Is the property in a local historic district? If so, you may need to get
approval for material changes. The Secretary of the Interior's standards
for the treatment of historic properties generally require replacement "in
kind" when the same materials are still available. Sheet lead is still
specified in roofing preservation projects, particularly within an 80 mile
radius of Boston.
If there is no local historic commission with oversight responsibility
then you're free to do as you please. One may argue, however, that you
have an ethical responsibility to preserve the existing details or, if
restoring, replace in kind. Otherwise you risk compromising the integrity
of the roof system.

Lead-coated copper (LCC) is stocked by Erie Materials in Albany and
Newcastle Building Products in White Plains. Cambridge Street Metal's
Chicopee branch delivers to the Hudson Valley and NYC weekly. They stock
LCC and sheet lead. If you're concerned about the lead, Revere Copper
Products (near Utica) makes a tin-zinc alloy coated copper called Freedom
Gray. Their link follows.

Look up a company called Lamb and Ritchie in Saugus MA. they make about as much lead coated copper as anyone in the world. Right next door to New York too. Are the gutters built-in or the old half round? If built-in, you would want some sheet stock to work with. If half round, call my brother at Classic Gutters in Kalamazoo, Michigan and they can give you pricing on long lengths of gutter and accesories.

I am working on a grant application for the restoration of an amazing historic home in the Hudson Valley- Chris from Short Slate came and gave me some much needed analysis of it- Good man and a terrific crew!
This building is a local granite and Indiana limestone facade with a graduated Vermont slate roof. It was owned by Jacob Ruppert, owner of the Yankees and Knickerbocker Beer. Babe Ruth signed on to the Yankees on the table still there in the house. There are German mantlepieces and cast-iron fire place details from the 1600s.
Like the copper valleys, the gutters (presumably copper) are shot through with holes. The gutters and leaders, as well as the rain boxes and straps, were inexplicably painted. But close observation and some scratching showed that the straps and rain boxes are thick lead, and in very good shape.
I assume that the paint was applied to make the gutters, rain boxes, and straps match, and maybe to eek out a few more years from the pitted gutters. I am thinking that replacing the gutters and leaders in lead coated copper would eliminate the concern of color-matching, and would greatly extend the life of the new gutters. The dull light grey of the lead would fit the color scheme of the grey/black granite and buff limestone.
The question: Is lead coated copper still available in NY State? Is there a concern with lead contamination of ground water?
