How to Clean a Metal Roof in 9 Steps

Services for Real Estate Pros with

We all know that metal roofing is a big investment in homes or commercial buildings and requires proper maintenance. They are durable, energy-efficient, long-lasting, and much more, but they cannot be ignored when maintaining them to enhance their longevity. But older metal roofs can look dirty and if you’re trying to sell your home or business this can affect not only the sales price but the length of time it takes to sell. If you are thinking about putting your home or commercial building on the market, consider cleaning your roof first.

Why cleaning the roofs is necessary?

To enhance the longevity of metal roofs, cleaning is an important function.

Maintaining Curb Appeal

 No one wants to see dirt or an unkempt roof, especially when you have paid a good amount of money on its installation. That is why cleaning dirt is necessary to keep the metal roof clean, and this will also help prevent mold growth on different parts of the roof, which will decrease its worth and lower the price of the home.

Removing Trapper Debris

Sometimes tree branches, leaves, dirt, and other debris can pile up on your roof, which can cause various kinds of problems like rust, mold, scratches, and breakage. The debris also becomes a point of drawing unwanted pests to stay on the roof from where they might enter your home if there is a breakage.

To Extend Roof’s Lifespan

 One of the most important concerns of cleaning and maintaining the roof is for increasing the roof's lifespan. Through this, you will preserve the roof's paint and keep it clean for the ones who want to buy your house, and the debris will not cause much trouble for your home.

How to clean the Metal Roof?

Many homeowners fail to complete this task because they cannot clean the metal roofs. Cleaning the metal roofs is an important task to increase the longevity of it. The below-given process will help you safely avoid unwanted damage or injury to your metal roofs while cleaning them.

  1. Never do it alone; always bring someone with you in case of any emergency.
  2. Wear shoes with good traction, and make sure you do not step on any material other than your roof because it might cause you to slip or create a dent in the roof.
  3. Try to use additional safety equipment such as harnesses to protect yourself from a potential fall.
  4. Use an OSHA-approved safety ladder.
  5. Try reading the directions for any cleaning product which you are thinking of using for your roof. Some products can be toxic or can cause a chemical reaction in sunlight, which might harm the roof.
  6. Use a broom or a leaf blower to remove all the leaves and branches or any other debris present on the roof from the ground. You can climb on the roof to do this kind of work.
  7. Rinse away dirt and dust with water.
  8. Wash stubborn stains with a mix of dish soap and water using a sponge or soft brush.
  9. Always consult a professional before using any chemicals because they can react and can cause damage to the metal roof.
  10. Roof-A-Cide is a great product for killing and removing algae

Signs of Damaged Metal Roof:

Mould, Rust, or Corrosion

Remember, anything growing on the metal roof surface is a bad sign because it will damage the roof and even cause breakage in it. This is why remove and clean it before it gets worse.

Loose Panels of Flashing

 Most elements of your metal roof are built to withstand different weather events, through improper installation, or severe storms could result in loose flashing or panels. This is a clear sign that your roof needs service.

Visible Dents

Deep dents, scratches, and gashes in the metal roofs not only allow water to stay there for a longer period and cause rust or algae growth and can also cause breakage. Moreover, the corrosion caused by this can worsen the integrity of the roof.
