More than just a symbol of protection and comfort, the roof of any building requires special attention if you want it to do its job well. Especially if you have an old roof that has withstood the elements for many years, it may be time to consider a restoration.

A well-maintained roof can significantly improve the energy efficiency of your building. However, roof restoration requires careful planning and deliberate, step-by-step execution to be successful.

In this article, the experts at our Montreal roofing company guide you through the entire roof restoration process and offer valuable advice on deciding when to restore your roof, which steps to follow to complete the project successfully, and how much roof restoration could cost.

When is it time to restore your roof?

Before beginning a roof restoration, you need to decide whether your roof really needs to be renovated (or replaced). There are many signs that could indicate your roof needs work, and it’s important to note these early and take action to prevent more serious problems in the future.

Signs your roof needs restoration

• Water leaks and seepage: If you notice water stains on the ceilings or walls of your home, this may be caused by a leaky roof. Water infiltration can damage the structure, insulation and other components of your building. This is a sign that your roof needs immediate attention.
• Broken or missing shingles: Broken or missing tiles, shingles or other roofing materials are clear signs that your roof needs a restoration. Gaps in the roofing cover can allow water to penetrate the building and cause damage.
• Deterioration of roofing materials: If you notice signs of wear on your roofing materials, like buckling, cracks or discoloration, it’s time to consider a roof restoration.
• Loss of energy efficiency: If your energy bills are rising for no apparent reason, it could be due to poor insulation. Re-insulation can improve your building’s energy efficiency.
• Advanced age: If your roof has exceeded its normal lifespan (generally between 20 and 30 years, depending on the material), we recommend considering a restoration, even if there are no obvious signs of damage.

The benefits of preventive roof repair

There are several advantages to preventive restoration. By acting before problems worsen, you can save money in the long term and avoid more costly repairs. Preventive restoration can also make your roof more watertight, improve insulation and help preserve the structure of your building.

How to repair an old roof in 8 steps

The process of renovating an old roof requires careful planning and respect for a specific procedure. There are 8 steps to follow to successfully repair your roof.

1. Assessment of current roof condition

Before starting any work, you need to carry out a complete assessment of your roof’s current condition. This involves inspecting the framework, roofing materials, flashing and any signs of damage. Identify damaged areas, leaks and signs of deterioration to determine the extent of the work required.

2. Planning and design

Once the assessment is complete, you can start planning the restoration. Choose roofing materials according to the local climate, how you want your building to look, and durability. Remember to consider roof insulation so that you can improve your building’s energy efficiency. Draw up a detailed plan that includes everything from materials to architectural layout.

3. Site preparation

Prepare the site by making the area secure and doing whatever is necessary to protect the immediate surroundings. Install safety barriers and protect windows and exterior fittings to avoid potential damage during the restoration. Make sure you have all necessary equipment.

Since roofing work involves working at heights, it’s best to leave it to a professional. At Duro-Toit, we have the equipment and experience to carry out work at heights in complete safety.

4. Demolition and disposal

The process begins with the removal of old roofing materials, such as tiles or shingles, making sure to respect safety regulations. Remove damaged layers and clean the surface in preparation for the installation of the new roof.

5. Renovation of the roof structure

If your roof structure is showing signs of deterioration, now is the time to make the necessary repairs. Reinforce beams, replace damaged parts and make sure the framework is strong and can safely support the new roof.

6. Insulation and ventilation

Take advantage of this opportunity to improve your sloped roof ventilation and insulation. You can add high-quality insulation material between the rafters to improve the energy efficiency of your home or building. Make sure your roof also has adequate ventilation to prevent moisture build-up.

7. Installation of the new roof

Choose roofing materials that will function correctly for the type of building, and look good too. Whether you opt for traditional shingles, asphalt shingles or other modern materials, be sure to follow installation instructions for a watertight, long-lasting roof.

8. Finishing and inspection

Once the new roof has been installed, you’ll need to do some careful finishing to ensure that it remains watertight. Do a thorough inspection to make sure everything is up to standard and every detail has been looked after.

How much does roof restoration cost?

