Florida's heat and humidity create the perfect breeding ground for algae, moss, and mildew on your roof. Those ugly black streaks? That's Gloeocapsa magma — a cyanobacteria that feeds on the limestone filler in your asphalt shingles, causing premature deterioration and thousands of dollars in damage if left untreated. American Roofing FL provides professional soft wash roof cleaning across Polk County that safely removes algae, moss, and black streaks without damaging your shingles.
Soft washing is the only safe method for cleaning shingle roofs. Unlike pressure washing — which strips granules, voids warranties, and accelerates shingle failure — our low-pressure soft wash system uses specialized cleaning solutions to kill algae at the root and restore your roof's appearance. We clean shingle, tile, and metal roofs throughout Winter Haven, Lakeland, and all of Polk County.

Services
From algae and black streak removal to preventive treatments, American Roofing FL keeps your roof clean, healthy, and looking its best across Polk County.
Our soft wash system uses low-pressure application — no more than a standard garden hose — combined with professional-grade, biodegradable cleaning solutions that kill algae, mold, and mildew at the root. This is the only cleaning method recommended by shingle manufacturers including GAF and Owens Corning. It safely removes years of buildup without stripping protective granules or voiding your warranty.
Black streaks caused by Gloeocapsa magma are the most common roof staining issue in Central Florida. Left untreated, this algae feeds on the limestone filler in your shingles, breaking down the granule bond and causing premature deterioration. Moss traps moisture against the roof surface, accelerating rot and decay. We eliminate both with targeted soft wash treatments that restore your roof's original appearance.
After cleaning your roof, we apply a preventive algae treatment that inhibits regrowth for an extended period. Florida's constant humidity means algae will always return eventually, but preventive treatment significantly extends the time between cleanings — saving you money in the long run. This treatment is safe for all roof types and won't affect your landscaping or gutters.
Benefits
Professional roof cleaning does more than improve appearance — it protects your investment and extends the life of your roofing system.
Black algae streaks make even a newer roof look old and neglected. Professional soft wash cleaning restores your roof to its original color, dramatically improving your home's curb appeal. If you're selling your home, a clean roof makes a strong first impression and eliminates buyer concerns about roof condition.
Gloeocapsa magma algae feeds on the limestone filler in asphalt shingles, weakening the granule bond and accelerating wear. Regular cleaning removes this biological threat and can add years to your roof's lifespan. A $400 cleaning is far cheaper than a $15,000 premature roof replacement.
Moss and lichen trap moisture against your roof surface, leading to wood rot in the decking underneath. Algae growth can lift shingle edges, creating entry points for wind-driven rain. Mildew in attic spaces can spread to insulation and framing. Cleaning your roof prevents these cascading problems before they require expensive repairs.
Your roof accounts for up to 40% of your home's visible exterior. A stained, algae-covered roof reduces your property's perceived value and can trigger lower appraisals. HOAs in many Polk County communities require clean, well-maintained roofs. Regular cleaning protects your home's value and keeps you in compliance.
