Vegetative roofs, also known as green roofs, are layers of vegetation planted on rooftops. They help improve air quality, reduce urban heat, and manage stormwater by absorbing rainwater. These roofs can support various plants, including grasses, herbs, and small shrubs, depending on the climate and building structure. In addition to environmental benefits, vegetative roofs can enhance building insulation, leading to energy savings. They also provide habitats for wildlife and can improve the aesthetic appeal of urban areas. Many cities encourage the use of green roofs as part of sustainable development initiatives.
