Gable Joining Two Roofs With Different Pitches

This plan shows as much irregularity as can be desired and as much as is generally encountered in actual practice.

Gable joining two roofs with different pitches. We re going to install it over top of the panels that have already been installed on the lower slope. This allows water to flow off the upper panels out over the trim onto the lower panels and exits the roof at the eaves. Joining these two roofs poses two main challenges. 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.

It will be noticed that the left gable has two different pitches. Joining two roofs with different pitches is a method that exists in the building and construction world. The front gable d f g is 18 feet wide and has a rise of 8 feet. One idea i had was to sort of combine hip and gable roofs by doing the two roof peaks on the left the lower pitches with a little shed roof going across the entirely of the gable right above the garage doors for example and making doing a traditional rake gable edge on the porch entry.

Joining two roofs of different pitches blind valleys simplify framing. We ll start with the knowledge that the main roof has an 8 12 pitch. Learn more about off angle roof framing. The last gable j i h is 21 feet wide and has a rise of 8 feet.

To keep the porch roof framing as simple as possible we installed a structural ridge. Explore framing complexities that result when roofs of two different pitches intersect. That sounds worse than what you have. The piece that allows us to join the two different slopes is the pitch transition trim.

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