Roof soft washing at SoFlo starts at $299, and a full house exterior soft wash starts at $249. Where your roof lands inside that depends on a few things, and the gap between a good quote and a cheap one is worth understanding before you book.
What moves the roof price
Roof size and pitch. More square footage and a steeper slope both add time and difficulty. A low, walkable roof is faster than a steep barrel-tile roof that has to be treated entirely from a ladder and the ground.
Tile versus shingle. Barrel tile is common in Miami and it is fragile. It cannot be walked casually, so the work is slower and more careful. Shingle is more forgiving but needs the same gentle chemistry so the granules stay put.
How far gone it is. Light streaking rinses faster than a roof that has gone solid black and green. The worse the growth, the more product and dwell time the job needs.
Why the cheapest quote is a trap
The low roof quote in Miami is almost always someone planning to pressure wash it. That is the fast, cheap way, and it is the way that strips shingle granules, cracks tile, forces water under the tile, and voids your manufacturer warranty. The Asphalt Roofing Manufacturers Association's own guidance is low-pressure cleaning only.
So the real comparison is not $299 versus a cheaper number. It is a warranty-safe soft wash versus a pressure wash that can cost you a roof section later. Ask any roof quote one question: what PSI are you running up there? If it is anything near driveway pressure, keep looking.

Common Questions
Why is roof cleaning more than driveway cleaning?
A roof is slower, higher-risk work. It is done from a ladder or the ground with long-reach equipment, uses a cleaning solution rather than just water, and the crew is working around tile that cracks if you walk it wrong. The care is the cost.
Should I just pressure wash the roof to save money?
No. High pressure strips granules off shingles and cracks or displaces tile, and it voids most roofing warranties. A cheap pressure wash today is a roof repair bill later. Roofs get soft washed, always.
How long does a soft-washed roof stay clean?
Because soft washing kills the algae at the root instead of just removing the surface layer, a South Florida roof typically stays clean one to two years, often longer, versus months after a pressure wash.
