    Abstract. The results of the conducted studies of heat-insulating mineral wool plates in the roof structures with waterproofing PVC-membrane carpet, bitumen-polymer roll materials (BPRM) laid on the thermal insulation dry (with mechanical fastening to the supporting metal profiled flooring) and from the BPRM glued to the surface of thermal insulation are given. The dependences of the elastic limit and the elastic modulus of mineral wool plates on the initial parameters of compressive strength in the case of 10% linear deformation are obtained. It is established that the most destructive impact of the pedestrian load is exposed to the roof structure with a heater of mineral wool plates and a water-insulating carpet of PVC membrane, mechanically fixed to the supporting flooring. Tests have shown that increasing the thickness of the PVC membrane not affect the residual strength of the mineral wool plates. Higher quality of the roof is provided by the materials of the water-insulating carpet of the adhesive system with the use of BPRM with mechanical fastening of the lower and gluing of the upper layers or with gluing of both layers of rolled material to mineral wool slabs.
    Key words: roof, pedestrian load, mineral wool plates, compressive strength at 10% linear deformation, PVC membrane, bitumen-polymer roll material, limit of elasticity, modulus of elasticity.
