Standing Seam Metal Roof Slope Transition

Low slope metal roofs require less material which reduces the overall load on the building s structure.

Standing seam metal roof slope transition.

See our installation guide for more info. This means that the minimum roof slope required for panels is 3 inches of rise per foot. 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.

Butyl sealant tape or tube sealant should be used under all z channel. We require at least a 3 12 pitch for standing seam panels to ensure proper water drainage. 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. As you can see from illustration the roof changes pitch at the porch from a 9 12 to a 3 12 pitch. 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. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12.

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. The minimum slope for standing seam of roof systems shall be one quarter unit vertical in 12 units horizontal 2 percent slope.
