Reflective Coatings
Reflective Coatings | Metal Roofing | Roofing | Allardt
Imagine a roof that deflects the Tennessee sun, slashes cooling costs, and still looks sharp decades down the line—HEP’s reflective coatings make it happen for Allardt homes and businesses. Our specialized formula bonds seamlessly to new or existing metal roofing, bouncing away up to 85 % of solar heat while sealing out rust, leaks, and the relentless Appalachian humidity. The result is a cooler interior, a quieter rainstorm, and an exterior finish that keeps its gloss long after ordinary paint has faded.
Every project starts with a free on-site assessment from our Allardt team, followed by meticulous surface prep and a spray-on application that cures fast and resists peeling, chalking, and UV breakdown. Whether you’re protecting a farmhouse, retail space, or industrial facility, HEP delivers a roof that works as hard as you do—saving energy today and safeguarding your investment for years to come.
FAQs
What are reflective roof coatings and how do they work on metal roofs?
Reflective roof coatings are liquid-applied membranes made from acrylics, silicones, or polyurethanes that cure into a seamless, rubber-like layer over existing metal panels. They contain bright white or aluminum pigments with high solar reflectance and thermal emittance. By bouncing away a large portion of the sun’s infrared and ultraviolet rays, they keep the metal surface cooler, slow heat transfer into the building, and protect the roof from expansion-contraction stress, oxidation, and UV degradation.
What benefits can Allardt property owners expect from applying reflective coatings to their metal roofs?
• Energy savings: With daytime highs that often reach the 90s in an Allardt summer, coatings can lower rooftop temperatures by 30–50 °F and cut cooling costs 10–25 %. • Extended roof life: The coating shields the metal from rust, hail scuffs, and thermal cycling, adding 10–20 years of service life. • Leak prevention: Because the coating is seamless and elastomeric, it bridges small gaps around fasteners and seams. • Comfort & HVAC relief: Reduced attic and plenum temperatures translate to more stable indoor comfort and less wear on air-conditioning equipment. • Environmental benefits: Lower energy demand means fewer greenhouse-gas emissions and eligibility for cool-roof utility incentives when available.
How long does a reflective coating last on a metal roof, and when will I need to recoat?
Longevity depends on the coating chemistry and film thickness. High-quality silicone or urethane systems applied at 20–30 mils typically last 15–20 years before a recoat is required. Premium acrylics average 10–12 years. Routine inspections (once in spring and once in fall) and simple maintenance—such as clearing debris and touching up any damaged spots—help the coating reach its full life expectancy.
Will a reflective coating really lower my energy bills in Allardt’s climate?
Yes. TVA utility studies in the Upper Cumberland region show that cool roofs can reduce summertime HVAC run times by 10 % or more. In a 10,000 ft² commercial building in Allardt, that can translate to $0.12–$0.18 per square foot in annual electricity savings, depending on insulation levels and occupancy schedules. Residential homeowners generally see attic temperatures drop 15–25 °F, which eases demand on heat pumps and window units during peak hours.
Can reflective coatings fix leaks or rust on my existing metal roof?
Coatings are excellent preventive barriers but they are not structural repairs. Minor pinholes, small seams, and isolated surface rust can be treated with rust-inhibiting primer, reinforced mesh tape, and then coated to stop future corrosion and water intrusion. However, severely rusted panels, loose fasteners, or areas with standing-water damage must be repaired or replaced before the coating is applied. A professional roof assessment will identify and correct these issues first to ensure the coating adheres properly and performs as intended.
What is the installation process and how long does it take to coat an average metal roof in Allardt?
1. Inspection & repairs: A certified crew walks the roof, tightens fasteners, replaces failed gaskets, and primes rusty spots. 2. Cleaning: The roof is pressure-washed (2,500–3,000 psi) to remove dirt, mildew, and chalk. 3. Detailing: Seams, penetrations, and gutters receive mesh-reinforced flashing grade coating. 4. Application: The field coating is sprayed or rolled in one or two passes to the specified mil thickness. 5. Final inspection: Film thickness and adhesion are verified before issuing the warranty. For a typical 5,000 ft² metal roof, the entire process takes 2–3 days of on-site work, weather permitting. Larger commercial roofs may require a week. Because the system is low-odor and low-VOC, businesses and homeowners can usually remain operational during the project.
