Standing Seam Metal Roof Slope Transition

This guide is does not cover some aspects of installation.

Standing seam metal roof slope transition.

Roof pitch slope for reference standing seam metal roofing is not one size fits all. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. This means that the minimum roof slope required for panels is 3 inches of rise per foot. See our installation guide for more info.

As you can see from illustration the roof changes pitch at the porch from a 9 12 to a 3 12 pitch. The minimum slope for standing seam of roof systems shall be one quarter unit vertical in 12 units horizontal 2 percent slope. If you have a low slope application 3 12 or less is the industry standard it is important that you choose a mechanical system that is double locked. Minimum slope requirements depending on the roof profile there are minimum roof slope requirements for each panel which need to be considered.

We re going to do a pitch transition or change. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. Standing seam trim details a brief guide to the various trims used for standing seam metal roofing as well as how they are installed. 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.

Butyl sealant tape or tube sealant should be used under all z channel. Low slope metal roofs require less material which reduces the overall load on the building s structure.
