A green roof is a form of vegetative roof which involves the growing of green plants on a roof. The design plan for a green roof focuses on creating an environment that supports plant growth while ensuring the structural integrity of the building and the sustainability of the roof system. This typically includes considerations for soil depth, water management, plant selection, and structural support. The design may also take into account the aesthetic appeal and functional benefits of the green roof, such as improved energy efficiency and stormwater management.
