Solar and Photovoltaics

ERA supports product-neutral, science-based evaluation of roofing systems to ensure roof assemblies and rooftop energy systems perform reliably over the long term.

This page serves as a starting point for ERA’s solar-related content focused on EPDM roofing systems. As rooftop solar and photovoltaic systems become more common, the roof is increasingly viewed as a platform for energy generation rather than a long-term building component.

Using a roof to support energy generation introduces planning considerations that extend beyond the solar system itself. Roof system performance, durability, and service life become central to long-term success. When solar systems are expected to remain in place for multiple decades, the roof beneath them must be capable of performing for an equivalent period without requiring premature replacement.

EPDM has a long track record as a durable, flexible, and long-lasting roofing membrane. Its expected service life and system performance characteristics align well with the planning horizons associated with solar installations. For this reason, EPDM is often considered a practical foundation for solar-ready roof assemblies where long-term performance, risk management, and lifecycle planning are priorities.

ERA’s solar-ready roofing resources explore these considerations in greater depth, including education, research, and applied perspectives related to EPDM roof systems and rooftop solar integration.
