A table showing the hip and valley factor hip and valley design pdf download common roof pitches. Also provides the underlying equation for the factor.
The hip and valley factor is a number that is multiplied by the actual run horizontal distance of a common rafter to determine the length of a hip or valley rafter.
Also see the Roof Pitch Multiplier Table. Repeat, the actual runnot the lengthof a common rafter. For precision, the thickness of the ridge board and any eave overhang should be taken into account when determining the run. The hip and valley factor varies according to the slope of the roof, as shown below. This one is very good. Roof Pitch Multiplier Table. Roof Slope Equivalents. They're free and easy to use.
