Good morning, I'd appreciate some advice. Back in January of this year, I hired a roofer who told me the ingress of water to my attic was caused by a lack of valley between roofs (I live in a mid terrace Victorian property which is 3 storeys), that the chimney required soakers, repointing and replacement of roofs.
Months later, the roof failed. Hired a new company who inspected my roof and informed me that I needed a new roof entirely as all the battens were rotted through, the valley didn't extend to the chimney, most of the slates needed replacing and flashing was inadequate, also no soakers.
Work commenced and finished but water is still accessing my building through the roof. I've attached two pictures. The first is of the attic, the chimney is above that area. In the 2nd picture, that is the room immediately below and water is accessing the cavity wall and tracking down.
The roofer restripped that section of the roof, checked all the soakers, flashing, etc.. and could not find the source of the water ingress.
I have no idea where to go from here and any advice would be greatly appreciated. The only thing left to do is repoint that chimney - I was informed by the company that it was extremely unlikely that was the issue of vulnerability.