One of the key elements to consider when restoring your roof is the total cost of the project. Factors influencing cost can vary considerably. The following are the main points to consider:

Factors influencing the cost of roof renovation

• Roof size and shape: The size of your roof is an obvious factor influencing cost. Larger roofs require more materials and labor, which will increase expenses. The complexity of the roof configuration, such as slopes, dormers or chimneys, can also influence the cost of roof restoration.
• Choice of materials: The type of roofing materials you choose plays a role in determining the overall cost. Top-of-the-range materials may be more expensive to buy, but can offer greater durability and look better for a longer time.
• Additional work: If the roof structure needs repairing, insulation needs improving, or items such as rain gutters and vents need replacing, this additional work will add to the overall cost of the restoration project.
• Accessibility and safety: If your roof is difficult to access or workers need to take extra safety precautions to do the job, this can add to the cost. Sometimes it is necessary to take measures protect your property during the work, which could also influence the overall cost.

Budget for roof restoration

To estimate the budget for your roof restoration, you can:

• Ask for quotes: Get detailed estimates from several roofing contractors. This will give you a clearer idea of the costs associated with your specific project.
• Calculate the cost of materials: Calculate the approximate cost of materials required, based on the surface area of your roof.
• Include extra costs: Don’t forget to include additional costs such as structural repairs, insulation, vents, rain gutters and finishing.
• Allow a margin: It’s a good idea to allow a margin for unexpected expenses and cost variations. In general, we recommend a margin of 10% to 20% of the total budget.
• Look for grants and financial assistance: Find out about any grants or financial assistance programs available for roof restoration. These initiatives can help reduce your expenses.

Roofing restoration grants in Quebec

If you’re planning to renovate your roof in Quebec, there are several financial assistance programs available to help finance your project. Here’s an overview of the different resources available to help you finance your roofing project.

As global temperatures continue to rise, urban areas are faced with an increasingly problematic issue: heat islands. These are areas where heat accumulates thanks to the dark, heat-absorbing surfaces of buildings and infrastructures, leading to higher temperatures in cities than in surrounding areas.

White roofs are an innovative solution to counter the harmful effects of urban heat islands. They are a promising alternative for cities that need to improve their resilience to the rising temperatures associated with climate change.

In this article, Montreal roofers explore the world of white roofs in detail, explaining what they are, how they work, and the materials used to build one.

What is a white roof?

White roofs are roofs covered in a pale coating, contrary to traditional roofs, which are generally dark. White roofs use special materials to reflect the sun’s radiation back into the atmosphere, so that the roof and building do not absorb as much heat.

How do white roofs work?

A white roof is covered with a reflective coating that is usually white or very pale. This special surface reflects a large proportion of the sun’s rays, reducing the amount of heat that is absorbed by the roof. As a result, the surface temperature of a white roof is significantly lower than that of a regular black roof, even on sunny days. By maintaining cooler temperatures, a white roof helps to mitigate the formation of urban heat islands and also improve indoor comfort.

What are white roofs made of?

A variety of materials can be used to create a white roof, each with its own durability, cost and level of reflectivity. These are a few common products used in the construction of white roofs:

• Reflective membranes: These PVC or EPDM rubber (ethylene propylene diene monomer rubber) membranes are specially designed to reflect solar radiation. They are applied to the existing roof surface.
• Reflective paints: Painting a roof with special reflective paint is an easy way to transform a regular roof into a white one.
• Reflective coatings: Special coatings made with reflective materials like ceramic or silica can be applied to the roof surface to enhance its solar reflectance.

White roof vs. black roof: what’s the difference?

Compared to regular black roofs, white roofs offer numerous ecological advantages. By reducing heat absorption, they help to lower the temperature of buildings and urban spaces, which minimizes the risk of creating urban heat islands. White roofs also reduce energy consumption levels related to air conditioning, helping to cut greenhouse gas emissions and protect the environment.

In addition, white roofs extend roof lifespan by reducing the wear and tear related to high temperatures, meaning fewer roof repairs and replacements are necessary. They also improve indoor comfort, providing a cooler environment in summer without high associated energy consumption.

What are the advantages of a white roof?

The benefits of white roofs go far beyond their ability to control the formation of heat islands. In fact, they are a high-performance, durable and environmentally friendly option.

