Expected effects from climate change are increased precipitation and rising temperatures. This in combination with urban densification where green areas are replaced by hard surfaces contributes to a higher risk of floods and heat islands, since green areas provide ecosystem services which disposes local stormwater and has a cooling effect. The aim of this study was to investigate how green roofs and its ecosystem services can contribute to more sustainable cities. This study was conducted by literature data combined with interviews. The result of this study showed that the most important function of green roofs is stormwater management. The space in cities is limited and many functions e.g., infrastructure and buildings should fit in limited surface. The lack of space is a problem to ensure that there are sufficient green spaces that provides ecosystem services. This problem could decrease by using the roofs to a greater extent to ensure ecosystem services in form of e.g., stormwater management. However, the municipalities’ room for maneuver to plan with green roofs showed to be limited by regulations. In conclusion, there is potential to build green roofs to a greater extent as they have many benefits that are useful in urban densification and to counteract negative effects of climate change, e.g., stormwater management and temperature control. The municipal actors would therefore need more room to maneuver to be able to implement green roofs in community planning to a greater extent.
