Hi,
It's time to redecorate the kitchen, and I'm looking with a critical eye at where water came through the ceiling last year. It's caused a small sag in the ceiling about 12" x 2".
I've pic a picture here :-

It actually looks as if it is the Ames which covers the seams of the plasterboard has bubbled off, so you might be able to get some wallpaper paste or PVA glue behind it and stick it back up. Because of the shape and size of the bubbled section, you will have to cut a line across it with a modelling knife and let the section flap down. This will let you get a dawlop of paste on the back and then you can press it back up until it sticks.
Mix your paste quite thick or liberally spread the glue and allow the moisture from it to soak in and soften the tape, then stick it back in place. You might have to hold it for a minute or two, so make yourself comfortable and secure before you start. Then it should be just a case of painting it the following day after it has cured off.
Good luck with it.
I had similar in a bedroom in my old house, when the cold water tank overflowed (worn washer) and the overflow pipe hadn't been solvent welded properly and dripped water onto ceiling. I had two problems, unglued seams and slight sag of plaster board where water collected.
I glued back the seams using PVA glue, held in place using a foam pad on end of length on 2x2 wedged between the floor and ceiling to apply pressure.
I bent back the sag using the same bit of 2x2 and foam pad/wedge arrangement, PVA'd the back of the plasterboard in the loft and poured on a mix of PVA and plaster and let the "blob" set. Let dry, removed wedge etc, filled slight cracks in ceiling and repainted. Would never have known there was a problem unless you went into the loft and lifted the insulation.
All went to waste, as 7 years later water tank split, emptied contents, bought ceilings upstairs and upstairs down and no amount of PVA an plaster could fix that.
