What Is Ice Damming and How Do I Prevent It?

What Is Ice Damming and How Do I Prevent It?Ice damming is the result of a continuous cycle where snow on your roof is melted by the sun or heat from inside your home escaping, possibly due to inadequate attic insulation and/or roof ventilation. The ice dam occurs when water runs down to the roof edge where it refreezes, then continues to build up higher until it eventually backs up under your roof shingles. Ice dams can be very dangerous and costly. Plus, some damage may not be easily seen, sometimes for years.

When the outside temperature warms up, the ice buildup will begin to melt. Since the ice buildup has worked its way up under the shingles, the water from the ice melting can work its way into your home, damaging the attic walls, floors, furniture, and eventually your basement. If the ice dam breaks free, it can pull shingles and gutters off with it, and it will damage anything it falls on: shrubs, cars, and people.

Proper roof ventilation and adequate attic insulation are vital to maintaining your home and reducing ice damming. Homeowners can also reduce ice dams by raking the roof with a snow rake to expose the shingles at the eaves. A good rule of thumb is to clear off your roof after every 4-6 inches of snowfall. Snow raking will also lessen the weight on your roof, which will ease stress on the structure and reduce any leaks or weak points.
