Roof Cleaning Cost: How to Estimate Your Project
Commercial roof cleaning typically costs $0.20–$0.60 per square foot in South Florida. Roof type, pitch, biological growth, and access drive the final number — and drone soft-washing removes the expensive parts of that stack.
How much does roof cleaning cost per square foot?
Commercial roof cleaning in South Florida typically runs $0.15–$0.55 per square foot. Flat TPO/EPDM membranes are the cheapest at $0.15–$0.35, asphalt shingle and metal sit in the middle at $0.20–$0.45, and tile is the most expensive at $0.30–$0.55. Heavy algae or lichen growth adds a 15–30% premium, and bi-annual maintenance plans cut per-visit cost by 20–30%.

Drone cleaning, answered
How much does roof cleaning cost in South Florida?+
Commercial roof cleaning in South Florida typically costs $0.15–$0.55 per square foot, depending on roof material. Flat TPO/EPDM membranes sit at the low end ($0.15–$0.35), asphalt shingle and metal in the middle ($0.20–$0.45), and tile at the top ($0.30–$0.55). Drone soft-washing avoids the harness and foot-traffic premium that drives manual quotes higher.
Which roof type is the most expensive to clean?+
Tile roofs (Spanish, concrete, or clay) are the most expensive to clean because they're fragile, steep, and require careful soft-wash chemistry to avoid damaging the underlayment. Drone cleaning is particularly cost-effective on tile because there is zero foot traffic and zero risk of cracking tiles during the work.
Does heavy algae or lichen growth change the price?+
Yes. Established algae or lichen typically adds a 15–30% premium because multiple passes are needed for full removal. A maintenance cycle (bi-annual or quarterly) cuts this cost permanently — recurring roofs never build up to the heavy-growth tier.
Will drone soft-washing void my roof warranty?+
No. Drone soft-washing uses low-pressure detergent application followed by a pure-water rinse with zero foot traffic, which keeps every major shingle, tile, TPO, and EPDM warranty intact. Manual cleaning that requires walking the roof can put granule loss or seam wear on a future warranty claim.
Why one roof cleaning quote can be 3x another
Hand-cleaning a steep tile roof costs nothing like brushing a flat TPO membrane. Knowing the variables prevents getting overcharged — or under-bid for the wrong method.
- Pitch — steep roofs require harness systems
- Material — tile, shingle, metal, TPO, EPDM all differ
- Square footage — large roofs scale by tier
- Algae/lichen severity — multiple passes may be needed
- Access — gated communities and tall buildings add cost
- Roof age — fragile roofs need gentler methods
Drone soft-washing — same chemistry, no foot traffic
Our drones apply biodegradable soft-wash solution from above, then rinse with pure water. Zero foot traffic preserves warranties and eliminates the harness premium that drives manual quotes higher.
