Portsmouth Crown Court heard on Wednesday that In June 2018, the Chippenham resident was cold-called by two men who said they were in the area cleaning gutters and offered to carry out similar work on his property.
He was told the work would cost about £4,500.
Once it began however, the homeowner was tod the work needed was considerably more extensive and could end up costing between £100,000-£150,000.
In total, he was charged £148,000.
Once works began, the victim was informed that the work required was considerably more extensive than he had originally been quoted for and would cost between £100,000-£150,000.
He was charged £148,000 in total.
The victim was then told that damp had been discovered in his loft, requiring further work.
Over the next three months, he wrote cheques totalling £406,975 to Pridenorth Limited, of which Mr Ball, from Essex, is the sole company director.
In January 2021, the victim was visited by a man claiming to be the head of Trading Standards, who claimed they were investigating the rogue traders.
The man then went to his bank, where staff realised he had been a victim of fraud.
A surveyor engaged by Wiltshire Council worked out the man’s roof did not need to be replaced, but if it had been, it should have cost in the region of £4,000.
In December 2023, Romashyn from London, was found guilty of laundering £19,700 associated with the work.
Ball admitted laundering the full £406,000 contrary to the Proceeds of Crime Act 2002
