Formula for figuring square footage of a roof.

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. Calculate the square footage area of a hip roof. Measure the length and width of each portion of the roof multiply length by width for each plane and then add the planes together for the total square footage. The top ridge will be shorter than the one of the gable roof but the four hips will add.

Determine the square footage of one floor of your home. Calculate square feet meters yards and acres for flooring carpet or tiling projects. The only difference in this calculation to the one for a gable roof area is the amount of the ridge. Enter measurements in us or metric units.

To accurately calculate the area of your roof you must first determine its slope or pitch. Calculate project cost based on price per square foot square yard or square meter. If for example the total square footage for the examples used so far would be 14 400 the rectangular plane plus 900 the triangle plus 2 000 the irregular shape 17 300 square feet. Calculate square footage square meters square yardage and acres for home or construction project.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. If you have a simple gable roof you ll only need to measure and sum up the 2 planes of the roof. 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. For example if you have a two story home that s 2 600 square feet one floor would be 1 300 square feet multiply this number by your most recent result to get the estimated square footage of your roof.

The square footage of a hip roof area is identical to the square footage of a gable roof of the same size. The calculator cannot account for complex shapes based on a measurement of square footage alone. Find the square footage of the roof. Calculate square footage for a roof by measuring and by performing some basic math equations.

So continuing our example if you ve got a two story house with a total square footage of 2 700 square feet with each floor having 1 350 square feet multiply 1 350 by 1 0541 to get 1 423 square. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. The result is the total square footage of your roof.
