A Through Z of Associations: Part 6

This is the last in a series of posts discussing the various associations that benefit roofing manufacturers, contractors, and other industry professionals.


The Single Ply Roofing Industry (SPRI) is a recognized technical and statistical authority on single-plies, representing sheet membrane and related component suppliers in the commercial roofing industry. SPRI provides a forum that enables members to collectively focus their expertise and efforts on critical industry issues. By acting as a trade organization, the group can effectively improve product quality, installation techniques, workforce training, and other issues common to the industry.

Since 1981, SPRI has been a resource for building owners, architects, engineers, specifiers, contractors, and maintenance personnel, providing information about commercial roofing components and systems.


The U.S. Green Building Council (USGBC) is a nonprofit organization that certifies sustainable businesses, homes, hospitals, schools, and neighborhoods. USGBC is dedicated to expanding green building practices and education through its LEED® (Leadership in Energy and Environmental Design) Green Building Rating System™.

The LEED system is a voluntary, consensus-based national rating system for developing high-performance, sustainable buildings. LEED addresses all building types and emphasizes state-of-the-art strategies in five areas: sustainable site development, water savings, energy-efficiency, materials and resource selection, and indoor environmental quality.

LEED Accredited Professionals (LEED APs) have demonstrated an understanding of green building techniques, the LEED Green Building Rating System, and the certification process.


Founded in 1982, the Vinyl Institute (VI) is a U.S. trade association representing the leading manufacturers of vinyl, vinyl chloride monomer, vinyl additives and modifiers, and vinyl packaging materials.

VI advocates the responsible manufacture of vinyl resins; life-cycle management of vinyl products; and the promotion of the value of vinyl to society. The VI has produced a number of publications addressing the environmental aspects of vinyl products, including roofing systems.
