The existing roof comprises an outer structure (2) consisting of wave-form plates with channels (6) and ridges (7) fastened by nails or screws (3) arranged through the ridges into a base (1) on which it rests. Beams (5) are placed in the channels (6) in the roof slope direction on the outer roof (2) top side. The beams are connected with a number of existing fixture components (3) on the outer roof (2) using fixture plates (8) and are made to overlap one another at least at the ends. - The fixture plates (8) are arranged between the beams (5) and fixed to them and to the nails or screws (3). The respective fixture plates have openings for the heads of screws or nails which lock firmly to the plates and thereafter are fixed to the beams. |
