A roofing and covering device comprises a set of shaped plates (3), each having respective first (5) and second (7) longitudinal side edges and a set of connection means (9) configured for fixing each plate (3) to a support structure. The cross section of the second longitudinal side edge (7) has, starting from its free border, a curved portion (13) which forms a first cavity (14) facing the respective plate (3); an inflexion portion (15) which forms a housing gap (17) with said edge; a bent portion (19) which forms, with the inflexion portion (15), a longitudinal second cavity (20) facing in a direction opposite to that (C1) of the first cavity (14); a further bent portion (21) which forms a longitudinal third cavity (22) inclined with respect to those (C1, C2) of the first (14) and second (20) cavities. Said longitudinal curved (13), inflexion (15), bent (19) and further bent (21) portions form a shaped element protruding perpendicularly from the plane of the respective plate (3) and with a shape approximately complementary to that of a longitudinal hollow seat (25) defined by the first longitudinal side edge (5) which is bent approximately in an inverted "U" shape and with a longitudinal first rib (27) and an hooking portion (29), consisting in a bending of the respective free longitudinal edge end. The first rib (27) and hooking portion (29) are respectively configured to engage the housing gap (17) and to hook a convexity of the bent portion (19) in a condition of installation of such adjacent plates (3). Each connection means (9) has a coupling portion (31) configured, in the installation condition, to be housed in a volume comprising at least part of the third cavity (22) of the bent portion (19) of the second longitudinal side edge (7) of a plate (3) and bounded by a matching longitudinal portion (33) of the first longitudinal side edge (5) of the adjacent plate (3).
