How much approx is lead flashing for the roof? I have a conservatory roof which is leaking in in a couple of places and a roofer that came to look says that the wall that joins the roof is perished and no lead has been used to seal it properly in the first place anh he said the lead is going to cost approx £500 alone, he went on to say that lead has increased a lot in price recently and it's gone up £100 a ton this month alone. I'd hate to be ripped off.
I have done a search on google but can't find a price but I don't know what sort I should be buying either as it looks like there are different types/grades.
Any advice welcome.
Thanks.
