Hi All, just wondered if you might have advice on how to fix what might be penetrating damp. We have some damp patches on the first floor bedroom walls (Victorian terrace), which become a bit more pronounced when it rains heavily. We’ve ruled out leaks. No signs of water in the loft but some cracking in the external wall render (picture attached). No damp patch on the left side of the window so possibly the crack higher up is to blame? The damp patches are on the wall facing outside and the party wall. A damp surveyor looked at the external wall but did not think it was the cause, so not sure what to do next. Any advice gratefully received.

The cracks are something worth looking in to. I don't know where you are, but here in west London the walls would typically be solid 9" walls, Ordinarily, I would not expect them to have been rendered by the Victorians.
Have you spoken to your neighbours? The upper damp patch seems to run downwards. It may or may not be be the case that there is a problem on their side.

Short term... you could use regular decorators caulk. I wouldn't recommend it as a long term fix though.
Looking at your photos, I would expect the tiles to overhang the top of the wall. I am not a roofer though.
Verge tiles look like they let rain on top off wall which will run thru and emerge via easiest route .
