Common roof pitches and equivalent grade degree and radian angles. How to calculate square footage for rectangular round and bordered areas. 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. Access one of the rafters then take the measurement this way.

A flat roof has a slope of 2 in 12 or less. The calculator cannot account for complex shapes based on a measurement of square footage alone. There are two main categories of roofing. 1 300 x 1 05 1 365 square feet calculating the area true.

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.
