Discovering that someone has stripped the lead from your roof is a nasty shock. There is the loss itself, then the worry that rain will come in before it can be fixed, then the question of whether insurance will pay. Lead flashings, valleys, bay roofs and church roofs have all been targets, because lead is heavy, easy to cut with simple tools and sells as scrap. Some houses are more exposed than others, and some simple steps make a theft less likely. This page walks through prevention, what to do straight after a theft, how insurers generally approach it and how the repair is done.
Why lead gets stolen
The motive is the scrap value. Lead sheet is dense and a few square metres weigh a surprising amount, so a thief who strips a flat bay roof or a long flashing can carry off something worth selling. Lead is also easy to cut and roll with a knife. The roofs that attract attention tend to share features: lead that is visible from the road or a lane, a roof that is easy to reach from a flat extension, garage or scaffold, an empty or unoccupied building, and a property with poor lighting at the back. Churches, schools, empty homes and houses being renovated have all been hit.
The damage can exceed the metal's value. When lead is torn from a roof, the deck beneath is often exposed to rain, and ceilings, insulation and timbers can be damaged within days. A theft of a few hundred pounds of lead can lead to repair costs many times that, which is why speed matters afterwards.
Prevention: making your roof a harder target
No measure is certain, but several reduce the odds and slow a thief down.
- Remove the means of access. Keep ladders and scaffold poles out of sight and locked away. Fit anti-climb paint, where it is lawful and signed, on drainpipes and walls that offer a route up to a lower roof.
- Light and visibility. Security lights with movement sensors at the back and sides, and keeping hedges trimmed so the roof can be seen from the street or a neighbour's window.
- Alarm or camera. A visible camera or alarm near vulnerable roofs deters opportunists. Check with the ICO's guidance if a camera views beyond your boundary.
- Mark the lead. Forensic marking solutions or stamped identifiers make stolen lead traceable and are a deterrent when signs say they are used.
- Fix the lead properly. Lead that is well-secured, clipped and bonded into masonry takes longer to remove than loose sheet.
- Tell the neighbours. A neighbour who knows you are away and who to ring is more effective than most hardware.
For empty buildings, regular visits and a keyholder who checks the roof matter. Council and police crime-prevention officers can advise on the area, and the police pages at gov.uk explain how to report an incident.
Particular risks: empty, rented and communal buildings
Some buildings are exposed in ways their owners do not always see. A house standing empty between a sale and a move, or during a long renovation, has nobody noticing a ladder at the side. A rented property may have a landlord who visits rarely and a tenant who does not look at the roof. A block of flats or a shared parade of terraces can have lead on a roof that belongs to everyone and is checked by no one. In each case the answer is a named person who looks: a keyholder, a managing agent or a neighbour with a number to ring, plus a regular glance at the roof edge after a windy night. Who pays for the repair on a shared roof is a different question, which our answer on repairs to a shared roof covers.
Substituting the metal
If lead has been stolen once, it is likely to be targeted again. Replacing it with a lower-value material takes away the incentive. Options include aluminium, zinc, EPDM on flat roofs, self-adhesive strip for hidden details and polymer lead substitutes. They are not equals: each has strengths and drawbacks that we set out in our guide to lead alternatives. On a period property or a listed building, replacement in a different metal may need consent, so ask the council's conservation team before you change the material, and note that an insurer may require a like-for-like replacement or agree to an alternative.
What to do when you find it gone
- Keep yourself safe. Do not climb on the roof or go into the loft if you suspect the structure is unsafe. If you disturb thieves, do not confront them; call the police.
- Report it. Ring the police and get a crime reference number. Insurers nearly always ask for it. Photograph the scene from the ground, noting the date, and any damage inside.
- Limit the water damage. If rain is forecast and the deck is open, the roof needs covering quickly. Move belongings, put buckets under drips and switch off the lights if water is near wiring. Our page on temporary roof repairs explains what a temporary cover involves, and when you ring us about an open roof, an emergency call comes ahead of routine bookings, with the first job being to make the roof safe.
