Factors to Consider for Choosing Roofing Material in Cold Climates
Slope and Design
The slope of a roof is significant during winter weather. Steeper slopes facilitate the easy sliding off of snow and ice, lowering the risk of ice dams forming along the edges. Ice dams can lead to leaks inside the home. For effective drainage, contractors should design roofs with a slope of at least 4:12. This allows snow runoff to occur quickly, protecting the roof structure from the weight of heavy snow and ice.
Insulation is also important; a well-insulated roof temperature reduces the likelihood of melting snow that can refreeze and generate more ice dams. Choosing durable roofing materials like slate or metal roofs can enhance energy efficiency and help manage snow buildup. Unlike cedar shake roofs or fiberglass asphalt shingles, these materials can better handle snow loading and high winds, reducing repair costs from storm damage.
Considering features like flashing and the right shape can result in roofs that last longer and are easier to maintain through harsh winter conditions, as nature can be challenging on homes.
