The roof sash (7) is made of metallic flat material with a joint, which forms the edge areas of a support for an upper roof element, particularly for a light dome- or light-band element (6). Another joint is slightly horizontal to the former joint. The roof- and light band sash is integrally formed with the three joints, and the bent portions are made of steel plate by bending.
