Roof inspection after a storm: the drone for your insurance claim
Tiles blown off, ridge displaced, damp patch on the ceiling: after a storm you need to assess the damage, prove it to your insurer, and above all not climb onto a weakened roof. A drone inspection answers all three needs in a single visit. Here is how to use it to build a solid insurance claim, on time.
Insurance deadlines: five working days to declare
The first urgency after the storm: declaring the claim. For a weather event covered by the storm guarantee of your French home insurance policy, the usual contractual deadline is five working days from discovery of the damage. If the event is recognised as a natural disaster by interministerial order (which does not apply to wind, but to the floods or mudslides that sometimes accompany it), the deadline is 30 days after publication in the official journal. Declare quickly, even incompletely: a summary declaration within the deadline, completed later by the detailed report, always beats a perfect file submitted late.
Second reflex: protective measures. You have the right — indeed the duty — to limit further damage: tarpaulins, gathering fallen tiles, moving belongings to safety. However, do not undertake permanent repairs before the loss adjuster's visit or the insurer's written agreement, and keep every invoice (emergency tarping included: it is generally reimbursable). Above all, photograph everything, before and after tarping. That is exactly where the drone comes in.
Why a drone rather than a ladder
Every storm season brings its share of injuries to people who climbed up "just to check" the roof: after a gale, a roof covering is by definition weakened — loosened tiles, broken battens, deformed flashing — and slippery. The drone removes that risk: it inspects the entire roof from the ground, in 30 to 60 minutes, touching nothing and putting no load on the structure. No scaffolding, no cherry picker, no impact on an already weakened covering.
The other decisive advantage is completeness. From the ground or a window you see one slope, and only partially; the drone photographs all four slopes, the ridge, the valleys, the chimney flashing, the verges and the gutters, in wide views and close-ups thanks to the zoom. After a storm, the most insidious damage is invisible from below: tiles shifted by a few centimetres (water will get in at the next rain), cracked ridge tiles, localised membrane tears on flat roofs. A complementary thermal inspection can even reveal water ingress already active under the covering, invisible to the naked eye — a point detailed in our comparison roof inspection: drone or cherry picker.
A report that carries weight with the insurer
What the insurer and its loss adjuster expect are not three blurry smartphone photos, but dated, located and interpretable evidence. A professional drone inspection report provides exactly that: high-definition photos whose metadata (EXIF) carries the date, time and GPS coordinates; wide views that place each defect on the roof; close-ups showing its exact nature; and annotated presentation — damaged areas marked on a roof plan, a description of each defect, a severity level. This document does not replace the insurance expertise, but it usefully precedes it: it freezes the roof's condition at a certain date, close to the event.
This is a crucial point: between the storm and the adjuster's visit, several weeks often pass during mass-claim periods. Without a dated record, the insurer can dispute attribution ("this damage is older — poor maintenance"). With a report produced in the days following the event, that debate is closed. The report then serves as the basis for pricing: your roofer uses the images to draw up an accurate quote without waiting, and the adjuster can cross-check their findings against yours.
Price and lead times of a post-storm inspection
Observed 2026 prices for a post-storm drone roof inspection:
| Service | Indicative price (incl. VAT) | Delivery time |
|---|---|---|
| Visual check (annotated raw photos) | €150 – €300 | 24 – 48 h |
| Full inspection with annotated report | €300 – €450 | 3 – 5 days (72 h express) |
| Inspection with thermography (tracing water ingress) | €450 – €800 | 5 – 10 days |
| Large roof (co-owned, agricultural or industrial building) | on quote, from €500 | depends on area |
On lead times, one regulatory point works in your favour: for a detached house, the pilot takes off from your land and flies over your property — a mission doable within a few days, weather permitting. In a dense town centre, if the flight must extend over public space, a préfecture declaration with 10 working days' notice may be added; professionals know this and plan the mission to avoid it whenever possible. After a major storm, pilots' schedules fill up fast: book within the first 48 hours. To find an operator near you, see our drone roof inspection page.
After the storm, beware of door-to-door canvassers
Every storm triggers a wave of door-to-door canvassing: self-proclaimed roofers comb the affected neighbourhoods, "spot" damage from the street, offer immediate repairs and get inflated quotes signed — when they do not cause damage themselves by climbing onto the roof. Trade federations and insurers repeat it after every event: sign nothing under pressure, pay no deposit to a tradesperson you did not choose yourself, and distrust anyone claiming "the insurance will pay for everything".
The drone inspection is a precious objectivity tool here, on one condition: the person recording the damage must not be the one selling the repair. An independent drone pilot has no interest in exaggerating the defects — their report commits them only to the facts observed. You then pass it to your insurer and to the roofers of your choice, who price the work on identical, comparable grounds. This decoupling of assessment and repair, standard practice in industry, protects the homeowner twice over: against under-assessment by the insurer, and against over-pricing by an opportunistic repairer.
Frequently asked questions after a storm
Will the insurance reimburse the drone inspection? There is no dedicated cover, but costs incurred to assess and limit the damage can be included in the claim, like emergency tarping. Get your insurer's written agreement before the visit, or include the inspection cost in the claim with its invoice.
Are my own hobby-drone photos enough? They are better than nothing and can supplement the file. But a leisure flight in a residential area is tightly regulated, and unmethodical images (missing angles, no overview, botched exposure) leave gaps the insurer can exploit. The professional report, exhaustive and dated, remains the reference.
How quickly can a pilot intervene? Outside exceptional surges, 2 to 5 days for a detached house whose plot can be overflown from the garden. Add the 10-working-day préfecture notice only if the flight must extend over public space in a built-up area.
Should you inspect even without visible damage? After a violent storm, yes: the costliest defects (shifted tiles, locally torn waterproofing) are precisely the ones you cannot see from the ground, and they only reveal themselves at the first heavy rain — after the declaration deadline has passed.
