Building code trends signal major shifts for the roofing industry

Staying informed on code trends is a strategic advantage that enables industry professionals to deliver safer, more resilient and higher-performing buildings.

Building codes continue to evolve as the construction industry responds to changing environmental demands, resiliency expectations and energy performance goals. During the February 2026 Single Ply Roofing Industry (SPRI) meeting, code consultant Amanda Hickman of The Hickman Group outlined key building code trends expected to influence how buildings are designed, reroofed and maintained in the years ahead. The trends align with SPRI’s ongoing work to guide building code development through research on roofing system installation and performance. 

SPRI has long positioned itself as a technical authority for the commercial roofing sector and actively monitors legislative and regulatory issues while intervening in code and testing matters that impact the industry. 

One of the most significant developments highlighted in the presentation is the evolving code development landscape itself. A formal SPRI Code Development presentation tracks emerging requirements and cost considerations tied to future code changes. 

Resiliency continues to gain momentum across codes as communities seek stronger protection against severe weather events. At the same time, tighter building envelope requirements such as air leakage control and mitigation of thermal bridging are becoming more prominent as regulators push for improved energy efficiency. 

The growing integration of renewables is also shaping code discussions. Roofing assemblies increasingly must accommodate photovoltaics and electrification while maintaining structural and weather performance. Energy codes already establish minimum insulation requirements for new and reroofing projects, reinforcing the roof’s critical role in overall building performance and energy reduction. 

Existing buildings are another major focus. Because roofing insulation significantly affects building performance, reroofing projects often present opportunities for energy upgrades that can reduce greenhouse gas emissions and long-term operating costs. Decarbonization and embodied energy considerations are also emerging alongside these efficiency goals, signaling a broader shift toward lifecycle evaluation of building materials. As performance-based pathways and energy credits become more stringent, high-performing roof systems will be increasingly valuable to building owners seeking compliance. 

Design innovation is also influencing the direction of codes. Occupiable roofs, solar rooftops and stormwater-focused blue roofs are gaining traction as cities look to maximize space and improve infrastructure resiliency. Meanwhile, tornado provisions and other wind-related requirements reflect a growing emphasis on structural durability. 

Complicating the landscape is the rise in state-level code variations, making it critical for contractors, consultants and manufacturers to stay current on regional adoption patterns. A state code adoption report referenced in the presentation is expected to provide additional clarity for the industry. 

With roofing assemblies playing a direct role in safety, sustainability and energy performance, staying informed on code trends is no longer optional. It is a strategic advantage that enables industry professionals to deliver safer, more resilient and higher-performing buildings while preparing for the next generation of regulatory change.
