Problem
Ice dams — nasty build-ups of ice and snow — form from freeze-melt cycling on your home’s roof deck. When the ice and snow melt, trapped water can seep through the roof, damaging the roof deck, insulation and the interior of your home.

Solution
WinterGuard waterproofing shingle underlayment is installed between the roof deck and the shingles, creating a weather-tight barrier that prevents backed-up water from getting into your home.
