An ice dam is a ridge of ice that forms at the edge of a roof. The formation of an ice dam will prevent melting snow from properly draining. As this excess water backs up behind the dam, it can begin leaking through the roof leading to damage of walls, ceilings and insulation.
Ice dams form after there has been snow cover on your roof and develop from a combination of outside temperatures and heat lost through the roof. If too much heat is lost through the roof and allows the upper portion of the roof to be heated above freezing (warmer than 32° F), it’s possible an ice dam will form as the melted snow travels to the lower and colder portions of the roof and refreezes.
The most common cause of ice dam formation is heat loss from the home or building’s interior. By installing proper insulation in new homes or increasing the thickness of insulation in older homes, heat loss can be reduced and prevent the formation of ice dams.
