How to find how many square a roof is.

The calculator cannot account for complex shapes based on a measurement of square footage alone. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. 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. Convert the area to roofing squares.

Now in order to determine how many squares are there on the gable roof for example all you need to do is divide the total square footage by 100. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. To accurately calculate the area of your roof you must first determine its slope or pitch. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100. 100 280 squares. The answer is the number of roofing squares for the roof. A square is an area of roof which measures 100 square feet.

You will need to express this size in terms of square feet. In cases where a roof has a complex shape such as in the image to the right measuring the dimensions and areas of each part of the roof to calculate total area will result in a more accurate measurement of area. Total square footage from example 2 above. To determine the number of squares on the gable roof above simply divide its total of 24 000 square feet by 100.

Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure.
