An improved roofing system is presented comprising a built-up roof (BUR) assembly or modified roof membrane assembly (MRM) which is adhered to gypsum, concrete or composite sheets or panels which have been loose-laid over a roof substrate. This allows the BUR or MRM assemblies to conduct heat to or receive heat from the thermal mass of the loose laid mass-weighted sheets immediately below the BUR or MRM assemblies. The gypsum panels, preformed concrete panels, poured-in- place concrete or composite mass-weighted construction panels which are placed between the BUR or MRM assemblies and the roof substrate causes more gradual changes in temperature between the roof assembly and the roof substrate. Because the BUR or MRM assemblies, which are attached to the loose laid gypsum or the like panels, can move independently of the insulated roof substrate panels with the expansion and contraction concomitant thermal cycling, wrinkles and tears previously associated with the joint lines of the roof substrate panels are practically eliminated. Additionally, the weighted roof assembly of the invention aids in wind uplift protection by providing a floating, moveable mass under the BUR or MRM assemblies by distributing wind uplift shock away from the perimeter edge of the roof and into the interior thereof.
