Design of soil cover on the garage rooftop

Quick answer：

The design of soil cover on a garage rooftop involves creating a green roof system that can support vegetation. This typically includes a layer of insulation, a drainage layer, a root barrier, a filter fabric, growing medium, and finally the plants themselves. The design must consider factors such as soil depth, water management, and structural integrity to ensure the safety and longevity of the garage and the green roof system.
