Too often, when homeowners are selecting a roof, they neglect to consider the color. The color of metal buildings can have serious impacts on the roof’s energy efficiency. Temperatures of the top floor of a building can swing by anywhere from 20 to 40 degrees simply based on the color of the roof. This can drive up energy consumption by 20 percent, leading to greater utility bills. Therefore, it is critical for every homeowner to know how the color of a metal roof can impact energy consumption.
