Im posting here as 99.9% certain it is NOT a roofing matter.
Have a detached farm house built in 1846 of solid wall construction. All walls are rendered. Roof was removed and relaid in early 2000s.
One gable end has a stack with 2 chimneys, 1 feeds the multifuel stove in the front room, the other is one thats been removed from a bedroom (there looks to be a boxed in RSJ picking up the stack from just below ceiling height up into the loft and out. Both chinmeys have pot cowels so no water gets in.
In winter a few years ago, water started dripping from the registration plate all over the stove (water with some tar colouring) At the time was very heavy rain and persistant. Had a roofer in and said roof was fine as was the stack. In spring, I myself went and checked flashings, all looked good and also resealed in around the covels and sealed the chimneys motar cap. Summer came and we had no rain for a long time, yet if you look at the stack in the loft, you can see the moisture glistening in the plaster.... literally dripping...
Over the last few weeks, the ceilings of both bedrooms are showing damp patches (8-10 foot from roof height) and the stack is now actually beading water its that sodden. I am awaiting a chimney sweep to sweep the chimney and to see if he can tell me if there is a liner etc and also have fitted a vent in the capped chimney in the loft to get some airflow through it.
Last night was heavy prolonged rain and no wetter than before, so as you can imagine im pretty confident its not water ingress, more a really bad condensation or similar, but im lost of what to do
Any ideas of how the hell to stop it?
