Abstract: A roofing structure for buildings, and more particularly a roofing assembly having high resistance, especially for use with roofs of residential and industrial buildings. The assembly comprises a plurality of sheet panels to be interconnected along side edge portions shaped to define a first longitudinal projection facing laterally outwards, and multiple mounting brackets to be anchored to a roof. Each bracket has at least one longitudinal groove to house in a snap fit relationship the first longitudinal projections of adjacent panels, so that the first longitudinal projections and the groove have opposing upper surfaces at least partly flat and substantially parallel or slightly inclined, in order to enhance the retaining action of the brackets and increase the separation load causing the separation of the edge portions from the brackets.

Abstract: A roofing structure for buildings, and more particularly a roofing assembly having high resistance, especially for use with roofs of residential and industrial buildings. The assembly comprises a plurality of sheet panels (2) to be interconnected along side edge portions (4, 4?) shaped to define a first longitudinal projection (5) facing laterally outwards, and multiple mounting brackets (6) to be anchored to a roof (T). Each bracket (6) has at least one longitudinal groove (7) to house in a snap fit relationship the first longitudinal projections (5) of adjacent panels (2), so that the first longitudinal projections (5) and the groove (7) have opposing upper surfaces (8, 9) at least partly flat and substantially parallel or slightly inclined, so to enhance the retaining action (R) of the brackets (6) and increase the separation load (p) causing the separation of the edge portions (4, 4?) from the brackets (6).
