Self-Adhering Membranes

Our Imperflex® membranes are self adhering for safe and convenient installation on residential roofs where roof slopes prevent the effective use of shingles, tile or metal. Self-adhering membranes require less equipment and eliminate the need for hot asphalt or an open flame during installation.
