My place has a two story extension on the back with a conventional flat roof. There is clearly no insulation in the roof space because the ceiling is cold to touch and the radiators cannot heat the room adequately. The ceiling is low and the door only just clears it. I was hoping I could line the ceiling with insulation material that can be skimmed with plaster and painted - the tricky thing being that there is only 25mm clearance above the door.
Any recommendations?
I’d suggest a warm roof.
[Pay someone to] strip off the roofing felt, clad the flat roof in 200mm of solid foam insulation, felt over the lot.
Obviously that’s the abridged version.
