Rated 4.8 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by very easy purchase The roofing underlayment is a very good product. shipping was very fast. May 12, 2015
Rated 5.0 out of 5.0 by Just Comparing In comparing many roofing underlayment options, this one seems like a no brainer. It is highly recommended to use 30# felt, which as you know can be a pain to get perfectly level. 1 roll of 30# covers about 200 sq ft, this stuff covers 1000 sq ft, which makes it overall about 25% cheaper versus buying 5 rolls of felt. So a better product, an easier installation, a better price and a higher quality roof and less rolls to carry on a roof........I'm all over it! July 27, 2014
