how many square feet are in a bundle of shingles
If the shingles you are using come three bundles to a square, calculating the number of bundles youâll need is simple. Each bundle covers 33.3 sq. ft. of roof areaâclose enough to the 32 sq. ft. a sheet covers. So just order one bundle for each sheet of roof sheathing. For other bundle counts per square, divide the number of sheets of sheathing by three and youâll have the total number of squares needed to cover the roof.
