GCP is a leading global provider of construction products technologies that includes GRACE ICE & WATER SHIELD®, the original self-adhered roofing underlayment, additives for cement and concrete, the VERIFI® in-transit concrete management system, high-performance waterproofing products and specialty systems. GCP products have been used to build some of the world’s most renowned structures.

GCP’s flagship product, GRACE ICE & WATER SHIELD®, the original self-adhered roofing underlayment, protects roofs from extreme weather such as wind-driven rain and ice dams.

The GRACE ICE & WATER SHIELD® underlayment seals around the fasteners used to attach the shingles, which helps prevent water buildup from leaking into the house. This premier underlayment also sticks to the roof deck to keep water from traveling under the underlayment and entering the house via a vulnerable roof deck joint.

For over 40 years, contractors have relied on GRACE ICE & WATER SHIELD®, fully-adhered roofing underlayment from GCP to provide quality protection. GRACE ICE & WATER SHIELD®, self-adhered roofing underlayment provides premium performance as it seals to itself at overlaps, seals to the roof deck and, most importantly, seals around the fasteners used to attach the shingles, which helps prevent water from leaking into your home. In the event roof coverings are blown off or water manages to get underneath your shingles, these underlayments are the key to preventing water infiltration.
