This is a self- adhering polymer modified bitumen sheet that is required by Minnesota Code to be applied to the bottom eves of the roof past the interior wall 24 and up any valleys on any heated or cooled structures. It adheres to the decking, so that if you get an ice dam pushes water under the shingles, it will not allow the water to seep into your attic.
