Urban rooftops are the flat or sloped surfaces of buildings in cities, often overlooked spaces that can serve various purposes. They can be used for gardens, recreational areas, or even solar energy installations. These rooftops help to reduce heat in urban environments and can improve air quality. Many cities are now promoting the use of green roofs to enhance biodiversity and provide habitats for wildlife. Rooftop gardens can also contribute to food production, allowing residents to grow their own fruits and vegetables. Overall, urban rooftops play a vital role in sustainable city living.
