Overview
Your best defense against winter
The WinterGuard™ 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.
How WinterGuard works
WinterGuard is a composite material of asphalt polymers, formed into a
rolled sheet. The asphalt provides the waterproofing. The polymers make the
asphalt elastic and sticky, all the way through the sheet. The result is an
amazing ability to both stretch and cling. This means that WinterGuard
doesn’t rip when stressed and seals around nails driven through it. It
sticks to a clean roof deck like glue. And it won’t dry out during the
warranted lifetime of an asphalt shingle system. The result is a waterproof
barrier beneath your shingle system, which pooled water and wind-driven rain
cannot penetrate.
New! WinterGuard™ HT
WinterGuard HT (high tack, high temperature) is specially formulated to
resist high roof temperatures under metal roofs. Also for use with shingles
and tile.

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. |
