Most residential metal roofs require at least a 3 12 roof pitch and have no maximum roof pitch.

Minimum roof pitch metal roof.

The minimum pitch for metal roofing varies depending on the profile of the metal. Minimum required roof slope for roofing materials. That means there is at least 3 of vertical rise to the roof slope for every 12 it goes back horizontally. 9 46 built up roof asphalt.

After that the miimum pitch for metal panels depending on the methods used to join the panels. 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. This means for every 12 horizontal units the roof must rise a minimum of 3 vertical units. The minimum pitch is typically 3 12 meaning the roof should rise 3 inches for every 12 inches of horizontal foot.
