A Look at GAF’s StainGuard Plus™ Technology

Scientists refer to them as cyanobacteria; roofing experts call them blue-green algae. But to average homeowners, they’re nothing but an eyesore.

Microscopic yet noticeable, their dark, UV-resistant coating collectively leaves black or brown streaks. They may not pose any structural threat to a roof, but they never fail to make stunning shingles unsightly. Like mold, blue-green algae are ubiquitous and thrive in moisture. If your neighbor’s roof has them, yours has most likely been exposed too.

Fortunately, blue-green algae are preventable. Any GAF Master Elite™ residential roofing contractor, like Dior Construction, would say that GAF’s StainGuard® protection has been the ultimate solution to combat algae discoloration–despite its limitations. But now, GAF is introducing the next leap forward to algae-growth prevention: the StainGuard Plus™ time-release technology.

Efficient Copper Delivery

Unlike StainGuard protection, StainGuard Plus technology uses specially engineered capsules containing thousands of copper microsites. It lends superior algae resistance to shingles because it distributes copper with efficiency. As a result, this anti-algae breakthrough allows shingle granules to continue releasing copper when activated by moisture even when they get old.

Exclusive Technology

StainGuard Plus technology is a patent-pending innovation by GAF. This means you can only capitalize on this anti-algae wonder with GAF products, like the Timberline Ultra HD® Shingles. StainGuard Plus technology is one more reason to take advantage of the residential roofing services of a Master Elite roofer.

Long-Lasting Stain Protection

GAF shingles that bear the StainGuard Plus technology label come with a 25-year limited warranty against algae discoloration and a non-prorated period of 10 years. In other words, your roof is guaranteed not to have pronounced dark stains for a long time.

In case your StainGuard–protected shingles exhibit pronounced blue-green algae discoloration during the first 10 years, GAF vows to fix the problem. Its contribution will either be the cost of cleaning them or new asphalt shingles installation to replace the affected components.
