High-performance Coatings
High-performance Coatings | Metal Roofing | Roofing
Looking for a roof that outlasts harsh weather, slashes energy bills, and still turns heads from the curb? HEP’s high-performance coatings transform metal roofing into a formidable shield, sealing every seam with advanced polymers that resist UV rays, corrosion, and color fade. The result is a sleek, low-maintenance surface that reflects heat in summer, locks warmth in winter, and keeps leaks at bay year-round—backed by warranties measured in decades, not years.
Our specialized application process means faster installation, minimal disruption, and an eco-friendly footprint. Whether you’re protecting a historic farmhouse or a cutting-edge commercial build, HEP delivers custom colors, textures, and finishes that elevate metal roofing from functional to phenomenal—all while adding real value to your property and peace of mind above your head.
FAQs
What are high-performance roof coatings and how do they benefit metal roofs?
High-performance roof coatings are advanced elastomeric or acrylic membranes engineered to adhere tightly to metal panels, creating a seamless, watertight barrier. They stop leaks by sealing fasteners and seams, prevent corrosion by isolating the metal from moisture and oxygen, and reflect up to 85-90 % of solar heat, lowering roof-top temperatures by as much as 50 °F. The result is extended roof service life—often 10–20 additional years—reduced cooling costs, and minimized maintenance compared with an uncoated metal roof.
How long does a high-performance coating last on a metal roof?
Service life depends on film thickness, coating chemistry, roof preparation, and climate, but most premium systems carry 10-, 15-, or 20-year manufacturer warranties. With routine inspections and an inexpensive re-coat at the end of the warranty term, many building owners keep the same coated metal roof functional for 25–30 years or more before a total replacement is ever considered.
Can a coating be applied to rusty or aging metal roofs?
Yes. A key advantage of coating systems is their ability to rescue aging metal panels. Our process starts with power-washing to 2,500–3,500 psi, followed by mechanical removal of loose rust and the application of a rust-inhibitive primer. Fasteners are tightened or replaced, seams are reinforced with polyester mesh or butyl tape, and only then is the finish coat sprayed or rolled. Once cured, the coating encapsulates remaining surface oxidation and stops further corrosion.
Will a roof coating improve my building’s energy efficiency?
Absolutely. White or light-colored reflective coatings possess solar reflectance (SR) values of 0.80 or higher and emissivity (E) values above 0.85, meaning they bounce most solar radiation back into the atmosphere and quickly re-emit any absorbed heat. Independent studies by the U.S. DOE show cool roofs can cut summertime HVAC consumption 10–30 %, decrease interior temperatures 5–8 °F in non-air-conditioned spaces, and lower peak-demand charges, offering paybacks as short as 3–5 years.
What maintenance is required after a coating is installed?
Compared with exposed metal, coated roofs are low maintenance. We recommend visual inspections each spring and fall, removal of debris from gutters and valleys, and spot cleaning with a mild detergent if heavy dirt accumulates. Any new penetrations (HVAC curbs, antennas, etc.) should be flashed with compatible sealant. If small chips or cuts occur, touch-up can be done with brush-grade coating. Following these steps preserves warranty coverage and maximizes the coating’s lifespan.
Is the installation process disruptive to daily operations?
Not at all. Coatings are applied in place, so there is no tear-off noise, dust, or disposal. Crews work from the roof surface with portable spray rigs or rollers, allowing your business to remain open. Because coatings are water-based and low-VOC, odor is minimal and safe for occupied facilities such as schools, hospitals, and warehouses. Typical projects cover 7,000–10,000 sq ft per day, enabling most roofs to be completed in a few days without interrupting normal activities.
