Hello,
We have a bungalow with a dormer roof which has vented soffits in cold weather the soffits allow cold air into the roof so the edges of the ceiling are colder and moisture condenses on these cold areas which leads to mould. I have recently fitted a loft hatch to allow access to the roof space and have seen that there is a membrane on the top side of the plaster board ceiling which seals the moisture in. There is insulation in the roof which has been pushed out to the roof which I assume prevents ventilation which the soffits are intended to provide.
My question is what can I do to prevent moisture condensation at the ceiling edges? Do I actually need ventilated soffits can I cover most of them with insulation and use something like this in a few sections
