Metal Roof Pitch Change

Panels joined with an applied lap sealant can go as low as 12.

Metal roof pitch change.

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. The pitch is measured in inches of vertical rise per foot of horizontal run and the 5v crimp profile shown above requires a minimum slope of three in twelve or 3 12 3 inches vertically per 12 inches horizontally. After that the miimum pitch for metal panels depending on the methods used to join the panels. There are some standing seam metal roofing options available from atas and other manufacturers that can be installed on a roof with pitch of 1 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. 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 pitch for metal roofing varies depending on the profile of the metal.

Profile in the context of metal roofing means the shape that the sheet of metal is bent into to form the panels. 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. The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12.
