Platinum Underlayment

WESTMAN STEEL’S PLATINUM synthetic roof underlayment is the new generation of roof protection, and is among the safest, strongest, and best-performing on the market. With its GRIPSPOTTM Technology, these panels offer the ultimate anti-slip protection. Woven of heavyweight polymer fabric, it offers superior strength and durability, a wrinkle-free surface and a strong resistance to UV-breakdown. GRIPSPOTTM TECHNOLOGY is your ultimate protection on the roof, working in any weather condition. With its raised fibrous spots for traction and smooth channels for shedding water, this material provides outstanding slip resistance. PLATINUM is light-weight, easy to carry and pliable under extreme temperatures and stays put with its non-slip underside coating. All of these features combined with its print design result in easier, faster and more accurate installations. PLATINUM can be used in most types of installations, whether they are commercial or residential. It can be used with metal, wood, and asphalt shingles, and slate or concrete tiles.
