Grace Ice & Water Shield®

Self-adhered roofing underlayments are designed to protect homes from wind-driven rain and ice dams. Grace Ice & Water Shield’s proprietary and time-tested rubberized asphalt formulation enables a watertight bond with the roof deck acting as a barrier for both water and ice. Grace Ice & Water Shield® has shown the ability to maintain a watertight seal around fasteners used to attach roof coverings. In addition, our ice and water barrier offers superior watertight laps, which are critically important in keeping the roof dry and safe. Grace Ice & Water Shield® also features the Ripcord® system, split release on demand, allowing for easy detailing of leak prone areas of the roof deck, such as valleys, chimneys and roof to wall transitions.

GCP Applied Technologies’ roofing underlayments can be used in new construction, re-roofing, or on roof repairs. For applications with high service temperatures, choose Grace Ice & Water Shield® HT. It has been specially formulated to meet the service temperature challenges inherent in metal roofing systems, and insulated roofing assemblies.

Grace Ice & Water Shield® is the name that contractors have trusted for over 35 years to protect their reputations and to provide peace of mind against costly call-backs.
