Blue-green algae are called cyanobacteria. No matter the name, you know them as eyesores. The algae are microscopic, leaving behind black or brown streaks on your roof. In many cases, they often do not pose any structural threats to a roof, but they make your beautiful shingles take on an unsightly look. Blue-green algae thrive in moisture. If you live in a moist climate, you will have to worry about keeping these cyanobacteria away from your roof. While blue-green algae is a hassle, GAF features innovative technology that can stop them from developing on the roof. Here is a look at GAF’s StainGuard Plus Technology.
GAF’s StainGuard Plus Technology
According to GAF’s own survey of 500 homeowners, 87% said they found protecting their roof from blue-green algae very or extremely important. These products offer the protection that most homeowners want for their roofs. This technology is proprietary to GAF. The company has specially engineered capsules that are infused with copper microsites. Over time, those capsules release algae-fighting copper to prevent them from forming. That means long-lasting protection for your shingles. Along with shingles, GAF’s algae-fighting technology is available on other products, such as ridge caps and starter strips. These products are also covered with a limited warranty.
Is There a Difference Between Blue-Green Algae and Moss?
You might think that blue-green algae and moss are the same, but there are differences in their origins. Plus, there are various ways to remove them. Moss is considered a plant that can do some serious damage to your shingles and roof. On the other hand, blue-green algae are not as destructive but leave behind unsightly surface stains.
All of those algae spores can be transferred to the roof by the wind, especially in warm and moist climate conditions. With that, it creates the ideal environment for blue-green algae development. Once the algae begin to grow, they can spread. Keep in mind that asphalt shingles often contain crushed limestone, a food source for the algae. When the roof does dry, and the algae die, there will be dark discolorations on the surface. GAF understands that blue-green algae are a top concern for homeowners. For that reason, its StainGuard Plus Technology is here to help.
Getting Rid of Algae Stains
When you notice those dark spots or black streaks, it is a cause for concern. In most cases, those discolorations develop in the spring or summer. No, it is not dirt. These cyanobacteria have invaded your roof.
While the first thought might be to clean the roof, you must be careful. Adding cleaning solutions and water to clean the algae stains can make a slippery surface. Power washing is often used to remove stains, but it can wash off the protective granules on the shingles. If you want to clean those shingles, you should call a professional company to handle the job. You might be unable to remove all algae stains with a simple cleaning. Once those blue-green algae spores settle on your roof, you could be stuck with them for a very long time.
How StainGuard Plus Technology Helps
At one time, GAF produced algae-resistant shingles that contained specialized embedded copper granules. They worked well to combat algae but would lose their effectiveness over time. GAF returned to the drawing board and engineered a new type of technology: StainGuard Plus. This innovative, patent-pending breakthrough product is now a game-changer in preventing blue-green algae from developing on your shingles.
Unlike the original StainGuard protection, this Plus technology uses specially-engineered capsules that are infused with thousands of copper microsites. Since the particles are spread throughout the capsule, they are released over a longer period. The evenly distributed copper elements provide enough protection to prevent any algae growth. Your shingle granules will continue to release copper even as they get older. You can only find this advanced technology on GAF’s Timberline Ultra HD shingles with the StainGuard Plus stamp.
As previously mentioned, this technology is exclusive to GAF. If you want the best protection for your roof against the dreaded blue-green algae, you need to purchase GAF products. Along with that, you can ensure complete protection of your roof when you work with a Master Elite roofer who is certified to install and maintain products from the GAF line.
With all GAF products, you are guaranteed long-lasting quality. The StainGuard Plus technology found in this shingle will come with a 25-year limited warranty that protects against algae discoloration. The warranty features a non-prorated period of 10 years. In basic terms, you will not have to worry about dark stains on your roof for a very long time. If your StainGuard Plus shingles do happen to exhibit any blue-green discoloration in those first 10 years, GAF will fix the problem for you. The company will cover the cleaning costs or install new asphalt shingles on the roof.
