Standing Seam Metal Roof Slope Transition

This guide is does not cover some aspects of installation.

Standing seam metal roof slope transition.

Butyl sealant tape or tube sealant should be used under all z channel. This means that the minimum roof slope required for panels is 3 inches of rise per foot. Minimum slope requirements depending on the roof profile there are minimum roof slope requirements for each panel which need to be considered. By the way pitch is measured by picking any point on the roof place a level on it measure 12 out from that point this is called the run and then down to the roof surface from the bottom of the level this is called the rise to see how many inches the roof pitches over 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. 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. Standing seam trim details a brief guide to the various trims used for standing seam metal roofing as well as how they are installed. We require at least a 3 12 pitch for standing seam panels to ensure proper water drainage.

Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. The minimum slope for standing seam of roof systems shall be one quarter unit vertical in 12 units horizontal 2 percent slope. Roof pitch slope for reference standing seam metal roofing is not one size fits all. We re going to do a pitch transition or change.

As you can see from illustration the roof changes pitch at the porch from a 9 12 to a 3 12 pitch. 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.
