How do I prevent ice dams on my roof?

By Bob Millaway, South Jersey Community Expert & REALTOR®

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.
