Ice Dams

Publication Type:

Published / Updated:

A major solution to ice dams is properly sealing attic bypasses. In most cases ice dams begin inside the home when heated air leaks up into the unheated attic. This air warms part of the exterior roof, melting snow. This snow then runs down the roof slope until it refreezes, forming ice along the eaves, forming an ice dam. This ice dam can push the water under the shingles and even penetrate your home's ceiling and walls. By sealing attic bypasses, you can prevent ice dams from forming and make your home more energy efficient. Download this guide for an illustrated explanation of causes and prevention of ice dams.
