Repair Ice Damming

If your house isn’t insulated correctly or your roof isn’t designed correctly, melting roof snow can run off and freeze around roof edges. Eventually, this can form an ice dam that creeps up your roof, damaging shingles and forcing melting water into your home.

One popular solution to ice damming is to install a heating cable along the roof’s edge, which warms the area and prevents freezing. It’s not a DIY job. Roofing contractors will install the cable, and an electrician will install outlets that will juice up the cable. If you want a thermostat to turn the cable on and off automatically, that’ll be extra, too.
