Choosing points
- Best for roofs, gutters, lighting, and accent hardware where aging color is part of the design.
- Fresh copper is bright and reflective, but it rarely stays that way outdoors.
- Runoff from copper can mark adjacent stone, render, or concrete.
- The green patina is slow to develop and depends on climate and exposure.
How it ages
- Long-lived when detailed correctly. Avoid direct contact with metals that can create galvanic corrosion.
What to avoid
- Do not use copper above pale stone, concrete, plaster, or glass without planning for green or brown runoff stains.
