Drone Roof Cleaning Singapore
Metal, tile and membrane roofs cleaned from the air, from S$1,200. Singapore's humidity grows algae and lichen on any roof that holds moisture — we remove it with no foot traffic, no fall risk and no membrane damage.
Drone roof cleaning in Singapore starts from S$1,200 for most commercial and industrial roofs, priced by area and growth level. The drone removes algae, lichen and moss using deionised water without anyone stepping onto the roof — which matters most on waterproofing membranes, where foot traffic during maintenance is a common cause of later leaks.
Key takeaways
- Price: From S$1,200 by area and biological growth level.
- Best cases: flat membrane roofs and large profiled metal spans (warehouse, factory).
- Membrane roofs: zero foot traffic is the main argument, not cost.
- Deferring costs more. Untreated growth turns a cleaning job into a recoating job.
- Bundle with solar. Cleaning roof and array in one mobilisation beats two visits.

Why roofs in Singapore grow things
Persistent humidity, heavy rainfall and year-round warmth make Singapore roofs an ideal substrate for algae, lichen and moss. On a metal roof this holds moisture against the coating and accelerates corrosion. On tiles it lifts and displaces them. On a membrane it retains water where the membrane is designed to shed it.
Left long enough, biological growth turns a cleaning job into a recoating or replacement job. The cost gap between those outcomes is the reason roof cleaning is worth scheduling rather than deferring.
Roof types we handle
| Roof type | Suitability | Notes |
|---|---|---|
| Flat membrane | Excellent | Strongest case for drone work — nothing touches the waterproofing layer. |
| Metal / profiled sheet | Excellent | Large continuous spans cover fast. Common on warehouse and factory roofs. |
| Clay / concrete tile | Good | Low pressure; loose or cracked tiles are identified rather than dislodged. |
| Polycarbonate / skylight glazing | Good | DI water only. Fragile panels nobody should stand on regardless. |
| Green / planted roof | Case by case | Depends on planting layout and what actually needs cleaning. |
The membrane argument. If your roof has a waterproofing membrane still under warranty, the strongest reason to use a drone is not speed or cost — it is that nothing touches the membrane. Foot traffic during maintenance is a common cause of later leaks, and those leaks are difficult to attribute once the contractor has left site.
Drone roof cleaning cost
| Roof | Typical price (SGD) | Notes |
|---|---|---|
| Small commercial roof | From S$1,200 | Minimum mobilisation applies |
| Mid-size industrial roof | From S$2,000 | Light to moderate algae |
| Large warehouse / factory roof | From S$3,000 | One to two days |
| Heavy lichen or moss | Adds 20–40% | Additional passes required |
| Roof + solar array bundled | Single mobilisation | Materially cheaper than two visits |
Where a roof carries a solar array, cleaning both in one mobilisation is substantially cheaper than separate jobs — see solar panel cleaning. Blocked roof drainage is often found at the same time; see gutter cleaning.
What we spot while we are up there
A cleaning flight puts a high-resolution camera over every part of your roof. We flag what we see — ponding, displaced tiles, corroded fixings, blocked outlets, damaged flashing — as part of handover. It is not a formal condition survey, but it routinely catches things worth knowing before they become a leak. A formal condition survey is a separately regulated service that we do not provide.
Frequently asked questions
How much does drone roof cleaning cost in Singapore?
Drone roof cleaning starts from S$1,200 for most commercial and industrial roofs, priced by area and biological growth level. Heavy lichen or moss needs additional passes and prices higher than light algae.
Why do roofs in Singapore grow algae and lichen?
Persistent humidity, heavy rainfall and year-round warmth make Singapore roofs ideal for algae, lichen and moss. On metal roofs growth holds moisture against the coating and accelerates corrosion. On membranes it retains water the membrane should shed.
Can drones clean warehouse and factory roofs?
Yes. Large profiled metal spans are among the best cases for drone cleaning — continuous surfaces cover quickly, and nobody has to walk across fragile roof sheets or skylight panels to reach them.
