Soaring metal prices has seen churches warned to step up vigilance against organised gangs of thieves.
High demand for copper and lead, driven by an increase in global metal prices, has seen a spike in the number of churches suffering thefts, said specialist insurer Ecclesiastical.
Criminal gangs target unprotected church buildings, often in remote rural locations, to steal lead roofs, flashing and even drain pipes.
The devastating impact on historic buildings was shown when St Edmund's Church in Downham Market was one of four churches targeted by thieves in February 2020.
Two-thirds of the lead roof was stripped off with an estimated £30,000 worth of damage caused to the Grade I listed building with water damage to the interior including to its pews and furniture.
Other churches that reported attempted thefts of lead including St George’s in Gooderstone and St Martin's in Fincham.
A month later three men were caught red-handed on the roof of Long Stratton Methodist Church attempting to steal lead.
Last year a prolific gang was jailed for a spate of thefts in Lincolnshire and beyond, with sentences totalling more than 22 years for the crimes that caused more than £2 million in damage, while another gang is currently awaiting trial.
Overall the number of thefts from Norfolk's churches has fallen since the launch of the Roof Alarm Scheme in 2017.
Scores of churches are now alarmed across the county with many having had additional security measures installed.
However, Jo Whyman, risk management director at Ecclesiastical Insurance, said while the last two years have seen a drop in claims, Covid lockdowns may have played a part in this.
“There is a risk that the continuing economic downturn in the UK and high value of scrap metal could see an increase in theft of metal from historical buildings such as churches, which is why it is vital that they take steps to protect their premises from unscrupulous offenders,” he said.
“Theft of metal can have a devastating impact on churches and heritage buildings.
“Aside from the cost of replacing the metal, further damage can happen as a result of exposure to the elements which can cost thousands of pounds.
“It is vital that churches in Norfolk take steps to protect themselves from thieves.”
