My daughters bedroom has had and has a damp problem, her room is an extension, and has three outside walls, and a flat roof.
There has been a damp patch appearing down three corners of the room, literally like water has run down each corner. The roof is dry, and in good condition, I have had a roofer on there to see what the problem was, and he said that the cement inbetween the coping stones had worn down, so he he filled them and that was that.
But, no change, teh corners are still wet, condensation on windows, and mould forms on walls and cupboards, what do i do?
I have had two roofers take a peek and both said same thing, coping stones, but no change....
I am trying to sell my house at min and this problem needs to be sorted, and i just dont know what to do next.
Please help with any advice, I have tried to clean mould off, it goes, but is back within a week or so.
