This is a fairly common roof detail.
Pitch transition on metal roof.
One picture shows a view from above the pitch transition.
A roof pitch transition is a line in the roof plane that changes pitch.
Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12.
We need to do something where that change happens so the panels can go down and water can come off hit the lower slope and come off the roof.
You ll have a steeper part of your roof turning into a lower slope so there s a steeper pitch up top and a lower pitch on the bottom.
Pitch transitions are a common roof detail.
We see this quite frequently in log home roofs with porches for example.
The roof plane goes from one pitch to a lower pitch.
I m wondering if this transition flashing was installed correctly because it sits high above the ribs on the lower panels i was thinking it should more or less sit almost on top of the ribs.
The other shows a view underneath the pitch transition strip flashing taken from the lower flatter pitch of roof.
See the illustration below.
We re going to do a pitch transition or change.
Just simple 3d animated digital instructions on how to install transition trim on a masterrib metal roof.
Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs.
Low slope metal roofs require less material which reduces the overall load on the building s structure.
