Hi
We have a flat roof at the very top of our house in a loft conversion. It is torched on felt.
I'm pretty sure somewhere around the chimney breast, where the flat roof meets the chimney breast, or on top of the chimney breast, is a leak.
It is leaking onto the plaster board ceiling, not much water, but enough to be annoying.
We've called out
- a specialist roof repairer, who said he was going to seal the area, then coronavirus happened
- a roofer, he seemed alright, he burned felt on to the area that he said wasn't properly done. It still leaked, he came back and covered it in cromapol.
After the second time he came, and covered it in cromapol, the leak did lessen in terms of the amount and frequency of the dripping leak.
So I went up there and smothered it in cromapol. Covering a wider area.
But... You guessed it... It is still leaking
I'm at my wits end, as I want it fixed, but I don't want to keep paying for someone to just have a go.
I found websites of specialist who find leaks. This sounds expensive, is it?
Also, will a leak detection specialist actually find the leak?
UK leak detection is second to none in roof and balconied leak detection. We are able to identify the leak location or penetration points to surrounding structures of your flat roof or balcony, by using the latest leak detection equipment and techniques, including… Wet testing method: First...

Hoping we might have some roofers on the forum.
EDIT 1
This is how the roof originally looked, we have been told (by you guys) that's it's 'Join City' - with lots of joins and insufficient flashing.

EDIT 2
We had a roofer who "burned on" all the joints around the chimney. The leak still kept coming.
Roofer's second attempt was to cover it in Roofing Acrylic Paint. It slowed the Leak, but did not stop it.
We then did a second coat of Cromapol, acrylic roofing paint.
You can see the whole chimney is covered in Cromapol.
The bit in front of the chimney is covered in Crompaol.
A bit either side of the chimney is covered in Cromapol.
ADVICE PLEASE:
Should I
1. Try and get someone to add flashings, or has that ship sailed due to the Cromapol.
2. Go up there and cover more area in Cromapol - if so where?
I can see areas where water is pooling. I an see joins on the wall that i could maybe cover. What do you think?
This leak is really really annoying - so advice is much appreciated. Thanks
I would be grateful for opinions:
Here is what it looks like now.
Here is what it looks like now, took this today (using a GoPro on a stick) an hour after it rained
