Mid-States ASTM D-226 30 Asphalt Saturated Roof Underlayment 36 in x 72 ft, 216 sq ft

Mid-States ASTM D-226 30 Asphalt Saturated Roof Underlayment is a professional-grade asphalt-saturated organic felt 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 high-strength, nonwoven surface that resists tears during installation. This durable construction is designed to lay flat and provides a slip-resistant walking surface to enhance safety and ease of use during installation.

Because the underlayment is made from high-quality asphalt-saturated material, it does not absorb water or wrinkle like traditional felt. The material resists mold growth, ensuring a dry and stable roof deck. ASTM D-226 30 is up to 2 times stronger than traditional #15 felt, offering excellent wind resistance and durability even during heavy roof traffic and harsh weather conditions.

ASTM D-226 30 is lightweight, with a nominal weight of 56 lbs per roll, and can be easily handled by roofing crews. Its advanced backside non-slip coating and 60 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.
