The combination of intense UV exposure and daily humidity makes Jacksonville roofs particularly susceptible to black algae streaks and lichen growth. Our roof cleaning service uses a low-pressure application of zinc-based algicides that continue working for months after treatment.
We adjust our approach based on roof type: clay tiles in historic San Marco homes require different care than asphalt shingles in newer developments. For metal roofs common in coastal areas, we employ rust-inhibiting treatments that combat salt air corrosion.
The process includes gutter flushing to prevent post-cleaning debris accumulation - especially important before hurricane season. We also inspect for loose shingles or damaged flashing during service, providing homeowners with documentation for insurance claims.

Frequently Asked Questions
Is roof cleaning safe for my aging shingles?
Our soft wash system uses less pressure than garden hose sprayers. We avoid walking on roofs when possible, using extended reach wands for single-story homes common in Jacksonville neighborhoods.
How long until the black streaks disappear?
Most algae dies within 48 hours, with visible fading over 2-4 weeks as Jacksonville's rain naturally rinses away residual treatment.
