Abstract
This paper describes a study of the effect of weathering in California on the solar reflectance of white roof coatings. About 20 roofs that had been coated with one of three roof coatings were surveyed. Data on age, roof substrate and conditions, and solar reflectance were collected and analyzed. Some roofs were washed to determine whether a high solar reflectance could be restored.
