Hello everyone,
We have had several contractors on site by now, but unfortunately, we have not yet found a satisfactory solution. Unfortunately, we only have a construction height of 15cm (6 inches) from the unfinished ceiling to the sliding patio door. Adding to the challenge, I use a wheelchair, so the transition from the sliding patio door to the terrace must be barrier-free. The garage beneath the terrace is unheated. We want to prevent any condensation from forming on the garage ceiling and ensure that the terrace is properly drained. For the flooring, we are considering terrace slabs with a thickness of 2cm (0.8 inches).
I have created the following sketch for this.
We would be very grateful for any ideas.

The roof will certainly have a slope to allow water to drain. Adjustable supports are placed and leveled on it, and decking boards or WPC are attached directly to the supports. If you’re unsure, have a professional handle it. If you use WPC, choose solid boards instead of hollow ones.
What kind of tradespeople did you have working on this? I mean, from which profession?
In my opinion, you need roofing specialists. The garage must be waterproofed according to flat roof regulations. The insulation is probably only used to create the slope—since the garage is unheated. I can’t say for sure if 15 cm (6 inches) is enough, but I would assume so. The choice of surface covering should essentially not matter as long as everything underneath is done correctly. For maintenance purposes, I would tend to recommend a surface with boards (regardless of the material), as they can be removed every 10 years or so to inspect the waterproofing and then reinstalled.

In our case, it was done by applying a white screed with a slope directly onto the structural ceiling. This served as both insulation and slope at the same time. On top of that came a so-called elephant membrane (I believe the material is called EPDM or something similar), which was pulled up at the edges and fastened with rails.
Then the pedestal supports were placed on it, and the panels were laid on top. As @Tolentino already mentioned, the covering is actually of secondary importance. The panels could also be lifted afterwards, although I generally prefer floorboards.
We used this setup above a basement room and the same way as a roof terrace above my dining room; all without any problems for many years.
Is the garage roof currently sealed?

Where the tradespeople disagree on whether insulation is necessary or not.If it is a heated garage, the roof must be insulated. If it is an unheated garage, the roof does not need to be insulated but should be ventilated so that the damp car can dry.
