Hybrid Waterproof Roofing Underlayment for Asphalt Shingles and Metal Roofs
Hybrid waterproof roofing underlayment is an 8-layer laminated roofing underlayment that combines asphalt, synthetic fabric, non-woven reinforcement and HDPE film. It acts as a vital secondary water barrier under shingles or metal roofing, helping protect the roof deck and building structure from wind-driven rain, snow and ice.
- Strong and leak-resistant: Passed 110 mph wind test and 4-hour water spray test with cap and roofing nails, providing reliable protection under severe weather.
- High tensile strength & tear resistance: Engineered with reinforced fibers to deliver excellent strength in both machine and cross directions, reducing the risk of tearing during installation.
- Wrinkle-free & walkable surface: Lays flat and stays flat, with a textured, anti-skid surface to offer a safer walking surface for roofers.
- Lightweight & efficient coverage: Hybrid construction keeps weight low while offering over 450 sq.ft coverage per roll, making it easier to carry, handle and install.
- High temperature & UV resistance: Designed to withstand high roof temperatures (up to 260 °F) and short-term UV exposure, suitable as a temporary dry-in layer during construction.
- Meets ASTM standards: Complies with ASTM D1970 nail-sealing requirements for roofing underlayments, enhancing long-term watertight performance around fasteners.
