Asphalt Roofing Fine Print on Algae Discoloration
This StainGuard® Limited Warranty lasts for 10 years on all StainGuard® labeled shingles. GAF-Elk warrants to you that blue-green algae (also known as cyanobacteria)will not cause a pronounced discoloration of your StainGuard® labeled shingles. During the first year, if your StainGuard® labeled shingles do exhibit a pronounced discoloration caused by blue-green algae, GAF-Elk’s contribution will be either the reasonable cost of commercially cleaning your shingles or replacing discolored shingles. During the remainder of the algae discoloration coverage period, GAF-Elk’s contribution to you will be adjusted to reflect the use you have received from your shingles, based on the number of months that have elapsed since your shingles were installed.
