Roof
The black streaks on Florida roofs are Gloeocapsa magma — a hardy cyanobacteria that feeds on limestone in asphalt shingles and quietly shortens their lifespan. The cheap fix is high-pressure water, which strips the protective granules along with the algae. We use a low-pressure soft wash with carefully metered cleaners that kill the algae at the cell, then a recurring prevention rinse keeps it from coming back.
Full roof assessment before treatment — pitch, condition, problem areas.
Low-pressure soft-wash application of biocide blend tuned to algae load.
Targeted treatment on north-facing and shaded planes where loading concentrates.
Gentle rinse and runoff control to protect landscaping.
Before/after documentation + recurrence baseline for the next visit.
Why this routine matters in Florida
High pressure removes algae in 30 minutes — and 5 years of shingle life with it. The granules on an asphalt shingle are what protect it from UV; once they're stripped, the underlying mat ages much faster. Soft wash kills the algae at the cellular level and lets a gentle rinse carry it away.
Florida humidity + airborne spores means a freshly-cleaned roof will start re-accumulating within months. A recurring prevention rinse keeps the cell count low enough that visible streaking never returns — it's the cadence, not any single wash, that protects the look and lifespan.
Asphalt shingle, metal standing seam, tile, and TPO each tolerate different concentrations, dwell times, and rinse pressures. Our routine starts with a roof-type assessment so the treatment matches the substrate.
Common questions
Most asphalt-shingle roofs benefit from a treatment every 12–18 months, with lighter prevention rinses in between for shaded or north-facing planes. Metal and tile roofs typically run longer between visits.
Properly diluted soft-wash is safe for established landscaping when applied with runoff control — pre-watering plant beds, monitoring downspout discharge, and rinsing foundation plantings after. We treat protection of the landscape as part of the work.
Because the cure shortens the patient's life. Power-washing strips the granules that protect the shingle from UV, often leading to premature aging and leaks. Soft-wash + recurring care keeps both the roof and its appearance intact.
It restores curb appeal and protects the existing roof investment. It's not a single-event ROI calculation — it's preventative maintenance that compounds: an unmaintained shingle roof in Florida can age 5+ years faster than one on a care routine.
