Abstract: An arrangement for openable roofs, especially for glazed verandas and balconies. The arrangement is a horizontal supporting section (10) which defines an elongated guiding channel (11) having an elongated side opening (12), and a horizontal roofing panel (20) which is movable in the longitudinal direction of the supporting section (10). The roof panel (20) has a lateral edge (21) that extends into the guide channel (11) of the supporting section (10). A plurality of separate guiding and spacing members (40) are mounted spaced from each other in a direction of the guiding channel (11), on the lateral edge (21), received in the guiding channel (11), and abuts against the inner wall of the guiding channel (11) to thereby ensure that there is a play both upwards and downwards in the side opening (12) between the panel (20) and the supporting section (10). The guiding and spacing members (40) are designed so as to allow a turning movement of the panel (20).
