I asked a roofer to replace some failed lead flashing that was allowing some water in. I was a bit shocked to see that they’d chased a new diagonal channel across the brickwork. The original flashing was stepped and all the neighbours have stepped flashing that sinks the lead into the natural gap between the bricks. Is this going to be effective? Should I be worried about this?
When I asked the guy why he had done this he said “We could not put the lead work back as it was before because the bricks were soft due to water leakage, the way we did the flashing ensured a more secure fitting in the long term”.
It seemed to me that he’s only going to make it worse by cutting a new diagonal channel in. Is this a cause for concern? Will it lead to more damage to the house? Does this look like a professional job?
