More than 35 years ago, the introduction of Grace Ice & Water Shield® pioneered the self-adhered roofing underlayment category. Since then, signature projects around the world have relied on this high-performing underlayment to protect them from the elements.
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.
