Jacksonville roofs face triple threats: relentless sun degrades shingles, humidity breeds black streaks, and tropical storms deposit debris. Traditional pressure washing strips protective granules—our soft wash system cleans without damage.
We start by inspecting for compromised shingles or tiles that need repair before cleaning. Using a proprietary blend of sodium hypochlorite and surfactants, we eliminate Gloeocapsa magma (the bacteria causing black streaks) at the root. The solution dwells for 15-20 minutes to penetrate deeply before being rinsed at under 500 PSI—about 1/10th the pressure used by inexperienced companies.
For historic homes in St. Augustine with clay barrel tiles, we employ even gentler techniques. The result isn't just cosmetic; removing organic growth prevents moisture retention that leads to rot and premature replacement.

Frequently Asked Questions
Is roof cleaning safe for my landscaping?
We pre-wet plants with pH-neutral water and use biodegradable cleaners. Sensitive species like azaleas get additional protection with physical covers.
Why do black streaks keep coming back?
Many companies just bleach surface stains. Our treatment penetrates the shingle's porous surface to kill the root structure of the bacteria.
