A roof garden, also known as a green roof, is simply a garden placed on the roof a building. It helps the ecosystem and the environment by providing ecosystem services (i.e. improve storm water management, mitigate urban heat-island effects, provide wildlife habitat, and improve air quality) in an urban environment. Roof gardens can serve multiple purposes. For instance, they can be a place where you go to relax and enjoy the landscape architecture provided by your roof garden or even be a place to grow food and farm. Roof gardens are attracting more interest and have even been developed on local government buildings in cities such as Chicago and Rochester, New York. Consider these benefits if you’re thinking of adding a garden to your roof.
