Various roof vent adaptors are disclosed. The roof vent adaptors can be used to seal penetrations on buildings, such as vent penetrations on metal or non-metal roofs. In various embodiments, the roof vent adaptor includes a sealing member, an outer securing unit and an inner securing unit. The roof vent adaptor can be secured to the roof to provide a generally liquid-tight seal around the roof vent, thereby inhibiting or preventing water intrusion into the building.

A kit for flashing a mount of a photovoltaic assembly on a surface includes a flashing assembly. The flashing assembly includes flashing that extends across an interface of the mount and the surface when the mount is attached to the surface. The flashing includes a bottom surface and a top surface. The flashing assembly also includes tape attached to the bottom surface of the flashing. The tape includes a first attachment area and a second attachment area. The flashing assembly has a first configuration in which the first attachment area is attached to the flashing and the second attachment area is unattached, and a second configuration in which the first attachment area is attached to the flashing and the second attachment area is attached to the surface. The tape is movable with the flashing as an assembly when the flashing assembly is in the first configuration. The first attachment area and the second attachment area positioned on opposite sides of the tape such that the tape extends between the surface and the bottom surface of the flashing when the tape is in the second configuration. The kit also includes a container defining an interior space to receive the flashing assembly.

A roof mount assembly mounts a structure to a roof having a rafter and a substrate supported by the rafter. The roof mount assembly includes a piece of flashing positioned on the substrate. The flashing includes a first surface, a second surface opposite the first surface and an aperture extending through the flashing. A fastener extends through the flashing aperture. A bracket is connected to the flashing via the fastener, and the bracket is sized to support at least one roof-mounted structure on the roof. A seal is positioned between the flashing aperture and the fastener. The seal is sized to form a water-tight seal with the aperture to inhibit flow of fluid through the aperture. The seal includes a first portion and a second portion, in which the first portion is positioned to abut the flashing first surface and the second portion is positioned to extend through the aperture.

The sealing device for construction comprises a duct and a linking member mounted around and rigidly connected to the duct, wherein the duct comprises: an axial main portion around which the linking member is mounted, a radial bead formed on the main portion and extending radially outwards, and a distal end portion extending the main portion radially outwards and which is axially facing the bead to form therebetween an outwardly radially open annular mounting slot, the distal end portion extending radially beyond the bead, the main portion, the distal end portion and the bead of the duct being made of one piece, the linking member being mounted in the mounting slot and gripped axially between the bead and the distal end portion of the duct.

The present disclosure provides sealing devices and construction methods thereof. The sealing devices include a duct having a main axial portion, an intermediate annular portion facing the main axial portion, and an annular end portion facing the intermediate annular portion. The intermediate annular portion and the end annular portion are connected by an annular fold so as to form an axial annular mounting slot that is axially open opposite this annular fold. A connecting member comprises a radial plateau and, around a through-opening, an axial annular mounting portion. The axial annular mounting portion of the connection member is engaged and grasped in the axial mounting slot between the intermediate annular portion and the end annular portion of the duct.

A tool for forming flashing is disclosed. The tool includes an elongate rod member, a handle member disposed on a first end of the rod member, and a spade member on a second end of the rod member opposite the first end, wherein the spade member includes first and second spades symmetrically disposed and having a gap therebetween.
