Roof Pitch For Metal Roof

The traditional metal roof types such as 5v crimp shown above and corrugated are rated by the manufacturers for use down to a 3 12 pitch three inches of vertical rise for every foot of horizontal run.

Roof pitch for metal roof.

The profile refers to the shape the metal sheets take when they bend to form panels. That means there is at least 3 of vertical rise to the roof slope for every 12 it goes back horizontally. Profile in the context of metal roofing means the shape that the sheet of metal is bent into to form the panels. Panels joined with an applied lap sealant can go as low as 12.

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. The metal roof minimum slope doesn t stray far from other building with different material. Most residential metal roofs require at least a 3 12 roof pitch and have no maximum roof pitch. The minimum pitch is typically 3 12 meaning the roof should rise 3 inches for every 12 inches of horizontal foot.

The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. The minimum pitch for metal roofing varies depending on the profile of the metal.
