Drone Roof Cleaning in Miami & South Florida

Residential roofs run $0.25–$0.35 per sq ft with no minimum charge, most single-family homes land $500–$1,200. The higher small-roof rate covers mobilization, and it eases with size. Commercial roofs run $0.12–$0.25 per sq ft, also with no minimum, so the total follows roof area: $1,200–$2,375 at 10,000 sq ft, $4,800–$8,000 at 40,000 sq ft, and $10,364–$20,000 at 100,000 sq ft. Pricing is by square footage, material, and pitch, multi-roof and portfolio discounts apply.

No. Drone soft-washing uses low-pressure biodegradable detergent and pure-water rinse. It does not strip shingle granules or crack barrel tiles the way pressure washing does. It's warranty-friendly on every major Miami-Dade and Palm Beach roofing system.

Never. The drone hovers above the roof and applies the soft-wash solution from the air. No one walks on the roof and nothing contacts the surface, eliminating fall risk and granule loss in one step.

Yes. We routinely clean tile and flat commercial roofs ahead of Miami-Dade 40-year recertification and Florida SB-4D Milestone Inspections. The 4K geotagged photo set we deliver is what engineers, condo associations, and Unsafe Structures Boards expect for the cleaning portion of the inspection record.

A tethered industrial drone carries a soft-wash spray head fed by a ground-based pump. Biodegradable detergent is misted over the roof, dwells 5–15 minutes to remove algae and lichen down to the root, then a pure-water rinse sheets the loosened growth off. The drone never lands on the roof and no person walks the surface: zero foot traffic, zero microcracks, zero broken tiles.

Barrel tile, flat concrete tile, asphalt shingle, standing-seam and corrugated metal, TPO and EPDM membranes, modified bitumen, and clay tile. Chemistry and dwell time are dialed in per substrate. What works on a Boca Raton barrel-tile roof is not what works on a Doral warehouse TPO membrane.

No, the opposite. Most major roofing manufacturers (GAF, CertainTeed, Owens Corning, Eagle, Boral) explicitly warn against pressure washing and minimize foot traffic on warranted roofs. Drone soft-wash uses low-pressure biodegradable chemistry and zero contact, which is warranty-friendly across every major South Florida system.

It removes the growth itself, not just the color. Gloeocapsa magma (the black-streak algae endemic to South Florida roofs) and lichen are biological growths. Pressure washing only blasts the visible surface and the growth comes back within months. Soft-wash chemistry removes the organism down to the root, so the clean lasts far longer.

Gloeocapsa magma is the blue-green algae responsible for the black streaks on Florida roofs. It feeds on the limestone filler in shingles and the calcium in tile, and Miami's heat, humidity, and airborne spores make it grow aggressively. Left alone it spreads into a full black mat that holds heat, raises cooling costs, and shortens roof life. Soft-wash cleaning removes it down to the root so it doesn't simply regrow.

Every 12–24 months. Miami-Dade, Broward, and Palm Beach combine 9+ months of UV-driven growing season with salt air, humidity, and shade, ideal conditions for Gloeocapsa magma. Oceanfront properties on Miami Beach, Sunny Isles, and Hallandale Beach often need it every 12 months; inland and west Broward/Palm Beach can stretch to 24.

Algae and gloeocapsa start dying immediately and you'll see visible improvement the same day. Full whitening, where the dead biology weathers and rinses off completely, takes 7–14 days depending on rain and sun. Heavier lichen growth occasionally needs a second light application, which we note during the survey.

Yes, and on warranty-sensitive roofs, better, because the result depends on chemistry and coverage, not on someone standing on the tile. The drone delivers the same soft-wash solution and pure-water rinse to every plane, including steep and fragile sections a crew would avoid or damage, while the underlayment takes zero foot-traffic load.

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 and carry the certificate on every job site.

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

Yes. Detergents are biodegradable and rinsed with pure water. We pre-wet landscaping below the roof line and cover sensitive plantings before application. Pets stay inside during the dwell-and-rinse window (typically 60–90 minutes) and pool decks are rinsed clean of overspray as part of the workflow.

Most residential roofs finish in 1–3 hours. Mid-sized commercial roofs typically take 4–8 hours. Large warehouse roofs and HOA portfolios run 1–3 days. The drone moves faster than a ground crew because there's no ladder work, no rope rigging, and no walking the roof.

Yes, and it's one of the strongest reasons to use drones. Brittle barrel tile, aging shingle, fragile clay, and warranty-restricted TPO are all unsafe for foot traffic. The drone reaches every section of the roof from the air and leaves zero impact damage.

