Although regulations governing volatile organic compounds (VOCs)
are not new to the commercial roofing industry, the most recent
changes affecting single-ply roofing adhesives, sealants and
primers are a source of concern for many industry professionals.
The regulations set maximum allowable VOC content, extend beyond
simple odor control and focus on the environmental impact of these
chemicals.
Complicating matters is the fact that the new rules are being
enacted at the state—and sometimes local—level. It
often is difficult to determine the VOC contents of many commonly
used roofing products because jurisdictions determine whether a
solvent is considered a VOC.
Typically, regulations limiting VOC content of adhesives and
sealants apply to people who use, sell or manufacture such
products. As a result, many roofing contractors are faced with
regulations that may adversely affect product availability,
application methods, productivity and, ultimately, installation
costs.
