Black Streaks on Your Roof

Living in a humid area with lakes and trees? You might soon notice black streaks on your roof shingles. These streaks are most likely caused by algae. While unsightly, algae itself doesn’t necessarily damage your roof. However, if left untreated, it can create a hospitable environment for moss and lichen to grow, which can cause significant problems.


Investing in Your Roof: Why Cleaning Matters

Cleaning your roof is an investment that can extend the lifespan of your shingles, saving you money on repairs or replacements down the road. In recent years here in Tallahassee, FL, we’ve seen a rise in homeowner inquiries about roof cleaning, after being required by their insurance company to have their shingles professionally cleaned due to the dark algae stains.


Don’t Let Algae Take Over: Clean Your Roof Now

Before cleaning your roof, always refer to your shingle manufacturer’s instructions for removing algae. Different shingle materials may require specific cleaning procedures. Certain shingle manufacturers suggest using a 50/50 bleach and water solution for cleaning roofs with algae growth. Apply the solution with a garden sprayer and let it sit for 20 minutes before rinsing with a low-pressure from a garden hose. To prevent plant damage from roof cleaning runoff, thoroughly rinse your landscaping with fresh water before, during, and after the process. Additionally, covering plants and bushes susceptible to overspray can provide extra protection. If cleaning your roof yourself feels like a challenge, a professional roof cleaning company can offer convenient and reliable service, giving you peace of mind.