Yes. Every project includes 4K aerial footage and photo documentation of the roof before and after cleaning, delivered to the homeowner or property manager. Insurance carriers, HOA boards, and warranty providers routinely accept this documentation.

Salt cake, palm-frond debris, and dust film are our highest-volume Miami project type after a named system. We can mobilize a drone crew within 48–72 hours of a closure being lifted and work alongside roofers on punch-list cleaning ahead of insurance inspections.

If the black streaks, green algae, or lichen patches wipe off after soft-wash, the roof is cosmetic-soiled and cleaning is the right call. If you see lifted shingles, broken or slipping tiles, exposed underlayment, soft spots, or active leaks, those are structural failures cleaning can't fix. We send a 4K aerial inspection before quoting so you see the actual condition, and we'll tell you honestly when replacement is the better spend.

Indirectly, yes. Most carriers underwrite roof condition annually using aerial imagery from EagleView, Nearmap, or their own drone flights. A roof flagged with algae streaks or mildew is more likely to be hit with a wind/hail surcharge or coverage non-renewal. Soft-wash cleaning before the carrier's next inspection cycle removes the visual flag and protects renewal terms. Always check with your specific carrier.

Yes, most of them. Biological staining (algae, mildew, mold) lifts completely with soft-wash chemistry. Atmospheric staining (rust runoff from HVAC, copper drip lines, fertilizer overspray) lifts about 70–90% depending on age. Petroleum staining (asphalt leach, kitchen exhaust grease) is the hardest and may require targeted spot treatment before the full-roof rinse.

No. We pre-wet all landscaping below the roof line before chemistry hits the roof, which dilutes any runoff on contact. Detergents are biodegradable and substrate-matched, not the chlorine-bomb formulations that DIY ground crews use. Pool decks and pool water are rinsed clean of overspray as part of the workflow. We've cleaned roofs over orchid collections, koi ponds, and HOA-protected mangroves without incident.

Both remove algae, but the chemistry and dwell time matter. Cheap chlorine-bomb services use undiluted sodium hypochlorite at high concentrations, which bleaches the visible growth instantly but degrades shingle granules, corrodes metal flashings, and damages plants on contact. Engineered soft-wash uses substrate-matched detergents at controlled concentrations with measured dwell times: slower visible result, a longer-lasting clean, no warranty risk.

12–24 months before algae visibly returns, on asphalt shingle, metal, barrel tile and TPO/EPDM commercial membranes alike, depending on tree cover, humidity and oceanfront exposure. That is the cleaning cycle we recommend, and a recurring maintenance contract keeps the algae spore load from re-establishing between cleanings.

Often, yes. A black algae mat absorbs heat and raises attic and roof-deck temperatures; restoring tile or a reflective membrane to its original color reduces heat gain. The bigger financial win is roof life, controlling biological growth typically adds 5–10 years before replacement.

Mixed roofs are routine. The drone applies tile-appropriate cleaning solution and dwell on the sloped tile and a membrane-safe formulation on the flat TPO/EPDM section in the same visit: different chemistry, one mobilization, one documentation set.

Yes. While the drone is staged, we routinely extend cleaning to skylights, sun-tunnels, solar attic fans, gutters (visual rinse. Physical scoop-out is separate), and adjacent solar arrays. Bundling avoids a second mobilization fee, which is usually the largest single line item on small-job pricing.

Heavy long-neglected growth (thick lichen, deep gloeocapsa matting) may need a stronger solution and occasionally a second pass on the worst planes. We assess it in the survey and price it into the fixed quote, and the first deep clean resets the maintenance clock.

Late dry season (March–May) and early dry season (November–December) are ideal windows because algae growth slows and the rinse-off dries cleanly. Pre-hurricane season cleaning (April–May) doubles as inspection prep: algae and mildew often hide minor shingle, tile, or membrane damage that should be patched before storm season. Post-storm cleaning (October–November) removes wind-driven organic debris and the mildew bloom that follows tropical rainfall. We schedule year-round with no seasonal pricing premium.

Often, yes. Black streaks, algae and lichen make a sound roof look like it needs replacing, and buyers, inspectors and insurers reading aerial imagery (EagleView, Nearmap, drone reports) can flag it as deferred maintenance. A drone soft-wash removes the growth and brings back the original color for a small fraction of the cost of a new roof, and taking off growth that holds moisture against tile and shingle extends the life of the roof you already have. If the material itself is failing (lifted shingles, cracked tile, soft decking), replacement is the honest answer, and we will tell you so at the survey.
