ABSTRACT:
A method of making algae-resistant shingles in which the algae-inhibiting material, usually a copper compound, is applied only to larger granules, instead of being applied to a full size range of granules. Use of the larger granules only, as algae-resistant granules, significantly increases the percentage of surface area of algae-resistant granules for releasing algae-inhibiting material and also reduces the material consumption of the algae-inhibiting material during production of the algae-resistant granules, thus substantially reducing cost.
