Mr Baldry said the number of thefts was likely to be much higher as insurance claims will only have been made if the value exceeded the excess.
He said that in 2010, metal theft cost the church around £6.5 million, of which £2.3 million was covered by the insurance, compared to £10 million last year, of which almost £4.5 million was covered.
A Church of England spokesman welcomed the government's attempts to crack down on the crime by outlawing cash payments for scrap metal and significantly increasing fines for scrap metal offences.
He said: "At least 10 churches a day are suffering from this escalating crime and the cost for parishes is enormous, not just to replace the roof but to repair the subsequent damage which often runs into the thousands of pounds."
Churches are considered soft targets due to their lack of security. Manchester Cathedral has fallen victim to so many thefts that it can no longer claim on its insurance. One of the latest incidents saw thieves actually enter the church, posing as visitors, to steal a 2ft silver cross that was chained to a shelf.
Some churches have chosen to adopt radical measures. St John the Baptist in Bromsgrove, Worcestershire, is replacing its lead with fibreglass while at St Nicholas Russian Orthodox Church in Marston, Oxfordshire, worshippers staged a sleepover to deter thieves last year.
Many are to install special motion sensors in spires and finials which will trigger a booming voice designed to surprise thieves and warn them that security guards are on their way.
Mr Baldry said: "Churches provide one of the few community meeting places left in some communities. They do not have much money and are having to divert funds from other projects.
"The Church of England still has a high proportion of grade one listed buildings which incur serious costs. The hope is that with the change in law, these figures will come down."
Mr Baldry was responding to a written question tabled in the House of Commons by Gloria De Piero, MP for Ashfield, who said Government proposals to increase fines and stop cash payments at scrap yards were not enough to help police crackdown on the crime.
"The police have been clear they require greater powers to enter scrap metal yards and close dealers not obeying the rules," she said. "The government needs to go further."
Ecclesiastical, the main Church of England insurer, has confirmed that last year was the worst on record for metal thefts from churches.
A security campaign called "Hands off Our Church Roofs" is being backed, in traditional style by an actress and a bishop: Liz Hurley and the Bishop of London, the Rt Revd Richard Chartres.
