Condo Building: Neighbor's Patio Leaks into my ceiling - who to call?

In Chicago, IL. Having trouble determining what type of contractor to call for this issue:

During heavy thunderstorms water leaks into, and out of our ceiling. I suspect it is coming from a leak in my neighbor's patio above our unit, possibly from a rotting door frame. I need someone to come out and detect the leak, then fix it / repair drywall. Waterproofing companies specialize in basement floods, and aren't really willing to fix this. I'm also concerned about mold behind the ceiling / walls. Any suggestions on what type of service to call, or recommendations on who to call?

You are probably going to need to have a Remodel - General Contractor for this, because it is probably going to take some opening uo (and later repair and repainting) of the ceiling to track the water stains and to look while using a hose to try to replicate the leak, then possibly doorway work on the patio, or maybe repair or waterproofing by a specialty concrete contractor to seal the leak in the patio - which I presume is actually a concrete deck - or maybe pavers on IRMA membrane roof ?
One thing you mentioned is it occurs only in heavy thunderstorms - so it is quite likely it is not a patio/deck leak at all, but rather a leak around the perimeter because the water is backing up on the roof or under that door because the scuppers or roof drains are plugged or not big enough, or alternatively that the water is coming in at that time only because it is being strongly wind-driven. Or a leaking drain seal where a roof drain penetrates the roofing. That might give a clue to the source location, but normally you end up having to track the leak from below up to where it is actually occurring - and many times takes a couple of tries, either because you fail to find the exact leak point the first time, or because there are multiple leaks all draining to the same place.

Of course, this is also going to have to be coordinated with your neighbor. Actually, under common condo agreements, it might be incumbent on HIM to stop the leak by whatever means is appropriate, because generally leaks from one unit to the other have to be repaired by the one owning the location where the leak (roof or deck or pipe or whatever) originates, so you might be off the hook for the repair - though it then means getting him/her to actually get it fixed correctly. OR the deck might be treated like roof and siding are for some condos - as common property and common maintenance responsibility, so contrat cosxt is shared amongst all building occupants, or paid for out of a common condo association building fund.
