Answer:

Copper

Just as iron that is left unprotected in open air will corrode and form a flaky orange-red outer layer, copper that is exposed to the elements undergoes a series of chemical reactions that give the shiny metal a pale green outer layer called a patina.

The patina actually protects the copper below the surface from further corrosion, making it a good water-proofing material for roofs , doorknobs , railings , etc.
