Abstract: An improved zinc flashing system for use with metal and non-metal roof systems. The improved zinc flashing system includes a base plate that includes an aperture and vertical tube that is attached to the base plate. The vertical tube form extends upwardly from the upper surface of the base plate or downwardly from the bottom surface of the base plate. The zinc flashing system is designed to form a water-tight seal about a roof penetration and/or a roof drain. A protective layer can be used to inhibit or prevent contact of the zinc material of the zinc flashing with a roofing structure. The protective layer can be connected and/or coated to the zinc flashing.
