Those black streaks are alive
The dark streaks running down a Florida roof are mostly algae. Lichen and moss can grow on top of it, especially on shaded slopes. Left alone, it spreads across the roof and holds moisture against the shingles or tile.
Pressure washing a roof is the wrong tool. It can strip granules off shingles and crack or loosen tile. We soft wash: a cleaning solution applied without pressure, given time to work, and rinsed.
Shingle and tile
On shingle roofs, the solution kills the growth and the streaks fade as it rinses. Tile roofs collect dirt in the channels and around the ridge, so we work section by section and rinse each one clean.

- Ridge caps and valleys
- Roof edges, gutter faces, and soffits below
What to expect
Most of the color change happens the same day. Heavy lichen can keep fading over the next few rains as the dead growth washes off. We'll tell you up front if your roof looks like that kind of job.
