A local resident noticed the man carrying out the work with a lack of safety equipment on the slippery tiles and quickly took snaps of the man. A worker who was caught jet washing the roof of a home in south east London with just a rope tied around him for safety . The neighbour said: 'I couldn't believe it. He was standing on the roof with a power washer and seemed to have a rope tied around his waist. 'It looked incredibly dangerous. His boss seemed to be watching sitting on a wall opposite and seemed unfazed by it all.' A building expert, who did not want to be named, said the workman should have at least had scaffolding up at the front of the property and a much longer ladder with a harness. He said: 'You can't just stand up there with a bit of rope tied around you and think it's fine, it's not.
