Study Shows Metal Roofing Can Save You Up To 40% on Energy Costs Annually

When it comes to roofing, homeowners and businesses alike are constantly searching for options that offer durability, energy efficiency, and long-term cost savings. Recent studies conducted at Oak Ridge National Laboratory (ORNL) have confirmed what we at True Metal Supply have known all along—metal roofing is an energy-efficient powerhouse.


Metal Roofing vs. Traditional Shingles: What the Data Says

The research compared various metal roofing configurations against traditional asphalt shingles in a controlled environment. The results? All metal roofs outperformed asphalt shingles in both summer and winter conditions, significantly reducing energy consumption.

Here’s a breakdown of the key findings:

  • Summer Performance:

    • Metal roofs with above-sheathing ventilation (ASV) reduced peak heat gain by up to 90% compared to asphalt shingles.

    • Attic temperatures under metal roofs were 9.9°F lower than those under asphalt shingles.

    • The heat transfer into living spaces was 50% to 80% lower, meaning less demand on air conditioning systems.

  • Winter Performance:

    • Metal roofs retained heat better than asphalt shingles, keeping attic temperatures up to 6.1°F warmer at night.

    • Homes with metal roofs lost 30% to 40% less heat compared to asphalt-roofed homes.

    • This translates into lower heating costs and a more comfortable indoor environment.


What Makes Metal Roofing So Efficient?

The study examined different combinations of insulation, reflective surfaces, and Phase Change Materials (PCM), which help regulate temperatures. The most effective setups included:

✅ Above-Sheathing Ventilation (ASV) – Creates an air gap that reduces heat buildup.

✅ Reflective Coatings – Deflects sunlight, reducing roof temperatures.

✅ Insulation Layers – Reduces heat transfer to and from the attic.

✅ PCM Technology – Helps absorb excess heat during the day and release it at night, stabilizing indoor temperatures.


At True Metal Supply, we offer high-quality metal roofing with these energy-efficient features, ensuring our customers enjoy year-round comfort and savings.


Why Switch to Metal Roofing?

  1. Lower Energy Bills – Reduced heat gain means lower cooling costs in summer and better heat retention in winter.

  2. Increased Comfort – Less temperature fluctuation inside the home.

  3. Sustainability – Metal roofs last 50+ years and are often made from recycled materials.

  4. Weather Resistance – Designed to withstand extreme temperatures, wind, and moisture.
