I might suggest that (A) A good Aquaponics setup is in a greenhouse of some sort,....
But if there is a slop to your roof...
Maybe I'm misunderstanding something here but.. 1/4 inch for the roots seems pretty shallow...
I'd lay money that the shallower the beds the more tweaking...
Obviously weight can soon become an issue if using gravel in roof growbeds...
As far as rock is concerned...
Maybe consider this:
If you can seriously consider putting Aquaponics on the roof, then you can put them anywhere the sun will shine sufficiently. Think: What can you do or put on the roof that is better there than anywhere else?
A roof potentially has a lot of surface area, and a lot of exposure to sunlight, and is higher than the ground. I would think the best things you can do with a roof would be solar panels and solar water heating, etc. but that is obvious. A roof can make a great deck.
I've always liked the idea of an observation deck, enclosed with large panes of glass, like using sliding glass door panes, so that I could watch lightning storms with a great view while staying dry and comfy, or for watching meteor showers or the northern lights.

There will be a rooftop deck, and I intend for it to be surrounded by a vegetable garden.
I don't post my plans with a view to being talked out of them. Instead, I seek constructive ideas on how it can be done better. The rooftop aquaponics thing is a done deal for me. It's how I plan to construct at least one roof. I won't start off with a 10,000 ft.² roof and I won't invest my life savings into it. But I do intend to build a roof in this manner. That's a given for me, when I have a good idea I carry it through to some sort of conclusion.
