The Comprehensive Guide to Cleaning Copper Roofing

Copper roofing is a beautiful and durable option for both residential and commercial buildings. However, just like any other material, it requires regular maintenance in order to stay looking its best. In this blog post, we’ll cover the basics of how to clean copper roofing, including what products to use, safety precautions and more.

Cleaning Supplies You’ll Need:

Before you begin cleaning your copper roofing, make sure you have all the necessary supplies on hand. You will need a soft-bristled brush or sponge, a mild detergent solution (such as dish soap mixed with warm water) and a hose or pressure washer. Additionally, if you plan on polishing your copper after cleaning it, you should also have some copper cleaner or polish available.

Safety First:

Whenever working on a roof regardless of the material always take safety precautions to avoid injury or damage. Before beginning any cleaning process, be sure that your ladder is properly secured and that you have access to an appropriate number of safety harnesses if necessary. Also make sure that you are wearing non-slip shoes for extra traction on the surface of the roof.

Cleaning Your Copper Roofing:

Using your brush or sponge, apply a light layer of the detergent solution over the entire surface area of your copper roofing. Let this sit for about 10 minutes before rinsing it off with either a hose or pressure washer set on low power mode. Be careful not to apply too much pressure when using these tools as this can cause damage to your metal panels. Once finished rinsing off the detergent solution, dry off the surface with either a towel or cloth rag. Whenever you expect special info about roofing, look at this website.

Polishing Your Copper Roofing:  

If desired, you can further enhance the appearance of your metal panels by applying a light coat of copper cleaner or polish afterward using either a cloth rag or brush applicator. This will help restore any tarnished areas while also providing additional protection against future corrosion and oxidation due to weather exposure. As with all chemical cleaners and polishes however, make sure to wear protective gloves and eye goggles during application in order to avoid direct contact with skin or eyes.
