A multi-layered integrated roofing plank or panel with a base layer comprising engineered or manufactured wood, a water resistant barrier layer covering at least the outer face of the base layer and at least one of the edges of the base layer, and a driplap edge along the bottom edge of the base layer. A texturizing material also may be affixed to, or integrated with, the water resistant barrier layer.

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 profile for terraces and balconies includes a substantially flat wing for anchoring the profile to the floor of the terraces, a front portion for protection of the external edge of the flooring which protrudes outward with respect thereto, and a first drip lip constituted by a contoured element which extends downward. The first drip lip has, at the lower end, at least one first protrusion and at least one second protrusion, lower than the first, both protruding downward and outward with respect to the front portion. The profile also includes a second drip lip, which is substantially parallel to the first drip lip, extends downward from the wing and includes a third protrusion which protrudes downward and toward the first drip lip.

An interlocking panel system for covering a base surface with interlocking panels to prevent water ingress. A first panel is secured to the base surface. A second panel interlocks with the first panel via a hook portion on the second panel entering a receptacle of the first panel. The hook portion expands after entering a retaining portion of the receptacle, thereby preventing the hook portion of the second panel from being withdrawn from the first panel.

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.

Some embodiments of the present disclosure relate to a roofing system. In some embodiments, the roofing system comprises at least one steep slope roof substrate having a first region. In some embodiments, the first region comprises a plurality of shingles. In some embodiments, each of the plurality of shingles comprises at least one antimicrobial agent. In some embodiments, the at least one steep slope roof substrate also comprises a second region. In some embodiments, the second region comprises an antimicrobial scavenger layer that is configured to receive runoff from the first region of the steep slope roof substrate. In some embodiments, the runoff comprises an initial concentration of at least one antimicrobial agent and water. In some embodiments, the antimicrobial scavenger layer is configured to capture the at least one antimicrobial agent so as to reduce the initial concentration of the at least one antimicrobial agent in the runoff.

The roof ice and water shield includes a bottom layer of asphalt material configured to lay against a roof surface following installation on a perimeter of the roof surface, the bottom layer having a terminal lower section configured to be adjacent a roof edge at the perimeter of the roof surface following installation, and the bottom layer having a terminal upper section opposite the terminal lower section. A top layer of asphalt material extends from the terminal lower section of the bottom layer in a direction towards the terminal upper section of the bottom layer, an upper section of the top layer is configured to create a watertight seal with the terminal upper section of the bottom layer, and a lower section of the top layer defines a flap configured to overlap the terminal lower section of the bottom layer during installation. A sealable drip edge pocket is between the flap and the bottom layer and configured to sealably envelop a top portion of a drip edge following installation.

A recording head has a near-field transducer that extends a first distance away from a media-facing surface. Two subwavelength focusing mirrors are at an end of a 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 plasmonic material that covers an edge of the subwavelength focusing mirror that faces the near-field transducer. The first material is more mechanically robust than the plasmonic material.

A ventilation screed comprising: an attachment flange having a top portion and a bottom portion; a drip edge protruding from the attachment flange and a return leg that protrudes back from the drip edge, wherein the drip edge is angled downward in a first direction and the return leg is angled downward in a second direction; a drainage cavity protrusion protruding from the attachment flange 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.
