Funny roof leak?

[neds]

Hi all, hope someone can help!

I'm not in the roofing game so this has got me baffled. Got a weird potential leak in my house which is a mid 1940s. Concrete tiles no roofing felt.

So on one of the rooms closest to the gable end its where the room goes into the ceiling of you know what I mean kind of slopes in I guess so they could save money on bricks and not go full height! Anyway where the slope is there is a damp patch seen the pictures there seems to be some mould forming too, but mainly damp going into the loft can't see anything as obviously this is where the ceiling is tight against the roof timbers. A couple of rooms have this Problem and its low down to the eaves which you can't get to from the loft to check for problems. Anyone Seen this before? Any advice most appreciated.

Unfortunately, its a classic location for water damage due to leakage and/or condensation.
You have no felt so you wont have insulation.
Go in the loft above the water signs and examine everything for water penetration or excessive condensation.
Go outside, up a ladder if possible, & examine the external area - look closely in the gutter and just above it? Any chimney stack nearby?
Take loft & external photos and post on here.

Cheers bud, will take more pictures from the outside couldn't see any obvious slipped tiles from ground level. So I guess on a normal roof without the eaves cutting into the ceiling you wouldn't notice it as much. Would eave trays help in this sort of situation or make things worse? I know it's not really for use with roofs without felt...

I dont know, I doubt it, unless the tile or slate is set back from the gutter?
But take photos and I'll be able to comment better.

Ok thanks. So the tiles are slight out the gutter and no chimney near the leaks. Will take some more photos.

If it gets worse when it rains, its a leak. Otherwise its condensation

Might be both.
