In the coming week, the forecast for Southeast Michigan calls for precipitation on several days while low temperatures hover around the freezing mark. Icing on streets, sidewalks and parking lots is inevitable. But there is one type of ice that these conditions can lead to that is especially problematic for a homeowner. That’s the development of ice dams on the roof.
If you’ve spent at least one winter in Michigan, you’ve seen ice formations on roofs in your neighborhood. They look spectacular at times, yet they can lead to unwelcome results. As melted snow flows down from the rooftop and gets blocked by snow along the eaves, it can freeze at the roof’s edge and form a band of ice. This ice dam prevents additional melted snow from flowing properly off the roof and into a gutter system. Instead, the backup can trigger a leak in the roof or roof trim.
One immediate response to ice dams seems to be using a variety of tools to break up the ice formations. This can be a risky choice though for a couple of reasons. Wielding an ice pick, a hammer, or a crowbar can be a personal safety issue when it’s chilly and slippery outside. Also, using blunt force to break the ice can lead to roof damage, including tears or punctures in shingles.
Rather than put yourself and your roof at risk, here are three things to consider that can reduce the threat of ice dams.
1. Install proper insulation in key areas. About 12 inches of fiberglass or cellulose ceiling insulation is recommended in climates like this one. Use insulating foam above the exterior wall and seal it for prevent the leakage of warm air.
2. Create proper roof ventilation. An effective ventilation system lets outside air flow through the attic, balancing air intake and air exhaust, and keeping the insulation working efficiently. The Federal Housing Administration recommends at least one square foot of ventilation for intake and exhaust for every 300 square feet of attic space.
3. Invest in a metal roof. The slippery surface and steep pitch can help a roof shed snow more easily.
