Unfortunately, algae growth is unavoidable, especially if your home is in a shady area surrounded by trees and vegetation. Algae discolor your shingles, eventually causing them to disintegrate and detach. GAF’s new StainGuard Plus™ shingles offer a 25-year limited warranty against blue-green algae discoloration. Its proprietary time-release copper ion technology releases ten times as much stain-fighting copper as its traditional copper-coated mineral granules to better resist algae growth.

This advanced technology provides the holding power to protect your home from whatever Mother Nature throws its way—and it comes with GAF Windproven™ Infinite Wind Speed Protection limited warranty.
