Windermere FL roof after soft washing black streaks removed by JBC

This Windermere asphalt-shingle roof showed the dark streaking caused by Gloeocapsa magma algae — the cyanobacteria that thrives in Central Florida heat and humidity. The job required roof-specific soft washing at low pressure, not driveway-style high pressure.

Windermere and nearby Bay Hill / Horizon West roofs often show faster streaking on tree-shaded elevations. Soft wash is the ARMA-aligned approach for asphalt shingles in this market.

The cleaning challenge

Black streaks were concentrated on north-facing slopes and shaded valleys. High-pressure washing would risk granule loss and manufacturer warranty issues. Nearby landscaping needed pre-wetting and protection. The homeowner wanted a written warranty path and a firm price before work started.

Our process on this job

  1. Inspected roof pitch, access, downspouts, and plant exposure; photographed problem areas.
  2. Pre-wet and protected landscaping; staged soft-wash equipment for low-pressure application (~80 PSI).
  3. Applied biodegradable soft-wash solution to kill algae at the root, not just scrub the surface.
  4. Allowed proper dwell time, then low-pressure rinse and runoff management.
  5. Walked the property with the homeowner and confirmed post-treatment expectations.

Result and warranty

Visible black streaks were treated and the roof appearance restored without high-pressure damage. Qualifying soft-wash roof work includes JBC’s written 5-year warranty on roof soft washing against return of mold and mildew (terms apply). Typical Windermere roof soft-wash pricing falls in the metro band of $300–$600 depending on size and pitch.

Ongoing care

Keep gutters clear, trim heavy overhang where practical, and schedule an inspection when new streaking starts — usually every 2–3 years in humid Windermere microclimates.
