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

Abstract: A roof underlay seal (1) for a leadthrough penetrating a roof structure, includes a tubular collar (2) and a flange portion (3) laterally extending from the collar and surrounding it. The collar (2) is attached to a flange portion (3) via a flexible sleeve (4) extending between the collar (2) and the flange portion (3) for setting the upper end of the collar (2) flexibly at a desired distance from the flange portion (3).

Abstract: A device for leading pipes (6) of a solar cell through a roof, which device is characterized by a connecting sleeve having an upper end with an annular cross section, the connecting sleeve being mounted onto the straight-cut upper end of a dome-like collar (2a) of a conventional pipe duct (2) to surround the opening of the collar (2a), as well as by a cap (4) turnably installed on the upper end of the connecting sleeve (3) and provided with a sideward-facing receiving opening (5) for pipes (6) to be led from a solar cell into the building, whereby the receiving opening (5) is sealable around the pipes (6).
