Stormwater management

Green roofs play a crucial role in managing stormwater runoff. They absorb rainwater and slow down the rate at which it enters the drainage system. This helps to reduce the strain on urban infrastructure, such as sewers, and prevents flooding. By reducing stormwater runoff, green roofs help to enhance the overall resilience of cities.

Air quality improvement

Green roofs help to improve air quality by absorbing carbon dioxide and other pollutants. The plants on the roof filter the air, reducing the presence of harmful substances and improving the overall air quality in the surrounding area. This has direct benefits for public health and contributes to a more sustainable urban environment.

Biodiversity conservation

Green roofs also provide valuable habitats for birds, insects, and other wildlife in urban areas. They create green spaces in the midst of concrete jungles, promoting biodiversity and supporting the local ecosystem. By providing nesting opportunities and food sources, green roofs contribute to the conservation of urban wildlife.
