Hi, for at least a year there has been a bulge on my bedroom ceiling (see photos).
It doesn't feel wet or damp but i can push it in a bit. Think the ceiling is artexed (house is 10 yrs old). Because i've been prodding it some of the artex has now flaked off (photos show before and after!) and behind the artex it feels almost like paper which is still a bit soft but can only be pushed so far before the surface is hard again (I'm assuming this is the plasterboard).
My Dad went up on the roof but couldn't see anything obvious. Also went in the loft, the bulge is probably under the insulation but is in an awkward area where the roof meets the floor so can't really get close to see it properly.
Do you think it could be something to do with the ames taping rather than a leak as it does not feel damp?
