  • Patent number: 7059086
    Abstract: The present invention relates to a flashing member for a roof-penetrating structure, comprising a first flashing portion (2) adapted to provide a seal against a roof and a second flashing portion (3) adapted to provide a seal between the first flashing portion and the roof penetrating structure. The first and second portions (2, 3) are interconnected in the mounted state, so that the flashing member provides a seal between the roof and the roof penetrating structure. In the state of delivery, the first and second portions (2, 3) of the flashing member are interconnected with each other in sliding engagement allowing the relative position between the first and second flashing portions to be adjusted during the mounting process. Adjusting means may comprise a first folded over part (11) creating a first narrow fold (13) on the first sheet portion (4) and a second folded-over part (14) creating a second narrow fold (16) on the second sheet portion (6), the two folds (13, 16) meshing with each other.

  • Patent number: 6503601
    Abstract: A deformable roof flashing material for use in connection with skylight windows and roof penetrating structures is provided. The roof flashing material includes a sandwich construction with two outer layers of metal foil and at least one intermediate layer positioned between the outer layers. The material has, in at least one direction, a continuous wave form. At least the intermediate layers adjacent to the outside layers are made from a non-adhesive resilient material. The wave form is formed in such a manner that it maintains the mutual positioning between the outer layers and the adjacent intermediate layers by friction.
