FAQs
What are reflective roof coatings and how do they work on metal roofs?
Reflective roof coatings are high-performance acrylic, silicone, or hybrid liquids that are rolled or sprayed onto an existing metal roof. Once cured, the coating forms a seamless, elastomeric membrane that has two key properties: high solar reflectance (it bounces away 70-90 % of the sun’s rays) and high thermal emittance (it quickly releases any heat it does absorb). On a metal roof this keeps surface temperatures 40-50 °F cooler, reduces thermal expansion and contraction that can loosen fasteners, seals minor seams and fastener heads, and provides an additional water-tight layer over the original panels.
What specific benefits do reflective coatings provide in Sequatchie’s climate?
Sequatchie County experiences hot, humid summers, strong UV exposure, and occasional winter freezes. A reflective coating helps: • Lower attic and indoor temperatures during long summer afternoons, reducing air-conditioning run-time by 10-30 %. • Block UV radiation that fades paint and accelerates corrosion on uncoated metal. • Control condensation on the underside of panels in spring and fall, minimizing the chance of rust from trapped moisture. • Moderate daily temperature swings, limiting metal movement that can stress seams and gaskets. • Extend the roof’s service life 10-20 years, postponing a costly tear-off.
Can a reflective coating be applied to any metal roof, and what preparation is required?
Most metal systems—standing-seam, R-panel, corrugated, and even older galvanized or Galvalume® roofs—are good candidates as long as the panels are structurally sound. Typical preparation steps include: 1. Detailed inspection to locate loose fasteners, lifted seams, or rusted areas. 2. Mechanical tightening or replacement of fasteners and repair of damaged panels. 3. Pressure-washing (2,500–3,500 psi) with a biodegradable detergent to remove chalk, dirt, and mildew. 4. Spot-priming any rust with a rust-inhibitive metal primer. 5. Sealing seams, penetrations, and end-laps with a compatible butyl or silicone mastic. 6. Application of one to two coats of the reflective coating by airless sprayer or roller at the manufacturer’s specified mil thickness.
How long will a reflective coating last on my metal roof, and what maintenance is required?
Premium acrylic or silicone systems carry warranties of 10, 15, or 20 years. Longevity depends on film thickness, roof pitch, and exposure. Routine maintenance is simple: • Inspect the roof each spring and fall, clearing leaves and limbs from valleys and gutters. • Wash off heavy soil or pollen with a garden hose or low-pressure washer. • Reseal isolated cuts, sheet-metal modifications, or new penetrations with compatible mastic. • Plan a re-coat at about year 12–15 (or when reflectivity drops below 65 %) to reset the service-life clock without stripping the old coating.
Will a reflective coating lower my energy bills or qualify for incentives in Tennessee?
Yes. Oak Ridge National Laboratory studies show cool coatings can cut summertime cooling costs 15–30 % in the Tennessee Valley. Many property owners see a 3-7 year payback. In addition, ENERGY STAR®–listed roof coatings installed in 2023-2032 may qualify for the federal Residential Energy Efficient Home Improvement Credit (25C)—30 % of product and labor costs up to $1,200 per year. Some local utilities, including TVA partners, periodically offer per-square-foot rebates for cool-roof installations; we help customers file the paperwork when programs are active.
How much does it cost to coat a metal roof in Sequatchie, and how does that compare to replacement?
Most commercial and residential projects fall between $1.50 and $4.00 per square foot installed, depending on roof size, the amount of rust repair or seam mastic needed, and the number of coats. By contrast, a full tear-off and replacement of a metal roof typically ranges from $7 to $12 per square foot. Because coatings are applied over the existing roof, there is little to no landfill cost, minimal business interruption, and no exposure of the interior to weather during the work.
