WebJun 7, 2024 · Pitch = tan , where angle is pitch of roof expressed in degree. Here you have given roof pitch = 4/12 and span of about 30 feet, then run = span/2, hence run = 30/2 = 15 feet, you know pitch = rise/run, so 4/12 or 1/3 = rise/run, hence rise = run/3, putting the value of run you can get rise = 15/3 = 5 feet. Calculate the rafter length for 4/12 ... WebCalculate the rafter length for 6/12 roof pitch, as Rafter^2 = rise^2 + run^2, Rafter^2 = 7.5^2 + 15^2, Rafter^2 = 56.25+225, rafter = √281.25, Rafter = 16.77 feet or 5.11 meters, hence rafter length for 6/12 pitch roof will be 16.77 feet long.
