Owens Corning WeatherLock Specialty Tile & Metal Rubberized Asphalt Roof Underlayment 36 in x 71.3 ft, 214 sq ft

Owens Corning WeatherLock Specialty Tile & Metal Rubberized Asphalt Roof Underlayment is a professional-grade underlayment engineered to provide superior waterproof protection beneath tile and metal roofing. Each 36 in × 71.3 ft roll covers 214 sq ft and is designed with a high-strength, nonwoven polyester surface that resists tears during installation. This advanced construction lays flat and provides a slip-resistant walking surface to enhance safety and ease of use during installation.

Because the underlayment is made from durable rubberized asphalt and synthetic fabric, it does not absorb water or wrinkle like traditional felt. The material resists mold growth and provides a watertight seal around fasteners, ensuring a dry and stable roof deck. WeatherLock Specialty Tile & Metal is significantly stronger than traditional #15 felt, offering excellent resistance to wind, UV, and harsh weather conditions—even under heavy roof traffic.

WeatherLock Specialty Tile & Metal is lightweight and easy to handle for roofing crews. Its split silicone-release backing and up to 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.
