If it is needed, as it commonly is with chimney jobs, particularly on two-storey homes, then the cost will be around £300 to £400 more expensive, meaning a typical cost to replace the lead flashing on a chimney will be around £800. The price for replacing all four sides of flashing (the apron, step flashing and back box) is around £400 to £500 for the materials and the labour - however, this is the cost if no scaffolding is involved. Good lead flashing will last for decades, but if it is badly fixed or too thin, it can come loose or crack and lead to larger problems. The lead flashing around a chimney helps protect the overall roof structure from the effects of the elements, keeping rain out of the vulnerable part of the roof where the chimney meets the tiles.
