For certifying colors, how would coaters certify colors that they make themselves (match colors)? Would this be possible or would there be “roof colors” set?
This question is best answered by the individual paint manufacturer. There is a complicated dynamic at play. The paint manufacturer may opt for a standard range of reflective paints, or may offer custom colors. Pricing may vary. The number of colors in the reflective range may influence the coaters’ pricing, at least to some extent. The roofing fabricator may choose to offer a limited line of EnergyStar compliant (or otherwise reflective) products in order to maximize production efficiency, even if the paint or the coated stock is available in a wide range of colors. As for certification, it depends on the regulation. EnergyStar compliance, for example, is self-certified, and can be done by anyone with the right equipment (spectrophotometer or D&S instrument) and a spreadsheet. CRRC ratings must be certified by an accredited laboratory, in the case of standard colors, or by an accredited paint manufacturer, in the case of custom colors.
