Blue-green algae, also known as Gloeocapsa Magma and cyanobacteria, is a type of microscopic bacteria that thrives in moist environments. It usually appears as black or dark stains on asphalt shingles, making roofs appear older.
But if you have plans of selling your home in the near future, experts in roofing repairs would likely suggest fixing your roof’s algae problem as this can affect the appearance and resale value of your home.
If you’re thinking of replacing your roof, algae-resistant shingles — such as those designed with GAF StainGuard Plus™ Time-Release Technology and Owens Corning® StreakGuard™ Algae Resistance Protection — are worth considering.
With Owens Corning StreakGuard Algae Resistance Protection, the shingle granules are lined with copper to make the shingles resistant to algae growth. The shingles are available in various colors to match different aesthetics, and they are developed to meet the specific needs of regional climates.
GAF StainGuard Plus shingles also have copper-containing granules. However, copper particles are discharged through time-release capsules, which facilitate a gradual and steady release of particles over time. Because of this, the roof can have longer-lasting protection against algae. In older technology, most of the copper particles are usually released at the beginning, so less copper is released after some years, making the shingles less effective after a certain period.
Copper has been a reliable and durable material. That’s why it comes highly recommended for seamless gutters and other types of structures.
Furthermore, copper is also effective against algae growth due to its antibacterial properties. If you live in a humid region, it would be a good idea to consider installing shingles with copper-consisting granules so as to keep your roof protected from ugly dark stains caused by algae.
