Roof leak causing property damage – what are my rights?

Long story so I’m going to boil it down to the key points but I would really like some advice on this situation:

I live on the top floor of an apartment block and on Friday late afternoon, the area around my front door and parts of my bedroom flooded with the carpet soaking up all the water in the concrete slabs underneath them. I called the OC manager to arrange the emergency plumber to come out immediately to look at the issue. Two hours later, the plumber finally got here. He spent 2.5 hours looking up and down the building but could not locate the source of the leak. The one place where it was most likely the cause of the issue was a couple of hot water tanks on the roof directly above where my front door area was. There were puddles of water where these tanks sat. Prior to the plumber arriving, the onsite maintenance person had accessed the roof and we both saw the state of these tanks where one in particular seem to be in some sort of overdrive (dripping and venting steam through the drain pipe). After 2.5 hours of him investigating to no avail, I said could you please at least switch off the hot water tanks which look suspicious to which he did.

Early Monday, the builders came out for an inspection on the grounds that this was due to a building defect (I had already filed for a warranty claim). I told them what had happened on Friday, what was done about it, and what I suspected the issue was on the roof. In the process of the inspection, they had to cut holes in the plaster wall in my apartment. They went up to the roof and verified that the hot water unit was indeed the issue because someone had cut and removed some of the piping and the waterproofing element.

It’s Wednesday now and all I’ve heard was that the plumber was going to be out again and they will provide a full report to the OC. This will then get forwarded for lodging a claim against the insurance broker.

I’m concerned because I’ve never come across a situation like this. I’m not sure what I need to do to make sure the damages in my apartment are compensated for adequately and I’m not sure what my rights are here. I feel like I’ve been left out of the whole process and I want to make sure my demands don’t just go into the black hole of this OC manager’s inbox. I don’t feel like there have been adequate transparency around the process and what the next steps are and I get bad vibes that they are going to try to dodge this if they can. Where can I turn to here? Shouldn’t they be involving me in all the reports by the builders and plumbers so I stay informed? Have they breached their duty of care in this instance? How do I make sure what I’m asking for doesn’t fall on deaf ears?
