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-certified 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. GAF also offers StainGuard Plus™ time-release technology for algae resistance.

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 GAF product feature. 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 GAF-certified roofer.

Long-Lasting Stain Protection

Warranty coverage for algae discoloration depends on the shingles selected. Ask for the current written terms, coverage periods and exclusions for your project.

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.
