About Ice Dams:

On a smaller scale, icedams are a problem of house and building maintenance in cold climates. An icedam can occur when snow accumulates on the slanted roof of a house with inadequate insulation and ventilation in the attic. Warmth coming up through the roof melts the snow. Meltwater flows down the roof, under the blanket of snow, onto the eave and into the gutter, where colder conditions on the overhang cause it to freeze. Eventually, ice accumulates along the eave and in the gutter. Snow that melts later cannot drain properly through the ice on the eave and in the gutter.

Say goodbye to icedams Throw a handful on your roof and melt a channel for water to drain.
