obviously something's there or you would fall in

Lwiddis, when you drill into any surface you can feel the screw biting into it or not. My screws should be biting into the plywood. There has to be something under the thin rubber roofing. Even if the plywood was damaged and a screw stripped, it still wouldn't just pull right out. Installing the panels should have been one of the easiest parts of the install.

Some have used VHB tape depending upon roof type.

Rubber epdm with 3/8" plywood

I have very limited space to fit the panels. I don't think I would be able to fit both sides of my panels right on the studs, but that is a good idea running long pieces aluminum into the beams. I still don't understand why I am not feeling any plywood under the rubber when I screw. It should be 3/8". I can see partially the plywood and rubber roofing material in the vent whole.

What material is the roof made from?

This sort of technology may work:

Try a stud finder. Can you access the roof from inside like a light or speaker hole? If so you will have a better idea of roof construction. You can also run long pieces of aluminum angle that is screwed into beams, etc. Well nuts might also be a good choice for you.
