Ice Dams and Cold Roofs

Why Ice Dams Form

Ice dams along the eaves are a common winter problem in Minneapolis. When warm air escapes into the attic, it melts snow on the roof, which refreezes at the cold edge and backs water up under the shingles. Poor attic insulation and air sealing are the root cause.

Spray foam seals and insulates the attic so the roof stays cold and ice dams stop forming.

A professional applies closed-cell spray foam to the roofline, stopping the warm-air leak that drives ice dam formation.
