Ice dams are a common problem in the winter months, causing damage to roofs and other structures. Fortunately, there are a few steps you can take to help prevent ice dam damage.

What Are Ice Dams?

An ice dam is a ridge of ice that forms along the edge of a roof, typically in cold climates where snow accumulates. As the warm air from inside your home rises and melts the snow on your roof, the melted water runs down the roof, refreezes at the edge, and forms a dam. This dam can cause water to back up under your shingles and into your home, resulting in costly damage.
