The Next Step in Solar Reflectance Testing for Roofing Products

When it comes to roofing, after the expected service life of individual products, the most common attribute that is used to describe the performance is often the solar reflectivity. Solar reflectivity is the percentage of solar energy that is reflected from the roof surface instead of being absorbed into the roof and building as a whole.

When it comes to roofing, after the expected service life of individual products, the most common attribute that is used to describe the performance is often the solar reflectivity. Solar reflectivity is the percentage of solar energy that is reflected from the roof surface instead of being absorbed into the roof and building as a whole. With the ever-increasing cost of energy, there has been a focus on solar reflectivity over the last two decades as a way to determine the energy efficiency of roofing materials and their impact on urban heat islands. Even though the debate continues about whether to use highly reflective roofing products in some climates or all of them, another more basic issue continues to face the industry.
