Evaluating the Feasibility of Implementing a Green Roof Retrofit on Pitched Residential Roofs

Green roofs are one solution to stormwater runoff which is a major environmental problem. However, the majority of green roofs are primarily implemented on flat roofed commercial buildings and not residential homes with sloped roofs. Team SO GREEN designed a light-weight green roof system retrofit for residential homes. Between June and November 2014, green roof performance data was collected and compared between the designed sloped roofs and a non-sloped control. The sloped design performed well and one test slope was improved with a recirculating irrigation system. An economic analysis was made and a focus group determined preliminary consumer interest, aesthetic preferences, and barriers. This study enriches the body of knowledge regarding bringing green roof systems to the residential home market.
