Just wondered if anyone had got the lead flashing replaced by their dorma window. I’m in a terraced house about 120 years old with a slate roof. Getting a quote this week but wanted to ask if anyone had a rough idea of cost of replacement. It is causing a gap in the slate tiles causing water to get in. Hoping it isn’t too expensive to fix. It’s less than a metre length that needs replaced - as far as I know. I’m in Scotland if that makes a difference. Many thanks
