Green Roof Installations

Green is still good. The latest government motivation is toward green roof installations.

Among the benefits of the Clean Energy Stimulus and Investment Assurance Act of 2009 (S.320) introduced by Sen. Maria E. Cantwell (D-Wash.) is to provide financial incentives for homeowners or commercial building owners which chose to install green roofs on their buildings.


A green (or sod) roof features of vegetation-usually drought-tolerant plants, or shrubs-that is planted in a growth medium. The roof generally involves a multilayer system of waterproof and root-repellent membranes, a drainage system, filter cloth, and lightweight soil.


Green roofs have been around for thousands of years. One of the first notable appearances of green roofs occurred in the Hanging Gardens of Babylon around 500 BC. The site is considered one of the Seven Wonders of the World.


The thrust of the Clean Energy Stimulus and Investment Assurance Act of 2009 is to create green-collar jobs and revitalize the economy through clean energy investments.

Section 506 of the bill, offers property owners a 30 percent tax credit for qualified green roof expenses. The tax credit applies to both new and retrofit projects, but it requires that at least 50 percent of the roof area be covered with vegetation.

“This is a watershed moment for the green roof industry,” observes Steven W. Peck, founder and president of Green Roofs for Healthy Cities, which worked with the American Society of Landscape Architects to help Sen. Cantwell’s office draft the section of the bill that is focused on the green roof incentive. “This bill will deliver an enormous number of green collar jobs, not just today, but also in five years from now, while also saving energy, improving stormwater management, cooling cities, cleansing the air, and

beautifying our rooftops.”


Builder magazine reports that, Green Roofs for Healthy Cities has launched a new, multi-disciplinary Green Roof Professional (GRP) program–much like U.S. Green Building Council’s LEED Professional Accreditation-and will administer the first exam at its annual conference this June in Atlanta. Under the program, an individual can become GRP-accredited to provide green roof design, products, and installation services to meet the new demands that potentially could be generated from this bill.


American landscape architects and a Canadian nonprofit green roof industry association says that the United States could see a surge in green roof installations if a provision in a recently introduced Senate stimulus bill becomes law.
