Cool Roof Rating Council

The Cool Roof Rating Council (CRRC) was created in 1998 to develop accurate and credible methods for evaluating and labeling the solar reflectance of roofing products. Many of the products that have a CRRC certification are also certified by Energy Star rating as well, due to the proven energy savings that are accompanied by having a reflective roof covering on a building. At Columbia Roofing and Sheet Metal, about 90% of all commercial roofing products that we use carry both the Cool Roof Rating Council and the Energy Star ratings.

Heat Island Effect

Here in the Pacific Northwest, we are in a region that has more heating days verses cooling days. This might make it seem like a “Cool Roof” would be unnecessary, there are, however, many benefits of a cool roof that make them perfect choices for the Northwest.  One of the main benefits of a cool roof is mitigating the heat island effect. According to most authorities, the temperatures within the downtown areas of urban areas can be anywhere between 2? to 8?F warmer than the ambient temperature in the surrounding areas. All of the white membrane roofs that we install have been certified from the Cool Roof Rating Council (CRRC) as “Cool Roofs” and many of them have an Energy Star Rating. These roof surfaces have been proven to reduce the heat island effect and cool the actual temperature of the immediate surrounding area.
