Existing metal roof had leaks across the building. Many commercial metal roofs are installed with exposed fasteners. As the roof ages, the metal fasteners will rust and the washers will deteriorate, creating roof leaks. Seam tape was applied to metal roof seams to create an expansion joint. A fibered silicone coating was applied to fasteners and seams before top coat application. Top coat was applied at 40 wet mils.
