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.

An expandable flashing device comprises first and second pieces of flashing material that overlap one another with hems or folded edges located on opposite lateral sides of the pieces that hold the pieces together, yet allow the pieces to slide or shift with respect to one another to selectively change the length of the device. In a first stowed position, the pieces overlap one another and in an expanded second position, the pieces may be pulled apart to increase an overall length of the pieces. The maximum length of material that overlaps between the pieces is defined as the overlap range. The overlap range defines the range to which the device can be shortened or lengthened to fit a particular installation. A flashing system and a method of installing flashing are also disclosed.

A roof vent system includes an attic flange member for installing adjacent a roof sheathing inside an attic, a roof skirt coupled to the attic flange and installed on an exterior of a roof, and a roof transition duct having an exterior opening that permits the ingress and egress of air through the roof vent system. The roof transition duct is coupled to the roof skirt and defines an upper end of the roof vent system. A grill is positioned over the exterior opening.

Headwall flashing and sloped wall flashing, each having a ledge, where the ledges are designed to meet at an outside corner of a roof protrusion comprising a headwall and a cheek wall, the headwall flashing being configured to abut a face of the roof protrusion and having a downwardly-angled ledge that ties into the ledge of the sloped roof flashing, which is angled such that it forms a consistent ledge for installation of siding up a cheek wall, despite the siding creating a shimming effect that would typically result in a stepped appearance and misalignment thereof.

A fire and water resistant, integrated wall and roof expansion joint seal system includes an expansion joint seal for a structure. The seal includes a central portion having an underside and at least one central chamber disposed around a centerline, a first flange portion extending outwardly from the centerline and a second flange portion extending outwardly from the centerline in a direction opposite the first flange portion. The system further includes a joint closure. The joint closure includes a core and a layer of a water resistant material disposed on the core. The joint closure further includes an end portion configured to match and integrate with the underside of the central portion to form the watertight, integrated wall and roof expansion joint seal system. A fire retardant material is included in the core in an amount effective to pass testing mandated by UL 2079, and the core with the fire retardant material therein is configured to facilitate compression of the core when installed between the first substrate and the second substrate by repeatedly expanding and contracting to accommodate movement of the first substrate and the second substrate; and the core with the fire retardant material included therein is configured to pass the testing mandated by UL 2079. Movement of one or both of the first substrate and the second substrate causes a response in the central portion to maintain the seal.

The invention provides a generally horizontal roof deck having a corner and two parapet walls meeting at the corner. A roofing membrane has a major portion adhered to the roof deck and a side portion adhered to the first parapet wall and an end portion adhered to the second parapet wall. A bead of caulk is located between the side portion and the end portion and a respective parapet wall. Termination bars are affixed to the each of the parapet walls by axially driven pins that capture the termination bars on top of the respective side or end portions along their upper edges. Also disclosed is a method for constructing a roof deck using termination bars and axially driven pins that do not require predrilled holes.