Significant energy savings

When a roof absorbs the sun’s heat, that heat is transferred to the building via thermal conduction. This means that the temperature inside the building will be warmer, and more energy will be needed to cool the rooms.

By reflecting the sun, a white roof prevents heat from accumulating on the roof and creeping into the building’s structure. The building will stay cooler, which reduces the electricity costs associated with air conditioning. That’s why white roofs are synonymous with saving both energy and money!

Impressive lifespan

It’s important to remember that the main role of a roof is to protect a building from the elements. Fortunately, white roofs can do this effectively, and for a long time.

A white roof can protect roofing materials from repeatedly overheating from exposure to direct sun, thereby preventing related heat damage. In addition, the membrane used to cover white roofs remains highly flexible in winter, able to elongate over 300% in all directions even in temperatures as low as -40°C. It is also resistant to the wear and tear that can result in water infiltration.

Ideal for green roofs

Some white membranes are ideal for green roofs. Of course, you’ll need to check that the roof structure is sufficiently solid before installing a green roof, as it increases the roof’s load.

Reduced waste

Unlike many types of roof covering, some white roof membranes can be recycled.

And since white roof membranes are often more durable than asphalt and gravel membranes, they last longer and help reduce waste.

How much does a white roof cost?

Installing a white roof is an ecological and economical investment that offers long-term benefits. However, the initial cost can vary according to several key factors. These include:

• Roof area: The first factor affecting cost is the size of the surface to be covered. The larger the roof, the more material and time required.
• Type of material: The choice of material used for the reflective coating will impact the overall cost. Reflective membranes, special paints and reflective coatings have different levels of durability and the cost of purchase and installation will vary.
• Roof complexity: The architectural complexity of the roof can also influence cost. A pitched roof or an irregularly shaped roof will require the services of a certified roofer, which can increase the overall cost of the project.
• Accessibility: Roof access can also play a role in installation costs. A roof that’s difficult to access will require special equipment, and installation make take longer.

Although white roofs may represent a higher initial investment than black roofs, it’s important to consider the potential long-term savings and return on investment they offer.

Are white roofs the best solution for fighting urban heat islands?

Installing white roofs can greatly reduce urban heat islands. They are an excellent solution at a time when concern for the environment and individual well-being is sky-rocketing.

Some areas in large cities, including Montreal, are beginning to make white roofs mandatory on new flat-roofed buildings. While this type of roofing is not yet obligatory everywhere in the province or the country, white roofs are becoming a more popular choice all the time.

Asphalt shingles are popular with consumers not only because they look good, but also because they are durable and affordable.

However, installing shingles is a delicate process that requires skill and attention to detail. In fact, if you don’t have any experience in roofing installation, you could fall into one of the many pitfalls that await amateur roofers.

Don’t be discouraged! In this guide, our roofers offer valuable advice so that you can successfully install asphalt shingles.

How to cut asphalt shingles

When it comes to cutting asphalt shingles, there are several popular methods to choose from. Let’s take a look at the two most common: with a manual shingle knife or using a roofing air knife.

Shingle knife

A shingle knife is a popular tool for making precise cuts on asphalt shingles. We recommend following these basic steps:

1. Make sure you have a sharp hook blade. A dull knife can make cutting more difficult and less accurate.
2. Measure the desired length of asphalt shingle with a tape measure and mark it on the shingle.
3. Place the shingle on a stable, solid surface, making sure it is properly supported.
4. Hold the shingle knife comfortably, keeping your fingers away from the blade.
5. Apply firm, steady pressure to cut the shingle in a single stroke, following the line you made earlier.
6. Repeat this process for each shingle, making sure each cut is straight and precise.

Roofing air knife

Using an air knife can be a faster and more efficient option, especially if you have a lot of shingles to cut. Here’s how to use a roofing air knife to cut asphalt shingles:

1. Get a roofing air knife. Make sure the blade is clean and in good condition.
2. Mark the correct length of asphalt shingle using a tape measure and a pencil or piece of chalk.
3. Place the asphalt shingle on a solid surface and make sure it will not move or vibrate with the pressure of the air knife.
4. Position the air knife so that the blade is aligned with the line you have drawn on the shingle.
5. Squeeze the trigger and gently pull the blade across the shingle, applying constant pressure. Follow the line to make a clean cut.
6. Keep your hands and fingers at a safe distance from the blade while cutting.

