Cooling Costs | Metal Roofing | Roofing | Hixson
Summer in Hixson can turn an ordinary shingle roof into a giant heat sink, but HEP’s metal roofing systems reflect the sun’s rays instead of absorbing them. Engineered with high-performance coatings and precision-locked seams, our panels create a thermal barrier that can trim your cooling bills by up to 25% while giving your home a crisp, modern look that lasts for decades.
Backed by local crews who understand Tennessee’s climate, we install each roof with superior ventilation, tight fastening, and a transferable warranty that adds real value to your property. Choose HEP to enjoy quieter rainstorms, lower maintenance, and the year-round comfort that comes from owning a roof designed to beat the heat—so you can spend less on energy and more on what matters.
FAQs
How does a metal roof help lower cooling costs in Hixson’s hot summers?
Metal roofing panels are naturally reflective, bouncing a significant portion of the sun’s radiant energy back into the atmosphere instead of absorbing it into your attic. Many modern metal roofs are coated with specialized “cool roof” finishes that enhance this reflectivity and also re-emit absorbed heat quickly. In a climate like Hixson, where summer temperatures routinely climb into the 90s, this can reduce attic temperatures by 20–40°F, which translates to less workload on your air-conditioning system and energy savings of 10-25% on cooling bills.
What roof color or finish is best for maximizing energy efficiency?
For optimal energy savings, choose lighter colors such as white, light gray, beige, or specialized cool-roof pigments. These finishes can reflect 60–70% of solar radiation. If you prefer darker tones for aesthetic reasons, select a metal panel with an ENERGY STAR-rated coating; advanced infrared-reflective pigments allow even dark colors to reflect more heat than conventional paint, retaining attractive curb appeal without sacrificing efficiency.
Will adding insulation under a metal roof improve cooling performance further?
Yes. A properly installed radiant barrier or rigid foam insulation beneath the metal roofing adds an extra layer of thermal resistance, preventing residual heat from entering the living space. Combining reflective metal panels with R-19 to R-38 attic insulation can cut overall HVAC energy use by up to 30% compared to an asphalt-shingle roof with minimal insulation.
How long does a cool-roof metal system last compared to traditional shingles?
Quality steel or aluminum roofs in Hixson typically last 40–70 years, far outliving asphalt shingles that need replacement every 15–20 years. The baked-on cool-roof coatings resist fading, cracking, and peeling even under intense UV exposure. Longer lifespan means you’ll benefit from decades of lower cooling costs and avoid multiple tear-off and re-roof cycles, reducing long-term ownership costs.
Are there local or federal incentives for installing an energy-efficient metal roof?
Homeowners in Hixson may qualify for a federal tax credit of up to 30% of material costs (subject to annual limits) when installing ENERGY STAR-certified metal roofs. Tennessee Valley Authority (TVA) programs periodically offer rebates or low-interest financing for energy-efficient upgrades; check the latest TVA eScore or Home Uplift initiatives. Some insurance companies also provide premium reductions because metal roofs are fire-resistant and durable.
How does ventilation work with metal roofing to keep attics cooler?
Proper ventilation pairs intake vents (soffit or eave) with exhaust vents (ridge or gable) to create a continuous airflow path beneath the roof deck. Metal roofing systems are typically installed with raised seams and vented ridge caps that allow hot air to escape naturally. This exhaust cycle removes moisture and heat, keeping attic temperatures closer to outside ambient levels and ensuring the reflective benefits of the metal panels aren’t undermined by trapped hot air.
