It also takes a toll on the sunlight below.

I still somewhat like the idea, but maybe it should be some carcasses above the actual roofs, so that roof maintenance would be easier (maintenance of these gardens as well, I think).

And no trees, just grass, moss, plants like wild grapes.

In that case maybe it won't have to be flat roofing.
