Ice Dam, What's that?
Have you ever heard of an ice dam?
Ice dams can be a little-known, but major problem during the snowy season. They form when heated air melts roof snow downward into water dammed behind still-frozen ice. When the trapped water cannot safely flow or run into the gutter system, it can backflow under the roof ’s shingles and
into the structure’s interior areas, as well as causing gutters and shingles to move or fall.
So what causes ice dams?
They’re often caused from poor ventilation and climate control within the attic of a home. When the attic gets too warm, this can cause snow on the roof of the home to melt. When your home has recessed lighting, skylights, intricate roof designs and/or heating ducts, you’re probably at an increased chance for an ice dam to form.
How can you check for ice dams?
You can look for some warning signs that will tip you off to the presence of the elusive ice dam. Icicles can be an initial sign, according to Travelers.com. To spot ice dams inside, “check for water stains or moisture in your attic or along the ceiling of exterior walls of your house. Water stains or moisture may be an indication that an ice dam has formed and water has penetrated the roof membrane.” Another sign is if ice is coming through the home’s soffits or forming in the gutters, or there’s ice appearing on the exterior walls.
