Understanding Roof Streaks and How to Fix Them

If you’ve noticed black streaks or dark patches on your asphalt shingle roof, particularly common in southern regions, you may be wondering what causes them. These unsightly marks are not just dirt or grime; they’re actually the result of living spores from a type of cyanobacterium algae that feeds on the limestone in your roof shingles. Over time, this algae can damage the integrity of your roof and significantly reduce its lifespan.

The culprit behind these black streaks is Gloeocapsa magma. This algae thrives on the mineral content in asphalt shingles, particularly the limestone that’s commonly used in roofing materials. The bacteria settle on the roof, often more densely on the north-facing sides where moisture tends to linger. The dark stains you see are actually the bacteria colonies themselves, which spread over the surface of your shingles.

The Damage and Solution

While the black stains may seem merely cosmetic, they can have long-term consequences. Over time, these spores degrade the shingles, leading to premature wear and tear. The accumulation of algae can prevent your roof from reflecting sunlight properly, potentially increasing energy costs by absorbing more heat. Left untreated, this can reduce the life expectancy of your roof and leave you with costly repair bills or even a complete roof replacement, which can run into the tens of thousands of dollars.

Fortunately, a new patented product has been developed that offers an effective solution to this problem. Unlike traditional roof cleaning products that typically contain harsh chemicals like bleach, zinc, or copper, this new treatment is environmentally friendly and safe for both your roof and the surrounding area. It is inexpensive, easy to apply, and can be easily applied used by technicians, often without requiring them to climb onto your roof.

How CEERTAIN Works

The treatment, named CEERTAIN™ (Cost Effective, Environmental Roof Treatment Application Incredibly Noticeable), works by killing the algae spores and allowing the natural process of rainwater to scrub them away. While it’s not an immediate fix, the results are long-lasting and will gradually restore the appearance of your roof, extending the life of your shingles. CEERTAIN™ rejuvenates your roof by removing the algae buildup, which helps to prevent further damage.

What makes CEERTAIN™ stand out from other products is its simplicity and environmental safety. It’s easy to apply, cost-effective, and provides a lasting solution that can help avoid the need for expensive roof replacements. For a one-time application cost of just a few hundred dollars, this product offers a fraction of the cost compared to roof replacement.

With many homes in the southern U.S. suffering from algae streaks on their roofs, there’s a vast market for this roof remediation treatment. Homeowners and property managers across the region are starting to realize that treating their roofs with CEERTAIN™ is an affordable and effective alternative to costly roof replacements.
