Which type of tradesperson do I need to investigate leaking wall just under eaves?

And if you're in North London can you recommend one?!

Got water coming into a bedroom between top of window and gutter/eaves. I had the guttering cleared very recently so it's not that.

TIA

Hmm, not sure but I'd probably get a roofer in to take a look as it may be that the bricks need repointing. We had this prob last Oct and it was a roof who sorted it for us
