ABSTRACT:
A reroofing system and method for weatherproofing the metal panels which are attached to an existing roof deck by series of fasteners. A tape laminate formed of butyl rubber and unvulcanized EPDM is applied over the series of fasteners and over the seams formed by adjacent and overlapping panels to provide a weatherproof seal therefor. The butyl rubber has sufficient natural tackiness to secure the EPDM to its top surface and to secure the bottom surface of the tape to the metal panels. The tape laminate has an elongation of approximately 600% and thus is unaffected by panel and building movements. A coating of an acrylic paint may be applied over the tape laminate and remaining surfaces of the roof panels to increase the weatherproofing effectiveness thereof and to provide an aesthetically pleasing appearance.
