Storm-Damaged TV Aerial: What to Do (and Who Pays)

If a storm has damaged your TV aerial, stay off ladders and away from anything dangling — a hanging aerial is a falling hazard and a job for a professional. Most storm damage is misalignment or a rotated mast rather than destruction, and a realignment or re-secure is a routine repair. Buildings insurance usually covers aerials as part of the structure, but the excess often exceeds the repair cost, so check before claiming. In rented homes the aerial is normally the landlord’s responsibility.

Safety first — genuinely

Two rules before anything else:

If the aerial is hanging, dangling or swinging, keep people away from below it. A UHF aerial with a metre of mast attached weighs enough to cause serious injury falling from a two-storey roof, and it rarely falls straight down — wind takes it sideways. If it’s hanging over a pavement, footpath or a neighbour’s property, treat it as urgent: cordon off what you can and call an installer the same day. If it’s tangled in overhead power lines, don’t touch anything — call your electricity network operator on 105.

Don’t go up a ladder in wind, and preferably don’t go up at all. The gusts that moved the aerial are usually still around the day after the storm. Professional installers work with roof ladders, proper anchoring, and the judgement to postpone in bad conditions; the annual toll of DIY ladder falls in the UK is grim enough that the Health and Safety Executive publishes warnings about exactly this scenario. A day or two without TV is not worth a fall.

Everything diagnostic below can be done from the ground with your eyes, or from inside with the TV remote.

Is it storm damage, or coincidence?

TV faults that show up after a storm aren’t always caused by it — sometimes a cable that had been corroding for years finally gives up on a windy night, and sometimes the transmitter itself was off-air for storm-related engineering work. Before assuming your hardware took the hit, check whether neighbours on the same transmitter — Winter Hill, Emley Moor, Mendip, Belmont or whichever serves your area — have also lost channels. If the whole street is out, it’s the transmitter, and it’ll come back on its own. Our guide to a disappeared Freeview signal covers that diagnosis in full.

If it’s just you, look up from the ground and compare your aerial with the neighbours’:

Misalignment — the aerial points a different way from every other aerial nearby. Even a 20–30° rotation can drop enough signal to lose whole multiplexes (MUXes — bundles of channels sharing one frequency), which is why storm damage often shows up as some channels missing rather than a blank screen.
Rotated mast — the aerial looks intact but the whole pole has twisted in its clamps. Same symptom, slightly bigger fix, because the clamps have lost their grip and need re-torquing or replacing.
Snapped lashing wire — chimney-mounted aerials are held by a lashing kit (a steel wire tensioned around the chimney with a corner bracket). If the wire snaps or the bracket pulls out, the whole assembly leans or swings. This is the “dangling aerial” scenario and the most urgent.
Bent or missing elements — the short cross-pieces along the aerial boom. A few bent elements degrade performance modestly; a snapped boom or missing reflector (the grid at the back) usually means replacement over repair.
Water ingress after driven rain — storms push rain horizontally into places it never normally reaches: cracked cable outer sheath, a perished connection box on the aerial, an old wall entry point. Water in coaxial cable corrodes the copper and the symptom is often reception that worsens gradually over the days after the storm, or comes and goes with the weather.

Who pays: home insurance

TV aerials fixed to the building are normally covered under the buildings section of a home insurance policy, and storm damage is one of the standard insured perils. Most insurers define a storm by wind speed thresholds (commonly gusts around 47+ mph); a named storm passing through comfortably qualifies.

Whether claiming is worth it is a different question. Work through it in this order:

Get a repair quote first. A realignment or re-secure typically runs around £80–£150; a full replacement installation around £150–£250. Our aerial repair cost guide breaks the ranges down.
Check your excess. Many buildings policies carry a £100–£350 excess. If the excess meets or exceeds the repair quote — which it very often does for aerial work — a claim gains you nothing.
Weigh the premium effect. Even small claims can nudge future premiums and count against no-claims records on some policies.

The realistic summary: insurance matters when the storm damage extends beyond the aerial — mast through a roof tile, damaged chimney, aerial fallen onto a car or conservatory. For an aerial alone, most households are better off simply paying for the repair. If the falling aerial damaged a neighbour’s property, that’s typically a claim under your policy’s liability section — tell your insurer either way.

Who pays: landlord vs tenant

In rented property, an aerial that came with the tenancy is part of the equipment the landlord supplied, and keeping it in working order sits on the landlord’s side of the ledger — storm damage is nobody’s misuse, so there’s no basis for charging the tenant. Report it in writing, keep the reply, and give reasonable time for a repair. The full picture, including communal systems in flats, is in are TV aerials a landlord’s responsibility.

Temporary fixes while you wait

If a repair is a few days away, you can usually get some TV back without touching the roof:

An indoor aerial near a window facing the transmitter will often pull in the main channels in decent-signal areas — a £15 stopgap, not a solution.
Streaming apps or Freely cover the main broadcasters over broadband. All the aerial-free routes are in can you watch TV without an aerial.
Don’t be tempted to “just push the mast back round” from a bedroom window or flat roof, and don’t put a booster on a storm-damaged aerial — an amplifier can’t recover a signal that isn’t reaching the aerial cleanly, as signal booster vs amplifier explains.

How installers put it right

A professional storm repair is usually quick, and it’s worth knowing what a good job looks like:

Realignment with a meter. The installer re-points the aerial using a signal meter reading actual strength and error rate — not by eyeballing the neighbours’ aerials — then re-torques the clamps.
A new lashing kit where the wire snapped: fresh galvanised wire, new corner brackets, tensioned properly around the chimney. Reusing a stretched wire is a bodge.
A cranked mast or repositioning where the original mounting was the weakness — for example moving off a crumbling chimney onto a gable-end bracket with a cranked (offset-bent) mast to clear the roofline.
Sealed connections. Any junction exposed to weather gets a self-amalgamating tape or gel-filled seal so the next bout of driven rain stays out of the cable.

Preventing the next one

Aerials don’t blow over at random — storms find the weak point that was already there. The main culprits: corroded ten-year-old lashing wire, oversized “high-gain” aerials on slender masts (more surface area for the wind to push against than the mounting was rated for), and rusted clamp bolts that had lost their grip. When replacing, a correctly sized aerial for your signal area — see what TV aerial do I need — on a properly rated bracket will ride out named storms that flatten oversized bargains. A quick visual check of mast, bracket and wire each autumn costs nothing.

If a storm has left your aerial leaning, dangling or dead, send us your postcode and a line about what you can see from the ground. We route enquiries to local installers who handle aerial repairs and replacements — and who will tell you plainly whether it’s a £100 re-secure or a job that genuinely needs a new installation.
