Joining two roofs of different pitches blind valleys simplify framing.
Transition joining two roofs with different pitches.
The shingles may overlap to provide full coverage for the combined roof.
This allows water to flow off the upper panels out over the trim onto the lower panels and exits the roof at the eaves.
Slide the right edge of the flashing under the highest roof pitch.
Joining these two roofs poses two main challenges.
Place the 2 by 4 inch piece of lumber along the center of the flashing.
Before joining two roofs with different pitches you can temporarily remove the eaves trim and replacing it after completing joining the roofs.
The roof is now combined and you re now good to go.
One is getting the two differently pitched planes to meet at the hip or valley rafter.
We ll start with the knowledge that the main roof has an 8 12 pitch.
Where the porch roof extended over the shed roof we installed a 2x6 ridge that ran from the top of the.
After that cut each of them to fit the length of the joined area.
As a final touch cover the flashing with shingles.
First we should establish the pitch of both roof planes.
To keep the porch roof framing as simple as possible we installed a structural ridge.
The other is to get the fascias to line up.
We re going to install it over top of the panels that have already been installed on the lower slope.
Position the flashing between the two roof pitches.
Take a piece of the lumber and then slip it under the roof pitch that has a higher position.
