We had a dormer loft conversion on a Victorian semi done back in 2018/19. Since then we have had issues with damp/wet patches on the chimney breast wall - see attached photo.
We have now had a roofer re-flaunch the chimney, secure the pots and undertake work on the ridge where the flat roof dormer meets the chimney breast. This has resolved many of the issues - 99% of the marks in the photo are now no longer becoming wet during heavy rain (obviously they need sealing/redecorating). In short, we thought the issue had been resolved!
Unfortunately recent rain has seen a very small wet patch reappear - circled in red on one of the photos. It is very small, about 1-2cm in diameter. I also attach a photo of the external patch job/works. This patch falls directly underneath where the ridge falls into the pitched/slate roof, where felt has been torched on (over existing lead/step flashing an soakers).
I would welcome any advice as to what action we should now take to resolve this issue as we just can't seem to fully solve it (although most of issue has now been resolved). Thoughts gratefully welcome!!
