If the shingles you are using come three bundles to a square, calculating the number of bundles youâll need is simple. Each bundle covers 33.3 sq. ft. of roof areaâclose 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 youâll have the total number of squares needed to cover the roof.
There are many different types of shingles on the market. The standard 3-tab Owens Corning Classic 20 year shingle weighs approximately 66 pounds per bundle. There are 22 shingles per bundle, and it takes 3 bundles to cover one square of roof (100 square feet). The Berkshire series put out by Owens Corning averages about 360 pounds per square, has nine shingles per bundle, and there are 5 bundles to the square.
