Damp patch on the kitchen ceiling....

[ChatterMonkey]

Its always been there, its dry to touch but it is slowly growing...

Its directly under where the bath is upstairs, but also on the outside wall, and we are aware of the roof needing repair/replaced....

How urgent would you say this is? And which of the three reasons is more likely the cause? Or is it an expensive combination of the 3...

It's pretty urgent. If you leave issues like this you might end up needing to rip your ceiling down and having a new one.

Take the bath panel off and have a look, there's probably a leaking pipe or loose connection. If it's bad enough to show through on the kitchen ceiling then it needs sorting as soon as possible.

Habe sent dp a pic of it, hes at work atm but will be home soon and can take a look with me.

Frustratingly, im working from home and sit in the kitchen, with this patch directly in my eyeline so can't concentrate on anything else now!!

Im hopeing it is just a leaky bath, as surely that'll be easier to fix than roof or outside wall issues.

Roof is on the to do list and we are saving but will obviously need to speed up the process if its the cause of the damage.

My bet is that your bath waste pipe is leaking. They’re usually made of plastic and basically rot away after a number of years. It’s an easy DIY replacement, if I’m right - provided you have access via the bath panel.

Leaking pipe from bath is the easiest one to rule out. We had something similar, but it was on the wall as well - luckily it was a plastic fitting and I tightened it myself. If it's not the pipe, it might be worth seeing if you can borrow a small electric saw, so you can check under floor/possible torch on far wall to see if that helps.

If the roof is leaking, I'd expect some extensive damage to the ceiling/wall in the room above (we've had a leaking roof which has been a nightmare to sort and been going on a few years!).
