Lead, coated on one or both sides of copper sheeting, helps to further shield the roofing from weathering. Lead is also very malleable, allowing it to be formed into complex shapes at relatively low temperatures. Even on the job site, lead can be easily manipulated by skilled workers using only simple hand tools.

Is lead coated copper still available?

Lead coated copper has been used for over a century in architectural building products, and is still available. It is made from sheets of copper which are dipped into molten lead. This process completely coats both sides of the copper giving it a silver gray finish.

What is the advantage of a copper roof?

Durability

Copper resists fire, hail, mildew, and high winds. It withstands periods of freeze and thaw, oxidizes beautifully rather than rusting, and is easy to maintain. A little-considered aspect of durability is the weight of the roofing material. Though metal, copper is actually a lightweight roofing material.
