Theft of Metals - an escalating problem - abbreviated version

by Rowena14. October 2013 10:56

   Wherever metals are present there is an increased risk of theft and existing security arrangements should be reviewed.


   The following can be used as a checklist when reviewing security for your premises. Some are largely common sense low-cost options, whilst others involve the use of more high-tech solutions at a greater cost. Risk factors will vary for each property under consideration and some security measures will be more appropriate than others for a given premises. We have started with the lowest cost options:

  • Make theft more difficult by removing any easy access onto building roofs, such as water butts, waste bins and tall trees located near to the building. Remember to get any necessary approval for tree cutting, e.g. from the local authority, before work starts.
  • Store ladders in a secure place. This is particularly important when building works involving the use of scaffolding are taking place. Your Insurer must be advised in advance of any building work being undertaken. Non-disclosure of this material fact could affect your insurance cover.
  •  Keep any gates locked and restrict vehicular access to the site. Remove any easy means of transporting stolen goods, such as wheelbarrows and wheelie bins, to a secure place.
  •  Maximise surveillance levels, including cutting back tall trees and vegetation which could otherwise provide a screen to hide criminal activities. Remember to get any necessary approval for tree cutting, e.g. from the local authority, before work starts.
  •  Carry out regular checks of roofs so any theft of roofing materials is discovered before it rains and water enters the building causing further damage.
  • Encourage members of the local community to keep a vigilant eye on the building and to report any suspicious activity, particularly the unexpected arrival of workmen at the property, immediately to the police. Ask your local Police Community Support Officers to include the buildings on their patrols.
  •  Apply anti-climb paint to drain pipes and roof guttering to restrict access to roofing. The paint should not be applied below a height of 2 metres and warning notices, highlighting its use, should be prominently displayed.
  • Protect the lower section of lightning conductor ribbons using a metal cage or sheath securely fixed to the building fabric.
  • Consider installing security lighting, particularly at roof level where metal roof coverings are present. Check if consent is needed to do this with your local authority.
  • Security mark metal goods; eg SmartWater.  Where security marking is to be applied on roofs, appropriate safety precautions identified from risk assessment should be followed.
  • Consider installing a Closed Circuit Television (CCTV) system with adequate monitoring and recording, and display prominent warning notices around the site.
  • Consider installing intruder alarm protection to external roof areas, and any scaffolding, using equipment designed to operate efficiently outside.

   Alarm signalling should be automatic to an alarm receiving centre, or directed to the telephone of appointed key holders. Audible only signalling may be acceptable in areas where a reasonable level of surveillance can be expected. Key holders should be briefed on what to do in the event of an alarm activation by your local Crime Prevention Officer.

   Alarm systems should be installed and maintained by an NSI or SSAIB approved company. To find details of approved companies in your area please visit and

   When scaffolding is used, as well as intruder alarm protection, consider the following precautions:

  • Try to only erect it where it is needed for a particular phase of work
  • Corrugated iron sheeting or solid timber boarding should be bolted to the base of the scaffold to a height of 3.5 metres to deter climbers
  •  Remove ladders to a secure place at the end of each day
  •  Erect ‘Heras’ fence panels around the work site at a height of at least 2 metres
  •  Only hold enough roofing material for that day’s work on site
  • Advise the local police
  •  Ask local people to keep an eye on the property
  • The use of security patrols or manned guarding, undertaken by National Security Inspectorate (NSI) approved and licensed security personnel. For details of NSI approved companies in your area please visit

   If a theft of metal occurs, consider the environmental and conservation benefits of replacing it on a like-for-like basis, before considering a less theft-attractive material, e.g. stainless steel instead of lead.

   If alternative roof coverings are selected, Planning Permission and Listed Building Consent may be required in some circumstances, as well as approval from English Heritage and other conservation bodies. English Heritage will consider each case on its merits and is only likely to approve the use of alternative materials if effective security measures to prevent further losses cannot be achieved and/or the heritage of the building does not warrant like-for-like replacement.

   If sheet lead is put back on roofs, consider having it fixed using hollow rolled sheet rather than wood-core rolled sheet. The copper fixings used to secure hollow rolled sheet lead make it more difficult to remove.



In the event of a theft of metal loss you should immediately:

  • Notify the police, this is usually a condition of your policy cover
  • Notify your insurer, calling as soon as possible to report the loss
  • If you are insured via a broker, contact your broker straight-away

   Regardless of your insurance cover, to minimise damage to your property, contractors should be asked to carry out emergency repairs to make the roof water tight. Roofing material used for temporary repairs should provide effective weather protection for the duration of its anticipated use.

   Review security arrangements before making permanent repairs using a like-for-like material.
