Leaking flat roof, one year old!

So, life's latest drama.  When it rains, it pours.

And it certainly was pouring a  few nights ago here in Surrey.  My front flat roof over the garage and bathroom, merely one year old, started leaking during heavy rain.  Its under guarantee, so roofer is coming tomorrow to hopefully sort it out.  One year old and leaking, can't believe it.

Unfortunately, I have artex roofs.  So artex on plasterboard.  They haven't really been an issue since I've lived here, but if anything like this ever happens you have to take it into consideration.

The damp section of the artex looks undisturbed and firm to the touch so I'm guessing its not a concern.  Just needs drying out.  However one damp corner in the downstairs WC is a little soft.  My finger actually went through one section, so I put some polyfilla in the gap and am running a dehumidifier. 

Should the plasterboard go back to its normal consistency when dry?  Are there any other consideration with regards to the artex?

I'm guessing just leave to dry thoroughly, but thought I'd put the question out there.

Have attached lovely pictures of the leak in the garage.

Plasterboard, if wet for prolonged periods of time, turns to mush. The occasional damp patch that is dried out fairly quickly shouldn't be a problem. If the ceiling starts to sag and remains soft/spongy where it got wet, the plasterboard can be cut out and a patch inserted.

In your shoes, I'd leave it to dry out and reassess once the roof has been fixed.

Thanks, yes that makes sense.  Have had a minor bathroom leak that caused the kitchen lights to trip the RCD, no issues with the plasterboard/artex.  Just dried out.

So the plasterboard with artex is probably going to have to be replaced.  Though the artex looks intact, the outer surface is starting to separate from the plaster.  So for safety, I'm getting it taken out by an asbestos removal company.

Roofer still hasn't sorted it out, nearly 2 weeks later.  He put some sealant up there, but it continued to leak.  I went up there and had to seal it up myself.

Under his guarantee, should he bear the cost of repairing the plasterboard?
