Ice dams can form when warm air leaks into the attic and heats up the space under the roof. As ice accumulates on the lower edge of a sloped roof the snow melts on the roof and drips; then it can re-freeze when it gets cold and builds up which puts pressure on the gutter system and roof shingles. The ice blocks water from draining off the roof causing it to settle under the roof shingles and leak inside the attic or down the interior walls of the house.
Before cold weather sets in take these steps to prevent ice dams from forming:
- Clean gutters and downspouts so they are free of leaves and debris and water can flow through them easily.
- Upgrade inadequate insulation in the attic to lower the amount of heat that rises through it.
- Improve ventilation so air flows freely in the attic.
