Hip Roof With 2 Different Pitches

Explore framing complexities that result when roofs of two different pitches intersect.

Hip roof with 2 different pitches.

A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. One is getting the two differently pitched planes to meet at the hip or valley rafter. 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. First we should establish the pitch of both roof planes.

The other is to get the fascias to line up. 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. Box gable roof a type of hip roof where each side includes two different sloping angles with the lower angle much steeper than the upper angle. From simple to very complex computer generated hip roof designs.

Discover 5 types of hip roofs plus 22 examples of many houses that incorporate all the different hipped roof styles. 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. Joining these two roofs poses two main challenges. 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.

We ll start with the knowledge that the main roof has an 8 12 pitch. Learn more about off angle roof framing. Select the following information by using the drop downs to enter values in feet and inches. 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.

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. 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.
