A properly designed and installed extensive green-roof system can cost $108–$248/m 2 ($10–$23/sq ft) while an intensive green roof costs $355–$2,368/m 2 ($33–$220/sq ft) However, since most of the materials used to build the green roof can be salvaged, it is estimated that the cost of replacing a green roof is generally one third of the ...

Green roofs, blue roofs and green walls (as part of green infrastructure) are also nature-based solutions that can be implemented in urban areas. They can reduce the effects of urban heat islands, capture stormwater, abate pollution, and act as carbon sinks. At the same time, they can enhance local biodiversity.
Green and blue roofs also help reducing city runoff by retaining rainfall providing a potential solution for the stormwater management in highly concentrated urban areas. [64] The social benefit of green roofs is the rooftop agriculture for the residents. [42] Green roofs also sequester rain and carbon pollution.
