Gyprock Gurus

I noticed a ceiling problem upstairs the other week and was wondering if what I've worked out makes sense. Two storey Brick and Tile house and the center upstairs looks like this.

See the cornice is pushed down both left and right. That is a join in the gyprock boards along a truss. Put a builders level at either side and it rocks. Put it in the middle and it's flat. The cornice in each room either side is also sagging to some degree and the level rocks there too.

I can't get on the roof to look, it's too high, but I put a canon on a stick with a long USB lead, stuck it out a window and took this shot.

Obviously there is a busted tile sitting in the channel and I'm sure that will make a decent QLD downpour overflow the channel. That tile is very close to the truss in question.

Will water swell gyprock and cause the issue we are seeing here? There are no water stains at all.

I have a roofer coming in a couple of weeks to do a report and insurance is event driven so I'm hoping a busted tile causing a water leak is the event.

Sound like a plan
