Metal roofing underlayment separates metal roofing panels from the roof deck. It both protects a building from water during the roof installation process and acts as a secondary barrier from weather elements when a metal roof is complete. Metal roofing insulation has heat conducting and reflecting properties and serves as a vapor retardant which help to reduce energy costs.
