The Washington DC Metropolitan Region saw the installation of 2,164,926 square feet of green roofs in 2013. Washington has adopted public policies and programs that support green roof investment, including rebates of $7-$15 per square foot per green roof installed and credits that reduce stormwater fees. Public investment in green roofs yields multiple public cost saving benefits.
Green Roofs for Healthy Cities (GRHC) mission is to develop the green roof and wall industry across North America. Visit their website for more information about the 2013 Annual Green Roof Industry Survey.
