Minimum pitch for metal 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.

Minimum pitch on a metal roof. Corrugated metal roofing has the same minimum pitch. The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. 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. The minimum pitch for roll roofing is 2 12 or 2 inches rise to 12 inches run.

Just like other metal roofs the minimum pitch for a corrugated metal roof largely depends on the profile of 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. It is the recommended slope as there is no guarantee if you opt for flatter pitch than this. The corrugated metal roof minimum slope is 5 degrees.

The minimum slope for lapped non soldered seam metal roofs with applied lap sealant shall be one half unit vertical in 12 units horizontal 4 percent slope.
