Figuring Roof Square Footage

To calculate the size of the roof you need to measure the size of the roof as if it were flat account for roof pitch calculate square footage and finally determine how many squares of material are required for the roof the calculator above can handle all of this simply enter the length width and pitch and it will determine the size of the roof in squares.

Figuring roof square footage. Next you will need to use a roofing materials calculator. When calculating square footage for your roof always add at least 10 percent of the total to account for waste. The square footage of a hip roof area is identical to the square footage of a gable roof of the same size. 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.

The calculator cannot account for complex shapes based on a measurement of square footage alone. Calculate square footage for a roof by measuring and by performing some basic math equations. Check that your footage measurements are within this range so you can start off on the right foot. 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.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. Calculate the square footage area of a hip roof. With the area measurement you can learn the approximate cost of a new roof. The top ridge will be shorter than the one of the gable roof but the four hips will add.
