Believe it or not...lead was used in the middle ages and early Renaissance as roofing material for Gothic cathedrals.

If its good enough for those magnificent Houses of God, then it’s good enough for me.

My great grandfather's house in Wales had a slate roof. It was held in place with bars of lead affixed to a framework. The lead mines were a source of employment for small Welsh boys between ages 4 and 11. After that time, they grew too big at adolescence to fit in the mines. The older boys tended sheep.

There is a Welsh variant of the Italian calzone that includes a bread "handle". The miners handled only that "handle" when eating the stew stuffed bread, then tossed away the "handle". Even then they were quite aware of the consequence of consuming lead.
