Matterhorn Metal Roofing Cool Savings Estimator Disclaimer
Calculations made using Department of Energy's Steep Slope Calculator produced by
Oak Ridge National Laboratory (1).
Household savings calculations made assuming
a 2400 sq. ft. roofing area, insulation R-value of 10.00, and state energy price from
July 2014 (2).
Savings estimates based on comparison to home with black asphalt
roof. Cumulative savings projections made using estimated price of electricity from
the Energy Information Administration's 2015 Annual Energy Outlook (3).
savings estimations may or may not reflect actual savings experienced by
homeowners due to numerous savings variables related to home specifications and
location including, but not limited to, efficiency of electronic devices, temporary increase in electricity usage (i.e. a friend visited and plugged in all their electronic devices for a month), fluctuations in temperature, etc.
