However, you may not be very familiar with this durable roofing material. Using this guide, you will understand the benefits of copper roofing and learn how to properly clean and enhance it.

The 411 on Copper Roofing

You most likely are in love with the look of your copper roof. The unique color and sleek texture enhance the architectural style of most homes, creating an appeal that will remain classic for many years to come.

Although its visual appeal is a main benefit of copper, its intense durability is what makes it such a great option for your home's roof. With proper cleaning and care, your copper roof can last up to 100 years.


Light dirt, dust, leaves, and straw may accumulate on your roof, so a periodic cleaning will be necessary. Without removing this debris, your copper may discolor and stain, reducing its classic appeal. Fortunately, cleaning your copper roof is a simple process. To get started, rinse off your roof using a garden hose. This is sufficient for removing any debris on your roof. Then, add the following ingredients to an outdoor sprayer:

  • 2 gallons of white vinegar
  • 2 cups of pure lemon juice
  • ¼ cup of table salt

Shake the container to mix the ingredients before spraying the solution on areas of your copper that appear dirty or lightly stained. Use a soft-bristled brush to scrub the solution over the stained area of your copper before rinsing with your garden hose.

If parts of your copper roof appear heavily soiled from oxidation due to weathering, create a copper-polishing paste using the following ingredients:

  • 2 cups of white vinegar
  • 2 tablespoons of flour
  • 1 tablespoon of table salt

Mix in a bowl and apply the paste to a microfiber cloth. Use circular motions to rub the paste into the stained areas on your copper roof. Allow it to sit for a few minutes before wiping away with a damp cloth.


Copper will change from its natural color, which is similar to a shiny penny, to a greenish tone. Known as a copper patina, this greenish tint can take up to 20 years to develop in a dry climate. Of course, you may not want to wait this length of time to enjoy the natural appeal of copper's patina. Fortunately, you can accelerate the patina process. Visit your local home improvement store to purchase an already-mixed artificial patina solution or create your own by following the instructions below.

To age your copper artificially, line a large corrosion-resistant bucket with plastic and pour in 6.5 gallons of tap water. Pour in 6 pounds of ammonium sulfate and allow it to dissolve into the water. Add 3 ounces of copper sulfate and 1.3 fluid ounces of concentrated ammonia to the container, as well.

Pour the mixture into an outdoor sprayer and spray a thin layer on your copper roof. Be sure to spray in an even manner across the roof, since an uneven amount may cause streaks to run down the roof. Allow the solution to soak and dry.

You will not immediately see a change in the color of your copper after applying the aging solution. However, the color should begin to change after a few days or weeks, depending on your local climate.

Copper roofs are appealing, valuable, and durable options for homes, but proper cleaning and care is necessary.
