1/9/2024 0 Comments Common rafter calculator![]() The result from Step 6 was 329 feet, so the length of the hip rafter is the square root of 326 square feet, or 18.1 feet. This calculator calculates the location of the plumb line for the heel cut on your rafter (lenght A to B), and the lenght of the matching seat cut. Once I have the run of the common rafters, I use the calculator to find the lengths of. Take the square root of the result from Step 6 to obtain the length of the hip rafter. a complex roof is one of the trickiest parts of home building. The length from Step 4 was 13.6 feet, and the length from Step 5 was 12 feet, so the sum of their squares is 13.6^2 + 12^2 = 329 square feet. Input Span & Pitch of your roof to quickly get bevel angles for: Common rafter length. Assume for this example that this distance is 12 feet.Īdd the square of the result from Step 4 to the square of the result from Step 5 to obtain the square of the length of the hip rafter. Measure the horizontal distance from a corner of the eave to the end of the roof's ridge. Length from ridge plumb cut to seat cut (underside): 406.27 cm. Rafter length from ridge to H.A.P (height above birdsmouth): 413.16 cm. The run of the roof in this example is 12.5 feet and the angle of the roof is 23 degrees, so the length of a common rafter is 12.5 / cosine 23 degrees = 13.6 feet. Total rafter length with overhang: 482.02 cm. The span of the roof is 25 feet, so the run of the roof is 25 / 2 = 12.5 feet.ĭivide the run of the roof by the cosine of the angle of the roof to obtain the length of a common rafter. Divide the span of the roof by two to obtain the run of the roof.
