Abstract

A shingle insert strip and method for eliminating and preventing growths on a shingled roof in which porous copper strips are installed with upper edges beneath the bottom edges course of shingles with the remaining portions exposed. A confined space is defined beneath a lengthwise hump in the exposed portions which is filled with a material, preferably in granular form which releases a substance toxic to the growths when rainwater runoff passes into the confined space and material and thereafter flows out.

Claims

1. A shingle insert strip for reducing the growths of algae, moss, lichens, or fungus on roofs comprising:

an elongated generally planar strip of copper having a lengthwise hump formed therein defining an underspace, said underspace filled with a material which kills releases a substance into rain runoff which is toxic to such growths;

said copper strip having openings allowing penetration of rainwater runoff from above into said underspace and to thereafter flow out onto a roof surface below said strip;

said copper strip having one upper edge adapted to be inserted beneath shingle courses above said strip to position remaining portions thereof exposed to receive rainwater runoff.

2. The shingle insert strip according to claim 1 wherein said copper strip is comprised of one or more layers of copper mesh.

3. The shingle insert strip according to claim 1 wherein said copper strip is a slotted sheet.

4. The shingle insert according to claim 1 wherein copper cover strip is attached to an undersurface of said first mentioned copper cover strip to cover said underspace and confine said material therein.

5. The shingle insert according to claim 4 wherein said cover strip is comprised of copper mesh.

6. The shingle insert according to claim 1 wherein said material is in granular form.

7. The shingle insert according to claim 6 wherein said material is a copper complex.

8. The shingle insert according to claim 1 wherein said copper strip has a scalloped lower edge exposed when installed on a shingled roof.

9. The shingle insert according to claim 2 wherein said copper strip is formed with a double layer of copper mesh.

10. A method of eliminating growths on shingled roofs comprising:

installing a series of copper strips each having an upper edge disposed beneath the lower edge of shingles in a course of shingles so as to leave exposed a lengthwise porous hump formed in said copper strips;

loading a material into a space defined beneath said hump which releases a substance toxic to said growths when rainwater runoff flow passes into and out of said humps after passing over or through said material; and

covering said space from below to confine said material in said space.
