Canadian Roofs: How They Are Made Different

A few things distinguish Canadians from other countries, such as our obsession with hockey and our excessive use of the word "sorry". Roofs are one of these things. They aren't made from beaver fur or carved out from an igloo. However, there are some things Canadians should consider when it comes to roofing.

While there are exceptions (e.g., Victoria and Vancouver), Canada is generally cold. With cold weather comes unique challenges in the roofing industry, and special attention must be given to roof performance under winter conditions.

Roofs that are made for warmer climates and designed to accommodate people who live in them are common. These roofs can lead to condensation and mold problems. When searching for advice online, it is crucial that you use a resource that is local to your area.

Ice is another factor Canadian roofing companies must consider. An underlay, such as a dam or dam underlay, is required in order to allow for ice buildup. A waterproof membrane is used to protect roof areas from water damage and acts as an ice- and water protector. An ice and water protector should always be installed before other underlayments, and if installing around chimneys or other roof features, it should be placed below the flashing.



Proper attic ventilation is essential due to the additional water and ice protection Canadian roofs require. Proper ventilation will prevent moisture buildup in your attic and prevent condensation from occurring. Ideal attic ventilation should consist of 50% continuous soffit vents and 50% ridge, roof, or gable vents.
