3' x 66.7' Grace Ice & Water Shield Self-Adhered Roofing Underlayment - (200 Square Foot Per Roll)

GRACE ICE & WATER SHIELD self-adhered roofing underlayment is a premier membrane composed of two waterproofing materials—an aggressive rubberized asphalt adhesive backed by a layer of slip resistant coated high density cross laminated polyethylene film.

The rubberized asphalt surface is backed with a foldless release paper that protects its adhesive quality. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to the roof deck. The Ripcord embedded in the adhesive provides the applicator a “split release on demand” feature.

GRACE ICE & WATER SHIELD has protected the roofs of over 2 million homes, and been installed on marquee projects in 25 countries, since its introduction in 1978. This high performance solution provides superior performance at an excellent value.
