Customer Reviews for GMCraft 72 ft. x 40 in. 60-Minute Building Paper

Great product and worked perfect as it should.

Just what I needed and expected. I only wish it was available in smaller quantities for doing patches.

Good quality nice thick underpayment paper. I’m replacing old windows in a 70YO house and using this as underpayment for metal lathe then stucco. Easy to cut with regular scissors.

Too expensive, supply house has better prices.

Im not a roofer, but ive been in Construction for 50 years and have done many roofing jobs, last one about 23 years ago. Ive always used 30lb felt paper (30 lb tar paper) because the 15 lb was too flimsy to put down too far in advance of shingling over it. The wind just tears 15 lb paper to pieces. So i assume the 60 minute craft paper means only leave uncovered for no more than 60 minutes, or the Sun will deteriorate it, making it unable to be usable. I only did a few minor repairs with this product and learned quickly how to make use of it. Once again, I'm not a professional roofer, just a General Contractor who occasionally roofs.
