Zinc roofing has become more and more popular because it is durable, environmentally friendly, needs little maintenance and has a distinctive sheen. Zinc has the ability to remain corrosion-free for 25 years before corroding slowly (whereas other metals simply begin to rust). And unlike nearly all other roofing materials (except copper, in this respect), when it does start developing a fine white oxide layer the zinc will heal itself over time in a way that makes millet roof look really quite new. Zinc is thus an excellent choice for people who want their investment in roofing to last – especially considering what an outstanding job it does even on sunny days
What is zinc roofing?
Zinc roofing is a type of metal roofing that is long-lasting, sustainable, and readily shaped into unique designs.

Zinc roofing details:
Zinc roofing consists of zinc panels or shingles laid over to provide protection for buildings. Its special features include developing patina over time, which adds to its rust and corrosion-resistant properties. Zinc is a soft and malleable material; hence, it can easily be molded into various shapes and designs suitable for modern architectural projects. It is also lightweight, therefore putting less weight on the building structure, and requires less support material in installing compared to heavier roofing systems.
