APOC Weather-Armor HT2 High Temperature Roof Underlayment 39 in x 65.67 ft, 200 sq ft

APOC Weather-Armor HT2 High Temperature Roof Underlayment is a professional-grade underlayment designed to provide superior protection beneath metal, tile, shingle, or slate roofing. Each 39 in × 65.67 ft roll covers 200 sq ft and is engineered 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 modified bitumen with a high melt polypropylene surface, it does not absorb water or wrinkle like traditional felt. The material is highly resistant to heat and mold growth, ensuring a dry and stable roof deck. Weather-Armor HT2 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.

Weather-Armor HT2 is lightweight, with a nominal weight of 65 lbs per roll, and can be easily handled by roofing crews. Its advanced backside non-slip coating and 90 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.
