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.

A building includes an outer wall, a roof arranged so as to be orthogonal to the outer wall and inclined with respect to the ground, and a flashing arranged at a boundary between the roof and the outer wall. The flashing includes an attachment configured to extend along the outer wall, a guide connected to the attachment and arranged above the roof, and a water draining portion arranged so as to intersect the attachment and the guide.

A flashing assembly for use with a roof penetrating structure, such as a roof window, in an inclined roof of a building is disclosed. It comprises a bottom flashing element and at least one side flashing element, both of which are provided with a bend portion bent away from the interior side towards the exterior side and forming a water drainage channel, which extends along an edge. The dimensions of the flashing elements are such that the two water drainage channels extend in continuation of each other in the mounted condition of the flashing assembly, and least one of the water drainage channels has a U-shape in a cross-section perpendicular to the edge of the flashing element along which is extends. A method for manufacturing a flashing assembly is also disclosed.

A pipe guard system for preventing damage of piping equipment such as pipe jacks, vent pipes, and the like from environmental elements in roof construction comprising a body member having a top portion, bottom portion, one or more side walls; and a ring configured with an opening to allow the insertion of a pipe jack therethrough.

A through the hole vent pipe fitting seal includes a generally hollow cylindrical main body having an annular flange extending outwardly thereof perpendicular to the axis of said main body. An annular sealing member is positioned against a lower surface of the annular flange. An annular clamping member is movably attached on the main body to clamp the seal around a hole in a construction material on which the fitting is to be mounted.

A ventilation device is supported in at a ventilation opening in a fabric panel of a building in which the fabric panel is supported under tension across a frame. The device includes a lower frame and an intermediate frame with respective flanges that receive a perimeter edge of the fabric panel about the ventilation opening therebetween. A cover is joined to the frames so as to prevent precipitation entering the frame opening while providing exterior ventilation from the ventilation opening of the building through one or more exterior openings in the cover.

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.
