Condensation Mold or water leak in roof or?

[Jeff543]

This is the bedroom ceiling, I must admit the upstairs windows do get full of condensation often and lately. Is this ceiling stain it from a leak through loft? I've had a look with a torch and doesn't look like there's any big holes in roof. Oh yeah no one in the house smokes

you would need to see if the board, from above, is wet or shows staining and then see what's above it, to rule anything out up above.

But i don't think there's any water pipes up there.

It's just to rule out if it's getting wet from above, say a drip through a cracked tile or something else, if not then if there's nothing down below, be it condensation or the like, then stain block it and paint over it and forget about it until t appears again, if at all.

Thanks and if that was the case I assume that in heavy sustained rainfall I'd be able to hear or see a drip?

That stain is typical of drip from above- put a sheet of polythene in the loft, next time it rains see if the sheet gets wet. May be a combination of wind and rain causing a very intermittent leak ..

I just had a bout of heavy rain and i shone my torch in the loft , i couldn't see any drip. Is it possible that it is internal mold due to not opening windows when condensation is high and the windows are steamed up?

Anyway got any tips for getting rid of that stain?

stain bloc or any oil based matt paint

Are'nt you supposed to sand it down first?

 

[Madrab]

Nah, not really, won't do anything for a stain, that'll have permeated all the way through, all you can do is cover it, use a matt and then roughen it and you may be able to emulsion over it

I suppose i'd have to do the whole ceiling so it all blends in?

No big holes??? Does that mean you do have some small ones?

The roof's all been done by a roofing company since. Gables were rotted unbeknownst to me.

depends on how old the current paint is I guess, if it's still nice and clean then a new spot of emulsion shouldn't look too out of place.
