New builds require flat roofs to be “warm”. So what is the difference between warm and cold roofs?
Cold Roofs
Cold roofs are where the insulation is installed below the deck of the roof, normally between the joists.
Warm roofs
Warm roofs are where the insulation is installed above ‘on the outside’ of the deck of the roof and then an additional deck is added. This prevents moisture from the air in the room condensing when it hits the roof causing possible mould and damp issues
