Surely it must be possible to apply a simple multiplier to the pitch angle say 30 deg to derive the hip angle. Mark the length of the hip measuring down from the longest point of the plumb cut. They are almost always at the same pitch or slope which makes them symmetrical about the centerlines.

Select the following information by using the drop downs to enter values in feet and inches. Take the run of the main roof 9 feet and using your square and the pitch of the hip in relationship to the main roof 8 inches and 15 58 inches step off this distance in the conventional manner. 2 Hip roof the roof base is a rectangle two sides are identical isosceles triangles and two sides are identical trapeziums.

Does anyone know what the normal multiplier might be where the hip pitch is the same as the main pitch. Hip roofs on houses could have two triangular sides and two trapezoidal ones. Place the 2-by-4-inch piece of lumber along the center of the flashing.

One expression of a hip roof pitch based on this formula would be 412 meaning a 4-inch vertical rise for every 12 horizontal inches. Then measure down that plumb cut the same distance as the common rafters height above plate. Inches Enter the pitch of the roof.

A square hip roof is shaped like a pyramid. In a hip roof with equal pitches the unit run of a hip or valley rafter is 17 inches for every 12 inches of run in the main roof. Position the flashing between the two roof pitches.

Enter the width of the building. Feetinches Enter the overhang of the eaves. Generally speaking the four roof planes all have the same pitch slope and the ends of the roof ridge are often ornamented with a finial or hip knob.
