How an ice dam forms
Heat escaping into the attic warms the roof deck, snow melts and runs down to the cold eave, and the water refreezes into a ridge of ice. The next melt has nowhere to go, so it pools behind the ice and works under the shingles and into the ceiling.
- Wet insulation that no longer insulates.
- Stained or sagging ceilings under the eaves.
- Peeling paint and damp exterior walls.
- Dripping light fixtures that signal water above.
