A drip edge having a flange configured to rest against a roof surface following installation on a perimeter of the roof surface and a flap hingedly extending from a terminal edge of the flange configured to be positioned a predefined distance towards the center of the roof surface, as measured from an edge of the roof surface on which the flange is configured to be mounted, following installation of the flange on the roof surface, wherein the flap and flange, in combination, form a cavity configured to retain a shingle therein, thereby improving the strength with which the starter shingle is secured to the roof surface against wind uplift while improving its resilience to moisture intrusion and easing installation while also rendering shingle alignment more consistent.

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.

A system for protecting walls/roofs from water uses a detachable flashing channel and a step flashing unit. The detachable flashing unit is a J shape structure which facilitates the protection of walls from rain water and the step flashing unit is a L shape structure also facilitating the protection of roofs from rain water.

A house sealing method is herein provided. The method involves using a tacky on both sides detail membrane having a reinforced inner core to seal various areas of a building envelope.

A finishing shingle includes a sheet having a front surface and a rear surface. The front surface is configured to resemble the shingle installed on a roof with which the finishing shingle will be used. The sheet further includes a central, frangible seam longitudinally extending from one side edge to an opposing side edge that allows a worker to easily separate the sheet into two equal finishing shingles that are substantially half the size of the roof shingle. Nail targets positioned on the top surface provide a template for a worker to nail the finishing shingle to the underlying flashing. Circular sealant patches on the rear surface are aligned with the nail targets to form a watertight seal around the nail and flashing.

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.

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.
