Lock out damage from ice damming and wind driven rain
WeatherLock Series is the Owens Corning self-adhesive waterproofing underlayment that
is perfect for both new construction and reroofing applications on sloped residential
buildings with wood decks.
It is available in two surfaces: Polyethylene (our premium-grade) and granule surface
(GS - our affordable-grade).
The unique composition of a polyethylene or granulated surface, Styrene Butadiene Styrene (SBS) modified asphalt and a fiber glass mat helps lock out damage from ice damming and
wind-driven rain. And it's backed by a five-year limited warranty.*
WeatherLock, installed between the roof deck and asphalt shingles, cedar shakes, concrete tile or metal roofing, lays flat and remains dimensionally stable.
Rain. Shine. Or Ice.
