The answer to 'gutters ice dams' is that ice dams in gutters are a common problem that can cause significant damage to your roof and home. Ice dams form when snow melts on the upper part of your roof, then refreezes in the gutters, creating a barrier that prevents water from draining properly. This can lead to water backing up under the shingles and leaking into your home, causing water damage, mold, and other issues.
The main causes of ice dams are poor insulation and ventilation in the attic, which allow heat to escape and melt the snow on the roof. Factors like the roof's pitch, the amount of sunlight it receives, and the outside temperature can also contribute to ice dam formation. Symptoms of ice dams include icicles hanging from the gutters, water stains on the walls or ceilings, and damaged or sagging gutters.
