Ice dams are ridges of ice that form along the edges of roofs, preventing water from draining properly. This can lead to leaks, water damage, and even structural damage to the home. To avoid ice dams, it is important to ensure that the roof is properly insulated and ventilated, and that gutters and downspouts are clear of debris.
Ice dams are most common in cold climates where there is a lot of snow and ice. When snow accumulates on a roof, it can melt and then refreeze at the edge of the roof, where it is colder. This process can create an ice dam that blocks the flow of water from the roof. As more water accumulates behind the ice dam, it can eventually leak into the home.
