Abstract
A roofing slab (1) has a roof lead-through in the form of a pipe (2) of adjustable inclination which extends from beneath the roofing slab to a point above it via a correspondingly dimensioned passage hole provided in the region of the vertex of a dome of the slab. The dome has a dome-shaped upper side and a form-fitting hood part (5) associated with the pipe. The hood part rests on the dome in secured fashion by an urging of the pipe, in the region of the lower side of the roofing slab, towards the roofing slab. An advantage from a structural and mounting standpoint is that the pipe (2) be formed in two parts with a place of coupling (K) above the hood part (5). In this way the pipe part (2') which serves the purpose in view can be very easily attached from the outside.
