How to Effectively Combat Roof Algae

Roof algae, characterized by unsightly black mold-like stains and streaks, can be a common concern for homeowners. Not only does it affect the aesthetic appeal of your home, but it can also lead to misconceptions about the health of your roofing. At Dean Roofing Company, we understand the importance of maintaining a pristine roof, and we’re here to guide you through the process of addressing and preventing roof algae.

Understanding Roof Algae

Roof algae, scientifically known as Gloeocapsa magma, predominantly appears on light-colored asphalt shingles. Contrary to popular belief, this blue-green algae is harmless to your roofing material. Its presence is more common in regions experiencing warm and humid summers. While it doesn’t pose a structural threat, it can diminish the visual appeal of your home.

Effective Algae Removal Techniques

If you’ve noticed the onset of algae on your roof, don’t panic. There are efficient ways to address this:

  • Roof Replacement: This is a more drastic measure and is only recommended if your shingles are nearing the end of their lifespan. Opting for darker shingles can help mask future algae stains. Alternatively, shingles infused with copper granules can be a deterrent to algae growth.
  • Bleach Solution: A cost-effective method involves using a mix of water and bleach in equal proportions. This solution can be sprayed onto the affected areas to eliminate the algae. However, it’s crucial to avoid using pressure washers as they can damage the shingles. Before applying the bleach solution, ensure you wet the surrounding plants and rinse them thoroughly afterward to prevent any damage.

Preventing Future Algae Growth

Prevention is always better than cure. To ensure that the algae doesn’t make a comeback:

  • Metal Strips: Place 6-inch-wide strips of zinc or copper under the shingles near the roof’s peak. Leaving a small portion exposed ensures that when it rains, metal molecules wash down, effectively preventing algae growth. This method is evident in homes with copper flashing around chimneys, where the roof areas below remain algae-free.
  • Regular Maintenance: Engaging with a reputable roofer in Clearwater FL, like Dean Roofing Company, can ensure regular check-ups and maintenance. This proactive approach can help in early detection and prevention of algae growth.

Moss Buildup on Roofs

In addition to algae, moss buildup can be another concern. If you notice moss on your roof, it’s essential to address it promptly. Begin by scrubbing the moss off with a brush, followed by the bleach treatment mentioned above.
