Very easy to apply. I live in Oregon and put this on my patio before I got my roofing. It rain for 2 weeks straight on it with zero leaks and my roofing OSB boards stayed completely dry.

I put a roof on 10 years ago with this under it. It sat for a month open to the air. I used felt tabs and nails and then put gorilla tap over them so water would not get in. Worked perfect. Since then I helped a friend with a leaking valley on his roof with this stuff. He didn’t have the money to do his roof. I rolled it on and overlapped it all the way over the peak on both sides. About 20 foot total. I did the same method as my roof. It puddles in the bottom due to a bad slope. 3 years later he still has no leaks. I am convinced this stuff can be left out forever and do a great job sealing the roof. I also use this to lay over my wood pile and keep the water off. Simple and effective.
