Is soft wash safe for my metal roof's painted finish?
Yes, with the right chemistry. Standard alkaline roof cleaners damage metal paint over time. We use pH-balanced solutions formulated specifically for galvalume, galvanized steel, and aluminum that clean without dulling or corroding the finish.
What causes the dark stains on my metal roof?
Salt deposits, algae, and mildew are the main causes. Coastal Tampa Bay properties add iron oxidation from Gulf salt air. Metal's smooth surface doesn't hold growth as long as tile grouting, but salt residue accelerates algae colonization.
Can I pressure wash my metal roof?
Not safely. High-pressure washing scratches the painted finish on most metal roofs and voids the manufacturer warranty. Soft wash cleans without surface contact — more effective and warranty-safe.
How often should I clean my metal roof in Tampa Bay?
Every 18–24 months for most Tampa Bay metal roofs. Waterfront and coastal properties near the Gulf or Bay should clean every 12–18 months due to accelerated salt air buildup.
