Hi, not sure if this is the right place to ask as it’s not really to do with DIY but just looking for some advice.
Three years ago I had leaks in the bedroom and bathroom. We had the skylight replaced (its seals were all rotted) and the bedroom dormer window re-flashed and re-surfaced (sorry hope that’s the right terms). All has been fine but I’ve just noticed a discoloured patch on the bathroom sloped ceiling which seems to be below the chimney (not used) rather than the skylight. I’ve attached a pic - the bathroom is on the left with the patch marked. Should I go back to the company who fitted the skylight to check it or does it look like the problem is definitely the chimney? Also if it is the chimney does the whole thing need reflashed and if so should cost be shared with neighbour?
