Ice dams are an accumulation of ice at the lower edge of a sloped roof. When interior heat melts the snow, water can run down and refreeze at the roof's edge, where it's much cooler. If the ice builds up and blocks water from draining off the roof, water is forced under the roof covering and into your attic or down the inside walls of your house.
To help reduce the risk of ice dams:
Make sure your gutters are clear of leaves and debris.
Keep the attic well-ventilated so snow doesn't melt and refreeze on the roof's edge.
Make sure the attic floor is well insulated to minimize the amount of heat rising through the attic from within the house.
