A cool roof is designed to reflect more sunlight than a conventional roof, absorbing less solar energy. This lowers the temperature of the building just as wearing light-colored clothing keeps you cool on a sunny day.

A cool roof is one that strongly reflects sunlight (solar energy) and also cools itself by efficiently emitting any heat that was absorbed. The roof literally stays cooler and reduces the amount of heat conducted into the building below.

A cool roof is made of a material or has a coating that can lower the roof surface temperature, decreasing the amount of heat transferred into a residential or commercial building. In general, traditional roofs absorb sunlight during the day, heating the building and the surrounding air.

Learn basic info about cool roofs and walls or search for codes, standards, incentives, and programs that require or promote the use of highly reflective building products

Feb 27, 2025 · Reduced energy use: A cool roof lowers the amount of heat transferred to the building, which allows it to stay cooler and use less energy for air conditioning. In air-conditioned residential buildings, solar reflectance from a cool roof …

Cool roofs can save energy as well as beautify your home. The immediate and long-term benefits of roofs that stay cool in the sun have made cool roofing the fastest growing sector of the building industry.

Cool roofs are designed to lower the temperature of your home in summer months, making you more comfortable and potentially reducing your energy bill. Cool roofs achieve this by reflecting some of the infrared (IR) light from the sun.

Cool roofs can help many building owners save money while protecting the environment. This guidebook has been created to help you understand how cool roofs work, what kinds of cool roof options are available, and how to determine if cool roofing is appropriate for your building.

A cool roof is a roofing system that delivers higher solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the building) and higher thermal emittance (the ability to radiate absorbed, or non-reflected solar energy) than standard designed roofing products.

Mar 3, 2025 · Cool roofs—also called highly reflective roofs—are light-colored or white roofs that bounce the sun’s heat back to the sky rather than transferring it to your home’s interior, making them more energy-efficient.
