Warning over rogue roof workmen in Nottinghamshire
The number of complaints about poor roofing work in Nottinghamshire rose sharply from 2009 to 2010, trading standards officials have said.
Substandard roofing work was the subject of 218 complaints in 2010, compared to 117 in 2009.
One elderly couple in Stapleford were charged £8,000 for two days of roof repairs, but refused to pay, a trading standards spokesman said.
The men did the work without permission from the couple and demanded cash.
Nottinghamshire county councillor Mick Murphy said: "Anyone who agrees to a contract like this should be given a seven-day cooling off period but many companies prey on the elderly and try to rush them into doing the work by offering a dubious 'discount'.
"I would urge anyone who does need work to their home or garden to use the Buy with Confidence scheme which only lists businesses which have been vetted by our trading standards team."
The daughter of the elderly couple, who did not want to be identified, said: "They didn't want these people here - mother is registered blind and stepfather has problems with his sight.
"These people are a threat and they caused hours and hours of stress to my parents.
"After two days of work they said 'that will be £8,000' - and four of them surrounded my father in the garden and said 'we want £8,000 cash'."
The couple contacted the police and trading standards but the workmen did not return to the property.
