Minimum Roof Pitch Corrugated Metal

The minimum pitch for a standing seam metal roof is 1 4 or 3 inches rise to 12 inches run.

Minimum roof pitch corrugated metal.

Corrugated metal roofing has the same minimum pitch. The corrugated metal roof minimum slope is 5 degrees. Just like other metal roofs the minimum pitch for a corrugated metal roof largely depends on the profile of the roof. For the most part the minimum pitch for metal roof installations depends on what kind of material you are installing and the method in which the material is being fastened.

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. Corrugated roofing is a great material on traditional pitched roofs but it has severe limitations when the pitch gets below 5 degrees. The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. The minimum pitch for roll roofing is 2 12 or 2 inches rise to 12 inches run.

In most occasions a pitch of three in twelve is preferred but this should also take into consideration the manufacturer s recommendations as well the unique condition of the corrugated metal roof.
