A roof tilt having a lead-in hole (7) for antenna cables or other elongate elements of rooftop fixtures comprises a tile body (1), a pedestal (4) integrally formed on the upper central surface of the tile body (1), a nozzle (6) integrally formed on the pedestal (4), and a pipe joint (9) having a base (10) and a bent leading end (11). The pedestal (4) has a bolt hole (5) bored therein so as to extend through the tile body (1) for inserting an anchor bolt (14) thereinto to fix the tile body (1) to a roof board. The nozzle (6) has an annular rib (8) formed on the upper periphery thereof and a nozzle hole (7) formed therein so as to extend through both the pedestal (4) and the tile body (1) to serve as the leading hole. The base (10) of the pipe joint (9) is adapted to be fitted around the nozzle (6) and to be fixed to the nozzle (6) by a bolt (12) screwed therein and brought into collision contact with the periphery of the nozzle at a position below the annular rib (8). The bent leading end (11) of the pipe joint is directed towards the upper surface of the tile body (1).
