A multi-faceted field research program regarding seven atactic polypropylene (APP) modified bitumen membrane roof systems and four reflective coatings began in 1991. This long-term project is evaluating the performance of various APP modified bitumen membranes (both coated and uncoated), the comparative performance of coating application soon after membrane installation versus preweathering, coating performance, and aspects of recoating. This paper is a progress report on the in situ thermal performance of the various types of coatings compared to the thermal performance of the exposed membrane. The thermal performance of an adjacent ballasted ethylene propylene diene terpolymer (EPDM) roofing system is also described.
