Where the porch roof extended over the shed roof we installed a 2x6 ridge that ran from the top of the.
Joining two roofs with different pitches.
For the next step of joining two roofs with different pitches you need to measure mark and cut two pieces of 1 by 1 lumber to work as the edges seals.
Prepare the area by identifying where the two different pitched roofs will meet.
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.
Position the flashing between the two roof pitches.
Joining two roofs of different pitches blind valleys simplify framing.
Just like what you do with the flashing slide the first piece under the higher roof first followed by placing the second piece under the lower roof.
Below are the steps on how to join two roofs together if they have different pitch.
Explore framing complexities that result when roofs of two different pitches intersect.
Joining two roofs with different pitches.
When done with the first step the next thing to do is measuring the.
Measure the length of joined area.
Step 3 prepare a piece.
Step 2 measuring the length of the joined area.
The piece that allows us to join the two different slopes is the pitch transition trim.
Add 12 inch to the length.
Step 1 preparing the area.
First we should establish the pitch of both roof planes.
How to join the roof pitches.
To keep the porch roof framing as simple as possible we installed a structural ridge.
One is getting the two differently pitched planes to meet at the hip or valley rafter.
When you want to join roofs in which the pitches are not in the same ratio the very first.
Pick the section where two edges will cross.
Slide the right edge of the flashing under the highest roof pitch.
The other is to get the fascias to line up.
A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration.
We ll start with the knowledge that the main roof has an 8 12 pitch.
