Coating Solutions for Metal Roofs
Standing seam, R-panel, and corrugated metal roofs move with temperature changes and commonly leak at fasteners, horizontal seams, end laps, penetrations, and transitions. Correct the metal and detail failures before selecting an acrylic or silicone weathering surface.

Acrylic or silicone?
Choose an option to see its layers in order. Our team checks the roof, primer, coating thickness, and product amount before the project starts.
Common roof concerns
- Rust or corrosion at cut edges, fasteners, and damaged coatings
- Backed-out fasteners, failed washers, and loose closures
- Open horizontal seams, end laps, curbs, and penetrations
Field preparation
- Replace loose fasteners and failed closures
- Remove rust and prime exposed metal
- Three-course seams, laps, and penetrations
Release checkpoints
- Rust is stable beneath Black Primer
- Every fastener is sealed
- Movement joints remain able to cycle

Answers before the roof brief.
Use these answers for planning, then follow the current written specification for the project.
Can an existing Metal roof be coated?+
A Metal roof may qualify when the assembly is identified, sound, dry, repairable, properly prepared, and proven compatible through project-specific testing. Wet or unsound areas must be addressed before coating.
What preparation does Coating Solutions for Metal Roofs require?+
Preparation depends on the exact substrate and condition. Inspection, moisture review, cleaning, drying, repairs, detail work, and representative adhesion testing come before the final primer and coating sequence.
How is the material quantity calculated?+
The estimator uses measured roof area, detail length, system family, planning term, and a waste or texture allowance. Actual ordering must follow current coverage rates, specified film build, surface profile, and field verification.
Which technical documents belong in the project file?+
Start with the system specification, then include the current product data, safety data, applicable detail drawings, approvals, warranty requirements, and any written project-specific instructions.
When should the technical team review the roof?+
Request a review whenever the substrate is uncertain, moisture or drainage is a concern, adhesion results vary, prior coatings are present, warranty coverage is planned, or field conditions differ from the published system.
