Ice Dam Prevention
Applying a layer of ice guard or ice and water shield can prevent ice dams. It should reach around two feet up the roof from the upper edge of the overhang. You can add an extra layer of ice guard if needed.
Underlayment Options
Like with shingle roofs, there are various underlayment options for metal roofing. A layer of felt or building paper will prevent leaks in the attic and provide added insulation. Your local building code may require a specific weight of felt paper. Metal roofing underlayment requires an extra slip sheet layer, which is usually a red rosin paper. It will prevent the metal from sticking to the felt paper during installation.
Another option is polymer underlayment sheets. They are thinner and easier to use than layers of tar paper and rosin paper. The sheets are durable, waterproof and slick enough to replace both underlayment layers.
Proper Installation
Metal roofing underlayment installation is pretty straightforward. Your contractor will lay down strips of felt paper or polymer underlayment horizontally across the roof, overlapping the layers by at least four inches. They will staple each strip at the ends and generously overlap the underlayment where two parts of the roof meet in the valley.
