Gather All Of Your Tools The Checklist
We already know youre going to start with a great pressure washer. You will likely want one that is gas-powered to ensure that you have all the power you need to remove any gunk and debris from your metal roof.
Some jobs can be accomplished with normal cold water from a garden hose, but the most heavy-duty jobs will require hot water and a power washer than can not only power but heat your water.
You will also need a great ladder that is adequately sized for your roof. What works for screwing in a lightbulb in the home will not work for climbing to the top of your house.
Always make sure that your ladder has padded and protected steps before you climb to your roof and begin washing. Starting with a safe grip from the bottom up will ensure safety and accuracy when power washing. Other musts include:
- Dont forget to find an extension cord that is more than adequate for reaching your roof. Think about the bushes youll have to snake around, as well as the safest place to plug in.
- Youll need a functioning garden hose that is long enough to easily reach the roof for rinsing. And dont forget a good spray nozzle to go along with it.
- You may also want to have a small scrub brush on hand or a small scraper, should you find something stubborn that needs a little extra convincing.
- Dont try to do it all alone. Enlist a helper on the ground to hold the ladder and adjust the pressure if and when you need it.
A reminder about additional safety requirements:
Gunk And Water Deposits
Your most common deposits will be washed away with a good power washer. Typically, cold water will get the job done. The most severe gun and debris will require the use of hot water in order to clean your metal roof.
Start by spraying your roof with a hose or a normal wand attachment. This will give you a better idea of how hard you need to work to rid your roof of gunk and deposits. By the time you break out the power washer, you will know exactly where your problem areas are and how you need to wash them.
Stickier substances may not come off with a power washer alone. Although the power washer is an essential tool for cleaning a metal roof, you will likely need to implore the aid of other tools and solutions in order to rid your metal roof of gunk and buildup.

Tip #1 Use A Stabilizer For Your Ladder
You will be using the ladder to climb up to your roof and go back down. You can put the ladder into a flat surface or through the gutter at the roofline. As the ladder may slip into it, a stabilizer can be the best option for you, especially if you are afraid of the heights or want to ensure that the ladder wont come off.
Dry And Wax Galvanized Steel Using A Soft Cloth
An essential step in cleaning galvanized metal and stainless steel is always to dry it with a soft cloth. Never skip the drying process or store steel in a wet or poorly-ventilated location. Otherwise, you may leave moisture behind that contributes to water spots.
If youre wondering, will stainless steel rings tarnish the answer is yes. Any metal eventually will tarnish, but stainless steel is less prone to tarnishing than to becoming dull or discolored over time. Always rinse the soap from the metal and completely dry it.
Apply a store-bought metal polish next using a soft lint-free cloth. Waxing metal helps small scratches appear nearly invisible and increases the lifespan.
If you go to the car wash to regularly clean a large galvanized surface like a car or truck hood, for example, you might skip this final step.

While a power washer takes care of most grime on roofs, the job may call for a little elbow grease. Having a few types of scrubbing options to help with removing stuck-on particles and hard-to-remove dirt spares you from unwanted frustration.

Wash Galvanized Steel With Soapy Hot Water
Follow the rinse with a hot water wash. It is the fastest way to clean galvanized metal. All you need for this basic clean is hot soapy water, a bucket to hold it in, and a soft brush.
- Nylon or plastic brush
Add detergent to a bucket of water and scrub the entire steel surface using a nylon or plastic brush. Pay attention to problem areas or anywhere dirt builds up.
Only scrub galvanized metal using this method sparingly. Remember to use a nylon or plastic brush, or the steel could interact with the color of the brush and change colors.
You can also use this remedy to try to strip spray paint from metal, too.
Why Does Cleaning Galvanized Metal Require Extra Care
Galvanized metal has an outer layer of protection against oxidation and corrosion, which is what makes steel last so long. Its an effective mode or protection.
The coating is zinc oxide, and the zinc both protects the metal chemically and physically. It creates a barrier from outside harm and reacts as a sacrificial anode, which means the coating pulls any corrosive effects into itself rather than affecting the metal underneath.
However, the zinc coating becomes less effective over time. Eventually, the coating ceases to exist. Regular cleaning is the only way to help the barrier last longer and keep galvanized metal looking like new.
