LeakBarrier NR600 Ultra Ice and Water Armor

Brand: Tarco Roofing

LeakBarrier NR600 Ultra Ice and Water Armor is a state-of-the-art SBS modified, non-reinforced, self-adhesive roofing underlayment for use under tile, metal, slate, and asphalt shingles. 

Surfaced with a highly durable polyester reinforcement that provides exceptional strength and excellent walkability, NR600 Ultra is specially formulated for use in high temperature environments and self-seals around nails. 

The unique self-adhesive compound on the side lap ensures an immediate bond between adjacent rolls, resulting in instant watertight laps.

LeakBarrier NR600 Ultra is a premium underlayment designed to prevent leaks caused by ice and water damming and wind-driven rain. 

Ideally suited for use in mechanical and foam-attached tile roof systems, it is also an excellent choice as an underlayment for shingles, slate, and metal. 

NR600 Ultra is highly effective in critical roofing areas such as valleys, ridges, coping joints, chimneys, vents, dormers, skylights, and low-slope sections