- Tell your insurer. Do this early. Ask what they require before work begins.
- Get a proper survey. Before a permanent repair, someone needs to look at the deck, the timbers and the surrounding tiles for hidden damage.
How insurance usually treats lead theft
Buildings insurance policies commonly cover theft of fixtures and damage caused during a theft, but the detail varies a great deal from policy to policy. Some policies exclude unoccupied properties after a set number of days. Some limit cover for lead or metal theft, or apply a higher excess. Some require security measures to be in place. A policy on a listed building or a church usually has its own terms. The only way to know is to read the wording or phone your insurer.
Three points tend to matter. First, the crime reference number, which proves a theft occurred. Second, evidence of the roof's condition before and after: photographs, an earlier survey or an invoice for the lead. Third, a prompt report, since delay can reduce a claim. Our answer on claiming on house insurance for a leaking roof covers how insurers separate sudden damage from wear and tear, which applies here as well.
A surveyor's report or a roofer's written quote helps with the claim. We provide a photographed survey of your roof and a fixed written quote for the repair, which you can send to your insurer. We do not deal with claims for you, and what an insurer pays is its decision.
Putting the roof right
Replacing stolen lead is not just a matter of laying new sheet. The deck beneath may be wet or rotten, the flashings next to the stolen lead may have been disturbed, and the thieves may have cut or damaged tiles. A proper repair starts with drying and checking the deck, replacing any timber that has been wet, and re-laying in the correct code and lengths. Our guides on lead codes and lead bay roofs set out the details. The work is slower than a patch, but a patch over damaged timber fails quickly.
| Situation | Sensible step |
|---|---|
| Lead gone, rain forecast, deck exposed | Temporary cover first, then survey |
| Lead gone, deck dry and sound | Re-lay in lead or an alternative metal |
| Deck wet or rotten | Dry out or replace boards before any lead |
| Listed building or conservation area | Speak to the council's conservation team about materials |
| Property empty | Tell insurer, arrange keyholder checks, consider a lead-free repair |
Why speed matters after a theft
A roof without its lead may look like a small problem from the ground, and the water damage underneath is usually quick. Rain on an exposed deck soaks into the boards, then the rafters and the ceiling below. Within days, plasterboard can stain and sag, insulation can saturate, and a persistent damp patch can turn to mould. Timbers that stay wet for weeks can start to decay, and a rotten deck needs replacing before any lead goes back. So the order is: make safe, document, report, then repair properly. A temporary cover costs far less than the ceiling and timber repairs that follow if the deck is left open for a month.
It also helps to know what to avoid. Do not accept the first offer of cheap, quick repairs from someone who calls at the door the day after a theft, since opportunists know that a victim is under pressure. Check what is being proposed, ask for photographs of the deck, and make sure the quote names the lead code or the substitute material. A genuine repair will withstand questions.
An annual security check
Once a year, walk round the property and look at your roof as a thief would. Where could someone climb? Which lead is visible from the road? What is stored in the garden that could be used as a ladder? Is the light at the back working? Is the lead securely fixed, with no loose or lifted edges that make removal easier? Take dated photographs of the lead at the same time, because a record of how the roof looked is useful both for insurance and for any repair.
What it costs
The cost of a theft repair depends on the area taken and the damage below. As a guide to related figures, published UK cost guides put replacing chimney leadwork at £350 to £920, with an average near £570. Your fixed quote follows the survey, and a bay or flat roof is priced by area, deck work and lead code. A temporary cover is a separate and smaller cost.
How we help
We survey the damage, photograph it and tell you what is needed to make the roof safe and what a lasting repair involves. The quote is fixed and written, the work carries a 10-year workmanship guarantee that you hold on paper, and we say plainly whether lead or an alternative suits the roof. If you have just found a theft and water is coming in, ring 01256 213956 and say so, and we will give priority to making the roof safe. Our main lead roofing and leadwork page covers the rest of this work.
