Roofing Studies
Long before cool roofing became a buzzword to signify reflective roofing surfaces in the mid-1990s, the earliest reflective single-ply roofing systems, notably polyvinyl chloride (PVC), touted energy efficiency as part of their sales pitch. By the late 1990s, cool roofing was the hottest trend in commercial roofing, and white, thermoplastic single-plies began a sustained run as the fastest-growing category of commercial roofing systems.
The popularity of cool roofing systems over the last ten years stems from the enormous energy savings they are providing to building owners nationwide. Demand is also fueled by utility company rebates in every part of the country, as well as federal, state and local legislation and incentives designed for both energy efficiency and broader environmental purposes.
The Cool Roof Rating Council (CRRC) is a non-profit association that implements and promotes fair, accurate performance ratings for solar reflectance and emittance from roof surfaces. CRRC’s Product Rating Program enables roofing manufacturers to label various roof surface products with radiative property values rated under strict guidelines. All tests for measuring cool roof properties are performed by accredited, independent laboratories following established ASTM International protocols. Performance data for products from numerous manufacturers can be found on their web site, www.coolroofs.com.
