Ventilation is an integral part of any type of roof, not only because it is required by the National Building Code of Canada (section 9.19), but also for its many benefits. The importance of having adequate ventilation is essential to keep the building in good condition and extend the durability of the roofing. Consequently, in summer, an overheated roof overhang has a direct impact on the comfort felt in the establishment. On the other hand, in winter, the roof must remain relatively cold and remain dry to avoid condensation and ice accumulation which can lead to water infiltration. Finally, it is important to choose the type and number of fans needed to ensure a good air flow of your roof.
