Tarco LeakBarrier PS200HT Ice and Water Armor Modified Bitumen Roof Underlayment 36 in x 66 ft, 200 sq ft

Tarco LeakBarrier PS200HT Ice and Water Armor Modified Bitumen Roof Underlayment is a professional-grade, self-adhesive SBS-modified bitumen underlayment engineered to provide superior ice-and-water protection beneath tile, metal, slate, or asphalt shingles. Each 36 in × 66 ft roll covers 200 sq ft and features a glass-fiber reinforced, high-strength surface that resists tears during installation while providing excellent slip resistance for enhanced safety on the roof deck.

Because this underlayment is made from rubberized asphalt with a proprietary hybrid polymer system, it does not absorb water or wrinkle like traditional felt. The material acts as a continuous vapor barrier and self-seals around fasteners to prevent leaks. PS200HT’s modified bitumen construction resists mold growth and remains flexible in cold temperatures, ensuring a stable, dry roof deck under any weather conditions.

PS200HT is contractor-friendly and easily handled on the job site. Rolls are pre-weighted at 70 lb (low-slope) or 28 lb (steep-slope) for easy carry and placement. The non-slip polyester-surfaced top and aggressive adhesive backing allow for fast, wrinkle-free installation and secure adhesion even in high winds.
