I have a very small almost flat roof on the back kitchen. The roof is thin (felt with wooden structure, no joists etc for air ventilation) the ceiling under it is light plaster or artex. No problem with wood rot or moisture accumulation or leaks, since any heat goes straight out through the roof!
Question is whether upgrading of the kitchen ceiling to retain more heat with insulated plaster board with Vapour barrier etc would cause any wood rot problems etc on the existing structure?
