Pitch transition on metal roof.

Masterrib is a 36 w. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. One picture shows a view from above the pitch transition. We re going to do a pitch transition or change.

The roof plane goes from one pitch to a lower pitch. Pitch transitions are a common roof detail. Just simple 3d animated digital instructions on how to install transition trim on a masterrib metal roof. The other shows a view underneath the pitch transition strip flashing taken from the lower flatter pitch of roof.

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. This is a fairly common roof detail. 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. A roof pitch transition is a line in the roof plane that changes pitch.

Low slope metal roofs require less material which reduces the overall load on the building s structure. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. See the illustration below.
