Our 5-Step Professional Painting Process
Professional metal roof painting requires specific steps to ensure longevity. Cutting corners leads to peeling bubbling and premature failure.
- Power Washing and Debris Removal
We use 3000+ PSI pressure washers to remove dirt oxidation and loose paint. This step reveals any rust spots or damaged areas that need repair before painting begins. 24/7 Emergency Roof Repair.
- Rust Treatment and Priming
Exposed metal gets treated with rust converters that chemically transform iron oxide into a stable compound. We then apply zinc chromate primer to create a corrosion-resistant base layer.
- Sealing Fasteners and Seams
Roof penetrations and overlapping panels get sealed with polyurethane sealant. This prevents water infiltration and ensures the coating system remains intact through seasonal expansion cycles.
- Precision Application Techniques
We apply two coats of elastomeric coating using airless sprayers for even coverage. The first coat acts as a primer while the second provides the final color and protection. Each coat dries for 24 hours in optimal conditions.
- Final Inspection and Warranty
Our team inspects every square foot for missed spots drips or adhesion issues. We provide a 10-year warranty on workmanship and a 15-year warranty on coating performance.
