Energy-efficient Coatings | Metal Roofing | Roofing | Powell
When Powell’s summer sun beats down, HEP’s energy-efficient coatings turn your roof into a hardworking shield, bouncing away heat instead of soaking it in. Our specialized formulas are engineered for superior reflectivity, helping to keep interior temperatures stable, reduce HVAC strain, and trim energy bills month after month. You’ll notice the difference in comfort, and your wallet will notice it, too.
Pair those high-performance coatings with our precision-installed metal roofing and you get the best of both worlds: sleek curb appeal, decades of corrosion-resistant durability, and an eco-friendly barrier that stands up to hail, wind, and UV rays. Backed by local expertise and industry-leading warranties, HEP makes it easy for Powell homeowners to upgrade once and enjoy lasting peace of mind.
FAQs
What are energy-efficient coatings for metal roofs and how do they work?
Also called "cool roof" or "reflective" coatings, these liquid membranes are applied to existing or new metal panels to create a seamless, UV-stable surface. High levels of solar reflectance and thermal emittance bounce sunlight away and release absorbed heat quickly, keeping the roof surface—and the attic below—significantly cooler than an uncoated roof. In Powell’s mixed climate, this reduces summer cooling loads and limits thermal expansion that can stress fasteners and seams.
How much can I save on energy bills in Powell with a coated metal roof?
Actual savings depend on roof size, insulation levels, HVAC efficiency, and usage patterns, but ENERGY STAR® testing shows reflective metal coatings can lower roof surface temperatures by 50–60 °F and cut summertime cooling costs by 10–25 %. Homeowners in Powell typically report annual utility savings of $0.10–$0.25 per square foot of roof area. Commercial buildings with large, low-slope metal roofs often see payback in 3–7 years through reduced energy consumption alone.
Can energy-efficient coatings withstand Powell’s freeze–thaw cycles, hail, and high winds?
Yes. The premium acrylic and silicone formulations we install remain flexible from –40 °F to 180 °F, so they expand and contract with the underlying metal without cracking. They are Class A fire-rated and have been third-party tested to ASTM D522 for cyclic movement and ASTM D6083 for weathering. Added elastomeric thickness also cushions hail impacts, and the seamless membrane helps prevent wind-driven rain from penetrating panel laps or fastener heads—an important advantage during Ohio’s spring storms.
Is my existing metal roof a good candidate for a reflective coating, or will it need replacement?
If your panels are structurally sound—no widespread rust perforation, major impact damage, or saturated insulation—a restorative coating is usually the most cost-effective option. We perform an on-site infrared scan and pull-test to be sure. Minor corrosion, loose fasteners, and isolated panel damage can be repaired as part of surface prep. If more than 25–30 % of the substrate is compromised, full replacement may make more sense. Our inspection and estimate are free, so you can compare both options.
What is the installation process and how long does it take for a typical building in Powell?
1) Inspection and moisture survey; 2) Power-washing at 2,500–3,000 psi; 3) Spot priming rusted areas; 4) Sealing seams, penetrations, and fasteners with high-solids mastic; 5) Spraying or rolling two coats of reflective finish to reach the manufacturer’s specified dry-film thickness (typically 18–30 mils). Weather permitting, a 3,000 ft² residence can be completed in 2–3 days; a 20,000 ft² commercial roof usually takes 4–6 working days, with minimal disruption because most work is done on the rooftop.
How do I maintain my coated metal roof and what warranties are available?
Maintenance is simple: visually inspect the roof each spring and fall, remove debris from valleys and gutters, and wash with a mild detergent every few years to keep the reflective surface clean. Small punctures can be re-sealed with brush-grade coating. The systems we install carry renewable manufacturer warranties of 10, 15, or 20 years depending on film thickness; optional maintenance agreements extend coverage and allow for a fresh topcoat at the end of the term, potentially doubling the roof’s service life to 40 years or more.
