A typical 4 foot by 8 foot sheet of plywood covers 32 square feet. If your roof area is 1,600 square feet, 1,600 divided by 32 will mean you need about 50 sheets to cover the roof. Add 10 percent to allow for waste.
Then, add the two planes together to derive the total square footage of the roof: 1  Plane 1: 120' x 100' = 12,000 sq. ft. 2  Plane 2: 120' x 100' = 12,000 sq. ft. 3  Plane 1 + Plane 2 = 24,000 sq. ft. for the total square footage of the roof. Roof surfaces are measured in squares. A square is an area of roof which measures 100 square feet. To determine the number of squares on the gable roof above, simply divide its total of 24,000 square feet by 100. The result is 240, and this means you would need 240 squares of shingles to cover that roof.