Note: Whatever technique you use, remember to wear protective equipment including safety goggles and gloves to avoid accidents.

How to install asphalt shingles on a roof

Installing asphalt shingles is crucial to building a durable, aesthetically pleasing roof. Keep reading to learn how to install asphalt shingles from professional Montreal roofers.

Step 1: Gather the necessary materials and tools

First, gather all the materials you’ll need to install your asphalt shingles:

• Shingles
• Galvanized roofing nails of the appropriate length
• Plastic roofing cement
• Self-adhesive eave protection membrane
• Synthetic underlayment
• Valley and flashing protection (weatherproofing)
• Roof ventilators

To complete your project as easily and quickly as possible, equip yourself with appropriate tools:

• Roof-stripping shovel tool
• Shears (for cutting metal flashings)
• Chalk line
• Knife with hooked blade (for cutting felts and blanket rolls)
• Square
• Roofing hammer and/or pneumatic nailer
• Air compressor for use with pneumatic tools
• Caulking gun
• Tape measure
• Trowel
• Nail bar
• Personal protective equipment such as harnesses, ropes, runners, energy absorbers, anchors, goggles, and steel toe boots or steel caps

Getting all this equipment together can be complicated and costly for an amateur roofer. To make things easier, contact a roofing professional!

Step 2: Install the underlay system

Let’s assume that the old shingles have already been removed and the waterproofing membrane and flashings have already been installed.

Once your set-up is complete, draw a chalk line from the top to the bottom of the roof. This applies to the use of “3-tab” shingles, the most popular type of asphalt shingle, which are installed from the bottom up (the ladder pattern).

For laminated shingles, the installation procedure will be different. The first course of shingles (on the lower part of the roof) will be composed of 3 shingles, the 2nd course of 2 shingles and the 3rd course of 1 shingle.

Step 3: Install the asphalt shingles

Now you need to nail the shingles in place with an air nailer and trim the excess with a knife. Leave the excess strips slightly above the ridge, however, as these will be trimmed later.

When installing asphalt shingles, be careful to nail the shingles where indicated to ensure maximum pull-through resistance. Four nails per shingle are usually enough, but it is even better to use 6 nails for maximum long-term adhesion.

When the siding crosses the corners of a gable or other sloping area (valley), be sure to cut the shingles at an angle to reduce the risk of your roof leaking.

To keep the rows straight, we recommend drawing horizontal lines at regular intervals.

Step 4: Caulk

Next, caulk each joint and crack and use plastic cement to seal them off. While you’re at it, now is a good time to seal your chimneys, vents, roof ventilators and ridges as well, but remember to leave a free pathway for water to drain off your roof. 

Step 5: Cleaning and finishing

Finally, take the time to do a meticulous finishing job. This includes cutting off excess shingles and applying sealants.

Always remember to work safely

We must emphasise the importance of safety when installing asphalt shingles or doing any other work at height.

Always remember, this type of work involves adhering to building codes and respecting occupational health and safety standards.

It’s best when roofing work is carried out by a team of professionals after doing a roof inspection.

Asphalt shingles can wear out over time or from exposure to the harsh Quebec weather. If you notice broken, cracked or missing shingles on your building, act quickly to avoid bigger problems like water leaks or seepage.

Whether you’re a DIY enthusiast or you prefer to call in a professional, this technical job requires some special knowledge and practical expertise. It’s a job that must be done properly to guarantee a fully functioning, trouble-free roof.

To help you protect your building, our Montreal roofers explain when and how to repair an asphalt shingle roof!

What are the signs that asphalt shingles need repair?

Identifying signs of wear and tear is the only way to decide when to replace or repair asphalt shingles. You may be surprised to learn that some types of damage demand urgent roof repairs.

Visible discolouration

Increased exposure to the sun, especially on south-facing homes, can lead to the shingle discolouration. This is a problem that mainly affects your home’s appearance, but it can also be a sign of more serious underlying problems.

