Minimum metal roof slope depends on the roof profile building design climate and site location.

Because of the shallow height of the undulating ridges of the 5v and corrugated profiles and the use of exposed metal fasteners to screw the metal to the roof deck they are limited to a slope that will shed rain quickly. Low slope metal roofs require less material which reduces the overall load on the building s structure.
