Trends and Considerations for Design of Sustainable Roofing Systems

Current trends applied to sustainable design and construction of roofing systems emphasize widespread practices that cover the design and construction process of sustainable building in general. These principles, such as those contained in the Green Building Council’s LEED rating system, emphasize factors such as improving thermal performance through enhanced insulation and roof surface reflectivity, increased recycled material content, and use of rapidly renewable resources. These features are important to sustainability but do not fully recognize or emphasize some important aspects of roofing system performance that differentiate roofing from other building systems.
