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.

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. 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 liner that covers an edge of the mirror.

A roof drip edge including a roof leg and a drip leg joined to a down leg adapted to protect the intersection of a roof and fascia of a building. Some embodiments include a back drip leg adjacent to the drip leg. Some embodiments include tabs positioned on the roof leg for protection from water infiltration under roof shingles.

A drip guard made of one-piece construction having an elongated member having a top section, a first angled section, a second angled section, a bottom section, and a downward section that are formed by bending the elongated member at a plurality of transition points. At least a portion of the first and second angled sections engage one another and/or at least a portion of the top section and bottom section engage one another.

A roof ice melt system and method of making and use to reduce or eliminate water from puddling or not running down the ice melt system and off of the roof. One embodiment of the roof for the roof ice melt system can has a slope of between approximately 0.5/12 and approximately 2.5/12. The roof ice melt system has a heating element and heatable cover panel having a a primary heating element cover section, an upper roof contacting section, and an intermediate cover section extending between the primary heating element cover section and the upper roof contacting section. The intermediate cover section is sized so that it extends downwardly along the roof, rather than horizontally or higher, from the upper roof contacting section toward the primary heating element cover section.

An ice backing flashing layer for a roof including an upper portion attachable to an upper surface of the roof, a lower portion attachable to a fascia portion of the roof, and a bend between the upper and lower portions attachable over an edge of the roof. A roofing system including a first underlayment layer and the ice backing flashing layer adjacent to and above the first underlayment layer. The roof system optionally including at least one of a second underlayment layer adjacent to and above the upper portion of the ice backing flashing layer, a drip edge layer adjacent to and above the second underlayment layer, or a third underlayment layer adjacent to and above the drip edge.

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.

Systems, components, apparatuses, kits and methodologies of the present invention are directed to techniques that ensure that all deck-to-wall, roof-to-wall and other constructions properly protect the home from the environment, particularly along the wetter coastal regions by forming a layered, waterproof seal of metal, plastic and bitumen. A modularized system of components, that overlap each other either over and or under to create a system that meets the design criteria of critical flashing components, each with waterproofing capability either built-in or applied onsite in use, are employed to cover critical building areas prone to water infiltration and damage.
