GRACE: Ice & Water Shield
Premium performance underlayment, protecting roofs since 1978.
For architects and roofing contractors, roofs are a source of everlasting concern. Seventy percent of all construction litigation is related to leaks, and every leak is a lost opportunity, representing a cost to repair and a corresponding loss of customer trust. Severe weather seems to be the new normal and the risk of damage from ice dams and wind-driven rain are higher than ever. Underlayments are the last line of defense in a roofing system, and selection of high quality underlayments can be the difference between success and failure.
Protecting 2 Million Roofs in 25 Countries
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. GRACE ICE & WATER SHIELD® outperforms the competition, letting contractors shine and keeping families safe and dry.
Better for homeowners
GRACE ICE & WATER SHIELD® protects a homeowner’s roof from the damaging effects of water intrusion due to wind-driven rain and ice dams because it:
- Fully adhered roofing underlayment sticks aggressively to deck surface
- Forms a watertight seal around fasteners used to install shingles and other roof coverings
- Forms watertight seal at overlaps
- Protects all standard sloped roofs–slate, tile, shakes or metal, as well as ordinary asphalt shingles
GRACE ICE & WATER SHIELD® is designed to perform for the life of the roof covering.
Featured Grace Products
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® is a versatile underlayment material that may be used on sloped roofs, under mechanically attached roof coverings such as asphalt shingles, slate, tile, cedar, and standing seam metal in many climate and assembly conditions.
