If you put insulation under the decking and between the joists you lower the temperature of the decking and lower the due point thus bringing it closer to the danger point of being in the building. The construction of a warm roof the insulation sits on top of the rafters.

So called because the insulating layer is located above the roof rafters and between the structural supports a warm deck roof results in a temperature for the roof and loft area that is consistent with the rest of the property.
