The answer to 'roof replacement ice dam' is that ice dams are a common problem that can lead to the need for roof replacement. 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 the need for costly roof repairs or replacement.
Some common causes of ice dams include poor attic insulation, inadequate ventilation, and an uneven roof surface. Symptoms may include icicles forming along the roof's edge, water stains on interior walls, and sagging or damaged gutters. Solutions can include improving insulation, adding ventilation, and ensuring proper roof drainage. In some cases, a full roof replacement may be necessary to address the underlying issues.
