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.
