Addressing the Growing Concerns of Roof Algae and How to Combat Them

Roofs are more than just a protective barrier for our homes; they are an investment. Over time, various elements can compromise the integrity and appearance of our roofs. One such concern is the growth of algae, lichen, and moss. Dean Roofing Company, a leading roofer in Clearwater FL, sheds light on this issue and offers solutions to homeowners.

Understanding the Algae Menace

Algae, scientifically known as Gloeocapsa Magma, is a resilient organism. It can spread from one roof to another through airborne spores. As communities grow and homes are built closer, the spread of this algae has accelerated. Here’s what you need to know:

  • Adaptability: Algae thrives in various conditions, be it extreme heat, cold, UV rays, heavy rain, or even long dry spells. Its dark color acts as a protective sheath against harmful UV rays.
  • Attachment: Algae secretes a substance that allows it to firmly adhere to shingle surfaces, making it challenging to remove.
  • Water Source: Contrary to popular belief, dew, not rain, is the primary water source for algae. Dew aids in the release of copper in Algae Resistant shingles, which is essential in combating its growth.

The Role of Copper and Zinc

Both copper and zinc play a pivotal role in inhibiting algae growth. However, copper is ten times more effective than zinc. Over time, zinc becomes less effective against algae, whereas copper remains potent. This is why many roofing companies in Clearwater, including Dean Roofing Company, recommend solutions that incorporate copper.

Debunking Myths

  • Myth: Algae is instantly killed by copper. Truth: Algae cells are poisoned over time by copper.
  • Myth: Algae is a type of fungus. Truth: Algae belongs to the Cyanobacteria branch and is not a fungus.
  • Myth: Installing copper granules on an existing roof can eliminate algae. Truth: Copper granules have not been proven to eradicate existing algae colonies.

Effective Solutions for Algae Growth

If you notice dark/black or green streaks on your roof, it’s a sign of algae growth. The impact of this growth is not just aesthetic. It can lead to poor drainage, make the roof slippery, potentially lift shingles, and even cause premature deterioration.

So, how do you address this?

  • Anti-Algae Solution: A mixture of water, bleach, and Tri-Sodium Phosphate (TSP) can be used to wash the roof shingles. Apply this solution at low pressure, wait for about 15 minutes, and then rinse with low-pressure water. It’s essential to protect plants and shrubs during this process. Power washing is not recommended.
  • Professional Help: If you’re unsure about the DIY approach, consider seeking help from roofing contractors in Clearwater FL. Dean Roofing Company, for instance, offers specialized services to address algae growth and ensure the longevity of your roof.
  • Regular Maintenance: Regular roof check-ups and maintenance can prevent the onset of algae. It’s always better to address the issue in its early stages than to deal with a full-blown problem.

In Conclusion

Algae growth on roofs is a concern that many homeowners face. However, with the right knowledge and approach, it’s a problem that can be effectively addressed. Whether you’re considering roof replacement in Clearwater or just need a roof repair service in Clearwater Florida, it’s essential to be informed and choose a trusted service provider like Dean Roofing Company to ensure the best results.
