When comparing roofing materials for British Columbia’s climate, metal roofing is significantly more durable than asphalt shingles against heavy snow and wind.
According to the provided data, metal roofing offers several specific advantages for harsh weather:
- Snow Resistance: Metal roofs have an excellent resistance rating and a slick profile that allows snow to shed easily. This prevents the formation of ice dams, which is a critical advantage during heavy, wet snow cycles.
- Impact Rating: Metal roofing carries a Class 4 impact rating, providing superior protection against physical stress.
- Wind Resistance: While asphalt shingles are considered "good," they are prone to wind uplift during severe storms. In contrast, metal roofing is noted for its secure fastening and structural strength to withstand corrosive coastal winds and high-pressure systems.
- Longevity: Due to its durability, metal roofing has an average lifespan of 40–70 years, whereas asphalt shingles typically last only 15–25 years in the BC region.
