If you have ice dams or icicles forming on the eaves of your home, using a heat trace to melt it won't fix the underlying issue: too much heat is escaping your home, melting the snow on your roof, causing water to run down to your eave, where it refreezes as ice. Whew!
The solution to ice dams is to reduce your home's heat loss:
- Air seal above your ceiling (like light fixtures and exhaust fans)
- Insulate (take advantage of Chelan PUD rebates)
- Ventilate your attic (using ridge and soffit vents)
Not only will these steps stop ice dams and home damage, they'll also keep you more comfortable and lower your heating bills.
