The answer to 'architectural shingles ice dams' is that ice dams are a common problem that can occur with architectural shingles. Ice dams form when heat escapes from the home, causing snow on the roof to melt and refreeze at the roof's edge, creating a dam that prevents proper drainage. This can lead to water damage, leaks, and other issues.
Causes of ice dams with architectural shingles include poor attic insulation, inadequate ventilation, and heat loss from the home. Symptoms include icicles forming at the roof's edge, water stains on the interior walls or ceilings, and shingles lifting or curling. Solutions can include improving insulation, adding ventilation, and using de-icing cables or heat tape to melt the ice dam. In severe cases, it's best to call a professional roofer to assess the problem and recommend the appropriate solution.
