Inverted roof deck insulation.

The great benefit of inverted roofs is that the insulation protects the membrane from extremes of weather such as frost uv exposure and the expansion and contraction that comes about from summer winter temperature cycles which can be as much as 80 c on some roofs. An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation. Rigid extruded polystyrene insulation has minimal water absorption due to its closed cell structure. One of the main benefits of the inverted roof method is that the membrane is protected by the insulation from the expansion and contraction caused by weather fluctuations such as frost and solar radiation.
