Roof washing and roof cleaning in St. Augustine
Washed Clean washes roofs across St. Augustine, FL with a soft wash: a cleaning solution applied at low pressure that kills the black algae, moss and lichen, then rinses off. Shingle, concrete tile, clay tile and metal. Never a pressure washer on the roof. Free estimates, veteran owned. Call or text 904-587-9528.
Those black streaks running down a St. Augustine roof are not dirt. They are algae, and they feed on the limestone filler in asphalt shingles. Shade from the oaks, the humidity and a storm most summer afternoons give them everything they need, so a roof here can streak within a couple of years of going on.
Moss and lichen follow in the shady spots. They hold water against the roof, lift the edges of shingles and work into the gaps in tile. Removing them before they settle in is part of keeping the roof, not just the curb appeal.
A soft wash kills all of it at the root and rinses it away without touching the granules on a shingle or the finish on a tile. The same cannot be said for a pressure washer, which is why it never goes on a roof here.
The method
How the roof wash works
The solution goes on at low pressure and sits long enough to kill the algae, moss and lichen. Stubborn spots get a second application instead of more force. Then the roof is rinsed down along with the walls, windows and plants below it, so nothing dries on the house.
Gutters and downspouts are checked first so the runoff has somewhere to go, and the beds under the drip line are soaked and rinsed. Walking the roof is kept to what the job needs.
No pressure.
On the roof. Ever.

Straight talk
A pressure washer does not belong on a roof
High pressure strips the granules that protect asphalt shingles, cracks tile and forces water under the laps. Some roof warranties say so outright. A soft wash takes the algae off at a fraction of the pressure and keeps it off longer, because it kills it instead of blasting the top layer.
Questions
Roof washing questions
Is roof washing safe for shingles?
Yes, when it is a soft wash. It is designed to clean roofs gently without damaging shingles or other roofing materials. Pressure is what damages them, and it is never used.
How often should a roof be washed?
Typically once every 1 to 3 years, depending on shade, local weather and how fast the moss or algae comes back.
Why wash a roof at all?
Moss, algae and stains wear a roof down over time. Removing them helps the roof last, and a clean roof reflects more sun, which helps keep the house cooler.
Do you wash tile and metal roofs?
Yes. Shingle, concrete tile, clay tile and metal all get a soft wash, tuned to the surface.
