Residential Energy Savings from a Cool Metal Roof
As presented by a homeowner from a moderate climate in Indiana after his new energy-efficient cool metal roof was installed in early 2011. His roof qualified for the federal energy efficiency tax credit. While savings will always vary somewhat based upon the individual home and homeowner, potential savings can be expected to be even greater in warmer climates. Cool metal roofs work by reducing heat gain into the attic and home, reducing energy consumption through lowered air conditioning needs.
