1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
The average roof is 3 000 square feet or around 30 squares.
Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material.
Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
100 square feet 1 roofing square 9 290304 cubic meters si unit.
