How much felt paper do you need for 30 square roof?

Answer 1

Here's what I can help you with: 3 roofing squares means 300 square feet (1 square = 100 feet). On a regular basis, one square is covered by 3 bundles of shingles. Roofing felt (1F) is usually supplied in rolls (30 ' of length), with one side covered with sand or synthetic granules. Be aware that there are two kind of felt impregnations: bituminous and tar - there is a distinction between these two. If I were you, I would surely look (and go) for the newest waterproofing membranes, lot more less prone to puncture and tear. I hope this helped. Succes!

Answer 2

One square (as referred to in roofing) is equal to 100 sq ft. If you have 30 square than you multiply it by 100. A 30 square roof has 300 sq ft. as for the answer to your question it all depends.... there are two types of felt paper that are normally used in roofing. 15 pound and 30 pound. you simply have to look at the roll of felt paper you want to purchase and it will tell you how many sq. ft. it covers, normally 15 pound covers around 400 sq. ft. and 30 pound covers around 200 sq. ft. by the way you probably want to use 15 pound
