A warm roof has the vapour barrier and the roofing insulation installed above the roof deck and beneath the waterproofing. This keeps the air temperature stable and requires no further ventilation.
In a cold roofing installation, the insulating layers are beneath the roof deck and above the ceiling or roof void. This type of installation requires additional ventilation to maintain air temperature stability and reduce condensation.
