Copper Gutters add a touch of beauty to your home unlike any other metal. The beauty of using copper gutters on your home may be one of the best advantages to choosing this material. In addition to their elegance, copper gutters also have an incredible longevity. If properly maintained, copper gutters can last anywhere from 50-100 years. A unique feature of copper is that it is considered a "living finish". This means that over time, the appearance of copper gutters will change to reflect their environment. While copper gutters won't rust, they will eventually turn into a light green color (similar to the Statue of Liberty) due to oxidation of the metal. Copper gutters are also going to be extremely durable - weathering extreme temperatures much better than steel gutters. You're going to have a better product that lasts longer.
The downside of copper gutters? Cost. If you're considering adding copper gutters to your home, they are truly an investment. On average, copper gutters start at around $18/length. Copper gutters also come with a complex, time consuming installation. While your copper gutters will be custom fit to your home, it often requires additional soldering or additional pieces, which can drive up the price as well.
All things considered, you get what you pay for. If it's within your budget, investing in copper gutters will be worth the price as they're going to last a lifetime. You're going to get a product that will evolve with you and your style. Don't like the patina green that the copper will oxidize to? This can easily be buffed out of the metal if you so choose.
