Hip Rafters With Different Roof Pitches

Whilst it may sound ridiculous today they are used quite a lot these days to make a home look a bit more unique than others on the market.

Hip rafters with different roof pitches.

For example in an equal hip roof with an 8 12 pitch the pitch of the hip rafter would be 8 17. This calculator returns the first 16. Managing a hip roof with two different pitches one thing that has become far more popular in recent years is the usage of hip roofs that have an alternative pitch at one side to the other. 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. 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. The only method that is 100 foolproof to find the values for all jack rafters no matter what the pitch or even if they are on different pitches is to physically measure the long rafter and the short rafter and then divide the difference by the number of spaces. Blind valleys simplify framing.

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. To keep the porch roof framing as simple as possible we installed a structural ridge supported by posts at each end with the common rafters landing on top of the ridge. Explore framing complexities that result when roofs of two different pitches intersect. 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. From simple to very complex computer generated hip roof designs. A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. Learn more about off angle roof framing.
