摘要： A venting device (10) comprising an annular wall (11), an annular flange (14) connected to the annular wall (11) and extending away from the annular wall (11) in the radial direction, and a cup-shaped member (16) connected to the annular wall (11). The cup-shaped member (16) defines a cavity with a peripheral edge (19) facing away from the flange (14) in the axial direction. The cup-shaped member (16) having a venting hole (20) allowing air to pass through the venting hole (20). the cup-shaped member (16) is invertible so that when inverted the peripheral edge (19) faces towards the flange (14) and so that a sheet material (100) such as an underroof can be accommodated between the flange (14) and the peripheral edge (19) with the peripheral edge (19) in sealing contact with the sheet material (100).
