If you’ve already acquired or are considering purchasing a painted metal roof, you’re probably aware it’s a significant investment with numerous advantages, including lifespan and durability. But what if we told you that leaving one thing undone could lead to your roof failing or requiring replacement sooner than expected?

Cleaning your metal roof is one of those things. It is correct. Cleaning your painted metal roof has numerous advantages, but you must do so correctly to avoid harming the metal or its accessories.

Cleaning it regularly, like any other household or outdoor object, will extend its life. Periodic cleaning of a metal roof helps maintain the panels’ integrity and removes any particles on the surface that could harm the paint system or even the underlying.

Fortunately, paint systems are tough and built to last, but they must be cleaned regularly to maintain the resin’s and coating’s strength.

Why Do You Need To Remove Creosote From Metal Roof?

Chemicals in particular atmospheres, such as acid rain and pollution particles, can cause a metal roofing paint system to degrade prematurely. Inspecting if the paint on your roof is chalking is one of the simplest ways to identify if it is deteriorating. Chalking is a yellowish residue that can appear over time on a painted or coated metal surface.

The resin in the paint system begins to break down and degrade as a panel is exposed to sunlight and UV radiation. When the resin begins to break down and is exposed to sunlight and contaminants, it loses its adherence to the surface, and the degraded particles turn white.

A metal roof may be cleaned with a variety of cleaning tools. There are times when nothing but water is required for cleaning. However, there are times when a stronger cleaning product and a tool to wipe or wash the panels are required. It all depends on the situation.

Use A Homemade Cleaning Solution

Because it is non-invasive and simple to use, this is the cleaning solution most people need to use while cleaning their metal roofs. This category includes mild laundry detergents, mild dish soap, and cold or hot commercial detergents.

To make a homemade cleaning solution, you will need to mix a half cup of detergent with a gallon of lukewarm water.

Once you have done with the solution, it’s time to clean the roof it using a sponge brush. If the layer of creosote is hard, use a soft-bristle brush for gentle scrubbing. Make sure to let the solution sit on the metal surface for at least for 15-minutes before rinsing it off.

Deal With Stubborn Rust Stain

Metal particles that cause rust spots on a metal roof’s paint surface may touch your metal roof, depending on where you reside. At first glance, you may believe the roof is damaged or has begun to erode prematurely, but this is not always true.

It’s only when it comes into touch with uncoated metal pieces and particles that it rusts. Remove any debris or fragments creating rust stains.

  • 1 part diluted hydrochloric acid Plus five parts water
  • Apply a rag to the affected areas and wipe in a circular motion.
  • Rinse as soon as the rust stain has disappeared.
  • Keep the solution off the surface for no more than five minutes.
  • Allow no time for the mixture to dry on the surface.

Don’t Use Unnecessary Cleaning Products On The Metal Roof

In our suggestions, you follow the instructions provided to you.

Overuse or abuse, such as concentrating a cleaning solution too much, mixing it with other chemicals, or using too much of a solution for too long, can damage the metal or paint system, voiding one or more warranties and leaving you with the cost of a metal roof replacement. Additionally, in rare cases, overuse or abuse can hasten deterioration.

The blemish you’re trying to remove may be a scratch in the coating caused by various factors, including installer error or a small branch hitting the roof during a storm. The most important thing to remember when applying touch-up paint is to follow the manufacturer’s instructions.
