The drone and facade and roof renovation – a revolution for building maintenance
The drone and facade and roof renovation – a revolution for building maintenance
The maintenance of facades and roofs is a crucial issue for local authorities, social landlords, and property owners. It is not only a matter of preserving heritage but also of safety, thermal comfort, and aesthetics. For a long time, these operations relied on demanding traditional methods: scaffolding, cherry pickers, work at height, and long intervention durations... However, in recent years, a technology has revolutionised these practices: the spraying drone. Initially used for photography, it has now become a leading operational tool in the construction sector. Why is this change so important? What are the real advantages of drones for the renovation and maintenance of facades and roofs? This article offers a comprehensive exploration of this technological revolution.
The advantages of drones in building renovation
An unmatched execution speed
One of the main contributions of drones is their ability to drastically reduce intervention times. A facade treatment project on several buildings, which would have taken several weeks with cherry pickers or scaffolding, can be completed in just a few days with a drone. This is due to the flexibility of deployment: no need for infrastructure setup, no closure of access or prolonged evacuation of the premises. Drones can operate in the morning, treat one building, and move on to the next in the afternoon.
This reduction in timelines is crucial for property managers. It not only allows for better planning of operations but also reduces the impact on residents, particularly in social housing where the intervention period should be as short as possible.
Enhanced safety for operators
Working at height is one of the most hazardous activities in the construction sector. According to the INRS, nearly 20% of serious accidents are related to falls from height. The use of drones eliminates this risk by preventing operators from climbing ladders, roofs, or unstable platforms. The pilot remains on the ground, at a safe distance, while the drone handles the spraying.
This approach meets an increasing requirement from companies: to protect workers, improve working conditions, and limit downtime due to accidents. It is also a strong point for public clients, who are very attentive to the "safety" aspect of interventions.
A precise and uniform application
Drones are equipped with spraying nozzles controlled by a GPS and gyroscopic system, ensuring uniform and regular coverage of treated surfaces. Unlike a human operator, the drone is not subject to fatigue or variations in technique: it sprays with the same precision from the start to the finish of the project.
This guarantees superior application quality with no overconsumption of product or poorly covered areas. The result is a longer duration of effectiveness and a uniform visual appearance, highly appreciated in the context of rehabilitated or recently repainted residences.
An ecological and responsible approach
Drones use medium-sized tanks (generally between 10 and 30 litres) and can target very precise areas to be treated. This control allows for a reduction in the quantities of product needed. When combined with bio-sourced and biodegradable antifungal solutions (such as those based on natural enzymes or pelagic acid), they enable performance while respecting local ecosystems.
Some companies, like FlyRenov, even go further by pumping water from rivers that are not classified under water stress during drought periods, to avoid using the municipal network. These responsible practices are increasingly demanded in public tenders and certified projects.
Concrete use cases
Facade treatment in dense urban areas
In city centres or residential neighbourhoods, using scaffolding can be complex: lack of space, clutter in public areas, traffic constraints... Drones allow for quick interventions without blocking roads or disturbing residents. They are particularly suited to facades facing north or those prone to vegetation pollution (lichens, green algae).
Cleaning fragile or inaccessible roofs
On old buildings or those with complex roofs (steep slope, porous tiles, skylights), drones preserve the integrity of the covering. They avoid direct supports, human passage, thus prolonging the lifespan of the covering while ensuring precise antifungal treatment.
Interventions on large housing estates
For social landlords, drones allow for rapid treatment of multiple buildings ranging from 5 to 12 storeys. They adapt to complex configurations (inner courtyards, difficult angles, significant heights) while ensuring a high level of safety. Co-owners and tenants benefit from a quick visual improvement and long-term protection of the building.
Conclusion
The use of drones in the maintenance of facades and roofs is not just a gimmick innovation. It is a genuine technical and operational revolution that transforms the approach to building maintenance. By combining safety, speed, efficiency, and respect for the environment, drones redefine quality standards for construction professionals and public clients. They pave the way for more sustainable, smarter, and more respectful construction practices for both people and places.

How to choose the right company to renovate a social housing project – Drone or traditional method?
How to choose the right company to renovate a social housing project – Drone or traditional method?
Renovating the facades of a social housing block is a delicate operation that involves significant costs, the safety of the workers, the comfort of the occupants, and the durability of the materials. For a long time, scaffolding has been the norm. However, the introduction of drones in the construction sector disrupts this logic. Less invasive, quicker, and more ecological: drones are becoming a high-performance alternative to traditional techniques. However, it is essential to know how to choose the right service provider.
Understanding the stakes of renovating social housing facades
An imperative to preserve the building and reduce costs
Social housing blocks, especially those built in the 1960s to 1980s, often exhibit pathologies related to humidity, urban pollution, and the porosity of materials. Without regular treatment, these buildings undergo accelerated degradation: cracks, efflorescence, moss, and lichen impair both aesthetics and the strength of the finishes. In the long run, this implies heavy, lengthy, and costly repairs.
However, a well-maintained facade can prevent these major works. A simple cleaning combined with an antifungal treatment and water-repellent protection can extend the lifespan of the envelope by 5 to 10 years.
Residents at the heart of the project
Renovating an occupied building also means meeting requirements for comfort, safety, and discretion. Residents must be able to continue living normally during the works: less noise, less dust, less inconvenience. This is a fundamental criterion when choosing a service company.
The traditional method using scaffolding – an outdated model?
