ROOF CONSTRUCTION
In a roof construction having sandwich elements (11, 12) that lie next to each other in the direction of the slope and consist of a heat-insulating core (14) on both sides covered by metal sheet (15,16) glued to the core, the upper metal sheet (15) of the panels has ridges (22,23) along their edges. The elements are attached to transverse beams (17) by through fastening elements (18-21) that are applied through the upper metal sheet (15) on the outside of the ridges (22,23). A longitudinal cover sheet (30) is arranged to cover both the joint between two adjacent sandwich elements and said ridges (22,23) close to the joint.
