Check our latest roofing ratings for detailed results for 16 different lines of asphalt roofing shingles.

Sri roof rating.

Berridge s kynar 500 hylar 5000. Asphalt roofing shingles with higher sri ratings are cooler in the sunshine. We ve all been hearing more and more about cool roofing and rightly so this is a technology that according to the cool roof rating council can reduce utility costs by 7 15 as well as help reduce air temperatures in densely populated areas. Cool metal roof colors are optimal for reducing energy consumption particularly where cooling loads dominate.

The higher the sri the cooler the roof will be. The cool roof rating council is an excellent resource to finding out sri solar reflectance and thermal emittance values. The cool roof rating council was created in 1998 to develop accurate and credible methods for evaluating and labeling the solar reflectance and thermal emittance radiative properties of roofing products and to disseminate the information to all interested parties. They are an independent organization that evaluates reflectivity capabilities of roofing products initially and 3 years after installation.

Berridge metal roofing is cool and sustainable the high reflectivity emissivity and solar reflectance index sri of berridge metal roofing helps mitigate the heat island effect. Solar reflectivity 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. The cool roof rating council accepts test reports from approved testing laboratories and then compiles the information in an easily accessed database.

Most manufacturers still report separate emissivity and reflectivity data in their literature but the cool roof rating council an organization that verifies and labels cool roofing products has begun using the measure while retaining reflectivity and emissivity measurements. The cool roof rating council is a not for profit organization that validates the reflective and emissive properties of cool roof products. These shingles must have an initial solar reflectance of at least 0 25 and a three. For information on roofing materials and installation see our roofing buying guide.

Higher sri ratings for shingles mean greater reduction in cooling load on a home. Cool roof rating council crrc has created a rating system for measuring and reporting the solar reflectance and thermal emittance of roofing products. Solar reflectivity r solar reflectance index sri by color. Cool roofing products are classified in many cases by their solar reflectance index sri.

Cool roof rating council. Asphalt shingle products with an energy star rating do not utilize the sri compliance path.
