The black streaks on Jacksonville roofs are caused by Gloeocapsa magma — a cyanobacteria that spreads across shingle surfaces and accelerates granule loss over time. High-pressure washing removes the visible stain but damages shingles; roof soft washing applies a biodegradable algaecide at very low pressure that kills the organism at the root and extends shingle life. Wash water is directed away from planted beds and hardscaping as practical during the rinse.
Most JAX roofs (1,500–2,500 sq ft) run $350–$750; larger, steeper, or tile roofs $750–$1,200.

Roof Soft Wash — common questions
What is roof soft washing and why not use a pressure washer?
Roof soft washing uses very low water pressure — similar to a garden hose — combined with a biodegradable algaecide. High-pressure washing strips granules from asphalt shingles, voids manufacturer warranties, and can force water under tiles. Soft washing eliminates the organism causing the staining without that damage.
How often does a Jacksonville roof need soft washing?
Every 2–4 years is typical for shingle roofs in Jacksonville. Homes under heavy tree canopy, facing north, or near water may see algae return sooner. Tile roofs generally need treatment less frequently.
Is roof soft washing safe for tile roofs?
Yes. The same low-pressure method applies to clay and concrete tile. The algaecide solution is safe for both shingles and tile materials. The quote reflects the roof type and pitch.
