Features and Benefits of GAF’s StainGuard Plus™

Scientifically known as Gloeocapsa magma, you know it as blue-green algae. To the average homeowner, however, they’re nothing but an eyesore on their roofs. Microscopic yet noticeable, these dark, unsightly microbes collectively leave black or brown streaks across the surface. And, while they don’t necessarily pose any structural threat to the roof, their appearance casts a slight pall on your curb appeal. Fortunately, algae stains are preventable. Any GAF Master Elite® residential roofing contractor like A1 Roofing & Construction can help keep them at bay.

Like mold, blue-green algae thrive in moisture and are pervasive. So, if you look at your neighbor’s roof and see blue-green streaks and dark stains, chances are your roof has been exposed, too. Allowed to fester and spread, their dark brownish-black shells, which protect them from sunlight, make perfectly good shingles look old and haggard before their time.

To combat them, we use  GAF’s StainGuard Plus™ protection, an advanced solution that limits the growth and spread of algae discoloration. It’s main features include:

Efficient Copper Delivery

StainGuard Plus technology uses specially engineered capsules that contain thousands of copper microsites. This lends superior algae resistance to roofing shingles because it distributes copper with efficiency when activated by moisture.

Long-Lasting Stain Protection

StainGuard Plus technology is so effective at keeping algae stains at bay that it comes with a 25-year limited warranty against algae discoloration along with a non-prorated period of 10 years. That’s a long period of enjoying a stain-free roof.

On the off-chance that your StainGuard–protected shingles exhibit pronounced blue-green algae discoloration during the first 10 years, GAF will fix the problem, either by shouldering the cost of cleaning them or installing new shingles to replace the affected components.
