ABSTRACT:
A ventilation element (1) for roofs having a vent cap (3) to be located in the ridge, slope, or arris region of the roof and having at least one elastically flexible sealing member (7) which adjoins the edge area (4, 6) of the vent cap (3). According to the invention, an optimum seal between the vent cap (3) and the roofing material is ensured by the fact that the sealing element (7) is made as a hollow body (10) with a preferably roughly pear-shaped cross section, which is closed in a free edge area and in its area which is adjacent to the edge areas (4, 6) of the vent cap (3). Slits (41) can be provided in the hollow body to allow the egress of air from the roof, in part, through the hollow body without adversely affecting its sealing function.
