Rhythm City Commercial Roofing | Roofing Services in Franklin, TN 37069

The dark streaks or stains you see on many Franklin roofs are typically Gloeocapsa magma algae, which thrives in our humid climate. Yes, we professionally clean them! We use a specialized, low-pressure soft wash system with EPA-approved, biodegradable cleaners that safely remove the algae without damaging your roofing materials, restoring your roof's appearance and helping to preserve its lifespan.

Roof valleys are critical drainage points where two roof slopes meet, handling a high volume of water runoff. In our area, leaks often occur due to worn sealants, cracked flashing, or debris buildup causing water to back up. Our repair process involves a thorough inspection, careful removal of any debris, and the precise repair or replacement of flashing and underlayment with high-quality, waterproof materials to ensure a long-term seal and proper water flow.

Proactive maintenance is key. We recommend biannual inspections, especially after severe weather, to check seals and flashing. Keeping your roof, gutters, and valleys clear of leaves and debris prevents water backup. For algae, consider installing zinc or copper strips along the roof ridge—when it rains, trace amounts of metal wash down, creating an environment that inhibits algae growth. We offer maintenance plans to help local businesses stay ahead of these issues.
