Grace ICe & Water Shield Installation Roofing Underlayments

GCP Applied Technologies has been the leader in roofing underlayments​ since 1978, when it introduced the first fully-adhered roofing underlayment, Grace Ice and Water Shield®. For more than 35 years, Grace Ice & Water Shield® has become  the most trusted brand that roofing contractors and architects use and specify on projects around the world.

Since the introduction of Grace Ice & Water Shied®, we have developed a comprehensive portfolio of roofing underlayment products to fit the specific desi​gn, climate, and application requirements of your clients’ roofs.

The GCP roofing underlayments portfolio provides a number of benefits that competing products cannot provide. Our self-adhered roofing underlayments are designed to provide strong adhesion to the roof deck, superior watertight laps, and the highest quality seal around roofing fasteners. Selecting GCP roofing underlayment products for re-roofing and new construction projects helps avoid leaks, costly damage and call-backs.

GCP--and our predecessor company, Grace--have been trusted by contractors when waterproofing homes for almost 50 years. GCP offers best in class, premium performance roofing underlayments for a variety of roofing projects – whether it be for shingle, slate, shake, metal, tile, copper or zinc ro​ofs.

Signature buildings around the world have used GCP underlayments, including the Pentagon (USA), The Guggenheim Museum (Spain), the Emirates Towers (UAE), and m​any others.  Roof It Right™ with roofing underlayments from GCP Applied Technologies.
