Protect your roofing system from the damaging effects of ice dams and water infiltration with Epilay EpiStik Ice & Water Self-Adhered Roofing Underlayment. This top-of-the-line, heavy-duty underlayment is a granulated fiberglass-reinforced SBS modified bitumen membrane specifically formulated for critical Ice Dam Protection and overall waterproofing on sloped roofs. It serves as a premium replacement for traditional peel and stick underlayments in applications where ice and water protection is paramount.

EpiStik Ice & Water is engineered for high-temperature performance, with a temperature range of -40°F to 250°F, ensuring reliable adhesion and flexibility in diverse climates. The SBS modified bitumen adhesive provides excellent adhesion to the roof deck and will not dry out or leach oil in high heat, or become stiff and crack in colder temperatures. The substantial 55 mil thickness offers a robust barrier against water. Featuring a unique 3″ Overlap Edge, it ensures excellent adhesion and a watertight seal at all laps, contributing to a fully sealed system. This underlayment is water repellent, non-absorbent, and UV resistant for up to 90 days. It also holds a Class A Fire Rating as per ASTM E 108, adding an important layer of safety. With excellent rollability and a composition that resists wrinkling and cracking, installation is smooth and efficient. EpiStik Ice & Water is ideal for use under a wide variety of primary roofing materials, including asphalt shingles, tiles (concrete and clay), shakes, and metal roofing. Importantly, it is Florida Building Code and Miami Dade Approved, meeting the rigorous standards required for high-velocity hurricane zones and providing essential protection against wind-driven rain and ice damming. Backed by a Limited Lifetime limited warranty, it’s a durable and reliable choice for long-term performance.
