Damp on ceiling in bathroom

[mishel02]

Hi, I have a damp patch in my bathroom on my ceiling in the corner. It is the corner of the house and I had the gutters replaced about 6 months ago and the ridge tiles re-bedding to try and sort the problem out.

It has been like this for about 3 years and I cleaned it off with mold spray and painted with mold/damp paint but it comes back every 6 months. I did have virtually no mortar on my ridge tiles so might have been letting water in. But since I have fixed this its happened again, any ideas please

Thanks

Its condensation!

There seems to be a distinctive shape to indicate that there is a cold spot above - missing insulation?

do you think I need to get in the loft and have a look where the spot is? I wasnt sure if water had come in the corner where the ridge tiles were lose but thought it would have dried up by now

thanks guys

How old is the house did it once have a chimney in that corner.

The pattern does not seem like that from a roof leak. Go in the loft and look

the house was built in the 1950s and there has never been a chimney there, im going to get up in the loft this week and fight past all the junk lol

I reckon that's where the shower is and no external vent

Does the bathroom have an extractor fan?

Does it have an 'over run timer' to last 20mins after the light has been turned off?
