A combination drip edge, rake flashing, gutter with nail flange that is useful for water harvesting and securing of shingles in adverse weather conditions.

A ventilation screed with an upper attachment flange having a top portion and a bottom portion and at least one opening in the top portion; a drip edge protruding from the bottom portion and a return leg that protrudes back from the drip edge and extends beyond the bottom portion; a drainage cavity protrusion protruding from the bottom portion above the drip edge, wherein the drainage cavity protrusion has an L-shaped drainage trough portion having at least one drainage opening in a bottom portion and a substantially vertical portion with a top end and a bottom end in communication with the bottom portion, an upper ground portion in communication with the top end of the substantially vertical portion of the L-shaped drainage trough portion extending outward from the substantially vertical portion and a drainage cavity shroud extending substantially downward from the upper ground portion.

A recording head has a near-field transducer proximate a media-facing surface of the recording head. The near-field transducer extends a first distance away from the media-facing surface. A waveguide overlaps and delivers light to the near-field transducer. Two subwavelength focusing mirrors are at an end of the waveguide proximate the media-facing surface and extend a second distance away from the media-facing surface that is less than the first distance. The subwavelength mirrors are on opposite crosstrack sides of the near-field transducer and separated from each other by a crosstrack gap. The subwavelength focusing mirrors each include a first material at the media-facing surface; and a second material facing away from the media facing surface and in contact with the first material. The second material includes a plasmonic material, and the first material is more mechanically robust than the second material.

A shingle assembly for installation on a roof structure is provided. The shingle assembly can include an insulative substrate, a surface sheet coupled to and extending across a substantial portion of the insulative substrate, and a hook-and-loop fastening system comprising a hook portion and a loop portion. The hook portion or the loop portion can be coupled to and extend along the insulative substrate adjacent the surface sheet. The other of the hook portion or the loop portion can be coupled to and extend along the surface sheet. The hook portion can be configured to mate with a loop portion of a first adjoining shingle assembly and the loop portion can be configured to mate with a hook portion of a second adjoining shingle assembly.

Hereby is disclosed a second layer roofing drip edge with a protruding edge. The drip edge covers an existing drip edge and shingles at the eave and rake prior to the installation of the next roofing system. The protruding edge may be notched on one section and not the other section as they abut. The protruding edge bottom fold or bottom face of the drip edge may be fabricated with a groove or projection preventing capillary action of water across the plane and dropping behind the gutter.

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.

An improved gutter flashing is disclosed. The gutter flashing can be installed on a preexisting fascia board of a building, and is compatible with the installation gutter hangers, leaf protection devices, and pre-existing drip edges or gutter flashing. The gutter flashing can be installed without placing additional holes for screws, nails or other securing devices other than the attaching devices that attach the gutter to the fascia board. The gutter flashing comprises a lower spacer portion, a substantially vertical arm with a substantially u-shaped spacing portion to receive the lower angled leg of the preexisting drip edge. Diverter arm rests on top of the roof portion of the preexisting drip edge and extends into approximately the midline of the gutter to divert water away from the structure and into the gutter.
