What Is Snow Load?

Snow load refers to the weight of snow sitting on your roof. In Ontario, this can become a serious concern during long winters, especially when snow becomes wet, heavy, and compacted.

Traditional asphalt shingles hold snow longer because of their rough surface. This allows weight to build up and places extra stress on your roof structure.

Metal roofing helps reduce this problem by allowing snow to shed more efficiently. This makes it a smart long-term option for Ontario homeowners who want better winter performance.

Why Metal Roofing Performs Better in Winter

Ice Dams and Freeze-Thaw Damage

Ice dams form when snow melts on the roof and refreezes near the edges. This can trap water behind the ice, creating leaks and damaging the roof system.

Freeze-thaw cycles also cause asphalt shingles to expand, contract, crack, and age faster. Over time, this leads to repairs, leaks, and premature replacement.

A properly installed metal roof helps reduce these risks by improving snow movement, resisting moisture, and maintaining long-term stability through winter conditions.
