Quick Answer
For areas with heavy snow accumulation, choose roofing materials with high snow load ratings and durability, such as metal, corrugated plastic, or rubber roofing options. Asphalt shingles are not recommended for areas with extreme snowfall due to their lower weight capacity. Look for materials with a minimum snow load rating of 30 pounds per square foot.
Roofing Materials with High Snow Load Ratings
When selecting a roofing material for areas with heavy snow accumulation, prioritize options that can withstand the weight of snow without compromising structural integrity. Metal roofing is an excellent choice, as it can support snow loads of up to 50 pounds per square foot. Look for metal roofing materials with a thickness of at least 24-gauge, which can withstand extreme weather conditions.
Installation Techniques for Snow-Resistant Roofing
To ensure a snow-resistant roofing system, proper installation is crucial. When installing metal roofing, use a minimum of 6 inches of clearance between the roof’s edge and any obstructions, such as trees or power lines. Additionally, ensure that the roof’s slope is at least 3:12 to prevent snow from accumulating and forming ice dams.
Alternative Roofing Options for Snowy Areas
For areas with extreme snowfall, consider alternative roofing options such as corrugated plastic or rubber roofing. These materials are lightweight, easy to install, and can support snow loads of up to 30 pounds per square foot. When selecting a corrugated plastic roofing material, choose one with a thickness of at least 0.019 inches to ensure durability and snow resistance.
