As winter weather continues in Minnesota and Wisconsin, we can expect more cold temperatures and icy precipitation. The heavy snows and uneven temperatures can cause ice dams on your roof. Unfortunately, ice dams can cause damage to your roof, shingles, gutter system, attic insulation, and drywall. If they are left untreated, ice dams can even cause mold and mildew growth. In this blog, we’ll look at how ice dams form, the damage they can cause, and how you can prevent them.
How Ice Dams Form
Ice dams are caused by accumulated snow and uneven temperatures on a roof. During the winter, the upper area of a roof is warmer than the lower edge. The snow then begins to melt and run down the slope. Once it reaches the colder lower edge, it refreezes and creates a block of ice called an ice dam. An ice dam prevents snow from melting and draining. It causes water to pool on the roof which can eventually back up under your shingles or cause damage to your roofing system and home’s interior.
How Ice Dams Affect a Roof
Once an ice dam has formed, it can cause significant damage to your home if it is not removed. As a whole, ice dams can cause damage to your roof, shingles, gutter system, attic insulation, and drywall. If unknown and left untreated, they can even cause problems within your home including uneven floors and rotten wood. If they do not dry out properly, it can lead to the right conditions to cause mildew and mold.
How to Prevent Ice Dams
You can prevent ice dams with proper winter maintenance, snow removal, proper attic ventilation, and insulation. Before winter arrives, have your roof properly inspected by a professional roofing contractor. They can tell you what maintenance needs to be done and provide specific recommendations to help you prevent ice dam damage to your home.
