APOC Gator-Skin Synthetic Roof Underlayment 42 in x 285.8 ft, 1000 sq ft

APOC Gator-Skin Synthetic Roof Underlayment is a professional-grade synthetic underlayment engineered to provide superior protection beneath shingles, shakes, tile, or metal roofing. Each 42 in × 285.8 ft roll covers 1000 sq ft and is designed with a high-strength, nonwoven surface that resists tears during installation. This synthetic 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 durable synthetic materials, it does not absorb water or wrinkle like traditional felt. The material resists mold growth, ensuring a dry and stable roof deck. Gator-Skin is up to 12 times stronger than traditional #15 felt, offering excellent wind resistance and durability even during heavy roof traffic and harsh weather conditions.

Gator-Skin is lightweight, with a nominal weight of 22.4 lbs per roll, and can be easily handled by roofing crews. Its advanced backside non-slip coating and 120 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.
