Step up to superior roofing underlayment performance with Epilay EpiStik Plus, a premium heavy-duty self-adhered synthetic product engineered to meet the demanding requirements of commercial and high-end residential roofing projects. Replacing traditional asphalt-based peel and stick underlayments, EpiStik Plus features a unique and extremely strong 5-ply construction, combining coated woven polypropylene with an additional layer of non-woven polypropylene and a robust layer of SBS modified bitumen adhesive. This advanced adhesive provides exceptional adhesion to both plywood and metal decks across a wide temperature range of -40°F to 260°F, ensuring reliable performance in diverse climates without drying out, cracking, or leaching oil.

The 48 mil thickness provides a substantial barrier offering excellent Ice Dam Protection. The light grey GripWalk™ high-traction top surface provides a cooler working surface and enhances walk-ability and safety on sloped roofs, even when wet. Installation is made easier with a split release liner featuring silicone coating on both sides and excellent rollability. EpiStik Plus is water repellent, non-absorbent, UV resistant for up to 180 days, and completely impervious to mold growth due to its synthetic composition. It offers excellent nail sealability, further contributing to a watertight system, and holds a Class A Fire Rating (ASTM E 108). This versatile underlayment is ideal for use under metal, shake, concrete tiles, slates, and asphalt shingles. Available in convenient 2-square rolls weighing 48 lbs (3ft x 66.7ft), EpiStik Plus is a durable, strong, 100% recyclable, and Florida Building Code approved solution, backed by a Limited Lifetime warranty.
