A defined section of metal roofing
The October 29 proposal marks one area for fastener replacement. The existing PBR roof panels would remain in place while work concentrates on the fasteners within that boundary.
New fasteners and sealing washers
The proposed method replaces old through-fasteners with oversized self-drilling fasteners fitted with new EPDM washers. Installation calls for the correct washer compression, careful handling of the panels and removal of metal shavings.
The repair proposal
The marked roof view and close-up photographs accompany the full proposal below. Panel replacement and whole-roof refastening would be separate projects.
