Short answer: what decides a roof cleaning in Lee County is not how dirty the roof is. It is what the roof is made of, what sits underneath it, and how old it is. The staining is the same organism on every house on the street, but the safe way to remove it is different on concrete tile than on a fifteen-year-old shingle, and getting that judgment wrong is how a cleaning turns into a repair.
Tile, shingle and metal are three different jobs
Most Fort Myers roofs are concrete tile, either the barrel profile or a flat interlocking tile, and the tile itself is not the fragile part. The fragile part is the underlayment beneath it and the fasteners holding it down. Tile carries weight badly at its edges and at the nose of each piece, so the real risk on a tile roof is foot traffic and ladder placement, not the cleaning solution. That is why we work from the perimeter wherever the layout allows, and why the route across a tile roof gets planned before anyone steps on it rather than during.
Architectural shingle is the opposite problem. The mat is tough enough to walk in cool conditions, but its entire weather defense is a layer of mineral granules pressed into asphalt, and those granules are finite. Every one washed into the gutter is protection that does not grow back. It is why the Asphalt Roofing Manufacturers Association's published guidance on algae discoloration points toward gentle, chemistry-led cleaning rather than pressure, and why a crew quoting a roof pressure wash on shingle is quoting damage. Metal, whether a standing-seam panel or the older 5V crimp still found on cottages near the River District, rinses easily but shows every scratch, and its factory coating is what keeps it from chalking, so it gets the lightest touch of the three.
What a soft wash visit actually looks like here
Before any solution is mixed we walk the property, not the roof. We are looking for what the runoff will reach: planting beds tight against the wall, a pool, an air-conditioning condenser, a screen enclosure, a neighbor's driveway a few feet away on a zero-lot-line build. Landscaping gets saturated with plain water first, because wet foliage cannot take up much of anything else, then rinsed again at the end. Downspouts get attention too, since a gutter is where the lifted algae actually ends up.
The clean itself is mostly waiting. Solution goes on at a pressure closer to a garden hose than a washer, it is left to work, and only then is it rinsed. The dwell is doing the job, not the water. A roof that goes quiet for twenty minutes in the middle of a visit is a roof being cleaned correctly. Wash water is kept away from the pool and away from the storm drain at the curb, because Florida's Department of Environmental Protection treats what enters a storm drain as reaching surface water directly, and in this county that means the Caloosahatchee.
The pool cage is part of the roof job
Nearly every home here has a screened enclosure, and it sits directly in the fall line of the roof above it. Screen mesh holds solution, aluminum framing streaks if residue dries on it, and the cage roof collects whatever comes off the tile. We rinse the enclosure as part of the roof visit rather than treating it as separate work, and when the cage itself needs cleaning it is better done in the same trip than a month later. Our pool deck and lanai cleaning covers that side of it. The same logic applies to an array on the roof: solar panels should be masked and rinsed as part of the plan, not discovered halfway through.
When we say no
Some roofs should not be cleaned, and saying so is part of the service. Tile that has gone brittle and cracks underfoot, lifted or missing shingles, visible daylight from the attic, an active leak, or underlayment already at the end of its life - on those the honest answer is that a cleaning spends money on the symptom while the roof needs a roofer. Washing a failing roof does not extend it. It only makes the failure better lit.
Timing it around the rainy season
From roughly June through September an afternoon storm is close to a daily event, and rain landing mid-dwell dilutes the solution and ends the visit early. That does not rule out summer, it makes it a morning job watched against the forecast. The dry season is easier to schedule, which is also why the calendar tightens from January onward. Wind matters as much as rain: a breezy day carries drift onto cars and neighboring property, and that is a legitimate reason to move a booking rather than push through it.
How long it lasts, and what actually extends it
Regrowth here is measured in seasons rather than years, and the honest range is wide because it depends on where you sit. A shaded north slope under an overhanging live oak in the McGregor corridor will show streaks again long before an open, sun-baked roof out in Gateway. Closer to the water, salt and standing humidity push it faster still. Three things genuinely stretch the interval: cutting back the branches that keep a slope damp, keeping gutters clear so water is not sitting at the eave, and the zinc or copper strip approach, where rain washing over the metal carries a trace down the slope and suppresses growth. Our gutter brightening pairs naturally with a roof visit for exactly that reason. None of these are permanent. They buy time.
HOA letters are a common reason people call
A large share of Lee County housing sits in deed-restricted communities, and roof appearance is one of the covenants that actually gets enforced. If a letter has already arrived with a deadline on it, mention that when you call. It changes how we schedule the work, not what we charge for it.
What a cleaning does not do
It does not change your roof's age, its underlayment, or how an insurer will assess it. Florida carriers have tightened what they will write on older roofs, and a clean roof is still an old roof - anyone implying otherwise is selling something. What a cleaning does do is remove the organism, stop lichen from rooting into the tile surface, and bring the color back. For the numbers behind the job, our Fort Myers roof cleaning cost guide breaks down what drives the price, and soft washing versus pressure washing goes deeper on the method question.
