Roof Cleaning in Lakeland, FL – Soft Wash Results by Regal Rinse Solutions

Black Algae Streaks on a Lakeland Roof — Before It Caused Real Damage

That dark streaking you see on roofs across Polk County isn't just dirt — it's Gloeocapsa magma, a type of algae that feeds on the limestone filler in asphalt shingles. Left untreated, it degrades the shingle granules over time, shortening roof lifespan and voiding manufacturer warranties. This Lakeland homeowner acted at the right time: the streaking was visible but hadn't yet caused structural damage.

Many homeowners also don't realize that visible roof algae can affect homeowner's insurance — some carriers require periodic cleaning as a condition of coverage.

Soft Washing — The Only Safe Method for Shingle Roofs

We use the manufacturer-recommended soft wash method for all shingle roofs. High-pressure washing strips granules, voids warranties, and can force water under shingles — creating the moisture damage it's supposed to be cleaning up after. Our low-pressure soft wash delivers a biodegradable cleaning solution across the entire roof surface, kills the algae at the root, and rinses clean without touching a single shingle with damaging pressure.

• Soft wash only — zero high-pressure water on shingles
• Biodegradable treatment kills algae, moss, and lichen at the root
• Shingle granules fully preserved — warranty remains intact
• Dark streaking eliminated across the entire roof
• Post-treatment applied to slow future organic regrowth
