Hip Rafters With Different Roof Pitches

From simple to very complex computer generated hip roof designs.

Hip rafters with different roof pitches.

Discover 5 types of hip roofs plus 22 examples of many houses that incorporate all the different hipped roof styles. A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. On a related note the pitch properly the slope of a hip or valley rafter will not be the same as the pitch of the adjacent roof sections. Unit run of the hip.

Using a pitch measuring tool that i d made we also determined that the exact pitch of the shed roof was 3 1 2 in 12. 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. Before you cut your boards you ll need to measure the width of your building and calculate the exact length of each rafter. Learn more about off angle roof framing.

The hip roof framing calculator returns the value of the main rafter the side rafter the length of the hip the height of the knee wall and the lengths of the jack rafters. Select the following information by using the drop downs to enter values in feet and inches. A hip roof or a hipped roof is a style of roofing that slopes downwards from all sides to the walls and hence has no vertical sides. Modern residential hip roof construction uses common pitch ratios in general.

If you re framing a gable roof on a new house or building a shed or even a doghouse with a gable roof you ll need to cut a number of roof rafters. Blind valleys simplify framing. Explore framing complexities that result when roofs of two different pitches intersect. While the slope of the common rafters are expressed as x in 12 the slope of the hip and valley rafter on the same roof will be x in 16 97 so where two roof sections intersect to form a 90 angle a regular hip or valley and each roof.

But here it will be different since the hip rafter doesn t lie at 45 degrees to the commons. The roof rafters provide integral structural support to the roof. For example in an equal hip roof with an 8 12 pitch the pitch of the hip rafter would be 8 17.
