A method for inhibiting growths on shingled roofs, one or more of the strips installed along shingle courses. The strips are preferably formed of copper and have an upper portion formed with a pattern of through holes along the length of the strip and pattern of dimples extending along a lower portion of the length of the strips to increase the duration and extent of contact of rain or dew with the copper metal to increase the release of cupric ions effective in inhibiting growths on the roof.
