FAQs
What are reflective cool-roof coatings and how do they work on metal roofs?
A reflective cool-roof coating is a high-performance, elastomeric paint system that is engineered to reflect a large percentage of the sun’s ultraviolet (UV) and infrared (IR) radiation. When applied to a metal roof, the coating forms a seamless, bright white or light-colored membrane that bounces heat away instead of absorbing it. This keeps the metal panels—and the building’s interior—significantly cooler, lowers HVAC runtimes, and reduces thermal expansion and contraction cycles that can fatigue a roof over time.
How much can I expect to save on energy bills in Collegedale by installing a cool-roof coating?
Actual savings depend on your building’s insulation, HVAC efficiency, and occupancy patterns, but studies in climates similar to Collegedale’s humid subtropical zone show 10–30 % reductions in summertime cooling costs. Roof surface temperatures can drop by 40–60 °F, which translates into noticeably lower indoor temperatures and smaller peak-demand loads on air-conditioning equipment. Many local clients report a simple payback window of three to six years based on utility savings alone.
Is my existing metal roof a good candidate for a reflective coating?
Most standing-seam and R-panel metal roofs in fair or better condition can be coated. The key requirements are that the panels are structurally sound, fasteners are tight, and there is no widespread rust perforation. Before coating, we perform a detailed inspection in Collegedale to identify any loose seams, failing fasteners, or localized corrosion. Minor repairs are completed first, ensuring the coating adheres properly and delivers its full 10- to 20-year service life.
What is involved in the application process and how long will it take?
1. Roof Evaluation & Moisture Scan 2. Power-washing and Rust Mitigation 3. Seam/Fastener Sealing with Butyl or Polyurethane Mastics 4. Primer Application (if needed) 5. Spray or Roll Application of Base Coat 6. Final Reflective Topcoat A typical 10,000-sq-ft commercial roof in Collegedale can be completed in two to four days of favorable weather, with minimal disruption to operations. Because we use low-odor, water-based acrylics or silicone products, most facilities remain fully operational throughout the project.
How long do cool-roof coatings last on metal roofs and what maintenance is required?
High-quality acrylic or silicone coatings carry warranties of 10, 15, or even 20 years when installed by a certified applicator. Longevity is tied to film thickness and proper prep work. Routine maintenance is straightforward: annual visual inspections, clearing of debris from gutters and valleys, and spot touch-ups if mechanical damage occurs. Periodic cleaning (every 3–5 years) with a mild detergent helps maintain peak reflectivity.
Are there rebates or incentives available in Collegedale or Tennessee for reflective roof coatings?
Yes. The Tennessee Valley Authority (TVA) periodically offers custom incentives for energy-saving roof projects through its EnergyRight program. In addition, reflective coatings can qualify for the federal Commercial Building Energy Efficient Tax Deduction (Section 179D) or the 30 % Energy-Efficient Home Improvement Credit (IRC 25C) for certain residential properties. We help Collegedale customers document reflectivity values (Solar Reflectance Index ≥ 82 for low-slope roofs) to maximize eligibility and can supply specification sheets for any local permit or utility rebate application.
