Roof Cleaning and Algae Removal in Pace, FL
Those black streaks running down your roof aren't dirt and they aren't going to wash off in the rain. They're gloeocapsa magma — a hardy, roof-specific algae that thrives in the warm, humid Gulf Coast climate. Left alone, it spreads, locks moisture against your shingles, and shortens the usable life of your roof by years. Pace Pressure Washing Pros removes it safely using the soft wash technique recommended by every major shingle manufacturer.
We clean roofs across Pace, Milton, Bagdad, and East Milton. Call (850) 845-9110 for a free quote.
Why Roof Algae Is a Bigger Problem Than It Looks
Gloeocapsa magma feeds on the limestone filler in modern asphalt shingles. As it eats, it holds moisture against the shingle surface — accelerating granule loss, breaking down the shingle's UV resistance, and giving regular mildew and lichen a foothold. A roof with severe algae growth can lose five to ten years of usable lifespan compared to a roof that's been kept clean.
It also affects your home's value. Even if the algae isn't actually damaging the roof yet, buyers and home inspectors see black streaks and start subtracting from the offer.
Why You Should NEVER Pressure Wash a Shingle Roof
Asphalt shingles are made up of a fiberglass mat coated with asphalt and topped with mineral granules that protect the asphalt from UV degradation. High-pressure water — anything above ~500 PSI — physically blasts those granules off the surface. Once they're gone, the shingle is exposed and starts deteriorating fast.
Every major shingle manufacturer (GAF, Owens Corning, CertainTeed, Tamko) explicitly states that pressure washing voids the shingle warranty. The Asphalt Roofing Manufacturers Association (ARMA) recommends only soft wash cleaning for asphalt shingle roofs.
Our Roof Cleaning Process
- Inspect the roof for damage and severity of growth.
- Protect landscaping, downspouts, and exterior plants.
- Apply a custom-mixed soft wash solution at low pressure across the roof surface.
- Let the solution dwell, killing algae, mildew, and lichen.
- Rinse with low-pressure water; remaining streaks fade over the next 30–60 days.
Other Roof Types We Clean
- Asphalt shingles (most common)
- Metal roofs
- Tile roofs (clay and concrete)
- Slate roofs (with extra-low pressure)
