Tips on How to Clean a Metal Roof

Home > blog

Cleaning is important for numerous areas of our home and property, and one area that cannot be ignored here is your roof. If you have a metal roof for any home or building on your property, cleaning is luckily a very simple and straightforward process.

At Mid Michigan Metal Sales, we’re proud to offer a wide range of metal roofing panels, metal roofing shingles and other metal roofing supplies, plus expertise on how to properly utilize and maintain these products. Here are some basic tips on cleaning metal roofs of any kind, ensuring that they remain safe, functional and aesthetically pleasing all at once. 

Consider the Weather

Our first tip here regards your choice of precisely when to go about cleaning your metal roof. Because safety is so important, we strongly recommend against undertaking this process when there’s any risk of slips or falls. Specifically, avoid cleaning your metal roof during times of precipitation like rain or hail, plus during especially icy and cold times – these can make the roofing surface very slippery.

Rather, you should look for a dry day with calm winds and mild temperatures. If there’s any severe weather in the forecast, simply delay your cleaning until conditions improve.

While this may not always be possible in your area, the absolute perfect day for cleaning a metal roof is one that is overcast, but not raining or snowing. This is because full sun can heat up the metal roof, making it too hot to safely clean. Instead, choose a day with cooler temperatures and cloud cover.

Start With a Visual Inspection

Before you even begin the cleaning process, take a look at your metal roof and assess any potential issues that may need attention. Look for any areas of damage or corrosion, as well as any debris or leaves that have accumulated in the gutters or on the roof itself.

If you spot any major issues, such as large dents, rusting or missing panels, it’s important to address these before moving forward with cleaning. Contact a professional for repairs if necessary.

Gather Supplies

To clean your metal roof effectively and safely, you’ll need some basic supplies. This includes a ladder or scaffolding to access the roof, a garden hose with an adjustable nozzle, and cleaning solutions that are safe for use on metal surfaces.

It’s also important to wear protective equipment, such as gloves and safety glasses, while working on your roof. These items will help prevent any injuries from occurring during the cleaning process.

Safety is Paramount

As you go about cleaning your metal roof, always prioritize safety. This means being aware of your surroundings and taking necessary precautions to prevent falls or accidents.

Avoid walking on the roof as much as possible, as this can not only be dangerous but may also cause damage to the panels. Instead, use a ladder or scaffolding to access different areas while maintaining stability and balance.

Avoid Harsh or Unnecessary Chemicals

As we’ll go over in just a bit, almost all metal roof cleaning can be accomplished with relatively simple solutions. Avoid harsh or abrasive chemicals, as these can cause damage to the metal surface and potentially void any warranties you may have on your roofing.

For instance, while it may initially seem like a good idea to use a power washer to quickly clean the roof, this can actually cause dents or scratches in the panels. Stick to gentler cleaning methods for the best results and to preserve your roofing.

Cleaning Solutions to Use

Here are some of the basic cleaning solutions that will typically get the job done for metal roof cleaning:

  • Simple water from a hose: In many cases, dirt and debris can be removed with just a garden hose and a good spray nozzle. Simply spray water on the roof and use a brush or long-handled mop to scrub away any loose debris.
  • Mild soap or detergent: If you prefer, you can also add some mild soap or detergent to your water for a more thorough clean. Be sure to rinse well after scrubbing.
  • White vinegar: For tougher stains or areas with mold or mildew, white vinegar can be an effective and natural option. Mix equal parts vinegar and water, spray onto the roof, and scrub with a brush or mop. Rinse well when finished.
  • Baking soda: For greasier stains, baking soda mixed with water to form a paste can help break down the oils. Apply the mixture to the stain and let sit for 15 minutes before scrubbing and rinsing.

With the right basic supplies and a few simple cleaning solutions, you can easily maintain the cleanliness and functionality of your metal roof. Remember to prioritize safety at all times, and don’t hesitate to contact a professional if you have any concerns or need assistance with repairs. Keep your metal roof in top shape for years to come with proper care and maintenance.
