Video: How GAF StainGuard Plus™ Prevents Roof Algae

Blue-green algae can be a major eyesore. Microscopic yet noticeable, their dark, ultraviolet-resistant coating leaves black or brown streaks. They may not pose any structural threat to a roof, but they make stunning shingles look ugly. Like mold, blue-green algae are ubiquitous and thrive in moisture.

In this video, we describe how traditional algae-resistant shingles fight this menace. They use granules of algae-fighting copper, which gets released onto the wet roof. But as the roof ages, older granules release less copper. This reduces the shingle’s algae resistance. This is why we install GAF StainGuard Plus™.

GAF StainGuard Plus™

GAF StainGuard Plus Time-Release technology releases algae-fighting copper better over time. Its engineered capsules are well infused throughout with thousands of copper microsites. These capsules release ten times more copper than the old technology. Over time, the capsules release only the right amount of copper to help keep the roof stain-free. That’s why it’s called time-release technology; its algae resistance is so powerful that it comes with a 25-year limited warranty.

Long-Lasting Stain Protection

StainGuard Plus 25-year limited warranty also includes a non-prorated period of 10 years. That’s a long period of time to enjoy a stain-free roof. Should any discoloration occur within the first 10 years, GAF will fix the problem. The company will bear the cost of cleaning the shingles or replacing the affected components.

Timberline® Ultra HD® Shingles

StainGuard Plus technology is available with Timberline® Ultra HD® shingles. These shingles are beautiful, durable, long-lasting and 54% thicker than architectural shingles. They feature proprietary color blends and enhanced shadow effects. They look better than ordinary non-architectural shingles because of their ultra-dimensional, wood-shake look. They also feature Dura Grip™ Adhesive that makes them withstand winds of up to 130 miles per hour.
