Product Overview

Tri-Flex XT underlayment is a high strength woven synthetic roofing underlayment coated on both sides with slip resistant polymers. The new and improved coating formulation provides superior foot traction. This composition creates a tough, weather-resistant membrane designed to perform in the harshest conditions in North America.
  • Improved slip resistant surface - new coating provides superior foot traction
  • Lighter and covers more area - a roll of underlayment is around half the weight of #30 felt, and has nearly 5 times the coverage
  • Stronger - Tri-Flex XT roofing underlayment is 20 times stronger than felt and won't tear away from nails even in high winds
  • More durable - Tri-Flex XT underlayment can be left exposed for up to 6 months, it doesn't dry out or rot at high temperatures and doesn't crack or become brittle at low temperatures
  • Facilitates faster and easier installation - the lighter rolls make the 1-person application fast and easy, it also means fewer trips up the ladder and lower labor costs
  • Replaces the discontinued item: Tri-Flex 48 in. x 250 ft. synthetic roll roofing underlayment
  • Grace construction products are now brought to you by GCP Applied Technologies
  • Complies with ASTM E108/UL 790 for use in the installation of Class A asphalt glass fiber mat shingles and Class C asphalt organic felt or metal shingles

Great product! Lightweight and extremely durable. I've had it exposed for 30 days or so while the roofing is on order. No leaks and no problems. Everyone who has worked on the roof has commented about how slip-resistant it is compared to felt. If it's put down according to the manufacturer's specifications this works incredibly well. There is another version of Tri-Flex called Tri-Flex 15 that I have not used. I highly recommend the XT version.

Tri Flex is a fantastic underlay for shingles or metal roofs. It's very tough, and if you have to wait on your shingles to be delivered the UV rays don't harm it if it is several months before final roofing can be installed.

We put the Tri-Flex on in December - dumb time to roof where we live. It is very easy to put down, marked out with little circles so you know where to nail. It is on the windy side of the roof but it is staying in place. We used the capped nails and staples to fasten it down. It was not as slippy to walk on as the bare board roof even with the morning frost. Very happy SO FAR with the item - hoping it will last until spring when we can finish the roof with the shingles. That is why I only gave it a 4 rating - time will tell.

This is a very strong underlayment that is wind proof and water proof. Excellent grip for your feet even when wet. It has marks everywhere you should put a nail. This product made my roof much stiffer to walk on after installed with shingles. I would recommend this to anyone putting on a new roof or covering an existing one.
