These things have caught the attention of some folks with outbuildings that are fairly flat. I was looking at the construction of a green roof several years ago on a chicken coop.
People with more building knowledge may want to correct me where I go wrong but here is a diagram of such a roof from an outfit in Australia:

The "waterproof membrane" is becoming familiar to all of us. The roofers put one on my deck roof several years ago. I guess, they can come in pre-cut sizes and seamlessly fit small structures. These membranes take the place of some of the composite roofing that is often put up on flat roofs.
The "Flo-Cell" is a product I didn't know about. As best as I can tell, it isn't uncommon. This is something that is used on the exterior of a basement wall. It allows the movement of water. How about that? You really don't want your green roof soggy . . . and heavy.
This sort of shows that the roof is concrete but I don't know how likely that is. This may be totally off-base but I have heard that green roofs may not be any heavier than those asphalt/gravel roofs on so many large buildings. The advantages of having a green roof, besides a roof-top garden, is the insulation it provides against cold and heat.
