Tile and Barrel Tile Roof Cleaning in Miami — Zero Foot Traffic

Drone tile and barrel tile roof cleaning runs $0.30–$0.55 per square foot. Most Miami residential tile roofs fall between $800 and $1,800; HOA and commercial tile portfolios run $3,000–$15,000+ depending on roof count and size.

Yes — and the manufacturer warranty voids the moment foot traffic damages the tile. Eagle, Boral, and Ludowici tile is hollow, and a single misplaced step can crack a tile or break the bedding mortar. Drone soft-wash never touches the surface.

Yes. Soft-wash chemistry kills Gloeocapsa magma at the root — the cyanobacteria responsible for almost every dark streak on Miami tile. Pressure washing only blasts the visible layer and the spores recolonize within months. Soft-wash lasts 24–48 months.

It strips the protective glaze on glazed tile (allowing algae to recolonize faster), can crack hollow barrel tile from impact, and forces water under the tile lap into the underlayment. Soft-wash chemistry cleans deeper without any of that damage.

A tethered industrial drone — flown by an FAA Part 107 commercial pilot — carries a low-pressure soft-wash spray head fed by a ground pump. Biodegradable detergent is misted over the tile, dwells 5–15 minutes to kill algae and lichen at the root, then a pure-water rinse sheets the dead growth off. The drone never lands on the roof and no one walks the tile.

Barrel tile is hollow — air space below the curved profile. The tile is engineered to carry distributed load from above but not point load from a foot placed in the wrong spot. Eagle, Boral, and Ludowici warranties explicitly call out foot traffic as a damage cause and void coverage where the damage is traced to walking the roof.

Every major Miami tile system: Eagle, Boral, Ludowici, Entegra, Crown, US Tile, MCA, and Vande Hey Raleigh. Profiles include barrel/Spanish-S, flat concrete tile, low-profile, and clay tile. Chemistry is matched to glaze type — what works on glazed barrel is dialed differently for unglazed clay.

No. Pressure washing strips the protective glaze; soft-wash chemistry does not. The detergent works on the surface biological growth, not the glaze itself. Glazed tile stays glazed after cleaning — and the glaze is what makes future cleanings easier.

Pitch is irrelevant to a drone. The drone hovers at the same distance from the surface regardless of slope, so a 12/12 pitch is no harder than a 4/12. This is one of the biggest advantages over ground crews, who have to rig fall protection for anything over 6/12.

24–48 months before visible algae return on Miami tile, depending on tree cover, shade, and oceanfront exposure. Pressure washing on the same tile lasts roughly 6 months because the algae spores survive and recolonize. The chemistry, not the pressure, drives the duration.

$0.30–$0.55 per square foot. A typical 2,500 sqft residential barrel tile roof runs $800–$1,400. HOA communities get multi-roof portfolio pricing — a single mobilization covers multiple buildings, which significantly reduces per-roof cost.

No. Detergents are biodegradable. We pre-wet landscaping below the roof line before chemistry application — runoff is diluted on contact. Pool decks and pool water are rinsed clean of any overspray as part of the workflow.

HVAC units are pre-wet before soft-wash application — diluting any overspray that reaches the condenser coil. The unit fan can stay running during cleaning. There's no chemistry concentration that reaches the coil at a strength capable of corroding it.

Residential barrel tile roof: 1–3 hours. Multi-roof HOA portfolio: 1–3 days for the full community. The drone moves faster than a ground crew because there's no ladder work, no rope rigging, and no walking the roof.

We carry $2M commercial general liability plus dedicated UAS (drone) liability and hull coverage. COIs naming the homeowner, property manager, or HOA are issued before mobilization on every project.

Yes. Every flight is conducted under FAA Part 107 by a licensed commercial drone pilot. For controlled airspace near MIA, FLL, and PBI we file LAANC airspace authorizations before mobilization.

If dark streaks, green algae, or lichen patches lift off after soft-wash, the roof is cosmetic-soiled and cleaning is the right call. If you see cracked or slipping tiles, exposed underlayment, soft mortar at the ridge, or active leaks, those are structural issues cleaning can't fix. We send a 4K aerial inspection before quoting so you see the actual condition.

Often yes. Most Florida carriers underwrite roof condition annually using aerial imagery from EagleView, Nearmap, or their own drone flights. A tile roof flagged with heavy algae or lichen is more likely to be hit with a wind/hail surcharge or non-renewal. Cleaning before the carrier's next inspection cycle removes the visual flag. Always check with your specific carrier.

Yes. The drone hovers over any roof feature — valleys, hips, ridges, and roof-to-wall transitions all get equal coverage. Valleys are the heaviest algae zones on tile roofs because they stay damp longer, and they're also the hardest places for ground crews to reach safely.

Cleaned in the same visit. The drone works around solar arrays and skylights without disturbing the equipment. Solar panels themselves can be cleaned in the same mobilization for an additional per-panel cost.

No. The chemistry is pH-neutral and biodegradable. White concrete tile and light-color glazed tile come out cleaner than they went in — soft-wash lifts the soiling that makes them look gray rather than depositing anything new.

Quiet. The ground pump runs roughly 60–70 dB at the base — quieter than a leaf blower and dramatically quieter than a pressure washer (90+ dB). HOA communities can clean multiple roofs in a single morning without disturbing residents.

Yes. Annual contracts for HOA communities drop per-roof pricing 15–25% and lock in scheduling. We sequence the community over 1–3 mobilizations per year depending on size, and provide consolidated 4K documentation per roof for HOA board records.
