Dark stains; algae-inhibiting granules; asphalt shingle test panels; ARMA; warranty terms

In 2009, I wrote about the development of algae-inhibiting surfacing granules for asphalt shingles and the then-available algae-resistant asphalt shingle products and associated warranty terms (see “The fight against algae,” April 2009 issue). But the industry has evolved since then, and there have been some changes in the current algae-resistant shingle market and associated product warranty terms.
