Cool Roof

A cool roof has the ability to deter the sun’s heat and radiation from being transferred into your building, significantly reducing your cooling load and saving you money on energy bills.

Heat

In the Summer...

A cool roof reduces the heat transferred into a building by reflecting the sun’s rays (solar reflectance), and by re-emitting the absorbed heat back into the atmosphere (thermal emittance). Such properties allow a cool roof to remain 70-100°F cooler than the standard surface, translating into a decreased need for air conditioning and increased energy savings.

Winter

In the Winter...

The sun is less intense, there are fewer hours of daylight and roofs are often covered with snow; all contributing factors that make a roof a negligible source for heat gain. As a result, the heating penalty often associated with cool roofs in the winter is insignificant and heavily outweighed by the savings achieved during the cooling season.

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 with the installation a cool roof.
  • 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”- the increase in ambient air temperature due to dark roofs and other non-reflective surfaces that absorb and trap solar radiation/heat. Relieving such an effect leads to a diminished need for A/C, consequently reducing smog formation & CO2 emissions.
  • Green Building LEED® Certification - LEED® certification is 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, which aims to reduce the heat island effect and its impact on microclimates and habitats.
