how many sq feet in a bundel of roofing shingles .?

Question

i would like to reroof my tool shed that measures 12x12 total roof. how many bundels of shingles will it take. thank you

Answer 1

Depending on the type of shingle, you usually have three bundles to one square (100 sq. ft.). So each bundle covers about 33 sq. ft. 12x12=144 sq. ft, so you want 5 bundles of shingles. This will give you extra for ridge cap and future repairs.
Thats for a regular 3 tab asphalt shingle. If you use architectural shingles, they come four bundles to the square, each bundle covering approximately 25 sq. ft., so if you use architectural, you'd want at least 6 bundles, but I'd get 7 to account for waste and future repairs.

Answer 3

Bear Down was right about 3 bundles to a square (100 sq ft.)
I think you use a few extra shingles with the starter shingles also. It is the shingles on the edge of the roof that is turned backwards to keep water from leaking where the tabs are split.

They differ between types. Usually you order Squares of shingles, one Square is 100 sq ft.
