Experts are warning that ice dams are forming on many buildings in the Rochester, New York area, posing a serious threat of leaks, mold, and other extensive property damage if left unchecked.

Why it matters

Ice dams can cause significant and costly damage to homes and businesses if not addressed promptly. They can lead to water intrusion, mold growth, and structural issues that require expensive repairs. This is a common problem in cold-weather regions like Rochester that see heavy snowfall.

The details

Ice dams occur when heat escapes through the roof, causing snow on the upper portion of the roof to melt. The melted snow then refreezes at the roof's edge, creating a dam that prevents proper drainage and allows water to back up under the shingles and into the home or building.

  • Ice dams have been forming on many Rochester-area roofs in recent weeks due to the area's cold temperatures and heavy snowfall.
