Survey: Vegetated roof industry is blooming

May 01, 2008 |

The installation of vegetated roofs in North America increased by 30% between 2006 and '07, according to the third annual Green Roof Market Industry Survey. The Green Roofs for Healthy Cities nonprofit organization (www.greenroofs.org), which sponsors the yearly survey, reported that slightly more than 2.4 million sf of rooftop was planted during the past 12 months.

Once again the city of Chicago takes the top spot, having planted 517,633 sf of rooftop last year. The city has numerous policies and programs in support of green roofs, so vegetated roofs should continue to grow above the Windy City.

Coming in a distant second is Wilmington, Del., followed by Baltimore, Brooklyn, N.Y., and Virginia Beach, Va.
