Landfills every year, according to the Environmental Protection Agency. The money spent on installing a metal roof can be recovered from the savings in monthly cooling and heating costs thanks to the reflective properties of this type of roof.
Metal roofs reflect solar radiant heat rather than absorb it, which year-round, but especially during long summer days, can reduce cooling costs by up to 25 percent, according to Metal Roofing Alliance.
