When you choose HEP for your home's energy-efficiency upgrade, you’re getting more than a roof—you’re investing in a high-performance shield that works year-round. Our metal roofing reflects the sun’s radiant heat instead of absorbing it, helping your attic stay cooler in summer and your HVAC system run less. The interlocking panels are built to withstand Tennessee’s toughest storms, resist corrosion, and last decades longer than conventional shingles, so you save money on both utilities and replacements while shrinking your carbon footprint.
Every HEP project is handled by factory-trained crews who install precision-engineered panels, premium underlayment, and high-performance ventilation designed specifically for your home. Backed by industry-leading warranties and HEP’s 24/7 customer support, you can relax knowing your investment is protected. Discover how effortlessly style, strength, and sustainability come together—schedule a free consultation today and feel the difference of a roof that pays you back from day one.
FAQs
How does a metal roof improve the overall energy efficiency of my home?
Metal roofing reflects a significant portion of the sun’s radiant heat instead of absorbing it, which keeps attic and indoor temperatures lower. Many metal panels are also designed with integral airspaces or cool-roof coatings that provide additional thermal breaks, further reducing conductive heat transfer into the building. This lower heat gain means your air-conditioning system runs less often, cutting energy consumption by 10-25% or more compared to dark asphalt shingles.
What is a “cool” metal roof and how is it different from a standard metal roof?
A cool metal roof is manufactured or coated with specialized pigments that increase solar reflectance (the ability to reflect sunlight) and thermal emittance (the ability to radiate absorbed heat). While bare or uncoated metal already reflects more heat than most traditional roofing materials, cool-roof finishes push the reflectivity into the 0.50-0.70 range and emittance into the 0.80-0.90 range, meeting ENERGY STAR® and Cool Roof Rating Council standards. The result is even greater reductions in rooftop temperatures and cooling loads.
Can metal roofing help save energy in cold climates, or is it only beneficial in hot regions?
Metal roofing offers energy benefits in all climates. In cold weather, properly installed metal roofs shed snow quickly, preventing ice dams that rob a home of heat through meltwater penetration. When paired with quality insulation and an optional under-roof vented airspace (known as a "cold roof" assembly), a metal roof helps maintain consistent indoor temperatures and reduces heat loss. Additionally, many metal systems are compatible with above-deck rigid foam or insulated panels, improving wintertime thermal performance even further.
Which colors or finishes provide the best energy savings on a metal roof?
Lighter colors such as white, beige, light gray, and pastel hues generally offer the highest solar reflectance values, leading to the greatest cooling-season energy savings. However, advances in cool-pigment technology allow even darker colors—charcoal, bronze, forest green—to achieve reflectance levels similar to lighter shades. When selecting a finish, look for products labeled with their Solar Reflectance Index (SRI). An SRI above 60 is often recommended for hot climates, while any increase in SRI can contribute meaningful savings.
Will the upfront cost of an energy-efficient metal roof pay off over time?
Although metal roofing typically costs 2-3 times more than standard asphalt shingles, its energy savings, durability, and low maintenance requirements provide an attractive life-cycle return. Homeowners often see 10-25% annual cooling-cost reductions, which can translate into thousands of dollars over the roof’s 40-70-year lifespan. Factor in lower insurance premiums (thanks to class-A fire and class-4 hail ratings), minimal repair costs, and higher resale value, and many installations recoup their premium within 10-15 years or sooner in high-energy-cost regions.
Are there rebates, tax credits, or certifications available for installing an energy-efficient metal roof?
Yes. Many cool metal roof products qualify for federal tax credits when ENERGY STAR® or IRS Section 25C requirements are met (check current legislation for exact incentives). Some states and local utilities offer additional rebates based on solar reflectance, emittance, or compliance with programs like Title 24 (California) and LEED. To maximize incentives, choose panels with documented CRRC ratings, ENERGY STAR® listings, and, if applicable, high recycled content or Environmental Product Declarations (EPDs). Always verify eligibility and submit required paperwork before or shortly after installation.
