A roof shingle insert includes a top side; a bottom side; an upper edge; a lower edge; and openings. The lower edge includes an integral spacing member. The integral spacing member is configured to raise the lower edge above a roof shingle and is configured to form a gap between the bottom side of the roof shingle insert and a roof shingle.

The present disclosure relates generally to a roofing granule mixture, the mixture comprising a first class of roofing granules consisting of non-algae-resistant roofing granules, and a second class of roofing granules consisting of algae-resistant roofing granules having a d50 particle size of at most 0.9 mm.

A coating composition is provided for inhibiting growth of fungus and/or algae on a surface. The coating composition includes a dry film preservative and an antibacterial dry-film preservative comprising an immobilized isothiazolin-3-one derivative/zinc oxide complex. The amount of the antibacterial preservative comprising immobilized 1,2-isothiazolin-3-one derivative/zinc oxide complex and the dry film preservative contained in the coating composition is sufficient to inhibit or prevent the defacement of a surface exposed to the environment, when such defacement is due to growth of fungi or algae, or a combination of fungi and algae on a surface coated with said surface coating composition.

The method includes dispersing copper or other material ions through the water receiving area of a gutter guard for the prevention of moss or mold growth. The method includes the utilization of thread(s) sewn into or embroidered onto or otherwised affixed to or immediately preceding the water receiving areas of a gutter guard, such thread(s) being comprised of moss killing materials. The thread(s) comprise only a portion of the water receiving area, so if corrosive elements form and wash over the water receiving area, they will be in sufficient amounts to kill moss but not in so great an amount as to clog any water receiving apertures. The method includes the utilization of staples or other objects comprised of copper or other moss killing materials fastened to or adhered or welded to the body or water receiving areas of a gutter guard or areas immediately preceding such.

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 particulate composition suitable for protection against lightning is disclosed. The particulate composition comprises of a particulate matter comprising a mineral compound, preferably black tourmaline, capable of emitting negatively charged ions continuously, a grinding auxiliary agent, and a liquid medium. The particulate composition is embedded in a substrate, coating or mixed into the granules of composite roofing to protect people, objects and structures from lightning by developing a negatively charged cloaking shield to prevent the attraction of negatively charged lightning from striking. The composition infused or applied on a subject continuously emits negative ions sufficiently producing a protective electromagnetic cloaking shield restricting the wicking action of positive ions up from ground surface and thereby restricting the formation of positive streamers that reach upwards towards the stepped leaders of lightning.

Provided are roofing granules, such as algaecidal roofing granules, methods for making them and their use in roofing products. In one aspect, the disclosure provides an algaecidal roofing granule that comprises an ion-exchanged zeolite disposed within the binder, wherein the ion-exchanged zeolite comprises algaecidal ions.

Granules include a hydrophobic surface treatment. The hydrophobic surface treatment may include a hydrocarbon oil and a silicon-containing polymer, in which the hydrocarbon oil is present in an amount of at least 0.025 percent by weight, and the silicon-containing polymer is present in an amount of greater than 0.05 percent by weight of the roofing granules. The hydrophobic surface treatment may include silicon-containing polymer present in an amount of greater than 0.05, greater than 0.25 percent, or greater than 0.5 percent by weight of the roofing granules. Use of the granules as roofing granules is also disclosed. A construction article includes a substrate, an organic coating, and the roofing granules at least partially embedded in the organic coating. Methods of making the granules and the construction article are also disclosed.
