How do I prevent ice dams on my roof?

Ice dams form when heat escapes through your attic and melts snow on the roof, which refreezes at the eaves. Prevent them by ensuring your attic is well-insulated, sealing air leaks, and keeping your attic cold. Remove snow from the roof edge with a roof rake after heavy snowfall.

Why It Matters

Ice dams can cause water to back up under your shingles, leading to roof leaks, damaged gutters, and interior water damage.
