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.

What are the different types of asphalt shingles?
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.
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.
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.
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 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.
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.

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 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.
