Formula For Figuring Square Footage Of A 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.

Formula for figuring square footage of a roof. Calculate square feet meters yards and acres for flooring carpet or tiling projects. How to calculate square footage for rectangular round and bordered areas. 1 300 x 1 05 1 365 square feet calculating the area true. The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.

Determine the square footage of one floor of your home. The calculator cannot account for complex shapes based on a measurement of square footage alone. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. 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.

To accurately calculate the area of your roof you must first determine its slope or pitch. Calculate square footage square meters square yardage and acres for home or construction project. Find the square footage of the roof. Add the square footage for all the planes together.

Enter measurements in us or metric units. 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. Calculate square footage for a roof by measuring and by performing some basic math equations. Calculate the square footage area of a hip roof.

The top ridge will be shorter than the one of the gable roof but the four hips will add. 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. Calculate project cost based on price per square foot square yard or square meter. 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.

The only difference in this calculation to the one for a gable roof area is the amount of the ridge. The result is the total square footage of your roof. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
