  "definition": "A Protected Membrane Roof, an inverted roofing assembly where the waterproofing membrane is installed directly on the structural deck, beneath the thermal insulation. The insulation is then covered with a layer of ballast, such as gravel or concrete pavers, which protects the membrane from physical damage and UV degradation. This design keeps the membrane at a more constant temperature, extending its service life.",
