Using McMaster-Carr as a benchmark, lead sheet is a bit more expensive than the same size and thickness of 316 stainless sheet. One of these is extremely toxic and the other is pretty much harmless. (Also, 316 stainless won’t magically corrode if there’s condensation on it, and the Internet suggests this is a problem with lead.)
Sure, lead can be molded into place with traditional techniques if you can find a competent roofer with a sufficiently minimal desire for self-preservation. But modern standing seam roofs work pretty well.
