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 ).
