Did you just splurge on copper gutters for your home?  Good choice!  Now you’ve got these top of the line beauties shedding water from your roof, you’re probably wondering how long before they turn to that lovely, rustic green patina.

The answer to that is…. It all depends. The Statue of Liberty didn’t turn green overnight, but there are factors involved in the oxidation process.

Copper turns green through a process called oxidation. When copper is left exposed to water and air a thin layer of a green substance forms on its surface. This substance is known as copper carbonate. The oxidation of copper does not weaken it unlike iron which weakens when it rusts. Some speculate the build-up of copper carbonate actually protects the metal. Oxidation takes time. It is a gradual process and copper may turn black or dark brown before any sign of green appears. The thin layers of green are often referred to as patina.

Factors That Affect Copper Patina Process:

  • Moisture and Humidity
  • Original condition of the copper. Should be installed with gloves to prevent oils on your gutter.
  • Nitrate levels and pollutants in the rain and atmosphere. The higher the better in this case!
  • Typically patina forms on gutters before downspouts due to their horizontal position.
  • Where you live.

A copper gutter project is going to be significantly more expensive than an aluminum or steel project because of the difficulty of the install.  But when properly installed, few things will add “pizzazz” to an exterior like they do.

Copper gutters aren’t something you just buy off the shelf – they require particular expertise of a professional that is familiar with this system to measure and install them properly. Installing copper gutters can be tricky, because the lengths of copper will need to be soldered together for a snug fit.   Some people prefer to leave installation to professionals who are experienced at copper gutter installation, because mistakes with copper can get very expensive.
