Hip rafters with different roof pitches.
From simple to very complex computer generated hip roof designs.
Explore framing complexities that result when roofs of two different pitches intersect.
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.
Blind valleys simplify framing.
For example in an equal hip roof with an 8 12 pitch the pitch of the hip rafter would be 8 17.
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.
Unit run of the hip.

But here it will be different since the hip rafter doesn t lie at 45 degrees to the commons.
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.