As soon as you notice discolouration on asphalt shingles, take a closer look or hire professionals to examine or renovate your pitched roof.

Broken or lifted shingles

Broken or lifted asphalt shingles are another sign of wear and tear that shouldn’t be taken lightly. These can be signs of a faulty roof coating, improper installation, or overheating caused by insulation or ventilation issues. In winter, broken or lifted asphalt shingles can lead to seepage and other problems.

Granule loss is not as severe as breakage, but it is another sign of aging. If asphalt shingles warp, there is likely a problem with the substrate beneath them. If the base is made of wood, it’s possible that humidity has caused swelling or contraction. This is not the same as uplift and needs your urgent attention!

Missing shingles

If sections of asphalt shingles are missing, it’s usually because they’ve been torn off by wind or other severe weather. Roof maintenance or snow removal can also result in torn shingles, especially if you use the wrong tools or techniques.

Missing nails or glue can also lead to lost shingles. Whatever the cause, missing roof parts need to be replaced immediately to prevent larger problems that could affect the entire building. If you wait and the condition of your roof worsens, you may have to replace the entire asphalt shingle system.

While wear and tear on asphalt shingles is unavoidable over time, some shingles are more durable than others. Keep this in mind when making a purchase.

Moss and moisture

Often the only visible evidence of moisture on roofs is moss on the rooftop or mold in the attic. Black or brownish stains can also indicate that roof moisture has spread to the cladding. A simple way to protect your building is to clean your asphalt shingle roof regularly.

If the moisture problem spreads to the entire structure, a complete re-roof may be necessary. Before proceeding, get a professional roof inspection. It takes an experienced professional to give you appropriate advice.

Preparing for asphalt shingle roof repairs

Before you begin repairing your asphalt shingle roof, you will need to get ready. There are a few important points to consider.

Tools and materials

Make sure you have all the necessary tools and materials at hand before starting the repair.

• Claw hammer: for removing nails and damaged shingles
• Utility knife: to cut and remove damaged shingles
• New asphalt shingles: replacement shingles that match those already on your roof
• Roofing nails: to secure new shingles in place
• Wire stripping pliers: to remove damaged shingles
• Roof mastic: to seal shingles and make the roof watertight
• Secure ladder or scaffolding: for safe access to your roof
• Work gloves and goggles: to protect you during the repairs

With all necessary tools and materials ready, you’ll avoid unnecessary trips back and forth, and you can devote your full concentration to your roof repairs.

Safety precautions

Safety should be a top priority when repairing your asphalt shingle roof. Make sure to verify the security of the site and equipment before climbing on your roof! Here are some essential precautions:

• Use a strong, safe ladder, and verify that it is stable before climbing onto your roof.
• Wear non-slip shoes to avoid slipping on shingles.
• If possible, work in pairs. Having someone else on site can make the process safer and more efficient.
• Avoid working on your roof in windy, slippery or rainy conditions.
• Make sure the area around your ladder is clear of people and debris while you’re working.
• If you’re not comfortable with working at height, consider calling in a professional to do the repairs for you.

By taking these safety precautions, you can minimize the risks involved in repairing your roof, and work with peace of mind.

How to repair asphalt shingles

Let’s get down to the nitty-gritty of repairing an asphalt shingle roof. There are six key steps in the process:

Step 1: Clean the affected area

Before beginning repairs, clean the damaged area of your roof thoroughly. Remove any debris, dirt or residue that could get in the way. Use a stiff brush or broom to remove leaves, branches or other foreign matter.

Step 2: Remove damaged shingles

Use a claw hammer to remove all nails, being careful not to damage adjacent shingles. Use a utility knife to dislodge and remove the damaged shingles.

Step 3: Prepare the surface

Before installing new shingles, you have to prepare the raw surface. If your roof’s underlayment is damaged, now is the time to replace it. Make sure the surface is clean, dry and smooth. If necessary, remove any adhesive or mastic residue.

Step 4: Install new shingles

Now it’s time to install the new asphalt shingles. Start by aligning the first shingle and nailing it down. Continue with other shingles, following the manufacturer’s guidelines for overlap, making sure as you go that your asphalt shingles are always in line and spaced equally.

