The Team
Joy Schmidt
Joy is the president of Xero Flor. While working for Xero Flor at the German headquarters, Joy oversaw many international projects and was instrumental in realizing the largest green roof in the world – a 10.4-acre extensive green roof on Ford Motor Company’s Rouge Assembly Plant in Dearborn, Michigan in 2002.
Under Joy’s leadership, Xero Flor Canada has successfully installed a great number of green roofs in varied climate zones, in five provinces across Canada. Joy is active in the green roof industry as she frequently volunteers to make presentations to organizations to provide education and promote public awareness of green roofs. She was involved in green roof workshops at the City of Toronto in 2005- 2006, which eventually led to the City of Toronto’s green roof incentive pilot program.
