Why inspect the attic of a pitched roof?
It is necessary to inspect the attic to spot the first signs of infiltration before the water spreads throughout the property.
When should the roof be inspected?
It is advised that the roof be inspected every three months. Furthermore, it is possible to carry out an inspection following any major precipitation.
What are the signs of a bad insulation?
When the attic is poorly insulated, you notice the formation of ice on the roof and icicles around the edges. The cost of electricity is higher for air conditioning and for heating. In addition, the temperature seems difficult to control and sometimes causes discomfort inside your home.
How to calculate the R-value of the insulation?
The insulation needs vary depending on the building system and the type of roof. You are advised to consult the description sheet to know the R-value of the insulation. In general, the higher the R-value, the greater the insulation.
What are the requirements for holding a LEED Certification?
The evaluation system Leadership in Energy and Environmental Design (LEED) promotes the construction of green buildings. For this accreditation, it is necessary to meet several criteria for the universal components, construction, type of roof, and energy savings. Please refer to the certification requirements: www.ecohabitation.com
Why ventilate the attic?
Ventilation helps to preserve the full integrity of the building and roof covering. The risks of excessive moisture and overheating in the attic are then reduced. By the same token, it ensures the perfect comfort level inside the home. Speak with an expert to get recommendations tailored to your type of roof.
Why temper the attic?
Ventilation must keep the attic as close as possible to the outside temperature. Otherwise, the heat losses will melt the ice and create water seepage and will spread into the building. Damage can be serious if it is not addressed by roofing specialists.
Why do manufacturers require that the attic is ventilated?
Manufacturers' warranties do not apply if ventilation is inadequate. The difference between the outside and attic temperatures causes overheating which prematurely ages the covering. So ventilation is a criterion to meet for protection in case of problems.
Does the outer covering have a direct connection to the waterproofing of the roof?
Yes, because the flashing sealings are under the covering and under the shingles. If they are inadequate, you need to remove the entire covering to replace them. Furthermore, the wall covering is an integral part of the building waterproofing. So it must be in good condition to maintain water resistance and protect the integrity of the building.
What should we know about roofing?
There are different categories of sheathing. Asphalt shingles are popular because they offer good value for the cost. Depending on the roof system, it may be preferable to select a specific covering to overcome problems. It is advisable to talk to a technical consultant regarding covering alternatives.
What are the different types of asphalt shingles?
A few years ago, three-tab shingles were the most popular on the market. Today, laminated fiberglass shingles, which are more resistant, are popular. Architectural shingles, with their unique designs, are available for all types of pitched roofs.
How does water seepage occur?
The main cause of water infiltration is the presence of ice under the covering. During a thaw, the ice melts and the water leaks into the attic and then the interior of the house. Infiltration may also come from the lining wear, missing shingles, poor insulation, poor structure, etc.
What are the main solutions to water infiltration?
Depending on the situation, our roofers can locally replace the affected sections. If the coating does not need to be changed in its entirety, it is possible to change it locally. It is also important to properly seal openings by changing the rubber sealants or coverings with products adapted to your type of roof. The snow and ice may need to be removed to prevent the increase of ice on the roof.
When should you inspect the roof system?
It is recommended to check the attic every three months and after a heavy rainfall or high winds. As soon as you spot an anomaly, please see our roofers for a solution adapted to your type of roof.
What equipment is needed to clear the snow from a sloping roof?
According to the type of pitched roof, it is recommended to use the sleigh-shovels, standard shovels, ice picks, and chain saws adapted to the specific needs of de-icing. Personal protective equipment, such as lifelines and safety harnesses, is required. If necessary, we can use a snow blower to release the snow.
Why is it necessary to shovel the roof?
When ice forms, dams are created and extend over the roof. De-icing becomes necessary to prevent water infiltration or the weakening of the structure. Ideally, when snow and ice exceed 12 inches, it should be cleared.
Why entrust snow removal for roofers?
A skilled workforce knows how to remove snow and ice from all types of roofs without damaging the cladding. The quality of work is superior and you are protected if a problem occurs.
