Technical Bulletin #104: Roof Color and Reflectivity

EPDM roofing delivers proven, science-based performance that goes beyond the outdated “black vs. white roof” debate. As modern building codes require significantly higher insulation levels, research consistently shows that insulation, not surface reflectivity, is the primary driver of energy efficiency in many U.S. climates, particularly ASHRAE Climate Zones 4–8. Multiple recent studies, including work by Harvard and ICF, find no consistent link between highly reflective white roof mandates and urban heat island reduction, while highlighting potential downsides such as increased heating demand, moisture risks, and unintended climate impacts. EPDM has a long track record of stable performance in real-world conditions where durability, insulation, and lifecycle outcomes matter most.

With an average service life of approximately 38 years, EPDM roofing systems significantly outperform many highly reflective membranes, reducing replacement frequency, embodied carbon, and total cost of ownership. EPDM offers exceptional durability, ease of repair, and compatibility with solar installations and vegetative roofs, making it a reliable foundation for long-term sustainability strategies. For building owners seeking a low-risk, resilient roofing solution backed by current research, EPDM provides consistent energy performance, avoids hidden moisture concerns, and supports long-term asset planning across a wide range of climates.
