Why Metal Roofs Fail
The metal is fine. The seams are the problem.
Metal roofs are among the most durable commercial substrates available. But every failure we see is at the seams, fasteners, and panel transitions — not in the metal panels themselves. Replacing an entire metal roof because its seams have failed is the most expensive possible solution to a targeted problem.
Silicone restoration addresses exactly those failure points — sealing every fastener, bridging every panel transition, and delivering a continuous watertight membrane over the entire surface.

Exposed fastener heads corrode, and EPDM backings degrade under UV — creating dozens or hundreds of individual leak points that patch cycles cannot keep up with.
Rust at panel edges, valley gutters, and seam joints migrates beneath the surface, compromising adhesion and accelerating structural deterioration if left untreated.
Metal roofs expand and contract significantly with temperature. Standard coatings crack and delaminate under this movement. Silicone accommodates it permanently.
Installation Process
From assessment to sealed — four steps.
Metal Roof Assessment
We inspect every seam, fastener, panel transition, and penetration. Thermal imaging identifies moisture intrusion beneath the metal surface.
Surface Preparation
Rust is treated, panels power-washed, all fastener heads sealed, and critical seams reinforced with fabric-embedded silicone. Every active leak source is eliminated.
Silicone Membrane Application
Full-surface silicone coating spray-applied over the metal substrate, bridging all panel transitions, seams, and fastener patterns into a continuous watertight membrane.
Inspection & Warranty
Post-installation inspection confirms complete coverage. Manufacturer warranty issued for 10, 20, or 30 years. System recoatable at warranty end.
Technical Specifications
Engineered for metal. Built to move with it.
Metal substrates demand a coating that can accommodate thermal expansion without cracking. Silicone's flexibility is the fundamental reason it outperforms every alternative on metal roofing.
Acrylic coatings cure rigid and crack under metal thermal cycling. Silicone remains flexible at -65°F and up to 300°F continuous service — matching the full temperature range metal roofs experience in any US climate zone.
Metal Roof Restoration FAQ
Common questions about metal roof restoration
Yes. We treat active rust with rust-inhibiting primer before applying silicone. The coating encapsulates the treated rust and prevents further oxidation. Structural rust (compromising panel integrity) requires panel replacement before coating.
Yes. Silicone is highly flexible and maintains adhesion through the thermal movement cycles that metal roofs experience seasonally. This is one of the reasons silicone outperforms acrylic on metal substrates.
Fastener-pattern leaks are one of the most common metal roof restoration scenarios. We seal every fastener head as part of surface prep, then apply a full silicone membrane over the entire surface. This is significantly more cost-effective than re-fastening or re-roofing.
We restore standing seam, R-panel, corrugated, barrel vault, and Galvalume metal roofing systems. The primary qualification is panel structural integrity — panels must be sound enough to support the coating load.
Yes. A full silicone membrane significantly dampens rain noise on metal roofing — a common secondary benefit our clients appreciate, especially in occupied facilities.
