Metal roofs require little maintenance. However, regular cleaning will keep your roof looking great year after year. It’s important to clean your metal roof if it has been painted or coated with a special coating. This coating protects the metal from rusting. It’s designed to withstand the elements but will still protect your roof with regular cleaning.
It is a good idea to clean your metal roofing at least once a year or whenever you see stains, mildew, or moss.
Why your metal roof should be cleaned
It is important to maintain your metal roof’s appearance and longevity. The paint will eventually begin to deteriorate due to UV rays and oxygen exposure. Chalking is a sign that paint has begun to wear away from the roof’s surface. This does not necessarily mean that your roof is damaged, but it is an indication that your roof needs to be cleaned.
Because it is easy to avoid, excessive chalking isn’t usually covered by warranties. Regular maintenance such as cleaning and spot-touch-ups can help reduce the risk of metal roof oxidation.
It’s easy to clean your metal roof. This is a great way to prevent rust staining and mold growth. You will need to clean away any dirt, leaves, and pollen as well as tree sap, acid, or other substances that have been deposited by rain.
How to clean your metal roof
All you need to clean your metal roof is a sponge, a soft-bristled toothbrush, or a cleaning pad. Use non-abrasive products only. The paint could be damaged faster by scratches, as oxidation can penetrate deeper into the surface.
In most cases, you can use water and your cleaning tools to clean up debris. To help remove any sap, grease, or other substances that have built up, you can mix a mild detergent with the water. You can use detergents for car washing, dish soap, and laundry detergent on metal roofs. You can spot-clean stains with bleach, rubbing alcohol, or mineral spirits, but not the entire surface.
These steps will help you protect your roof from rust, mildew, and other contaminants each year.
- Rinse everything with water.
- Add 1/4 cup of detergent per gallon to the water.
- Use a sponge or cloth to apply the solution.
- After 5-10 minutes, rinse well.
- Use safe cleaners to spot-clean mold, mildew, and rust.
Do’s and don’ts of cleaning a metal roof
- Do not use a high-pressure washer.
- Do not use sandpaper or steel wool to clean mold, mildew, or rust stains.
- Do not allow toxic run-off to reach the ground when you use chemicals for staining.
- Use a little bleach and a suitable detergent to remove mildew or mold stains.
- If you are unsure about how to remove a stain, contact an expert.
- Wear protective clothing if cleaning your roof by yourself. This includes glasses, gloves, and shoes that have good traction.
Use safe techniques when cleaning your roof, including fall protection, ladders that conform to OSHA standards, and a buddy.
Don’t be afraid to ask for assistance. Your metal roof doesn’t need to be cleaned by you. Hire a professional if you don’t feel like cleaning your metal roof, don’t know how to do it safely, or aren’t willing to take on the task. You can protect your metal roof by taking care of it year after year. It will last a lifetime.
