Abstract
A shingle insert and method for eliminating and preventing growths on a shingled roof in which copper strips forming the inserts are installed with an upper edge disposed beneath a course of shingles with the remaining portions of the insert exposed. The insert strips have a confined space defined beneath a stiffening lengthwise extending arched hump formed in the exposed copper strip portions which has an array of elongated indentations formed therein with slits therein to allow slow drainage of water impounded by the arched hump through the inserts may contain a growth toxic material, in solid or granular form which releases a substance toxic to the growths when rainwater runoff passes into the confined space and over the material and thereafter flows out down the roof.
