The smallest pitch of a roof is 1412 which translates to 14 inch rise to 12 inches of run. Roofing with exposed fasteners and lapped seams with sealant can go lower 12.
Just like other metal roofs the minimum pitch for a corrugated metal roof largely depends on the profile of the roof.
That means there is at least 3 of vertical rise to the roof slope for every 12 it goes back horizontally. Because of the shallow height of the undulating ridges of the 5V and corrugated profiles and the use of exposed metal fasteners to. As a result this may cause the water to leak through the lapping roof sheets and into the building below. The minimum pitch for metal roof shingles and lapped non-soldered panels is 312.
