What is the Black Stuff on Your Home's Roof? | Black Algae

Jan 9, 2019
Roof Problems

Your roof is an integral part of your home's protection, shielding you and your belongings from the elements. However, you may have noticed black stains or streaks on your roof, commonly known as "black algae." Understanding what this black stuff is and how to handle it is important for maintaining the appearance and longevity of your roof.

The Nature of Black Algae

Black algae, scientifically known as Gloeocapsa magma, is a type of bacteria that commonly thrives on roofs. It appears as dark stains or streaks, most notably on asphalt shingle roofs. Black algae gets its name from its appearance, but it's important to note that it is not an actual plant. Instead, it is a cyanobacteria that feeds off moisture and organic matter found on your roof.

Black algae spores typically find their way onto roofs through wind or wildlife, but they can also spread from neighboring roofs. Once they settle, the algae multiply and form dark clusters. The black coloration helps them absorb more sunlight, enabling them to thrive and grow.

The Impact of Black Algae on Your Roof

While black algae may seem harmless and only a cosmetic issue at first, it can have significant consequences for your roof. Some of the effects of black algae include:

  • Reduced Curb Appeal: The black stains and streaks caused by black algae can be unsightly and may diminish the overall aesthetics of your home. This can be a concern, especially if you're planning to sell your property in the future.
  • Algae Growth Spreading to Other Areas: If left untreated, black algae can spread to other sections of your roof, resulting in a larger infestation. This can lead to even more extensive and costly damage.
  • Accelerated Roof Deterioration: Over time, black algae can degrade the protective granules on your asphalt shingles, reducing their effectiveness and lifespan. This deterioration can lead to premature roof aging, requiring repairs or even a full replacement sooner than expected.
  • Potential Functional Issues: Thick clusters of black algae can disrupt the natural water flow on your roof, preventing proper drainage. This can result in water pooling, leaks, and ultimately, water damage to your home's interior.

Removing and Preventing Black Algae

If you've noticed black algae on your roof, it's essential to take action promptly to prevent further damage. Here are some steps you can take to remove and prevent black algae:

1. Cleaning with the Right Techniques:

When removing black algae from your roof, it's crucial to use the correct cleaning methods to avoid causing additional damage. Pressure washing is not recommended, as it may dislodge shingles or drive water beneath them, leading to water intrusion. Instead, consider using a soft washing technique, which involves low-pressure water and environmentally friendly cleaning solutions.

2. Hiring Professional Roof Cleaning Services:

While DIY methods can be effective, hiring professional roof cleaning services ensures thorough cleaning and prevents accidental damage. St Louis Premium Roofing offers expert roof cleaning services, including the safe and efficient removal of black algae. Our experienced team utilizes industry-approved techniques to eliminate black algae while preserving the integrity of your roof.

3. Installing Algae-Resistant Roofing:

If you live in an area prone to black algae growth or want to prevent future infestations, consider installing algae-resistant roofing. Many manufacturers offer shingles that incorporate copper or zinc granules, which hinder algae growth. These roofing materials can help prolong the appearance and lifespan of your roof.

4. Regular Roof Maintenance:

Maintaining your roof is key to preventing the recurrence of black algae. Regular roof inspections, gutter cleaning, and removing overhanging tree branches can minimize the factors that contribute to black algae growth. Professional roof maintenance services, like those provided by St Louis Premium Roofing, can help ensure your roof remains in optimal condition.
