Where insulation above the roof void allows the air underneath to stay warm, avoiding condensation, but also allows for an air flow (should one be deemed to be required) through the joists.
11+ Inverted Warm Flat Roof Images. An inverted roof, also referred to as a 'protected membrane' or 'upside down' roof, is form of flat roof in which the waterproofing layer is beneath the thermal insulation rather than above it. Inverted roofs increasingly are becoming a popular alternative to traditional roofs.
Both the warm deck and inverted warm deck construction will have insulation placed above the roof deck. However, once the roof deck (and the membrane) warms up, the condensation will be able to evaporate. Buildingregs4plans flat roof guidance provides information on flat roof componenets, waterproofing, structure, insulation and ceilings.
Systems may be used at a greater pitch where they meet the requirements of this chapter, and materials are adequately held in place.
Warm flat roof fully packed with insulation to prevent any condensation build up.

An inverted/protected membrane roof is a form of warm roof in which the insulation is placed above the waterproof covering (which also acts as a vapour control layer). Inverted roofs increasingly are becoming a popular alternative to traditional roofs.
