I have a small shed roof to re-shingle. It now has roll roofing on it. I would prefer tab shingles, but the guy at HD said he did not think it is not steep enough. I could tell he was not sure of his answer, which to me means he was only taking a guess.
The roof is 12 feet from peak to drip edge, and is 13 inches higher at the peak. That means just a tad over one inch drop per foot.
Is that enough for shingles? I really hate roll roofing, and I already have enough shingles (or almost enough). They are left overs and the roof will be several colors, so if I got to buy one more bundle it will still be the cheapest way to go. Otherwise I may use tin, because roll roofing never seems to last long, and is a pain in the butt to apply since all the joints need messy tar.
