FAQs
What exactly is a high-performance coating for metal roofing?
A high-performance coating is an advanced liquid or spray-applied membrane—typically an elastomeric acrylic, silicone, or polyurea—designed to bond tightly to metal panels. Once cured, it creates a seamless, flexible, UV-stable barrier that resists rust, ponding water, temperature cycling, and chemical exposure. The coating effectively upgrades an existing or new metal roof with enhanced durability, energy savings, and longer life at a fraction of full replacement cost.
Why are these coatings beneficial for metal roofs in McDonald’s climate?
McDonald experiences hot, humid summers, periodic hail, and rapid freeze-thaw cycles in winter. High-performance coatings reflect up to 85% of solar heat, keeping attic temperatures lower and reducing HVAC load during peak summer months. Their elastomeric nature stretches and contracts with the metal, preventing cracks during temperature swings. They also seal fastener heads and seams against wind-driven rain and hail, which are common in western Pennsylvania.
How long will a coated metal roof last, and what warranties are available?
When properly prepped and coated, a metal roof can gain 15–20 additional service years. Most manufacturers back their systems with renewable warranties of 10, 15, or even 20 years, provided the installer is certified and maintenance guidelines are followed. After the initial term, the roof can often be washed, re-top-coated, and re-warranted for extended life without major tear-off.
Can my existing metal roof be coated, or do I need a new roof first?
In most cases, your current roof can be rejuvenated. We start with a detailed inspection to locate rust, loose fasteners, or damaged panels. Minor repairs are made, rust is treated with a primer, and all seams/penetrations are sealed before the coating is applied. Only roofs with severe structural damage or widespread panel failure would need replacement before coating.
What is the installation process and how much downtime should I expect?
A typical McDonald commercial roof (20,000–30,000 sq ft) can be cleaned, prepped, and coated in 3–5 working days, weather permitting. Because the system is applied over the existing roof, there is no noisy tear-off, and most businesses stay fully operational. The coating is usually dry to the touch within a few hours and fully cured within 24–48 hours.
Are high-performance roof coatings environmentally friendly and low-maintenance?
Yes. By restoring rather than replacing a roof, coatings divert tons of metal from landfills. Most formulations are low-VOC and ENERGY STAR® approved, lowering your building’s carbon footprint through reduced cooling demand. Maintenance is straightforward: annual inspections, gutter cleaning, and spot repairs if punctures occur. No special cleaners or solvents are needed—just periodic washing with a mild detergent and water.
