Product Overview

  • 20x stronger than #30 felt
  • 5x more coverage per roll than #30 felt
  • Withstands up to 6 months of exposure
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

Questions & Answers

Can this product be use in a flat mobile home roof??

Asked by: Maya
This is meant for use as an underlay for permanent roof covering, usually as a temporary covering to waterproof and protect roof sheeting during construction. It will not last long if left exposed as a permanent roofing material.

Yes, but much easier to work with . Has the nail pattern and overlap alignment line for the seams are printed on the outside service.

Product description is .04 after I order the product fella like .004

Asked by: ZZZ
Something isn't right here and perhaps the manufacturer should answer this question. The product description here says .04 inch thick which equals 40 mils (1000 mils to an inch). The product paper from the manufacturer says this material is 7 mils thick. That is equal to .007 inch. The observation by ZZZ that this material is .004 inch is probably closer to reality.

I've tried some really good synthetics, some of them easier than others to work with. This product is easy to work with, very lightweight and performs like the product claims to. I put it down to dry in a new deck and it literally poured buckets for two days after I got the decking covered before I could get the shingles on. Everything stayed bone dry. I was more impressed however with the "grip" providing excellent traction on a 10/12 pitch, even with some light dew on it. I will highly recommend this product and will buy again.

Rated 5 out of 5 by from This was recommended over stick-on type sub roofing, in particular... This was recommended over stick-on type sub roofing, in particular because it was being applied to older tongue and groove board roofing. Pros-Far superior to felt. Lighter, less prone to tears. I particularly like that, at angle intersections, such as peaks and valleys, excess material can simply be folded, without causing noticeable lumps. Can't do that with felt. It cuts very easily with a scissors-Much easier than cutting felt with a blade. The only annoyance is that it's so light, even a mild breeze can blow it around if you haven't had a chance to get a few nails in it. Count on a second set of hands, or even a third if its windy. The other con I'll mention is that duct tape can remove its surface. I left a flap unnailed, over the drip edge. As it was getting windy, I put a few pieces of tape on the edge to keep it down. Next day removing the tape, I realized if you start at the edge, it can pull off the shiny surface. Either leave the tape on, or peal toward the edge, not from the edge. Trivial concerns. I highly recommend this item.

Very easy to install; I did 26 foot lengths by myself on a steep pitch with no trouble. A couple of rain and snow showers have not got through to the decking, so seems pretty water-resistant. Much easier to handle than the self-stick stuff, and still seems to provide good protection. And it does seem to give good traction to walk on.
