Roof Pitch For Metal Roof

Profile in the context of metal roofing means the shape that the sheet of metal is bent into to form the panels.

Roof pitch for metal roof.

The minimum pitch for metal roof shingles and lapped non soldered panels is 3 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 minimum pitch is typically 3 12 meaning the roof should rise 3 inches for every 12 inches of horizontal foot. The metal roof minimum slope doesn t stray far from other building with different material.

That is a 14 degree angle. That means there is at least 3 of vertical rise to the roof slope for every 12 it goes back horizontally. Panels joined with an applied lap sealant can go as low as 12. Metal roof slope is expressed by a ratio indicating the roof pitch which notes the vertical rise of the roof in inches for every 12 inches the roof runs horizontally in other words dividing the vertical rise and its horizontal span.

The profile refers to the shape the metal sheets take when they bend to form panels. 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.
