Damp/mould issue
I have a question about an old loft conversion in a property we bought.there appears to be a dark mould growing on the side of one of the main beams with runs the length of the loft conversion ceiling. The beam was painted white by the previous owner and I imagine it must form part of the main structure of the roof. Is this likely to be an issue with the roof i.e slate or could it be an insulation problem (if there is any) I can't see as it's all been overboarded. Any advise would be appreciated.

You have a cold spot where there is no insolation on the top of the timber so the timber that is exposed in side is colder than the temperature in the room that makes condition build up on the timber that makes the mould grow
I have seen this before and It could be the insulation touching the roofing felt and not allowing any air flow so can cause damp or a broken slate or roofing tile cheers jlb roofing
yes that can be damp from leaking roof which will cause timber wrott in the future
Whoever has installed the previous insulation had tucked it into the eves and hasn’t give the insulation any room to breathe therefor it will make the insulation to sweat and damp would occur from this and go onto your walls
not suffeciant insulation
and lack of ventilation
