What roofing type is characterized by high solar reflectivity and comes in white?

The roofing type characterized by high solar reflectivity and typically comes in white is Polyvinyl Chloride (PVC) roofing. This material is well-known in the roofing industry for its energy-efficient properties, particularly the ability to reflect sunlight and reduce heat absorption. The white coloration enhances this reflectivity, making it a popular choice for commercial and industrial buildings as it helps to keep temperatures down, which can lead to lower energy costs for cooling.

In contrast, other roofing materials mentioned do not possess the same level of solar reflectivity. Tar and gravel roofing, while durable, primarily has a darker color that absorbs more heat. EPDM roofing, which is made of a synthetic rubber, is generally black and also absorbs heat rather than reflecting it. Asphalt shingles, commonly used in residential roofing, are available in various colors, but they generally do not exhibit the high solar reflectivity associated with white roofing materials.

Thus, PVC roofing stands out for its reflective qualities and is specifically designed to enhance energy efficiency through its white surface, making it the correct choice for the question.
