One of the great things about a metal roof is that it has an incredibly long lifespan. If you take proper care of your metal roof, you may never need to replace it. Cleaning your metal roof at least once a year is one of the essential maintenance steps you need to take in order to ensure your roof lasts a lifetime. Before the warm weather is gone, make sure that you spend a few hours cleaning your metal roof.

Necessary Supplies

You don't need very many supplies in order to clean a metal roof. You are going to need either a wire brush or a flat-bladed putty knife, some trisodium phosphate, a bucket, a soft scrub brush, and a power washer.

First Clean Away Any Corrosion

The first thing you need to do is inspect your roof for corrosion. When exposed to the elements, metal can rust. In order to prevent additional corrosion, you need to clean up any rust that you spot on your roof. You can remove the rust by scrubbing it away with a wire brush or you can use a flat-bladed putty knife to scrap it off.

If you have recently painted your home and a little extra paint got on the roof, you can also use the same method above to remove any excess paint.

Create the Cleaning Solution

Next, you are going to need to create the cleaning solution. Mix one cup of trisodium phosphate with two gallons of water inside of a bucket. You may need to make this cleaning solution more than once, depending on the size of your roof.

Scrub Your Roof Down

Once you have created the cleaning solution, take it up to your rooftop. Dip a soft scrub brush into the solution and use it to scrub your roof. Apply the solution liberally to your roof, then scrub away. This will remove any dirt and also kill any mold or mildew that is present.

To make the job a little easier on you, instead of using a handheld scrub brush, consider investing in a soft scrub brush that was designed to be used to wash a car. These scrub brushes are attached to long handles, which make them much easier to use.

Use a garden hose to gently rinse each section of your roof after you scrub it down to get rid of any residue. Again, keep in mind that it may take multiple buckets of cleaning solution to scrub down your roof depending on how dirty it is.

Spray It Down

Finally, hook up your power washer and use it spray down your roof. You'll want to start at the top or the steepest part of your roof and uniformly work your way down; that way, the all the dirt will get washed down and off your roof as you work. Work top to bottom, right to left with the pressure washer.

You should be able to complete this entire process in a day. However, if you have an extremely large roof, you may want to do this process in sections. Finally, remember to exercise caution when standing and working on your roof.
