A roofing antigrowth strip adapted to be installed on either a shingled or tiled roof, said strip constructed of a metal which releases ions into rainwater runoff which inhibit growths such as moss, mildew, lichens and the like, 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 which tabs may be bent out of a general plane defined by said strip so as to be engageable with an undersurface of a roofing be tile installed over said tabs so that said upper nailing flange section may be held in position beneath said roofing tile by engagement of one or more of said tabs with said undersurface of said tile to hold said strip in position on said roof;
said upper nailing flange section also formed with a plurality of lengthwise spaced apart sets of nailing holes formed spaced apart and arranged along the length of said upper nailing flange section and below said tabs, said nailing holes located to insure coverage by a shingle of the head of a nail received in at least one of said holes with a roofing shingle by selecting one of said holes in a set which is covered by a shingle to drive a nail through to secure said strip to a roof deck. |