Step 5: Securing and sealing shingles

Use roofing nails to secure your new asphalt shingles. Make sure you drive them in deep enough to anchor them securely to the surface. Next, apply roofing adhesive or mastic to the edges of the shingles to seal them. Proper sealing helps prevent water infiltration and makes your roof more durable.

Step 6: Final inspection and site clean-up

Once the repair is complete, take the time to inspect your work. Check that your asphalt shingles are properly attached, aligned and sealed. Make sure there are no damaged or missing shingles left to replace. Collect all debris and waste from the repair and make sure you leave the area clean and safe.

Caution: Never attempt to install new asphalt shingles on top of the existing shingles. If you want your roof to be watertight, shingles must be installed on a flat, even surface. 

Preventing future damage to asphalt shingles

Once you’ve repaired your asphalt shingle roof, there are a few things you can do to prevent further damage:

• Regular roof maintenance: Schedule periodic roof inspections to detect any early signs of damage or wear. By spotting problems at an early stage, you’ll be able to treat them quickly and prevent them from getting worse.
• Debris removal: Clean your roof regularly. Leaves, branches and other debris can trap moisture and cause shingles to deteriorate.
• Moss and fungus control: Keep an eye on your roof, and if you spot moss, lichen or fungus, use specialized products or call in a professional to eliminate them safely.
• Manage water build-up: Check that your rain gutters and drainage systems are in good working order. Water build-up can lead to infiltration and damage, so clean your eavestroughs regularly to make sure they are properly draining water away from your roof.
• UV protection: Apply a protective coating or use asphalt shingles with UV protection to minimize the degradation caused by UV rays.
• Tree pruning: Prune nearby trees regularly to prevent branches from rubbing against shingles during turbulent weather.

With regular maintenance and vigilance, you can extend the lifespan of your roof and minimize the risk of future damage.

When it comes to choosing the best asphalt shingles for your roof, you should look for a durable, long-lasting and aesthetically pleasing product. Quality asphalt shingles are especially important in Quebec’s harsh climate, and choosing shingles wisely involves several factors.

Every property has its own specific needs, and if you consult a roofing professional, you can benefit from personalized recommendations.

In this article, our Montreal roofers present the main factors involved in choosing the best asphalt shingles, while introducing you to the trusted brands available in Quebec.

Types of Shingles

The asphalt shingles available in Quebec each offer different levels of durability, resistance and aesthetic appeal. Here are some of the most common types of asphalt shingle.

Fiberglass shingles

Fiberglass shingles are reinforced with a fiberglass mat, making them lightweight, durable and weather-resistant. Manufacturing fiberglass shingles requires less asphalt than organic shingles, making them much lighter and less expensive to create. They are often coated with mineral-fortified asphalt and coated with a layer of pigmented ceramic granules for additional UV protection. Fiberglass shingles come in a wide variety of colors and styles to suit different architectural designs.

Organic shingles

Organic shingles are reinforced with natural raw materials like cellulose. They are heavier than fiberglass shingles and offer excellent resistance to wind gusts due to their weight. The manufacturing cost of these shingles is higher, given the quantity of asphalt required to produce them. Organic shingles are also much more sensitive to temperature variations than fiberglass shingles, making them more prone to lifting and premature wear. However, fiberglass shingles offer better durability, making them a more popular choice.

Laminated shingles

Laminated shingles are layered asphalt shingles that mimic the appearance of traditional wood shingles while offering the benefits of asphalt. These shingles offer classic aesthetics and superior durability. Be sure to consider the quality of the lamination when you are choosing which shingles to use, as some manufacturers use more efficient laminating techniques than others.

Architectural (dimensional) shingles

Architectural or dimensional shingles are designed to mimic the appearance of high-end roofing materials like slate or wood. Their three-dimensional shape gives them a thicker, more textured appearance, offering an elegant, sophisticated aesthetic in addition to the durability and ease of installation of asphalt.

Each type of asphalt shingle has its own advantages and limitations. We recommend that you consult a roofing professional to determine the type of asphalt shingle best suited to your project.

Factors for choosing quality asphalt shingles

Choosing the right asphalt shingles for your roof involves carefully considering several factors, including durability, style and the length of the product warranty.

