Tennessee legislature amends roofing standards to exempt solar reflectance rules

On April 8, 2025, the Tennessee State Legislature introduced Senate Bill 1194, which aims to amend existing regulations regarding roofing standards in the state. The bill, now known as Public Chapter No. 149 after being substituted by House Bill No. 801, specifically addresses the solar reflectance and thermal emittance requirements for low-sloped roofs as outlined in the International Energy Conservation Code.

The primary provision of the bill exempts Tennessee from adhering to the 2021 International Code Council's standards for these roofing requirements. This change is significant as it allows for greater flexibility in roofing materials and designs, potentially impacting construction practices across the state. The bill also empowers the state fire marshal to establish rules to implement these changes, ensuring compliance with the Uniform Administrative Procedures Act.

Debate surrounding the bill has centered on its implications for energy efficiency and environmental standards. Proponents argue that the exemption could reduce costs for builders and homeowners, while opponents express concerns about the potential negative impact on energy conservation efforts in Tennessee. The discussions reflect a broader tension between economic considerations and environmental sustainability.

The bill is set to take effect upon becoming law for the purpose of rule promulgation, with full implementation scheduled for July 1, 2025. As the state moves forward, the implications of this legislation could influence both the construction industry and energy policy in Tennessee, making it a noteworthy development in the ongoing conversation about building standards and environmental responsibility.
