The most common roofing materials used in the united states include shingles membrane roofing and ceramic tile all of which have different life spans. To determine the number of squares on the gable roof above simply divide its total of 24 000 square feet by 100. To find the squares divide the overall roof area by 100 and then round up. Your roofer will know that steeper roofs use more shingles than lower sloped roofs for the same house size and there are established slope multiplier factors to make this calculation simple see table below.

The result is 240 and this means you would need 240 squares of shingles to cover that roof. A square is an area of roof which measures 100 square feet. A square is the number of shingles it would take to cover 100 square feet of roof area with each row of shingles covering the tabs of the layer below it. This is simply 100 square feet of roof.

For example a very steep roof on a 1 000 square foot attic will need more shingles than a lower sloped roof on the same sized attic. Roofing contractors estimate projects and materials by the square so it is crucial to find this measurement to accurately estimate the amount of material needed.
