| As reported by the Cool
Metal Roofing Coalition and the Oak Ridge National Laboratory, installation
of reflective metal roofing can save your home up to 40% in summer
cooling energy costs while highly emissive metal roofs can reduce
urban air temperatures by as much as 12 ° F.
Combined, these benefits mean
less money out of your wallet, less dependence on energy resources and less
general air pollution in your neighborhood and across the nation.Americans spend about
$40 billion annually to air condition buildings — one-sixth of all
electricity generated in this country.

Why choose a Metal Roof
- ENERGY STAR qualified roof products reflect more of the sun's rays. This
can lower roof surface temperature by up to 100F, decreasing the amount
of heat transferred into a building
- ENERGY STAR qualified roof products can help reduce the amount of air
conditioning needed in buildings, and can reduce peak cooling demand by
10–15 percent
During building design
and when your existing roof needs replacement are both excellent times to
consider reflective roofing. The ENERGY STAR energy-efficiency criteria do
not include a specification for roof insulation. However, in addition to
reflectivity, roof insulation (measured by the R-value) plays an important
role in building energy consumption for heating and cooling. The colder the
climate, the greater the need for a higher R-value to ensure that less heat
is lost from the building envelope. To determine the minimum R-value for a
given location, refer to the International Energy Conservation Code. |
