Cool Roof Energy Highlights


  • Comfort - Improved comfort due to lower internal temperatures, especially on the higher levels of multi-story buildings.

  • Cost Savings - Reduce energy costs, as well as the maintenance costs of your roof and HVAC equipment.

  • Prolonged Life Cycle - As a result of a reduced cooling load, the life and effectiveness of your air conditioning system can be prolonged.

  • Roof Maintenance - The greatest cause of roof deterioration is heat fluctuation resulting from the sun's daily cycle. Therefore, a highly reflective [cool] roof lasts longer and requires lower maintenance due to reduced thermal flux.

  • Environmental Benefit - Cool roofs can dramatically aid in relieving the urban heat island effect, which diminishes the need for A/C and consequently reduces smog formation and CO2 emissions.

  • Green Building LEED Certification - A nationally recognized standard for measuring building sustainability, and can be achieved by obtaining a variety approved credit points accepted by the USGBC LEED commission. Eligible cool roofs can qualify for SS Credit 7.2.
