Had the old style covering on my roof. Re-did the roof and decided to try this material as it was less weight to bring up on the roof. Worked great and easy to use. I am happy with it.

It is by far the toughest roof underlayment I have ever used. Lays really flat and stands up to the elements. I have had it on my shop for 2 years, couldn't get back to working on it and it has been amazing.

Our community is recovering from a devastating wildfire. We built a 20’ x 40’ covered area for our hot tub and patio area. We are in the process of rebuilding the house but aren’t ready for roofing. This product has weathered direct rain and sun beautifully, and stays smooth. It was super easy to install and we will be using this on all of our outbuildings !!
