FAQs
What makes a metal roof coating qualify for an ENERGY STAR rating?
To earn the ENERGY STAR label, a roof coating must meet strict solar reflectance and thermal emittance thresholds established by the U.S. Environmental Protection Agency. In practical terms, the coating has to reflect a significant percentage of the sun’s infrared radiation and quickly release any absorbed heat. ENERGY STAR–rated metal roof coatings typically contain specialized pigments and high-quality resins that keep the roof surface cooler, reduce heat transfer into the attic, and maintain these reflective properties for years—even under Lenoir City’s strong summer sun.
How much can an ENERGY STAR–rated coated metal roof save me on energy bills in Lenoir City?
Homeowners in Lenoir City commonly see 10–25 % reductions in summer cooling costs after applying a high-reflectivity ENERGY STAR coating. The exact savings depend on roof orientation, attic insulation, and HVAC efficiency, but a typical 2,000-sq-ft home can save $150–$300 per year. Because East Tennessee experiences hot, humid summers, the payback period for the coating is often 3–7 years, after which the energy savings become net profit for the rest of the coating’s 15- to 20-year service life.
Will an ENERGY STAR coating extend the life of my existing metal roof?
Yes. Besides lowering surface temperatures by up to 60 °F, the coating seals minor seams and fastener penetrations, halting rust and corrosion. Reduced thermal expansion and contraction cycles lessen metal fatigue, preventing premature panel or fastener failure. When properly applied, a premium ENERGY STAR coating can add 15 or more years to the service life of a well-maintained metal roof.
Can older metal roofs be coated, and what preparation is required?
Even roofs 20–30 years old can usually be coated, provided the substrate is structurally sound. Preparation involves power-washing to remove dirt, mildew, and chalking; spot-treating rust with a metal primer; tightening or replacing loose fasteners; and sealing seams with an elastomeric tape or mastic. A clean, dry, and rust-free surface ensures the ENERGY STAR coating bonds properly and delivers its full reflective and waterproofing benefits.
How does an ENERGY STAR–coated metal roof stand up to East Tennessee weather events?
The coatings we use are formulated for high UV exposure, heavy rain, and rapid temperature swings typical of the Cumberland Plateau and Tennessee Valley. Once cured, the elastomeric film remains flexible down to –20 °F and resists ponding water, hail impact, and wind-driven debris. Most products carry a 10- to 20-year manufacturer’s material warranty and meet UL 2218 Class 4 hail and ASTM D6083 weathering standards, ensuring long-term performance in Lenoir City’s climate.
What is the installation timeline and disruption level for homes or businesses in Lenoir City?
A professional crew can clean, prep, and coat an average 3,000-sq-ft metal roof in two to three days, weather permitting. Because the process is done entirely from the rooftop, there is minimal disturbance to occupants—no odors inside, no tearing off old roofing, and very little noise compared with full roof replacement. Most coatings are water-based and low-VOC, so they are safe for surrounding landscaping and pets. After a 24-hour cure period, the roof is fully trafficable and back to normal use.
