£3,500 and no work done: the offer to help that’s really a roofing scam - 世界杯赛程

Citizens Advice warns of its No 1 scam as growing number of people are targeted by criminals posing as roofers

The builder who calls at your door says they are doing some work in the area and has spotted a loose tile on your roof. They offer to fix it for a good price that you agree to.

But when they go up on their ladder to inspect the problem, they see another problem. Rain has been splashing out of the gutters and the wood around them is getting damaged. The only solution, the builder says, is to have rigid PVC trays installed to divert the water.
