Core service · drone inspections

Every crack, every leak, every detail — captured from the air.

From residential roofs to wind turbines, factory halls and historic buildings: our pilots deliver detailed inspections with enterprise-grade drones, thermography and documented reports — without scaffolding, ladders or production stoppages.

For which sectors

One methodology, eight sectors.

From a small roof to an entire industrial site — we adapt the sensor and flight altitude, but precision stays the same.

Homes & residential
Fast roof checks after a storm, before a sale or for insurance purposes. No ladder against your façade.
Warehouses & SME roofs
Flat and pitched roofs across industrial zones — leaks, insulation, roofing and solar panels in a single flight.
Factories & industry
Chimneys, silos, cooling towers, pipe bridges and installations without disrupting production.
Wind turbines
Blade inspections with minimal downtime. Detection of erosion, delamination and lightning damage.
Real estate & syndics
Apartment buildings, office towers and façades — objective condition reports.
Heritage & religious buildings
Churches, castles and monuments. Irreplaceable imagery without a single point of contact with the structure.
Energy & networks
High-voltage pylons, transformer parks and lines in compliance with safety procedures.
Construction & sites
Progress monitoring, handover dossiers and 3D models of every phase.
The problem

What you don't see costs you the most later.

80% of roof damage starts with a problem that is invisible from the ground. By the time the ceiling leaks, the damage is ten times more expensive than timely detection. A periodic drone inspection catches that in time — for a fraction of the cost of a traditional survey.

Invisible damage
Hairline cracks, blisters and shifted tiles go unnoticed for months until they cause leaks indoors.
No view at height
Chimneys, towers and roof edges are virtually impossible to inspect without scaffolding.
Risk & cost
Working at height requires scaffolding, aerial work platforms and safety inspections — costly and time-consuming.
Incomplete records
Without dated imagery, you're in a weak position with insurers, syndics or courts.

Sensors & technology

The right sensor for every inspection.

Our drones carry interchangeable payloads. For each assignment we choose the sensor that provides the answer.

45 MP RGB
Zenmuse P1 & H30 — visible damage in ultra-high resolution, down to millimetre detail.
Thermography
Infrared camera detects heat leaks, moisture in insulation and defective cells in solar panels.
3D mapping
Photogrammetry produces a scalable 3D model with exact measurements of every detail.
LiDAR & RTK
Centimetre-precise georeferencing for volume measurements, heights and roof-surface calculations.
Thermography in action

From RGB to thermal image — in a single flight.

Our dual-sensor combines a 45MP RGB camera with a calibrated thermal module. Heat leaks, moisture in insulation and defective solar cells become visible without a second flight.

Workflow

Six steps, from intake to digital dossier.

  1. 1
    Intake & objective
    You provide us with the location, building type and reason for the inspection (purchase, insurance, maintenance, damage).
  2. 2
    Flight plan & airspace
    We check airspace, obstacles, neighbouring buildings and, if required, request authorisation from skeyes.
  3. 3
    Execution
    Certified pilot flies a fixed grid pattern — so we don't miss a single roof surface or component.
  4. 4
    Image processing
    Images are stitched, geo-referenced and, where needed, converted into an orthomosaic or 3D model.
  5. 5
    Analysis
    Our analyst marks defects, measures surfaces and categorises them by urgency.
  6. 6
    Digital report
    You receive a PDF dossier within 48h with annotations, photos, map and recommendations.

Comparison

Drone inspection vs. traditional method

Scaffolding, aerial platforms or rope access are expensive, time-consuming and risky. The drone does the same job in a fraction of the time — with better documentation.

What you receive

More than photos — a complete technical dossier.

Every inspection concludes with a structured report you can use to negotiate, insure or plan maintenance. Black and white, with photographic evidence and measurable data.

  • High-resolution photos per roof surface, façade or component
  • Thermographic imagery where relevant
  • Orthomosaic map with measurements to scale
  • Annotated defect report (urgency + recommendation)
  • Optional 3D model or digital twin
  • Fully insured and EASA-compliant execution

When to use it

Four moments where a drone inspection pays off.

Clients often recoup the investment with a single decision.

Before purchase / sale
Objective view of the roof, façade and chimney. Prevents disputes and surprises at signing.
After storm or hail
Fast damage report for your insurer — with date, GPS and detailed photos.
Periodic maintenance
Annual checks for syndics and property managers. Minor maintenance prevents major renovations.
Turbine & installation
Blade, mast and installation inspections with minimal downtime and a full report.

In practice

Wind farm, West Flanders — 3 turbines.

Annual blade inspection of three 3 MW turbines. Instead of a rope-access team and a full stop per turbine, our pilot carried out all three inspections in a single morning. Result: 6 defects detected (including 2 critical erosions at the blade root) and reduced downtime cost.

Frequently asked questions

What you often want to know before an inspection.

How long does a roof inspection take?

A typical home takes 20 to 40 minutes on site. An SME warehouse or industrial roof: 1 to 3 hours, depending on surface area and level of detail.

Do I need to shut down the building or installation?

In most cases, no. For wind turbines, a short standstill suffices (~15 min per blade). Factories and offices remain fully operational.

What if weather conditions are poor?

In case of rain, fog or wind >10 m/s, we postpone. You are notified in time and we reschedule free of charge.

Can I use the report for my insurer?

Yes. Our report includes date, GPS coordinates, high-resolution photos and, where needed, thermography — sufficient for most insurance claims and expert assessments.

Is the inspection GDPR- and privacy-compliant?

Absolutely. We adjust the flight route to avoid neighbouring plots, and imagery is kept strictly confidential within your file.

Do you work throughout Belgium?

Yes. Standard travel is included within 15 km of Geraardsbergen. Beyond that, we charge a limited mileage fee — always communicated in advance.
