The primary function of these two items is for sealing the edges of the roof.
Transition joining two roofs with different pitches.
We ll start with the knowledge that the main roof has an 8 12 pitch.
The roof is now combined and you re now good to go.
We re going to install it over top of the panels that have already been installed on the lower slope.
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.
As a final touch cover the flashing with shingles.
After that cut each of them to fit the length of the joined area.
Take a piece of the lumber and then slip it under the roof pitch that has a higher position.
The piece that allows us to join the two different slopes is the pitch transition trim.
Slide the right edge of the flashing under the highest roof pitch.
Place the 2 by 4 inch piece of lumber along the center of the flashing.
First we should establish the pitch of both roof planes.
This allows water to flow off the upper panels out over the trim onto the lower panels and exits the roof at the eaves.
One is getting the two differently pitched planes to meet at the hip or valley rafter.
Position the flashing between the two roof pitches.
To keep the porch roof framing as simple as possible we installed a structural ridge.
Joining these two roofs poses two main challenges.
Joining two roofs of different pitches blind valleys simplify framing.
