Repairing metal roofs: fastener and gasket replacement on screw-down panels, seam and flashing work, oil-canning, and why sealant-only fixes fail.
What Is Metal Roof Repair?
Metal roof repair divides by fastening system. On exposed-fastener (screw-down) roofs, the dominant failure is the fasteners themselves: thousands of gasketed screws whose neoprene washers UV-degrade, crack, and lose compression as panels expand and contract daily — leaks then follow the screw lines. The durable repair replaces fasteners with oversized screws and new washers across the roof, not dabs of caulk on the leakers, because every washer on the roof is the same age. On standing seam roofs, the panel field is fastener-free, so leaks concentrate at flashings, penetrations, end laps, and ridge details, and repairs are detail work demanding familiarity with the specific seam profile. Cross-cutting facts: sealant chemistry matters (butyl and polyurethane products adhere to metal long-term; general-purpose silicone often does not), dissimilar-metal contact corrodes (copper wash over galvanized steel, for instance), and rust at scratches and cut edges is arrested early with rust-inhibiting treatment and touch-up. Oil-canning — visible waviness in flat panel areas — is cosmetic, not a defect requiring repair.
Important Distinction
Note: Most metal roof leaks are fastener and flashing failures, not panel failures: on screw-down roofs the gasketed screws weather and back out on a schedule, and re-fastening — not caulking each screw — is the durable fix.
