What provisions are there for drainage?
Once built a raised deck with flagstone paving over wood framing and membrane. We put a large area drain right in the middle, which did not please the homeowner until we asked him where the water should go...?
quarter inch per foot slope down to front of deck where there is a drain that ties in to existing irrigation system however there are some low spots in the slab and capstone where water collects
Even on a waterproof roof system, ponding water is a gauranteed leak.
And concrete is far from waterproof.
