Bulges in ceiling where wall meets ceiling

becciboop

Hi all
There are bulges in the ceiling in the bit between the wall and where the ceiling meet. The bulge has a tiny crack running through it, anyone have any ideas about what this is? There is no dampness. A new roof has been fitted recently.

Thanks

Depends how big the bulge is, small bulge could be where some fixing have been used, large bulges could be the weight of the new roof/somthing structural.

I'd get it checked out independantly.

It's a small bulge and runs from one side of the ceiling to the other, what could it be if it is structural?

i'm confused, first of all it was where the ceiling and wall meet, now its across the ceiling wall to wall!

is it inline with joist? one of the workers possibly stood on a joist while in the loft, caused the ceiling to crack, or just the plaster board trodden on and has not sprung back?

need to get in attic and investigate or take a photo and report back.

There can be small bulges in a ceiling where the plasterboards meet. Bear in mind that a plasterer has to get a flat ceiling by eye. Also, the joists might not be exactly straight, so the ceiling could appear wavy. That is the case in one of my rooms. A ceiling crack is commonplace. All it takes is some movement in the joists, due perhaps to a careless person bouncing around in the loft, or movement of the roof in high winds. Someone walking in the loft should not in itself open cracks. I had some cracks in my new sitting room ceiling, and I suspect it was due to electricians in the loft. Perhaps two people was too much, or perhaps one of them was careless. The project manager was very fat, so maybe it was him. I filled the cracks, and many months later they have not reappeared despite my going in the loft numerous times.

Sorry for the confusion, I'm not good at describing things like this.
Here is a picture....

It looks like the ceiling and top of the wall (above the picture rail) has been papered in 1 length.
The bulge would be caused by the paper shrinking a bit and pulling itself away from the wall/ceiling.

I agree with plum. Its not a plaster bulge its the paper and its because there has been differential movement between the ceiling plaster and the wall plaster. Inevitably the part of the paper in the angle will not have been stuck down as well as the rest. Its not unusual and IMO this is not structural.

Thanks, I thought it was something more sinister. Does it look ok then?

Got the same sort of thing in places in my house!
Doesn't look great but nothing to worry about.

Ok phew! That's good. What should I generally look out for when thinking about structural damage? There are a couple of cracks in the back bedroom but nothing deep.

Thanks all.
