Frequently Asked Questions: 12×16 Shed Roofing Calculator (Shingle Bundles)
How many bundles of shingles for a 12x16 shed?
You will need 9 bundles of shingles (3 squares) to reroof or build a 12x16 shed with a 6/12 pitch.
Can you use roll roofing instead of shingles on a 12x16 shed?
Yes, but mineral surface roll roofing is only recommended for very low slope roofs (2/12 to 4/12). At 6/12 pitch, architectural shingles provide much superior 30-year waterproofing and aesthetics.
