How to Clean a Metal Roof? Best Methods for Metal Roof Maintenance

Metal roofs are quickly becoming a popular roofing option for many homeowners. They can last up to 3 times longer than other types of roofs, which is ideal during unsteady economic times.

If you have invested in a metal roof for your home, then you already know about the benefits of owning one. However, did you know that cleaning it can prolong its life?

How do you clean a metal roof? What else can you do to maintain your roof? When do you need a professional cleaner?

This short article will answer these questions to help you keep your metal roof in pristine condition.

The Reason You Should Clean a Metal Roof

Metal roofing is highly durable, typically needing little maintenance. However, an occasional cleaning can preserve your roof’s integrity and ensure it looks its best. Cleaning your roof also gives you a chance to inspect for damage. Roof leaks can cause a mess (or two) inside your home. Promptly repairing any problems can prevent them from snowballing into costly disasters.

How to Clean a Metal Roof

Before attempting any cleaning or maintenance tasks, it’s crucial to prioritize safety. Ensure you have the necessary protective gear, including gloves, goggles, and non-slip footwear. If you’re working at heights, make sure your ladder is secure and consider having a safety harness in place. Additionally, be mindful of any electrical hazards or power lines that may be in the area. 

Choosing the Right Metal Roof Cleaning Method

Water and Dish Soap

You can use a bucket full of water and sudsy dish soap to clean your metal roof. You will also need a non-abrasive sponge, like a car washing sponge, or other cloth to scrub the grime away, which can take a while depending on how dirty your roof is. You can use a soft bristle brush with an extension arm, but take specal care not to scratch the surface. Resist the temptation to use any kind of abrasives which may take off the coating and allow rust to set in.

Water and a Roof Detergent

If you need something stronger than dish soap, you can mix roof detergent with water. Follow the detergent’s instructions to pour the proper amount. You will still have to work at the tough spots but you could see better results.

Water and Vinegar

Cleaning with vinegar is sometimes safer than using harsh chemicals. One cup of vinegar and two cups of water can be the solution that cleans and shines your metal roof to perfection.

Water and Bleach

Bleach can damage your metal roof’s finish. However, it can eliminate any moss, mildew, or mold you might find. Some sources suggest combining one part bleach for every eight parts of water and letting the solution sit for five minutes before rinsing.

Pressure Wash

Pressure washing is probably the most effective method to clean your metal roof. You’ll need a bucket of soapy water and a pressure washer to do the job. Use a pressure washer with a wide-angle spray nozzle to remove dirt, debris, and mildew. Keep the pressure setting low to avoid damaging the roof’s surface. It’s important to maintain a safe distance from the roof and use sweeping motions to prevent water from penetrating underneath the panels.

What to Look for When You Clean Your Roof

If you are already cleaning your roof, you should take a moment to check it for damage. If you see rust, bent panels, or holes, then you should contact roofing experts to repair the problems.  It is also important to check for and remove any debris, leaves, or branches that may have accumulated on the roof.

When to Contact a Professional Cleaner

What if you know how to clean a metal roof but you don’t have the time or desire to do it? Maybe you can not climb a ladder and hop on top of your home. If you find yourself unwilling or unable to clean your metal roof, then you should contact a professional cleaner.
