How abundant three tab shingles I entail to cover a roof nouns 20x20?
Answers: Shingles are sold by the square. A roofing square is 100 square feet. You hold 400 square feet so 4 bundles. But this also depends on the overlap of the shingles. If you enjoy severe weather you will want to have more overlap and will necessitate more shingles. It will say on the shingle pod waht overlap to use to get 100sq ft from the bundle.
