Roof pressure washing in Miami, FL
Miami roofs are tile, flat, shingle and metal, and humidity grows algae and mildew on all of them. We soft wash with a roof-safe cleaner, match the method to the material and clear the gutters before and after.
Roof washing advice usually assumes asphalt shingles. In Miami you are as likely to have concrete or clay tile, a flat roof with a membrane, or metal, and each one needs a different approach. None of them should be blasted with a high-pressure washer.
Humidity, heat and summer rain keep roofs damp, and algae and mildew follow. In South Florida the black stains are commonly an algae called Gloeocapsa magma. On tile it shows as dark streaks and blotches, often first on shaded slopes. Flat roofs collect a dirt film and stains where water ponds. Saharan dust in summer settles over all of it.
Tile needs the most care. Tile makers' care guides, citing Tile Roofing Institute guidance, cap cleaning pressure at about 1,200 psi and call for a cleaner that is compatible with concrete, since some products change the pH or etch the surface. They also say to step on the bottom few inches of the installed tile, where tiles overlap. A soft wash runs at a small fraction of that pressure, and we plan the route across the roof before the first step.
On flat roofs we use a membrane-safe cleaner, wash at low pressure and clear the drains and scuppers so water leaves the roof. Miami-Dade and Broward counties form Florida's High-Velocity Hurricane Zone, where roofing products need a Miami-Dade Notice of Acceptance. We clean. Repairs and re-roofing go to a licensed roofer, and when we see cracked tile or lifted edges we photograph them for you.
Concrete and clay tile are common on Miami roofs, along with flat roofs and some shingle and metal. Humidity and shade grow algae and mildew on all of them. On tile we limit pressure, choose a cleaner that is compatible with concrete, and step where the tiles overlap, because tile cracks when it takes weight in the wrong place.

What grows on a roof, and how we clean each type
The right method depends on the roof material. We match the cleaner and the footing to it.
| Roof type | What grows or builds up | How we clean it |
|---|---|---|
| Asphalt shingle | Dark algae streaks, moss, and lichen | Roof-safe cleaner, low-pressure rinse, never a pressure blaster |
| Concrete or clay tile | Dark algae, mildew, and moss in the valleys | Soft wash, careful footing, and a rinse that follows the tile pattern |
| Flat or low-slope roof | Mildew, dirt film, and standing-water stains | Low-pressure wash with a membrane-safe cleaner, drains cleared |
| Metal | Dirt film, mildew, and oxidation | Gentle wash and rinse that will not scar the coating |
On asphalt shingles the dark streaks are usually a cyanobacterium called Gloeocapsa magma, which feeds on the limestone filler in the shingle and spreads on the wind, as the Asphalt Roofing Manufacturers Association explains. Warm, humid, shaded roofs grow it fastest.
Soft wash or pressure washing?
This is the question that decides whether a roof cleaning helps your roof or hurts it.
| On your roof | High-pressure blasting | Our low-pressure soft wash |
|---|---|---|
| Shingles | Knocks off protective granules. | Granules stay in place. |
| Algae and mildew | Roots stay and streaks return sooner. | Cleaner kills growth at its base. |
| Water intrusion | Can force water under the roof surface. | Gentle flow that follows the way rain runs. |
| Tile, flat, and metal | Can chip tile and scar coatings and membranes. | Safe on tile, flat roofs, metal, and shingle. |
We use a soft wash on every roof. The cleaner does the work, and the water only carries it off. That is slower than blasting, and it is the reason your roof comes out of it in one piece.
How we wash a roof
Gutters first, roof second, gutters again at the end.
- 1
We inspect and plan
We check the material, the pitch, the condition of the surface, and the safest way up. Loose or damaged areas get flagged before we start.
- 2
We clear the gutters
Debris comes out first so the rinse has a clear path and the roof does not wash dirt into a full trough.
- 3
We protect the plants
Shrubs and flower beds under the roof line are wet down and covered.
- 4
We apply the roof-safe cleaner
The cleaner goes on at low pressure and sits long enough to kill the growth at its base.
- 5
We rinse gently
A low-pressure rinse carries the cleaner and the dead growth down and off, the way rain would.
- 6
We flush the gutters again
Runoff from the roof leaves through the gutters and downspouts, so we flush them a second time.
- 7
We photograph the result
You get before and after photos and a note on anything we saw that needs a roofer.
Streaks fade as the cleaner works. The rinse only carries them off.
Before and after: a roof soft washed
The same roof, photographed from the same spot before and after.
Safety, and what we leave to roofers
Roofs are dangerous places. We use the right ladder angle (see NIOSH guidance), we walk only on surfaces that can take it, and we never use high pressure. If a roof is too steep, too fragile, or too damaged to wash safely, we say so.
We clean roofs. We do not repair or replace them. When we find damaged roofing, we photograph it and tell you plainly, so a licensed roofer can take it from there.

Roof pressure washing questions, answered
How much does gutter cleaning cost in Miami?
The price depends on the feet of gutter, the number of stories, how packed the runs are and whether guards are installed. Many Miami homes have only short gutter runs over entries and garages, which keeps the job smaller. Call with your ZIP code and we quote by phone.
How much does roof cleaning cost in Miami?
It depends on the roof size, the material, the pitch and how much algae is on it. A one-story tile roof and a two-story flat roof are different jobs. Tell us the roof type and the stories and we quote by phone.
When is the best time to clean gutters in Miami?
Early May matters most, before the wet season starts on May 15. A second visit between mid-October and December clears the debris left by hurricane season.
How often should a Miami tile roof be cleaned?
Every two to three years suits most roofs. Shaded slopes and roofs under trees grow algae sooner.
Do you clean gutters and roofs after a hurricane or tropical storm?
Yes. Storms leave fronds, branches and shredded leaves on the roof and in the trough. After a named storm we move cleanups to the front of the schedule and flush every downspout.
Does my Miami home need gutters?
Not always. Many Miami homes shed water from the roof edge. If you have gutters or downspouts, we clean them. If you do not, a roof wash and a check of the drains and the ground along the drip line still protect the house.
Is it safe to pressure wash a tile roof in Miami?
Pressure is the risk. Tile makers' care guides cap cleaning pressure at about 1,200 psi and warn that some cleaners can etch concrete. We use a soft wash and a concrete-compatible cleaner, and we step only where tiles overlap.
Can you clean a tile roof in Miami without damaging it?
Yes, with a soft wash, a concrete-compatible cleaner and careful footing. Our pressure stays far below the 1,200 psi ceiling that tile makers set.
Do flat roofs in Miami need cleaning?
Mildew, dirt film and ponding stains build up, and drains can clog. We wash with a membrane-safe cleaner and clear the drains and scuppers.
How soon will the black streaks come back?
Algae spreads on the wind, so it can return, usually on shaded slopes first. Most roofs hold up two to three years between washes.
Dark streaks on your roof?
Call and tell us the roof material and what you see. We quote by phone and find a day that works.
