus specifically on roofing (installation and repair), roof insulation, roof framing, tinsmithing and other aspects of roofing.

You know you’ve found the right roofer if they are a professional who is up to date on the latest developments in the field (best materials, roof ventilation, roof sealing systems, best installation practices, etc.). Make sure your roofer has roofing systems certifications from several manufacturers and organizations. This can make a major difference in getting the job done right.

Les Couvreurs Duro-Toit: the best in Montreal?

Make sure you hire a contractor that will give you a good return on your investment!

Better references, better quality/price ratio, better record with the Office de la protection du consommateur (OPC) – there are many things that can influence your decision when choosing the right roofing contractor. Be careful and don’t compromise! A poorly installed or badly renovated roof can cause you many problems and significant additional expenses later on.