1. Durability and resistance

Asphalt shingles need to be durable and able to resist a variety of threats to effectively protect your roof for a long time.

Weather resistance

Asphalt shingles should be able to withstand strong winds, heavy precipitation (both rain and snow), and both high and low temperatures. Make sure the shingles you choose are specifically designed to withstand the challenges of Quebec’s climate.

Fire-resistance rating

The fire resistance of your roof is important for the safety of your entire home. Asphalt shingles are available with different fire-resistance ratings, and you should always choose shingles with the highest possible fire resistance.

UV resistance

Asphalt shingles can prematurely degrade due to ultraviolet (UV) rays from the sun. Check whether the shingles you’re considering include UV protection, as this feature will extend the lifespan of your roof.

2. Aesthetics and style

The look and style of your asphalt shingles will affect the overall appearance of your roof and building. Consider the following:

Color and texture

Asphalt shingles are available in a wide range of colors to suit different architectural styles and personal preferences. Whether you prefer neutral hues, bright tones or textured finishes, it’s possible to choose shingles that match your building. Consider the color of the facade and the surrounding environment when making your choice.

Harmony with the architectural style of the building

Whether your structure has a traditional, contemporary or modern design, choose shingles that complement and enhance the overall look of the structure. Manufacturers often offer specific collections of asphalt shingles designed to match different architectural styles.

3. Ease of installation

Consider how easy it will be to install asphalt shingles. This is especially important if you plan to shingle your pitched roof yourself.

Shingle size and weight

Asphalt shingles come in different sizes and formats. Some are easier to handle and install than others. If you’re new to asphalt shingle installation, we recommend opting for standard-size shingles. Also, check the shingle weight – lighter claddings can be easier to transport and install.

Installation system

Some manufacturers offer product-specific installation and assembly systems. These may include installation guides, detailed instructions and complementary accessories. When choosing your asphalt shingles, ask if there is an installation system available.

4. Warranty

The warranty is an important factor to consider when choosing asphalt shingles. It is reassuring to know that the product is backed by the manufacturer in the event of problems or defects. Here are two things to keep in mind:

Warranty period

Look for asphalt shingles with extended warranties, as this shows manufacturer confidence. Some brands offer warranties of up to 50 years or more, providing long-term protection.

To qualify for this type of warranty, installation must be carried out by a certified and recognized roofer.

Coverage of manufacturing defects

Be sure to read warranty terms and conditions carefully to verify whether they include protection against defective shingles, sealing problems, premature delamination, etc. Remember to check whether the warranty covers the costs of labour and repairs.

A good warranty should protect both your roof and your investment.

If you’re investing in a new roof in Quebec, Canada, you probably want to know how long it will last. The roof is one of the most important structural elements of a home, and it has to be capable of withstanding all the elements, from high winds to snow and hail.

The lifespan of a roof depends on several factors, including the type of roofing material, the installation quality, the level of exposure to the elements, and local weather conditions.

Our Montreal roofers take a closer look at the potential lifespan of both pitched (sloped) and flat roofs in Quebec. We also offer tips on how to extend the lifespan of your roof and avoid costly repairs.

Typical roof lifespan

The lifespan of a roof depends on many things, including the type of roofing materials you choose, how often you maintain your roof, the type of weather it is exposed to, etc. In general, a well-maintained roof can last anywhere from 15 to 50 years, and in some cases even longer.

Asphalt shingle roofs, the most common for residential homes, generally last 15 to 25 years. Metal roofs, on the other hand, can last up to 50 years or more, while tile roofs can have a lifespan of up to 100 years.

Generalizations aside, the actual lifespan of a roof is affected by external factors. For example, if your region experiences extreme weather conditions (as in Quebec), your roof may deteriorate more quickly. Similarly, poor installation or lack of regular maintenance can noticeably shorten the lifespan of your roof.

It is important to monitor the condition of your roof and schedule a professional inspection every few years, to confirm it is in good condition and detect any signs of damage or wear. This way, you can extend the life of your roof and avoid the high cost of premature roof replacement.

Lifespan of a flat roof

The durability of a flat roof depends on several factors, including the type of membrane you choose to install.

