How To Clean Copper Roof?

When it comes to metal roofs, copper is one of the most beautiful, durable materials. 

With its rich, earthy hue and rustic appeal, a copper roof can make any building stand out from the crowd. 

But just like any other roof material, copper needs to be maintained for it to look its best.

And that includes cleaning it now and then. But depending on your copper roof type, different cleaning techniques may be necessary. 

In this article, we’ll provide some tips on cleaning a copper roof without damaging its beautiful finish or underlying structure. 

How To Clean Copper Roof?

Copper roofs are known for their distinctive patina—a lustrous greenish color—that develops over time as the natural minerals in the air interact with the metal. 

The patina helps protect the roof from corrosion and weather damage, but it can also be a turn-off if you want to maintain that shiny copper look.

Copper roofs need a certain level of maintenance to stay looking great and functional.

One of the basics for any copper roof is cleaning. Cleaning your copper roof regularly will help keep it looking new and prevent rust from forming. 

How do you clean a copper roof? The key is to clean it without damaging the patina, which will help protect your roof for years to come. 

This can be done with simple soap and water solutions or specialized copper cleaners. 

Preparing to Clean the Copper Roof

When cleaning the copper roof, you need to do some preparations first. Here are some steps you should take:

  1. Assess the Damage:

Before attempting to clean the copper roof, inspect it first and see how much of the surface has been damaged by corrosion. 

Ensure to note what damage there is, as this will determine what cleaning products and methods you’ll need for the job.

  1. Choose an Appropriate Cleaner

Depending on the corrosion damage’s severity, you must choose an appropriate cleaner that effectively removes more stubborn residues. 

A mild detergent or acidic cleaner should suffice if you have lightly corroded metal. For heavier stains, a metal-safe brush or abrasive cleaner might be necessary.

  1. Check for Safety Precautions

Before you start scrubbing away at your copper roofing, make sure you check all safety precautions first. 

Wear protective clothing and a mask to minimize skin and respiratory exposure when handling any chemicals, solvents, or cleaners during the cleaning process.

Cleaning your copper roof doesn’t have to be complicated if you prepare correctly beforehand—so remember these steps before starting!

Material and Tools Required

When cleaning your copper roof, you need the right materials and tools. Luckily, you don’t need any special supplies—just items that can be easily found around the house. Here’s what you’ll need:

  • A soft-bristled brush or cloth
  • A mild, non-abrasive laundry detergent and baking soda
  • Warm water
  • A hose or garden sprayer
  • Protective eyewear and gloves

Once you have all the necessary supplies, you can start cleaning your copper roof. Wear gloves and protective eyewear when handling detergents and cleaning solutions, as these can be harmful if used incorrectly.

Step-by-Step Instructions on Cleaning a Copper Roof

Clean your copper roof the right way, and you’ll have it looking amazing year after year. 

Here’s a quick step-by-step guide to help you out:

Step 1: Clean out the surface 

Make sure the roof is dry and free from dirt and debris.

Step 2: Scrubbing 

Use a soft brush or cloth to scrub the surface of the copper roof. This will help loosen up any dirt, grime, and corrosion.  

Ensure to use soft-bristled brushes when cleaning, as using hard bristles can cause damage to the copper roof patina. 

Mix a solution of water and mild detergent, then gently scrub this onto the copper roof with a soft brush or cloth. 

Also, don’t use abrasive cleaning materials like steel wool, which could damage the copper roof patina.

Step 3: Encountering tough spots 

You may need something more potent than soap and water for tougher spots. Specialized cleaners might be needed for these harder-to-remove spots, such as rust or bird droppings.

You’ll need a gentle bentonite-based cleanser, a soft cloth or brush, and an oxygenated cleaner. 

Mix the bentonite and oxygenated cleaners until they form a paste, then apply it carefully to the surface of your roof using your cloth or brush. 

It’s best to start with milder solutions, such as white vinegar or lemon juice, before trying anything harsher.

Gently buff it in circles and let it sit for about 20 minutes before rinsing it with clean water. 

This method will help remove dirt and grime without stripping the copper roof patina away.

Step 4: Rinse 

Once you have finished washing and scrubbing the metal roof, rinse it off with cold water. 

Rinse off with clean water using a garden hose or pressure washer set on a low setting and at least two feet away from the copper panels.

Step 5: Drying 

Let the roof air dry immediately after you rinse it off so that no standing water is left on top of it.  Or you can use a soft cloth like a microfiber towel to dry it off and remove any remaining dirt or debris. 

If left sitting, water will leave mineral deposits that can quickly corrode your copper roof patina over time instead of maintaining its beautiful hue!

Step 6: Finishing Touches

You’ll want to double-check for anything that might be stuck on there that needs to be scraped off after drying.

Finally, if you want an extra layer of protection and shine to your copper roof, you can apply a protective sealant or wax over the entire surface. 

This will help preserve the metal’s luster and protect it from future damage caused by exterior elements such as sun exposure, wind, and rain.


When cleaning your copper roof, you have a few options. You can use a mild soap, water scrub, or a stronger cleaner for tougher jobs. 

For those who want to use the most natural cleaner, you can also use baking powder, salt, and vinegar paste.

No matter which option you choose, be sure to take precautions when cleaning your copper roof. 

Test an inconspicuous area of the roof first and use protective equipment when cleaning. The key is to be gentle to avoid damaging the copper surface.

With the right tools and techniques, you can keep your copper roof shining and looking good as new! 

When taking care of your copper roof, it’s important to remember that a little bit of cleanliness goes a long way. 

Whether it’s just regular maintenance or more detailed cleaning tasks that are needed occasionally, keeping your roof in top shape will keep its lifespan longer and make all your neighbors jealous!
