Owens Corning Titanium PSU30 High-Temp Self-Adhered Roof Underlayment 36 in x 72 ft, 216 sq ft

Owens Corning Titanium PSU30 High-Temp Self-Adhered Roof Underlayment is a professional-grade rubberized-asphalt underlayment engineered to provide superior protection beneath shingles, shakes, tile, or metal roofing. Each 36 in × 72 ft roll covers 216 sq ft and is designed with a patented Sure-Foot® nodular walking surface that resists slips and tears during installation. This durable rubberized-asphalt membrane lays flat and provides a slip-resistant walking surface to enhance safety and ease of use on the roof deck.

Because the underlayment is made from a modified rubberized asphalt, it does not absorb water or wrinkle like traditional felt. The material resists mold growth, ensuring a dry and stable roof deck. Titanium PSU30 is rated for high-temperature performance up to 240 °F (115 °C), offering excellent durability even during heavy roof traffic and harsh weather conditions.

Titanium PSU30 is lightweight, with a nominal weight of 51 lbs per roll, and can be easily handled by roofing crews. Its advanced Sure-Foot® non-slip surface and 180 days of UV exposure resistance allow for faster, wrinkle-free installation and longer-lasting protection for the roof deck until the primary roofing material is applied.
