Winter Guard

Your best defense against winter. The WinterGuardT Series of waterproofing shingle underlayments are applied under roof shingles during new construction or re-roofing to protect your home’s interior from winter leaks caused by ice dams and wind-driven rain.

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.

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.
