Metal roof coating and rust restoration brings an old standing seam or R-panel roof back without pulling a single panel. On commercial and industrial buildings in South Seaville, NJ, the metal itself is usually fine. The trouble is at the fasteners, the laps and anywhere red rust has started.
Fasteners are the first thing we look at. Screw washers dry out and crack over the years, and every backed-out screw is a leak path. Our crew replaces or oversizes failed fasteners, then caps each one with a brushed-in sealant. Horizontal laps and end laps get fabric and a base coat.
Rust gets wire-brushed or power-tooled down to a stable surface, then treated with a rust-inhibitive primer. Skipping this step is why some coated metal roofs start bleeding orange through the top coat within a few years.
The field coat is usually acrylic or silicone, sprayed to spec thickness. It seals the laps, covers the rust and turns the roof reflective. Metal roof coating in South Seaville, NJ is often the most cost-effective restoration we do, because the panels stay and the building never opens up. See also roof seam and fastener sealing.
