The Energy Efficiency of Metal Roofing
The Energy Efficiency of Metal Roofing:
Did you know a metal roof can easily help you save as much as 25% off of your annual home energy bill, and help reduce your overall energy waste. According to a US independent report by the Oak Ridge National Laboratory “2008 ACEEE Summer Study on Energy Efficiency in Buildings“, homeowners can save up to 40% in home cooling costs in the summer, and 10-15% in home winter heating costs, based on a strapping system of 4 inches between the plywood and the metal on top.
Metal roofing has a cool reflective surface, which reflects solar radiation in the form of heat back into the atmosphere, rather than absorbing it inside your home or building.
While copper and zinc are the least energy efficient types of metal roofing, due to the darker colors and thicker gauge of metal, they absorb and store more heat compared to aluminum and steel. That being said, they are still much “cooler” and green than asphalt shingles.

[…] Traditional asphalt shingle roofs, your home’s first line of protection against weather and temperature protection is inadequate. Even in the type of winters and summers we get in the north east, asphalt shingle roofs average only 12 to 17 years of service life. With a modern metal roof you can have a system that can easily last two to three times longer, while also providing superior energy efficiency, durability, reliability, and often a significant energy savings.
