Roof washing in Bonita Springs.

Bonita Springs communities are wrapped in preserve and wetland — Bonita Bay, Pelican Landing, The Colony, Spring Creek — and that means humidity that barely drops and shade from mature buffer planting on a lot of these roofs. Add a wet season that runs for months and the dark streaking on the north slopes is not a question of if but of how soon, usually within two or three years of a new roof going on.

Our roof washing clears it with a low-pressure soft wash rather than a pressure wash, because the tile that most of these communities are roofed in cracks under foot traffic and dislodges under pressure. Solution kills the algae at the root, a gentle rinse takes most of it off, and the rest weathers away over the following weeks.

Preserve-adjacent runoff is handled deliberately: beds and buffer plantings pre-wet, solution at working dilution, everything rinsed down afterward. Where the walls and soffits below have gone the same way, soft washing is the same principle applied lower. More on the area in Bonita Springs.
