Icicles may be pretty, but when they form as ice dams it can mean structural damage and other costly problems for your home. One or two inches of snow accumulation, coupled with sub-freezing and above freezing temperatures, is all it takes for these harmful ridges of ice to build up on roof eaves.
WHAT CAUSES ICE DAMS?
Snow accumulates on the roof
Heat escaping through the attic melts the snow
The cold air refreezes the melted snow into solid ice
WHAT IT MEANS FOR YOUR HOME
As ice dams take shape, heat from inside the house travels though the attic, warms the roof and melts the snow outside. The melting snow runs down the roof until it reaches the cold roof edge where it refreezes. Ice dams can then force water to back up under the shingles and into the ceiling or walls of the house. If left untreated, this can lead to warped windows, buckling floors, and collapsing drywall or plaster.
The best way to prevent ice dams is to stop them from forming in the first place, and to do that you need to identify where your home is leaking air and letting heat escape.
