Blue-green algae is on more than 80% of the U.S., including the Columbus, Ohio area. You will see dark black stains on roofs wherever it grows, making millions of perfectly good roofs look old before their time.

It's algae resistance is so powerful, GAF offers a 25-year limited warranty against blue-green algae discoloration

Many traditional algae-resistant shingles use a granule technology developed more than a quarter century ago. The granules contain a layer of algae-fighting copper.

As a roof ages, those older granules release less and less copper, which reduces the shingle’s algae resistance over the life of your roof.

StainGuard Plus™ Time-Release technology from GAF releases algae-fighting copper more efficiently for long-lasting algae-fighting power. It’s algae resistance is so powerful, GAF offers a 25-year limited warranty against blue-green algae discoloration.

StainGuard Plus™ technology uses specially engineered capsules. The capsules are infused throughout with thousands of copper microsites. The copper remains within reach, ready to be activated, fighting blue-green algae stains.
