Your roof is your home’s first line of defense against the elements, but it’s also a surface prone to some unsightly issues like algae and mold growth. In the Orlando area, the humid climate creates the perfect environment for these problems to thrive. Left unchecked, algae and mold not only mar your roof’s appearance but can also compromise its structural integrity. At JA Edwards of America, we want homeowners to understand what causes these issues, how to prevent them, and the best ways to address them if they occur.
What Causes Algae and Mold Growth on Roofs?
Algae and mold are most commonly caused by excess moisture and organic material on the roof’s surface. Florida’s warm, humid climate provides the perfect breeding ground for these growths, especially on shaded roofs or areas with poor drainage. Algae typically appear as black or green streaks, often caused by a type of bacteria called Gloeocapsa magma. Mold, on the other hand, thrives in spots where leaves, twigs, and debris accumulate, trapping moisture.
Preventing Algae and Mold Growth
The good news is that algae and mold growth can be prevented with proactive care. Here are some key tips:
- Regular Roof Maintenance: Clean your gutters and remove debris from your roof to improve water drainage and reduce areas where moisture can collect.
- Trim Overhanging Trees: Overhanging branches create shade and drop leaves, which contribute to mold and algae growth. Keeping trees trimmed allows sunlight to dry your roof.
- Install Algae-Resistant Shingles: Modern roofing materials often come with algae-resistant properties. Consider these if you’re planning a roof replacement.
- Add Zinc or Copper Strips: These materials naturally inhibit algae and mold growth. Placing strips near the roof ridge can help prevent buildup.
Solutions for Algae and Mold Issues
If your roof already has algae or mold, professional cleaning is the safest and most effective solution. Avoid power washing, as it can damage shingles. Instead, opt for soft washing techniques that use low-pressure water and specialized cleaning solutions. For extensive damage, consult a roofing expert to determine if repairs or replacement are necessary.
