Is It Ok To Pressure Wash A Metal Roof?

When it comes to your home, your roof is one of the most important areas of your property.

That being said, taking care of your roof can involve washing it. However, a lot of people have the question about whether or not pressure washing a metal roof is okay. So let’s answer that question in the article below.

Can You Use Pressure Washing On Metal Roofs?

Let’s talk about some of the factors that determine “Should you pressure wash a metal roof?”

Pressure Required

If you need around 1,000-2,000 pounds per square inch (PSI) of pressure, then pressure washing the metal roof may be appropriate. You should always exercise caution to avoid damaging the roof.

The Type Of Metal

Depending on the type of metal that your roof is made out of, this could mean that you are able to pressure wash it versus not pressure wash it. Stronger metals can withstand the pressure and heat of power washing.

Weaker metals may not be able to stand up to it. Furthermore, metals that are more resistant to corrosion and rust can be pressure washed, but some metals will simply turn red with corrosion eventually if they’re exposed to too much water.

If The Roof Is Waterproof Or Not

There are several things you can do to waterproof a roof. This includes coatings, preparation, seams, joints, and more.

You should consult roofing professionals to understand whether or not you should pressure wash your metal roof. After all, there is more to roof washing than meets the eye.

Metal Roofs Commonly Used

There are various types of metal roofs available today:


This is common thanks to its affordability and durability. You can get various grades or finishes for steel roofs.


Aluminum is more lightweight than traditional steel, but it still offers some corrosion resistance. It’s best for coastal regions where it can stand up to salt. It’s slightly more expensive than steel, but you don’t need to maintain it quite as often.


Copper is expensive roofing. It’s incredibly elegant, but it can be prone to corrosion if not treated properly.


Zinc is low-maintenance and has a long lifespan. Its durability lends itself to roofing. It’s also a very environmentally-friendly material that can be recycled after it’s no longer being used.

The Advantages Of Metal Roofs

Metal roofs can be very energy-efficient thanks to their durable nature. They reflect sunlight, which can reduce the cost that you need to spend for cooling.

They can also stand up to winds and extreme weather conditions much better than other types of roofing materials.

However, roofs can be prone to denting from falling branches or other debris. Furthermore, if the metal is not treated properly, it can be vulnerable to rust and corrosion.
