Metal roofs are a great investment because they help keep your home cool in the summer and warm in the winter. However, they have one major drawback: They often get very dirty over time. Over time, dirt can build up on the surface causing discoloration and other problems. Fortunately, you don’t need to replace it just yet! You can pressure wash it to remove all of that dirt buildup so that your roof will look as good as new again!

Here are some tips to make sure you pressure wash your metal roof properly.

Clean Your Roof With a Power Washer Before You Pressure Wash It

You can’t simply pressure wash without cleaning it first. If you try to, all that dirt will get pushed into the nooks and crannies which could lead to scratches or other damage over time. So before you use a power washer, make sure that it is 100% clean!

Don’t Get Your Roof Too Wet When You Are Pressure Washing It

You want to make sure that you don’t douse with water when using a power washer. After all, if too much of the surface area gets wet then it will start to rust over time and need replacing before its time! So try not to use too much water pressure when you are cleaning.

Also, make sure to thoroughly rinse after you wash it. All of the dirt and grime will be sitting on top which means that if left there, water could seep down between crevices where rust or other issues can form.

Don’t Spray Your Roof When the Sun Is Shining Directly On It

If you spray with a power washer while it is exposed to direct sunlight, then the heat from the sun could warp and damage your metal roofing panels. If possible, try to clean after the sun goes down so that it will be cooler and less likely to warp.

Pressure Wash in the Direction of the Water Flow, Not Against It

When you are pressure washing, make sure that the water flow is coming towards you and not away from you. This may seem like common sense but if done incorrectly then it could lead to scratches on your metal roofing panels or worse yet, leaking!

Use a Low-pressure Setting to Avoid Damaging Your Roof

Although using a power washer is the best way to clean your roof, it’s very important that you don’t use too much water pressure. If you are using a gas powered power washer, set your nozzle at around 1800 psi or less. Any more than that could cause damage which can be costly in terms of repairs!

If you are using an electric power washer, set your nozzle at around 1500 psi or less. You will want to push the low setting on your pressure dial so that you don’t accidentally use too much water pressure when cleaning.

Make Sure to Remove Any Loose Debris From the Surface Before You Start Pressure Washing

Before you start washing, make sure that any loose debris is removed. If left behind then the dirt could mix with water and form mud which will work into crevices of your panels over time. Mud can also collect in low areas after being pushed there by a power washer nozzle so be sure to do a thorough job of removing it before you start cleaning.

Let Your Metal Roof Dry Thoroughly Before Applying Any Sealant or Coating

This will help prevent corrosion and rusting so it’s important that you let your roof dry thoroughly before applying any sealant or coating. If done too soon, the water will still be sitting on top of your metal panels which could lead to rust and corrosion over time if left there for months at a time.

Be Sure Not to Use Bleach When Cleaning Your Metal Roof

Never use bleach to clean your metal roof! Although it might seem like a good idea, the chemicals in bleach will cause corrosion on your metal panels if left there for too long. It can also eat away at any sealant or coating that you may have already applied which means you will need to reapply it over time.
