Standing Seam Metal Roof Slope Transition

Minimum slope requirements depending on the roof profile there are minimum roof slope requirements for each panel which need to be considered.

Standing seam metal roof slope transition.

Standing seam trim details a brief guide to the various trims used for standing seam metal roofing as well as how they are installed. This guide is does not cover some aspects of installation. We require at least a 3 12 pitch for standing seam panels to ensure proper water drainage. This means that the minimum roof slope required for panels is 3 inches of rise per foot.

Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. As you can see from illustration the roof changes pitch at the porch from a 9 12 to a 3 12 pitch. We re going to do a pitch transition or change. Roof pitch slope for reference standing seam metal roofing is not one size fits all.

The minimum slope for standing seam of roof systems shall be one quarter unit vertical in 12 units horizontal 2 percent slope. Low slope metal roofs require less material which reduces the overall load on the building s structure. 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. Butyl sealant tape or tube sealant should be used under all z channel.

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. 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.
