How to Clean a metal roof



Your home's first line of defense stands above your head, securing you from the elements. A well-maintained metal roof not only adds aesthetic appeal but provides protection and could even increase your property's value. However, the tricky part is in the upkeep, and no season requires more attention to detail than when spring arrives, shedding light on winter's toll. It’s crucial to understand the nuanced art of cleaning metal roofs to ensure it’s not only sparkling but that you and your loved ones remain safe during the process. In this comprehensive guide, we’ll address the ins and outs of metal roof washing for homeowners, property managers, and anyone in-between.

A Glimpse at the Grandeur of Metal Roofs

Metal roofs now rival traditional asphalt roofs, boasting multiple advantages in durability, sustainability, and energy efficiency. Issues like algae, general soiling, and standing debris can diminish the luster and life of these significant investments. Unlike traditional shingles, metal roofing demands a methodical approach to cleaning to avoid damage and maintain its integrity. This is where a tried-and-true cleaning regimen comes into play, ensuring your metal roof’s longevity and performance.

Unveiling the Vulnerabilities

Before we venture into the cleaning process, it’s important to recognize the vulnerable aspects of a metal roof. Panels, particularly those with exposed fasteners, can become prone to corrosion if not properly cared for. Additionally, the coatings on your metal roof need to be factored in – high gloss finishes might require different cleaning methods than matte finishes.

Selecting Your Weapon of Wash

When gazing upon the arsenal of cleaning tools and solutions, it's the method that makes the master. For metal roofs, the pressure is not your friend. High-pressure power washing can introduce water into unwanted places and compromise seals and coatings. A soft touch of soft washing, on the other hand, with the right combination of bleach, soap, and water, is the safest and most effective route.

Fine-Tuning the Formula

You need to use a strong Sodium Hypochloride mixture to get the results you are looking for. Due to the size of a roof, mixing bleach soap and water in a pump sprayer will take you forever and will be very hard to apply, especially if you have a second story. Using a proffesional roof cleaning company is going to be your best bet for top results as they will already have the equipment needed to not only clean the roof but take measures to protect any trees and plants around the home. This is not really a job for a DIY enthusiast.

The Art of Soft Washing

Soft washing involves a non-pressurized mixture of cleaning solutions gently applied to your roof to break down and remove grime. This low-pressure method allows the solution to sit and work effectively without causing damage. Remember, when working with bleach, always take safety precautions and wear protective gear.

The Rhythm of Roof Washing

Now that we understand the essentials, it’s time to find the melody of the wash. A coordinated cleaning routine will maximize efficiency and effectiveness, guaranteeing a consistent sheen across your roof’s expanse.

The Step-by-Step Choreography

• Prep is Paramount: Start with a thorough inspection of the roof and surrounding area. Clear any debris that could potentially fall onto the yard or into the gutters.
• Application: Using a low-pressure spray, apply the cleaning solution from top to bottom in a uniform manner. Avoid spraying at an upward angle to prevent water from getting trapped under the panels.
• Dwell Time: Allow the solution to sit and do its job for about 10-15 minutes. This will give it enough time to break down and loosen the grime.
• Gentle Rinse: Rinse the roof thoroughly with plain water, again going from top to bottom. Again, steer clear of high pressure to prevent damage.
• Post-Wash Inspection: Conduct an extensive check on the roof and gutters to ensure all debris is removed. Only if it's completely necessary and within your skill set, conduct repairs yourself or seek assistance.

The Dance of Safety

Just as cleanliness is crucial, safety must never be neglected. Never attempt to clean a metal roof when it’s wet or immediately after a rainy day. The inherent slip of the metal surface, coupled with water, creates a hazardous environment that could lead to accidents.

Balancing the Act of Maintenance

Consistency is key. A well-thought-out cleaning schedule, often in line with other home maintenance, not only keeps your roof safe but can also be a preventive measure against other issues in your home's exterior.

Timing Is Telling

You’ll find that every home's environment and location will dictate the required frequency of washes. Coastal regions with high humidity and more rainfall might need cleaning more than once a year, while drier, inland areas could see results from bi-annual cleanings.

Climate vs. Cleanliness

Understanding your local climate and how it can affect the state of your roof is essential for proper maintenance. Identifying the threats your roof faces—be it moisture build-up, snow, extreme temperatures, or heavy pollution—allows you to adjust your cleaning schedule accordingly.

The Shine of a Job Done Right

A clean metal roof is not only a sight to behold, but it also performs its duties more effectively. Regular care and the use of proper cleaning techniques ensure that your home's armor stands as it should, ready for whatever skies may bring.

Keep it Documented

Maintaining a log of when the roof was last cleaned and inspected is a pragmatic way of tracking your home’s maintenance. These records serve as a reference for future cleanings and can be valuable for insurance and resale purposes.

Final Thoughts

Your home deserves the best, and a meticulously maintained metal roof is an integral part of that commitment. Approach cleaning with the vigilance it demands, and you’ll not only protect your investment but also present a shining testament of your devotion to home care. Remember, the safety of you and your family is non-negotiable. Whether you decide to take on the task yourself or engage professionals, make the spring call to action for your metal roof's next chapter – one of longevity and vitality. And should you find the process overwhelming, be it for time constraints or comfort level, rest assured that trustworthy hands stand ready to secure the beauty and essence of your home. After all, as with any treasure, a metal roof is best appreciated when it gleams.
