Cool Metal Roofing - Energy Savings
Thousands of homeowners are turning to cool metal roofing as an innovative way to enhance the value and beauty of their homes. Your home is probably your biggest investment so improving and maintaining it should be a top priority.
Many roofing options, though, only restore the value that was lost from having an aged roof on the home. They do little or nothing to provide lasting additional value. The benefits of metal roofing, though, provide increased value that stays with your home instead of diminishing over time. Chief among those benefits is energy efficiency.
A Classic Metal Roof reduces home energy costs in several ways.
Save On Your Energy Bills
Our Kynar 500® and Hylar 5000® coatings incorporate our advanced hI-R Heat Barrier technology to create a roof that keeps your home naturally cooler thanks to special reflective pigments. The complex chemical structure of these pigments reflects the infrared portion of the sun’s rays that is most responsible for heat gain. A hI-R Classic roof leaves the attic space and the entire home much cooler in the summer. Proud owners of Classic roofs report saving up to 20% or more on their energy costs.
The formed thickness of your Classic roof provides further energy efficiency. The integral “dead” airspace between the aluminum and your roof deck acts as a thermal break, stopping heat transfer by conduction. This behaves much like the airspace between the plates of glass in a thermal pane window.
The ability of a low weight Classic aluminum roof to be installed over your old shingles is also beneficial. In addition to saving your money and avoiding landfill disposal, your old roof provides thermal mass – additional insulation to help keep summertime heat outside of your attic.
A six month energy study from an Indiana Homeowner...
Here is a six month study of the energy savings of a cool metal roof as presented by a homeowner from a moderate climate in Indiana after his new energy-efficient 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.
Average temperature was the same in 2010 and 2011. Energy use was 328 kw less in 2011 for a savings to the homeowner of $47.00
Average temperature was 1 degree cooler in 2011 than 2010. Energy use was 404 kw less in 2011 for a savings to the homeowner of $58.00
Average temperature was 1 degree cooler in 2011 than 2010. Energy use was 305 kw less in 2011 for a savings to the homeowner of $44.00
Average temperature was 2 degrees cooler in 2011 than 2010. Energy use was 356 kw less in 2011 for a savings to the homeowner of $51.00
Average temperature was 3 degrees cooler in 2011 than 2010. Energy use was 642 kw less in 2011 for a savings to the homeowner of $80.00
Average temperature was 2 degrees cooler in 2011 than 2010. Energy use was 363 kw less in 2011 for a savings to the homeowner of $52.00
Less energy use, lower electric bills
- The homeowner reported that his September and October electric bills were the lowest he has ever had in the home.
- During this six month period, the homeowner’s total energy savings was $332 and his energy consumption was over 28.5% less after the cool metal roof was installed.
- Part of this savings is due to slightly lower temperatures in 2011 but the homeowner also reported having more house guests in 2011 which would have increased his energy use.

Cool Roofing At Its Best
This blocking of both radiant and conductive heat provides the best possible recipe for a cool roof for your home. Studies have shown reduced attic temperatures of up to 34%. When your attic is kept cooler, your air conditioner runs less and you save money.
A Classic metal roof can also help you achieve good attic ventilation. Ventilation is a key to even greater energy efficiency and it also helps guards against winter ice damming in cold climates.Learn about Roofing Alternatives
