The ventilation cap (1) for roofs has a fastening strip (2), at least one outer sealing element (3) and at least one ventilation strip (5) provided between the sealing element and the fastening strip. The sealing element is adapted two-dimensionally to the profile of the roof covering element. The angle included by the fastening strip and ventilation strip on one side and sealing element on the other side is slightly smaller than as determined by the inclination angle of the roof. |
