The answer to 'roof repair ice dam' is that ice dams are a common problem that can cause significant damage to your roof and home. Ice dams form when snow and ice melt on the upper part of your roof and then refreeze at the edge, creating a barrier that prevents proper drainage. This can lead to water backing up under the shingles and leaking into your home, causing water damage, mold, and other issues.
The most common causes of ice dams are poor insulation, inadequate ventilation in the attic, and heat loss from the home. Symptoms of ice dams include icicles forming along the roof's edge, water stains on the ceiling or walls, and water pooling on the roof. To fix the problem, you may need to remove the ice dam, improve insulation and ventilation, and potentially make structural changes to your roof or home.
