The benefits of green roofs on the management of stormwater runoff and reduction of the urban heat-island effect can be maximized by using a variety of plants, according to some studies. Sedum alone can limit the capacity of green roofs because it absorbs heat, said Scott MacIvor, a Ph.D. student in biology at York University in Toronto. Roofs also benefit from hosting fungi communities, which can aid plant growth, according to a study by Krista McGuire, an assistant professor of biological sciences at Barnard College in New York.
