NOT WATERPROOF!!
IF your shingling the same day your good, If it rains WATER POURS IN!!! Product description VERY misleading, seriously guys the whole idea of getting the felt down is so the house doesnt leak.

Response from GAFProductExpertDec 1, 2020
Hello, we're sorry for your experience, but this product is not designed to be a temporary roof or left as a "dry-in" solution. This limitation is specifically noted in the detailed installation instructions on each roll wrapper. It is meant as a secondary layer of protection under the final roof covering - asphalt shingles. If you're looking for a "water proof" solution, a peel and stick underlayment that has the ability to self-seal around the fasteners is the best solution. When you fasten through most synthetic underlayments they do not have the ability to self-seal around the fasteners and thus when left exposed to heavy rainfall, water can infiltrate at those points. In addition, the product itself, without fasteners, is tested per ASTM D4869 4 hour shower testing to ensure that water simply doesn't penetrate through the product. Thank you. gaf

    I used both this and the Owens Corning comparable product. I like this better as it is a little easier to use and it is an extra 6 inches wide.

      worth every dollar
      I have a concrete Spanish tile roof built in 1966 and leaked for over 10 years. we bought the house in 2014. rained outside and inside. my wife and I removed all the tiles(1500) and I put the GAF underlayment in as per the video and it looked great. this week it poured for 6 straight days and no leaks. I only have a 1400 sqft roof and the actual underlayment installed in 4 hrs. Thank you GAF Craig. Fallbrook,ca

        cant tell you how amazing this stuff is
        Last october i bought this stuff after reading the reviews. It was also suggested to me by an old friend. For the people who say its slippery... 1. There are two sides to it. Yes one side is very slippery. 2. Do not step on it until it has the appropriate amount of cap nails. I installed this with cap nails and was scepticle at first. Then we were hit with a monsune in November here in Pa, ans it rained alot throughout the winter. We also had some very severe wind storms (two 60 mph windy days) and many other days of 40 mph winds. Understand we live on top of a hill, so wind is brutal. Not only did this stuff not leak, but it didnt rip or tear. We did not even nail every marked place, we only nailed every other three. WOW!!! I love this stuff. It also has a nice texture to it that made it so easy to walk on a 5/12 roof. Its. Now April, and we just got the roof on. There were no tears, no wearing, no shrinking, no leaking. (Oh, be sure that the cap nails are installed flush/evenly not bent over) Would recomend this to anyone. Install properly and you wont have a problem.
