Soft washing cleans a roof with low water pressure and a cleaning solution that kills the algae and mold, so the tile is not blasted. High-pressure washing can crack or loosen roof tiles and wear down their surface, which is why tile roofs are soft washed rather than pressure washed.
Why tile roofs turn dark
The black streaks and dark patches on Florida tile roofs are usually algae and mold. Heat, humidity and shade let them spread across the tile.
It is more than looks. Growth holds moisture on the roof.
How a soft wash works
A soft wash applies a cleaning solution at low pressure. The solution does the work, killing the growth at the root, and a gentle rinse carries it away.
Because there is no high-pressure stream on the tile, the roof is cleaned without being blasted.
Where pressure washing still fits
Pressure cleaning is the right tool for hard surfaces like driveways, walkways and pool decks, and for removing algae and mold from them.
BrightView Window Cleaning offers both: professional pressure cleaning for the home, pool cage, driveway and walkways, and soft-wash roof cleaning. One customer's tile roof had not been cleaned in 5 years before Nick's crew soft washed it.
