The invention relates to a flashing (1) for a pipe or duct passing through a seamed roof. The flashing (1) comprises a collar (2) at the upper end of which is provided an opening (3) for the pipe or duct, and a substantially flat flange (4) to which the lower end of the collar (2) is joined, which flange (4) is configured to be attached to a portion of a roof, whereby a plane through the upper and lower edges of the opening (3) in the upper end of the collar (2) is set inclined by an angle in a range between 25° and 35° relative to the plane defined by the flange (4). The opening (3) at the upper end of the collar (2) has an oval or oblong shape, facilitating the use of the flashing (1) at various roof pitch angles without the collar (2) being modified. |
