Asphalt shingles ice dam

Roofing

The answer to 'asphalt shingles ice dam' is that ice dams can form on asphalt shingle roofs, causing water to back up and potentially leak into the home. This is a common problem in cold climates during the winter months. Ice dams form when heat escapes from the home, causing snow on the roof to melt and then refreeze at the roof's edge, creating a dam that traps water.

Symptoms of an ice dam include icicles forming along the roof's edge, water stains or damage on interior walls and ceilings, and ice buildup on the roof. Solutions include improving attic insulation and ventilation to prevent heat loss, clearing snow from the roof, and using de-icing cables or heat tape to melt the ice dam. In severe cases, it's best to call a professional roofing contractor to safely remove the ice dam and inspect for any resulting damage.
