On flat roofs, a ‘warm roof‘ is one in which the insulation layer is laid on top of the roof structure. This results in the structural deck and its supports being at a temperature closer to that of the building’s interior. This is as opposed to a ‘cold roof’ in which the insulation is below, or within the roof structure, and so the roof structure is closer to the outside temperature.
