hi,
I have recently bought a 1930s detached house which I am renovating. When we stripped back all the wall paper the tops of the upstairs chimney breasts, they both had signs of damp. The house has has loose rockwool insulation retro fitted to the cavities and also has about 300 mm deep rockwool in the loft.
The damp got worse as we got closer to winter and is now about 1.5m down from the top of both the chimney breasts. Also during the really cold spell we had a lot of condensation in the loft space.
I had the roofer check the chimneys and he is happy the chimneys and flashings are both ok.
I was thinking of fitting some slate tile vents and an air brick at the top of the gable end to ventilate the roof space.
Any advise on the cause and remedy for this would be much appreciated!!
