Choosing points

  • Best for calm matte metal roofs and facades that age toward a blue-gray tone.
  • Zinc has a soft, matte gray look that becomes calmer with age.
  • It scratches and marks more easily than stainless steel, but small marks often blend into the patina.
  • It is often chosen when a building needs a quiet metal surface rather than a shiny one.

How it ages

  • Zinc performs well when ventilated and allowed to dry. Trapped moisture behind sheets can cause corrosion from the underside.

What to avoid

  • Do not expose zinc to acidic runoff, water from copper, or standing water. It can stain, pit, or corrode unevenly.
