Grace Tri-Flex Xtreme is an innovative synthetic roofing underlayment featuring an advanced skid-resistant technology. It provides a superior walking surface in both dry and wet conditions on steep-slope applications. The product is extremely strong, durable, lays flat and is easy to install. It provides outstanding water-shedding protection to the roof and thus represents the next generation in synthetic roofing underlayments.

  • Grace tri-flex xtreme can be used to provide a temporary water-shedding protection to the roof before the primary roof covering is installed. This allows for flexibility in accommodating construction schedules
  • Skid resistance - tri-flex xtreme is specifically engineered using a breakthrough anti-skid technology (patent pending) to ensure unmatched performance both under wet and dry conditions. Its skid-resistant properties have been evaluated and endorsed by experienced contractors around the country
  • Durable - unlike conventional roofing felt that typically buckles and telegraphs after exposure, tri-flex xtreme can withstand extreme weather conditions and still remains flat. This is even more important when drying in the roof. It does not dry out or rot at high temperatures; it does not crack or become brittle at low temperatures; it does not shrink after hot and cold temperature cycles. Product can be left exposed for up to 120 days
  • Strength - it is 15 times stronger than #30 felt and also stronger than many synthetic underlayment. Tri-flex xtreme is designed for superior strength and durability - it does not tear away from nails, even in high wind conditions
  • Lays flat and stays flat - the unique woven technology and proprietary coatings enable tri-flex xtreme to lay flat - free of wrinkles and other defects. It remains flat even after exposure to the elements
  • Light weight - one roll weighs about 31 lbs - nearly 9 times lighter than #30 felt and significantly lighter than competitive synthetic underlayment’s. Contractors can cover more area with fewer trips up the ladder, increasing installation efficiency and saving labor cost
  • Fast and easy installation - the light rolls and convenient dimensions make even one-person application fast and easy, increasing installation productivity
  • Grace technical support - grace tri-flex xtreme is backed by a team of local technical support personnel that help ensure every application goes smoothly. Grace tri-flex xtreme has a 20 year warranty

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by outstanding durability and easy to work with used for re-roof on my tile roof. the ability to fold/turn at edges (rakes, skylights, chimneys, walls) is awesome. felt will crack with that type of movement--if not immediately, over time w/heat and water exposure. very good traction, even with dusty conditions. high confidence in this product's ability to last (taped a piece to my stucco wall and left exposed for 6 months so far...it looks great). i did silicone the top-side of each batten, just above each nail driven into the batten ( to minimize water migration)...cap nails used sparingly to secure to the deck until battens laid down. caution...working (1 man) on a windy day is near impossible...this stuff is like a kite when wind catches it. this high-end version is superior to the base model tri-flex (black), regardless of the longer warranty and greater exposure time offered on the base tri-flex. the base tri-flex feels like a cheap grocery store bag and Xtreme feels like a heavy-duty, puncture resistant trash bag.
