Drone roof inspection in Saint-Nazaire

Drone roof inspection replaces scaffolding or a cherry picker at a tenth of the cost and with zero human risk. In under an hour of flight, we photograph an entire roof in high resolution: displaced or cracked tiles, missing slates, damaged ridge lines, punctured zinc work, moss, blocked gutters, faulty flashing around chimneys. Optical zoom detects defects invisible from the ground, down to cracks of a few millimetres.

You receive a photographic report organised by zone (slopes, valleys, verges, singular points) with the location of each defect and full-resolution images. This document supports your roofer's quotation, an insurance claim after storm or hail, or a pre-purchase survey. Co-owned buildings, social landlords, churches and listed buildings: we work at any height.

Common use cases

The local context in Saint-Nazaire

Saint-Nazaire is one of France's great maritime-industrial cities: Chantiers de l'Atlantique builds the world's largest cruise ships here, Airbus Atlantic assembles aircraft sections, and the Nantes-Saint-Nazaire seaport stretches to Montoir. Direct consequence for drone pilots: these industrial and port areas are no-fly zones, as is the WWII submarine base, and Saint-Nazaire-Montoir aerodrome (LFRZ) adds its own constraints to the north-east.

Outside sensitive zones, the city offers the Saint-Nazaire bridge (3,356 m over the estuary), the rebuilt seafront, beaches and the coastal path towards Pornichet. The local drone market is heavily industry-driven: monitoring of shipyard and offshore-wind projects (the Saint-Nazaire wind farm was France's first), structural inspections, thermal surveys of industrial roofs — missions that almost always require access protocols negotiated with site operators.

Applicable regulations

Roof inspection is flown at low height directly above the building, most often in sub-category A1 with a sub-250 g drone or in A2 with a class C2 drone when sensor resolution demands it. In built-up areas, commercial flights are conducted either in the open category over public space (allowed for professionals since 1 January 2026, no overflight of people, daytime only) or under the STS-01 scenario with a prefectural declaration. The pilot keeps clear of uninvolved persons: the ground area under the drone is secured during the flight. Operator registration on AlphaTango is mandatory, height is in any case far below the 120 m ceiling, and nearby restricted zones (hospital helipads, airfields) are checked on the Géoportail map.

Frequently asked questions

Is the inspection report valid for my insurance?

Yes: the dated, geolocated photographic report is accepted by insurers as evidence after a loss. For adversarial expert value, it can be supplemented by a building surveyor's visit.

Can you inspect a very steep roof or a bell tower?

That is exactly the drone's strength: steep slopes, bell towers, spires and towers are inspected without ropes or scaffolding, with images taken a few metres from the surface thanks to obstacle-avoidance sensors.

How long does a roof inspection take?

For a detached house, 30 to 45 minutes on site is enough. An industrial roof or a co-owned building takes 1 to 3 hours. The report is delivered within 48 hours.

Can this service be flown anywhere in Saint-Nazaire?

Almost: Zones interdites des Chantiers de l'Atlantique et du port de Montoir; Aérodrome de Saint-Nazaire-Montoir (LFRZ); Base sous-marine et installations portuaires sensibles. Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
