Short answer
Both are premium, low-maintenance metals that resist corrosion and can outlast the house. Copper can last up to 100 years and ages from bright copper to a golden or green patina, which suits traditional and heritage homes. Zinc lasts 70 to 90 years and stays a soft grey or black, which suits modern designs.
Copper and zinc are the two metals we’re asked about most. They have a lot in common, and the choice usually comes down to the look you want.
What they share
- Both resist corrosion and need very little maintenance.
- Both are lightweight, fire-resistant, waterproof and recyclable.
- Both suit most roof structures.
- Both can be used for a whole roof or for details: bay windows, awnings, dormer roofs, parapet flashings, eavestroughs, soffits and fascia.
- Both add lasting value to a home.
Side by side
| Copper | Zinc | |
|---|---|---|
| Lifespan | Up to 100 years | 70 to 90 years |
| How it ages | Bright copper darkens, then forms a protective golden or green patina | Coloured finishes weather slowly toward natural quartz grey |
| Finishes | Mill (bright new copper) or pre-patinated | Natural quartz zinc (grey with a hint of green), anthra zinc (black), and blue, brown or green by special order |
| Best suited to | Traditional, Victorian and heritage homes, churches | Modern and contemporary architecture |
Choosing between them
Choose copper if you want warmth and character, or you’re matching existing copper on a heritage home. The patina is part of the appeal: it protects the metal and gives the roof a look that changes over the decades. If you’d rather not wait, pre-patinated copper starts out green.
Choose zinc if you want a clean, consistent, modern look. Anthra zinc is a premium alternative to black steel or aluminium, and natural quartz zinc pairs well with stone, glass and wood.
Small touches, big impact
You don’t need a full metal roof to get the look. A copper bay window roof, entrance canopy or set of eavestroughs on an otherwise shingled or slate house is one of the most popular projects we do. See our copper and zinc finishes for examples.
