Since 2004, Green Roofs for Healthy Cities has conducted an annual survey of its corporate members in order to collect data on the growth and composition of the green roof industry across North America. This resource allows GRHC to speak confidently about the shape and state of the North American green roof market, and provide support for policy outreach efforts in municipalities across the United States and Canada. The survey report also provides valuable market intelligence on green roof installation hot-spots, and tracks the size, source, and variety of green roofs that have been installed.


The 2018 Green Roof Industry Report Executive Summary is now available.

Full report available this winter for GRHC Members.
