Abstract

Antigrowth roofing strips made of a metal which release antigrowth ions into rainwater runoff from the roof which are formed with nailing hole sets insuring covering of nail heads with shingles. The strips also are formed with variously bent up or down tabs enabling securement to roofing tiles.

Claims

1. A roofing antigrowth strip adapted to be installed on either a shingled or tiled roof, said strip constructed of an elongated solid strip of metal which releases ions into rainwater runoff of a type which inhibit growths of moss, mildew, and lichens, said strip metal having areas formed with indentations therein capturing rainwater with openings in said indentations allowing rainwater runoff to pass through said strip and contact an undersurface of a flat lower section thereof lying flat on a roof to increase the release of ions into said runoff, said strip including an upper nailing flange section adapted to be installed under roof covering pieces with remaining parts of said strip extending over roofing pieces and exposed to rainwater, said strip having a series of tabs formed in said upper nailing flange section of said strip by spaced apart pairs of slots cut into an upper edge of said upper nailing flange section along the length of the strip, which tabs are able to be bent up and back out so as to be engageable with roofing tiles installed over said tabs so that said upper nailing flange section is held in position by engagement on said roof;

said upper nailing flange section also formed with a plurality of lengthwise spaced apart sets of preformed nailing holes each adjacent to the other in each set formed spaced apart, said sets arranged spaced apart along the length of said upper nailing flange section and below said tabs, said sets of nailing holes located to ensure that a head of a nail inserted in at least one hole of each set and driven into underlying roof deck will be covered by the roofing tiles and not exposed by any slots in said roofing tiles installed on the roof, with a lower edge of the roofing tiles overlying said upper nailing flange section of said strip.

2. A method of securing antigrowth solid sheet metal roofing strips to a tile roof installed on said roof, over an upper section of said metal strips leaving a lower main section of said strips exposed, including forming bendable tabs along said upper section of said strips by cutting a series of spaced apart pairs of slots into an edge extending along and above said upper section of said strips and bending said tabs up to be above a plane generally defined by each strip so as to be ensured of engaging an undersurface of a tile piece installed over said strip upper section so as to retain said strip to said tile roof by said tile piece frictionally engaged therewith;

and,

forming sets of adjacent holes into said upper section of said strip, said sets spaced apart lengthwise along the length of said strip and located below said tabs so as to insure that one holes in each set will be covered by the tile piece so as to avoid exposing a head of a fastener installed in a hole of any of said set of holes in said strip.
