extensive green roofs

Extensive green roofs are lightweight, low-maintenance rooftop gardens designed primarily for ecological benefits rather than human use. They consist of shallow soil layers that support hardy plants like sedums, which require minimal water and care. These roofs help reduce heat, improve air quality, and manage rainwater, minimizing runoff and urban flooding. They also provide habitats for wildlife and enhance the aesthetic appeal of buildings. Extensive green roofs are typically used on commercial and residential structures where adding significant weight is a concern.
