Porch joining two roofs with different pitches.

Joining two roofs of different pitches blind valleys simplify framing. First we should establish the pitch of both roof planes. This technique is beneficial particularly in home expansion. Position the flashing between the two roof pitches.

The piece that allows us to join the two different slopes is the pitch transition trim. Place the 2 by 4 inch piece of lumber along the center of the flashing. Gable roofs have two sloping surfaces from the ridge usually in the center joining at the side walls. Joining these two roofs poses two main challenges.

Joining two roofs of different pitches. There are two ways i know of to attack these problems. A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. One is by using trigonometry.

Where the porch roof extended over the shed roof we installed a 2x6 ridge that ran from the top of the. The other is to get the fascias to line up. We ll start with the knowledge that the main roof has an 8 12 pitch. They can be seen on many ranch homes and porches throughout the country.

One is getting the two differently pitched planes to meet at the hip or valley rafter. This allows water to flow off the upper panels out over the trim onto the lower panels and exits the roof at the eaves. If the roof faces are the same pitch and bear at the same height then it s all 45º angles. But when you have different pitches and or different plate heights it gets a little tricky.

Explore framing complexities that result when roofs of two different pitches intersect. If by any chance right now you are looking for the information about how to join two roofs if they have different pitches here we will share all the information we know with you. We re going to install it over top of the panels that have already been installed on the lower slope.
