Roswell Re-Cover

Initially, we removed the existing wall and curb flashing to substrate. We also removed the existing roof membrane to existing insulation. Then, we prepped the existing roof surface for the new roof installation. To being the product application, we mechanically attached 60mil TPO membrane to structural purlins over insulation boards. We then fully adhered TPO to vertical surfaces with solvent-based bonding adhesive. TPO pipe boots were then installed to all pipes penetrating the roof surface. TPO flashing strips were also installed to all curbs. We then flashed all penetrations, corners, and T-joints per the manufacturers specifications. All seams were welded between membranes with hot air welder and probed for accuracy. Membrane at edge metal was then terminated with pressure sensitive cover tape. Membrane at vertical surfaces were also terminated with termination bar. Finally, for the metal installation, we installed TPO coated drip edge at all draining edges. 24GA Kynar coated steel gravel stop was also installed at all non draining edges. lastly, new scuppers were installed.
