In the top room of our victorian terrace, we have a mouldy-damp patch at the top of the chimney stack in the room.
There's a photo link below here:

When we moved into the house over 2 years ago we thought it was a historic issue and had the room re plastered. However the damp patch came through again. So at the start of 2013 we had a roofer in to check the chimney stack, replace tiles, re point etc etc. They did a comprehensive job (I hope!) and we thought that we'd cracked it. However it's still there. Probably worse then before.
I'm thinking about buying an expensive dehumidifier to really try and dry the room out completely and check that it's not just trapped moisture in the bricks or plaster.
Is this a good idea?
Any other advice for this kind of issue? I don't want to have to pay for yet more works on the roof and they seemed to think there weren't any leaks or issues.
I guess the other thing is to stick a load of sealing paint in the area and re-paint the wall and see if that solves the issue.
