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. 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. Learn more about off angle roof framing.

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.

Gambrel roof a multi sided polygonal hip roof with steeply pitched slopes that rise to a peak similar to what you d see on a church steeple. The other is to get the fascias to line up. 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.

We ll start with the knowledge that the main roof has an 8 12 pitch. First we should establish the pitch of both roof planes. Select the following information by using the drop downs to enter values in feet and inches. Joining these two roofs poses two main challenges.

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. One is getting the two differently pitched planes to meet at the hip or valley rafter.
