Drone roof and facade cleaning in France: getting it done by the rules

Who it is for

• Homeowners in France, including non-resident owners, who want their roof treated without scaffolding or anyone walking on the tiles
• Property managers and co-ownership boards having roofs or facades treated
• Managers of commercial buildings, landlords and public bodies having cladding and roofs cleaned
• Roofers and cleaning firms subcontracting drone spraying who want to know what to require

What this guide does not do: The guide does not teach you to fly a spraying drone or start a roof-cleaning business · It recommends no commercial product: it tells you what to check on the label and data sheets · It does not replace a roofer's assessment of your roof or an asbestos professional's opinion

Introduction

Drone moss treatment makes a simple promise: treat a roof or facade with no scaffolding, no cherry picker and no one walking on the tiles. The promise holds for many buildings. But a spraying drone combines three sets of rules that clients often ignore: flight rules (a drone that releases a product does not fly in the open category), product rules (a moss killer is usually a biocide, with conditions of use) and site rules (asbestos, neighbours, run-off water). The provider answers for them, but you pay if one is mishandled: spots on the neighbour's car, product ending up in the stream, a damaged asbestos-cement roof.

This guide is written for whoever orders the treatment: homeowner, property manager, building manager. It tells you whether a drone suits your surface, which documents to require, which questions to ask, how to protect neighbours, how to get a co-ownership vote, which VAT applies, and how to sign off the job. The templates in the last chapter (request for quotes, notice to neighbours, general meeting resolution, comparison grid, completion report) can be copied by replacing the fields in [brackets].

The guide is up to date as of 21 October 2026. It relies on Regulation (EU) 2019/947 and the DSAC guide (safety directorate of the French civil aviation authority), the French rural code and the law of 23 April 2025 on plant protection products, biocide rules and the Certibiocide scheme, the labour code for asbestos, the civil code, the 1965 co-ownership law and the general tax code.

Before requesting a quote: is a drone suitable, and under which rules?

What a drone does well and what it does not

A cleaning drone is usually a spraying drone: it applies a treatment (moss, algae and lichen killer), sometimes a low-pressure rinse or a water repellent. The product is either carried in a tank or fed through a hose from a pump on the ground.

Three sets of rules on top of each other

1. Flight. A spraying drone releases material: it leaves the open category. The provider must fly under a specific-category framework (chapter 2).
2. Product. A roof moss killer is usually a biocide, subject to a marketing authorisation and conditions of use; if it were a plant protection product, aerial spraying on a roof would be prohibited (chapter 3).
3. Site. Possible asbestos, protection of third parties, run-off water, neighbours (chapters 4 and 5).

Five questions to ask yourself

1. What is the surface (tiles, slates, fibre cement, metal deck, render, cladding) and what condition is it in?
2. Was the building built before July 1997? If so, asbestos is a question.
3. What is around it: cars, pool, vegetable garden, conservatories, stream, street?
4. Who decides: you alone, a co-ownership, a landlord?
5. What result do you expect: a curative treatment, visible cleaning right away, protection (water repellent)?
