Can you put metal roof on flat roof.

Low slope metal roofs require less material which reduces the overall load on the building s structure. 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. Most codes now allow no more than two layers of roofing before requiring a complete tear off. So if your roof has two layers it may require a complete tear off even though steel is lighter than asphalt.
