Penetrating rain

[Babaganush]

Hi there.
We have damp in one of the alcoves in our kitchen (party wall, end of terrace). The damp expert thinks it’s due to the roof that basically needs replacing. However, we do think the cause is cracks in between our wall and the neighbour’s.

I’ve attached a picture. The wall on the left is our wall which has (unfortunately) been painted. The one on the right is the rendered neighbours’ wall.
What do you all think and what can we do?

Please take a wider pic, all the way up to the roof, and all the way down to the ground. Show the roof overhang, gutters, downpipes and any protrusions.

Also show the indoor walls of the adjacent rooms, upstairs and down, ceiling to floor.

I’ll do the outside pictures later on. Here’s the damp.

Originally there was a Downpipe (from the conservatory) that was draining water very close to the wall and we had it extended far away from it. Unfortunately, we have not seen any changes. Then we had a new roof, reporting of the chimney, change of the cracked coping stone etc etc. we still think it’s the outside wall.

Pics of roof please.
