Minimum Pitch On A Metal Roof

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

Minimum pitch on a metal roof.

The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. Minimum pitch for corrugated metal roof corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch. Just like other metal roofs the minimum pitch for a corrugated metal roof largely depends on the profile of the roof. It is the recommended slope as there is no guarantee if you opt for flatter pitch than this.

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. 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. Corrugated metal roofing has the same minimum pitch. 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.

The minimum slope for lapped non soldered seam metal roofs without applied lap sealant shall be three units vertical in 12 units horizontal 25 percent slope.