A cumbersome and restrictive system
Erecting scaffolding on a multi-storey building often requires several days, or even a whole week. This involves:
Temporary obstruction of access
Relocation of vehicles
Significant noise disturbances
Increased risks of intrusion or vandalism in urban areas
In addition, there is also a complex logistics: authorizations, transport, assembly, disassembly, safety checks… all of this weighs heavily on the duration and cost of the site.
Costs that can be disproportionate
Scaffolding costs, on average, between €15 and €25 per m², depending on the height and configuration. For a building of 5,000 m², this can represent up to €100,000 just for the access structure. These costs do not cover cleaning, treatment, or painting, but only the logistical implementation.
The drone – a technology suited to the challenges of social landlords
A quick, clean, and safe solution
Thanks to a spraying drone, facades can be treated from a distance, without physical contact. This reduces:
Intervention time (from several weeks to a few days)
Risks of workplace accidents (no work at height)
Inconveniences for residents (no blocked access, less noise)
The drone also allows access to complex areas (balconies, cornices, narrow gables), often neglected during manual interventions.
Proven performance in the field
Specialized companies like FlyRenov have demonstrated their ability to treat buildings of 5 to 12 storeys within a few days, using bio-sourced products that are environmentally friendly and do not require rinsing. The effects are visible within 15 to 30 days, with protection that can last up to 5 years. This significantly reduces maintenance costs in the long term.
Criteria for choosing your social housing renovation service provider well
Certified drone expertise
Ensure that the company has:
DGAC certified pilots (Directorate General for Civil Aviation)
Specific RC Pro insurance for technical flights
A drone fleet approved for urban zones (S1, S2, S3)
Experience in social housing
It is essential that the service provider knows how to work in an inhabited environment. They must be able to:
Communicate with residents
Set up effective marking
Adapt their hours to the constraints of the site
Follow-up and transparency
A good company provides:
An initial diagnosis with photos and mapping
A product sheet of the treatments used
A post-intervention report with a condition report
The drone, a strategic and sustainable choice for landlords
The drone method does not replace all construction jobs, but it today stands out as the quickest, cleanest, and most cost-effective solution for treating social housing facades. By choosing a qualified service provider, landlords can extend the lifespan of their assets, reduce costs, and improve the daily lives of their tenants. The choice is clear: innovate to better maintain.

Other technologies such as terrestrial rovers, IoT sensors, or digital twins are also contributing to this transformation of the construction industry.
The drone, a multifunctional ally on construction sites
Inspection, diagnosis, and modelling
Drones equipped with high-definition, thermal, or multispectral cameras allow for:
Rapid and secure inspection of roofs, facades, or frameworks
Detection of defects invisible to the naked eye (thermal bridges, infiltrations, cracks)
Creation of 3D models (photogrammetry) useful to architects and engineering offices
This significantly reduces the time required for technical audits and improves the accuracy of diagnoses.
Cleaning, treatment, and maintenance
Thanks to the evolution of spraying drones, specialised companies can now:
Clean roofs or cladding without scaffolding
Apply antifungal or water-repellent treatments with unmatched precision
Operate in dangerous or hard-to-reach areas
Surfaces of several thousand square metres can be treated in a few days with reduced water consumption and near-zero carbon emissions.
A tool for productivity and safety
Reducing human risk
The drone eliminates the need to send operators to heights. It thus helps to:
Limit falls, the main cause of fatalities in the construction sector
Reduce the strain of tasks
Operate in post-disaster zones (collapses, asbestos, unstable roofs)
Time and efficiency gains
A facade diagnosis performed by drone takes a few hours instead of several days using traditional methods. This allows for:
Making decisions more quickly
Reducing the number of participants
Improving the profitability of construction sites
A response to environmental challenges
Less equipment, less fuel, less waste
By replacing scaffolding, lifts, and heavy vehicles, the drone reduces the ecological footprint of interventions. Its low energy requirement, combined with biosourced products (in the case of treatments), meets the demands of HQE, BREEAM, and RE2020 labels.
Softer interventions for residents
In the case of social housing or inhabited condominiums, the drone allows for:
Drastically reducing noise disturbances
Not blocking access to housing
Avoiding the risk of vandalism on scaffolding
It is a discreet, clean, and socially responsible solution.
The drone is not enough: towards a global technological ecosystem in construction
Rovers, exoskeletons, connected sensors
Innovation does not stop at the sky. On the ground, other tools are emerging:
Autonomous rovers for the inspection of technical galleries or underground construction sites
Exoskeletons to ease the effort of workers during repetitive tasks
IoT sensors to monitor temperature, humidity, pollution, or vibrations on a construction site in real time
These technologies do not replace human workers but assist, secure, and improve their comfort at work.
The digital twin and AI as catalysts
When combined with these tools, digital models of buildings (or "digital twins") enable:
Simulating work before it starts
Optimising logistical planning
Anticipating friction points or anomalies
Artificial intelligence (AI) will handle these data flows to aid real-time decision-making.
Tomorrow's construction will be safer, faster, and more humane
Less hardship, more control
Automating certain critical tasks (diagnosis, spraying, logistics) allows workers to refocus on high-value tasks. This transforms the relationship to the profession and enhances human skills.
A better quality of life for all
By enabling cleaner, shorter, and more respectful construction processes for residents, these technologies also contribute to improving the living conditions of occupants of renovated buildings: less disturbance, greater sustainability, better energy performance.
Conclusion
The drone is not a gadget. It is a central building block of a technological future applied to construction. Versatile, fast, secure, and ecological, it transforms the ways of designing, diagnosing, and maintaining structures. Combined with other innovations such as rovers, sensors, or AI, it prepares for a more intelligent, sustainable, and human-respecting building environment.
Investing in these technologies is building the future.
