How to Calculate Rafter Lengths?

Answer

To calculate rafter lengths requires one to select the pitch of the roof. Amount the building from the outermost part of the wall to the center of the building. Compute the pitch of the roof as a decimal. Increase this decimal by the overall run to obtain the overall rise. Analyze the length of the rafter using the Pythagorean Theorem, that is the hypotenuse of a right triangle, square root of run squared + rise squared. Compute the length of your rafter overhang using the same method.
