Calculate square footage for a roof by measuring and by performing some basic math equations.
Formula for figuring square footage of a 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.
1 300 x 1 05 1 365 square feet calculating the area true.
Calculate square footage square meters square yardage and acres for home or construction project.
The only difference in this calculation to the one for a gable roof area is the amount of the ridge.
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.
To accurately calculate the area of your roof you must first determine its slope or pitch.
Add the square footage for all the planes together.
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.
Calculate square feet meters yards and acres for flooring carpet or tiling projects.
With the area measurement you can learn the approximate cost of a new roof.
If you have a simple gable roof you ll only need to measure and sum up the 2 planes of the roof.
Determine the square footage of one floor of your home.
The top ridge will be shorter than the one of the gable roof but the four hips will add.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
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.
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.
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.
Find the square footage of the roof.
The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.
The result is the total square footage of your roof.
