FIELD: building structures, particularly roofs with plane sloping surfaces.
SUBSTANCE: composite mansard roof comprises composite panels including load-bearing frame made as cold-formed steel beams having thin-walled channel cross-sections of E-shaped profiles. The beams are provided with stiffening ribs transversal to beam walls. The beams are connected with each other through outer wall of rectangular and corner panels along perimeter thereof. Two grooves receiving rubber packing are created in upper panel parts and located from outer sides thereof. Lower panel parts have orifices. Heating layer is arranged between two steel sheets. Lower sheet is perforated and is rigidly connected with lower stiffening rib surface. Upper sheet is rigidly connected to upper beam flange and has polymeric coating. The panels are secured in longitudinal and transversal directions.
