 Re: "lead pollution"
Hi jctgf
Yes, Snowcake is correct. Lead is a poisonous heavy metal that can accumulate in the body.
It used to be used for water pipes in the UK, but was, hopefully, phased out many years ago.
Its use for roofing is based on the fact that it doesn't corrode away and is very "malleable", i.e. it comes on sheet form that can be easily molded around roof tiles. It's primarily used nowadays as "flashing", to cover difficult gaps in the roofing system that would otherwise let in the water.