It is important to know what your options are so that you can choose the right membrane for your specific situation.

Multi-layer asphalt and gravel membrane

Flat roofs equipped with a multilayer asphalt and gravel membrane tend to deteriorate after prolonged exposure to the sun. UV radiation causes the asphalt to lose its oils and form cracks, compromising the flat roof’s membrane system. This is a bigger risk for roofs where the gravel has moved and is no longer shielding the asphalt against the sun.

If neglected, a multi-layer asphalt membrane will need to be replaced every 10 to 15 years. However, if you make sure that the gravel stays in place, provide proper drainage and promptly repair any cracks in the membrane, it could last for 15 to 20 years.

Elastomeric bitumen membrane

Installing an elastomeric bitumen membrane on a flat roof costs more, but the expense is justified by this product’s long life and easy maintenance. As an added bonus, white membranes have a solar reflectivity index (SRI) that contributes to increased comfort and lower air conditioning costs during hotter months.

The average life of an elastomeric bitumen membrane is 20 to 25 years. If yours is installed by a professional and maintained every two years, it can easily last over 30 years, especially if your roof system components are optimal.

Single-layer EPDM and TPO membranes

EPDM and TPO single ply membranes are environmentally friendly flat roof coatings that are well-suited to large roofs. They do not require much maintenance, but they do need to be monitored if exposed to hot sun, as is common in Quebec, to make sure they remain watertight.

Many homeowners opt for this type of membrane because it is not expensive. Under optimal conditions, these membranes can remain functional for more than 20 years.

Lifetime of a pitched roof

Pitched, or ‘sloped’ roofs are the most common type of roof on residential homes. They are often constructed using asphalt or wood shingles, or clay or concrete tiles. Their lifespan varies depending on the type of material, and the quality of installation and maintenance.

Asphalt shingles

Asphalt shingles are the most common for sloped roofs and last an average of 20 to 30 years. Some manufacturers offer a warranty of up to 50 years. Proper installation and regular maintenance can significantly extend the useful life of asphalt shingles.

Clay or concrete roof tiles

Clay or concrete tiles are more expensive than asphalt shingles, but they also last longer. Clay tiles can last from 50 to 100 years, while concrete tiles can last up to 50 years.

Tiles are not suitable for all types of buildings as they are heavy and not 100% waterproof. Contact a professional roofer to help you choose the right roofing material!

Cedar shingles

Cedar shingles are a more expensive option, but they offer a unique aesthetic. They usually last about 50 years, but regular maintenance, such as using anti-moss treatments and repairing cracks, can make them last longer.

In general, pitched roofs require regular maintenance to make them last as long as possible. This means regularly inspecting shingles, cleaning rain troughs and replacing damaged or missing shingles.

Metal roofing

Metal roofs generally last longer than other types of roofs – from 30 to 50 years. However, several factors can influence this, including environmental conditions and the quality of both installation and maintenance.

When to renovate your roof

Knowing how long your roof should last is one thing. You’ll still need to know exactly when to replace your roof to avoid serious problems. In general, a roof should be renovated every 20 to 25 years, but the type of materials used and your maintenance schedule will affect this.

There are signs other than a roof’s age that indicate it should be replaced. If you notice water leaks or seepage into your home, missing or damaged tiles, blisters or cracks in the roof materials, roofing granules in the rain troughs, or your roof looks discolored or faded, it’s time to pay attention.

Remember that if you plan to sell your home, an aging roof can significantly reduce its value. Renovating your roof before putting it on the market will help you get the best price possible.

Preventive roof maintenance and repair

Regularly inspecting a roof membrane is one way to make sure it lasts as long as possible. You can verify the condition of the membrane by checking the state of the roof, the solidity of the structure, the waterproofing of the building, and the integrity of roofing materials and their resistance to bad weather. If anything is out of order, you can make repairs before your building is damaged by water infiltration. 

Periodic roof inspection is also the best way to find out whether your home is properly ventilated and insulated. This can significantly impact the lifespan of your roof, as is proven by the fact that these elements are included in manufacturers’ warranties. It is a fact that poor ventilation or insulation prematurely wears out roof membranes.
