Ratings & Reviews for GAF WeatherWatch Ice and water shield 36-in x 50-ft 150-sq ft Polypropylene Roof Underlayment

Easy apply, self-sealing, well worth the cost

I started using this on a low-slope porch roof (2-12) because it was much easier to apply than multiple layers of 30# felt and it meets FL building code. It was so easy to apply I bought enough to do my whole house roof. Easy to peel backing I was able to lay the whole roll at one time, unroll it where you want it and let it sit for about 15 minutes (to acclimate to laying flat), then slip the backing out from underneath and it's stuck down! Much better than traditional felt and only nails requi...

Roof Underlayment

I have used this product on 1000 sq ft shop roof last year. It is very easy to install and much more efficient than paper felt. It has made me very satisfied that I will not have any more roof leaks. Now I am installing it on my house roof. It provides immediate protection from rain getting in the roof. The adhesive is very strong and leaves me no doubt about it’s quality. It’s worth every penny more than traditional felt.

Easy to install

Easy to install. To early to see if it will start leaking for what I’m using it for.

Great product

Adhesive backing is easy to apply. Added protection!

Best underlayment on the market

Have used this product for many years on my own home and on others

Good roof underlayment

Good roof underlayment, pretty easy to use once you get the hang of putting it down, Don't let the sticky surface come into contact with each other. Bonds instantly to the roof decking when laid down and by overlapping the seams it should seal the roof completely and provide a excellent secondary water barrier. I wish this material was available when I first put my roof on many years.

Good product

We like this product. We used it when we built dog house. It works well.

Good underlayment

Building a shed and used it for the underlayment on the roof. 4 star just because it’s very slippery. Other than that, good stuff.

Water tight

This product is the best and can be used in multiple applications

YOUVE GOT TO BE KIDDING ME

if you like wasting time and being aggravated then then buy this product the backing on the top side is impossible to remove. Lowes should take this off the shelves and throw it in the garbage where it belongs
