How it works
Businesses listed here install heat cables and other ice dam prevention. Ask what else they do: many also seal and insulate attics, which is the work University of Minnesota Extension and the state energy office put first.
- Ask why the ice dams form on your roof before choosing a fix.
- Get a price for air sealing and insulation as well as for cables.
- If you choose cables, ask how they are fastened and what they cost to run each winter.
When to call
Call when ice dams return every winter and attic work is not possible right away, and ask for an attic assessment at the same time.
- Icicles or ice along the roof edge fixes cause
