ROOF SHINGLE INSERT FOR ELIMINATING AND PREVENTING ALGAE, MOSS, OR LICHEN GROWTH ON A ROOF

BACKGROUND

Most conventional roofs suffer from the growth of algae, moss, lichens, and/or fungus. Such growths can be unsightly and also damage asphalt shingles by loosening the granules embedded therein which loss shortens the service life of a shingled roof.

Also, water is retained by such growths delaying the complete drying out of the roof after a rain and such. This prolonged contact with moisture also contributes to the shortening of the service life of a shingled roof.

To address this issue, copper and/or zinc strips have been installed on roofs to deter the growth of algae, moss, lichens, and/or fungus. These strips are often only effective for a few courses of shingles such that multiple rows of strips are required.

In addition, these strips act slowly and cannot quickly eliminate an existing buildup of such growths if the strips are installed much later after the roof itself has been installed.

An example of a conventional copper strip for a roof is disclosed in U.S. Pat. No. 9,103,124. The entire content of U.S. Pat. No. 9,103,124 is hereby incorporated by reference.

As disclosed in U.S. Pat. No. 9,103,124 and illustrated in FIG. 1, a copper sheet strip (roof shingle insert) 28 is installed on a roof. The copper sheet strip 28 has a series of elongated indentations 29 formed thereby to allow rainwater to penetrate through the copper sheet strip 28 and into a lengthwise arched hump 18 and into space A which is packed with algaecide granules.

A copper mesh bottom strip 24 is attached to close off the space A and hold the granules therein. The strip 24 has a protruding edge for nailing. The ends 30 of the strip 24 are wrapped over the ends (only one end shown) to close off the ends of the space A and prevent escape of the algaecide granules.

The sheet 28 is also formed with a series of scallops 29 along its bottom edge to provide a large area exposed to moisture run off while maintaining a good appearance.

U.S. Pat. Nos. 7,788,870; 9,499,988; and 10,202,771 disclose other examples of a conventional copper strip for a roof. The entire contents of U.S. Pat. Nos. 7,788,870; 9,499,988; and 10,202,771 are hereby incorporated by reference.

Although the various conventional copper strips for a roof allow for the water run-off to be exposed to the copper to provide the deterrent effect, the amount of exposure time is not optimized to provide a more effective deterrent, thereby increasing the effectiveness of the exposed run-off water to eliminate and/or prevent the growth of algae, moss, lichens, and/or fungus on a roof.

Therefore, it is desirable to provide a copper and/or zinc strip which increases the amount of exposure time of the run-off water with the strip.

It is also desirable to provide a copper and/or zinc strip which increases the amount of exposure time of the run-off water with the strip to effectively eliminate and/or prevent the growth of algae, moss, lichens, and/or fungus on a roof.

DETAILED DESCRIPTION OF THE DRAWINGS

For a general understanding, reference is made to the drawings. In the drawings, like references have been used throughout to designate identical or equivalent elements. It is also noted that the drawings may not have been drawn to scale and that certain regions may have been purposely drawn disproportionately so that the features and concepts may be properly illustrated.

FIG. 2 illustrates a perspective view of the top, front and right sides of a roof shingle insert 100. As illustrated in FIG. 2, the roof shingle insert 100 includes a top side 110, an upper edge 140, and a lower edge 150. In a preferred embodiment, the roof shingle insert 100 is constructed of a copper sheet. The roof shingle insert 100 may also be constructed of zinc or a copper zinc alloy.

In other words, the roof shingle insert 100 is to be constructed of a metal or metal alloy that deters the growth of algae, moss, lichens, and/or fungus.

The roof shingle insert 100 includes, on the top side 110, projections 120 that create holes or openings 130 in the roof shingle insert 100 to allow water to flow from the top side 110 of the roof shingle insert 100 to a roof shingle (not shown) underlying the roof shingle insert 100. The projections 120 are formed across the openings 130.

The projections 120 are formed in a lower portion 155 of the roof shingle insert 100, which is associated with lower edge 150. An upper portion 145 of the roof shingle insert 100, which is associated with upper edge 140 is free of the projections 120.

The upper edge 140 comes in contact with the roof shingle (not shown) underlying the roof shingle insert 100 and a roof shingle (not shown) overlying the upper portion 145 of the roof shingle insert 100.

The upper edge 140 and the lower edge 150 are coplanar with the top side 110.

At the lower edge 150 of the roof shingle insert 100, the lower edge 150 of the roof shingle insert 100 includes a spacing member 160 to raise the roof shingle insert 100 above the roof shingle (not shown) underlying the roof shingle insert 100 so as to create a gap between the roof shingle insert 100 and the roof shingle (not shown) underlying the roof shingle insert 100. The spacing member 160 raises the roof shingle insert 100 above the roof shingle (not shown) underlying the roof shingle insert 100 so that the lower edge 150 does not come in contact with the roof shingle (not shown) underlying the roof shingle insert 100.

The spacing member 160 may be integral with the lower edge 150.

Moreover, the spacing member 160 may be formed by folding back a portion of the roof shingle insert 100 upon itself such that the lower edge 150 is V-shaped or U-shaped. The V-shaped or U-shaped lower edge 150 raises the roof shingle insert 100 above the roof shingle (not shown) underlying the roof shingle insert 100 so as to create a gap between the roof shingle insert 100 and the roof shingle (not shown) underlying the roof shingle insert 100.

This gap allows for the collection of water so as to increase the exposure of the water to the roof shingle insert 100, which aids in deterring the growth of algae, moss, lichens, and/or fungus. The gap, formed by the V-shaped or U-shaped lower edge, also slows the rate of flow of the water to increase the exposure of the water to the roof shingle insert 100 so as to deter the growth of algae, moss, lichens, and/or fungus.
