  • Energy Star® Roof Products

    Energy Star is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices. Energy Star labeled roof products can save money and the environment by reducing energy use. They work by reflecting more of the sun's energy back into the atmosphere, keeping your building cooler and reducing your air conditioning bills. Because much of the United States' electricity is generated by burning fossil fuels creating air pollution, reducing the amount of energy needed to cool buildings helps to reduce the production of air pollutants. In addition, the air in urban areas can be 6-8°F hotter than surrounding rural areas. Scientists call these areas "urban heat islands." These heat islands can make the effects of local air pollution worse and can increase the cooling costs for buildings within the area affected by the heat island.

    What is a Cool Roof?

    A cool roof reflects and emits the sun's heat back to the sky instead of absorbing and conducting it to the building below.  "Coolness" is measured by two properties, solar reflectance and thermal emittance.  Both properties are measured from 0 to 1 and the higher the value, the "cooler" the roof.

    This green building material offers Solar Reflectivity ratings and Solar Reflectance Index numbers to show the ability of our paint coatings to reflect and emit the sun’s energy. Solar Reflectivity (SR) or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR value is a number from 0 to 1.0. A value of 0 indicates total absorbance and 1.0 indicates complete reflection. ENERGY STAR requires SR testing of both new and aged roof products. New products must have an SR value of 0.25 or higher for steep slope roofing (above 2:12) and an SR value of 0.65 or higher for low slope roofing (2:12 or less). Aged testing takes three years to complete, so not all products that meet the initial requirements are qualified.

    The Solar Reflectance Index (SRI) is used to determine compliance with LEED requirements and is calculated according to ASTM E 1980 using values for reflectance and emissivity. To meet LEED requirements, a roofing material must have an SRI of 29 or higher for steep slope roofing and a value of 78 or higher for low slope roofing when evaluated under medium wind conditions.

    Important Resources

    The Cool Roof Rating Council  (CRRC) is an independent and nonbiased organization that has established a rating system. The core of the CRRC is its Product Rating Program through which roofing product manufacturers can label their products with solar reflectance and thermal emittance values measured by CRRC Accredited Independent Testing Laboratories.  The CRRC does not set a minimum definition for "cool".  However, code bodies and programs can reference its rating system.  The CRRC simply lists the measured radiative property values in its Directory.  Any roofing product can be tested as long as it is in compliance with the CRRC Program Manual, CRRC-1.  A product's placement in the Directory does not mean that the product is "cool" as defined by any particular code body or program. For more information on the CRRC, visit their website at

    The mission of the Cool Metal Roofing Coalition is to educate architects, building owners, specifiers, code and standards officials and other interested parties on the sustainable, energy-related benefits of cool metal roofing. This website provides many articles and studies of buildings using Cool Metal Roofing.
