Condensation in chimney stack

[Pocster]

Iv’e got this so called leak on a rental .

Roofers been a few times and basically rendered the stack - change the pots .

Still appears to leak I.e in room beneath damp on ceiling / wall on stack .

Today stripped that part of the roof back .

Bone dry ; no sign of any water ingress .

He’s suggesting it could be condensation coming through the stack inside 🙄

That feasible ? . How do I fix that ?

Roof has no insulation .

Is the stack in use? Open pot or a cowl?

Not in use 

a pot thing I think 

 

there’s no air vent in the stack anywhere ( or if there was it’s plastered over )

Been like this for years and only started showing signs of a ‘leak’ end of last summer .

Here’s the room below the stack

That’s quite a bit of water getting in, and looking at the location I reckon it has to be a flashing or missing pointing on the stack. Had it been part way down the wall then yes it would likely be water from inside the stack getting out but this is too localised. Has to be water on outside of stack or close by that is collecting above ceiling. Have you been in the loft? Wet insulation? Cold water tank in loft space leaking or collecting condensation close to stack?

There is a tank in the loft - but it’s miles away from stack .

Will take a look Wednesday in loft .

Roofer sent me photos - he stripped roof around stack and it’s bone dry .

Roofer now says not condensation but he flaunched neighbors …

[Pocster]

He’s now pissy with me as I haven’t paid him .

3rd time he’s been to this property .

I’ll get good photos Wednesday….
