Metal Roofing Maintenance: Tips To Maintain Your Metal Roof

Metal roofs are a popular choice for homeowners due to their durability, longevity, and aesthetic appeal. However, like any other roofing material, regular maintenance is essential to ensure your metal roof continues to perform at its best. In this blog, we'll delve into essential metal roof maintenance tips, highlight the significance of upkeep, and outline key precautions during maintenance, all to safeguard your investment for the long haul.

Clean Out Gutters & Drains

Keeping gutters and drains clear of debris is crucial for maintaining the integrity of your metal roof. Clogged gutters and drains can lead to water buildup, causing corrosion and damage to the metal panels roof over time. To prevent this, it's essential to regularly clean out gutters and drains, especially after a hurricane or heavy rain when leaves and other debris tend to accumulate. Use a ladder and gloves to remove any debris by hand, or consider using a gutter cleaning tool for hard-to-reach areas. Once clear, flush the gutters and drains with water to ensure proper drainage and prevent potential issues.

Clean Off Dirt, Mildew, Stains, & Other Elements

Regular cleaning of your metal roof surface is necessary to remove dirt, mildew, stains, and other elements that can detract from its appearance and compromise its performance. Start by using a soft-bristled brush or broom to loosen any debris, then rinse the surface with water. For tougher stains, consider using a mild detergent or specialized roof cleaner, carefully following the manufacturer's instructions. Avoid harsh chemicals or abrasive cleaning tools that could damage the roof's protective coating.

Remove Leaves & Debris Stuck In Valleys & Dead Spots

Valleys and dead spots on your metal roof are prone to collecting leaves, branches, and other debris, which can trap moisture and accelerate corrosion. Regularly inspect these penetration point areas and remove any debris to prevent moisture buildup and potential damage to your roof. Use a leaf blower, broom, or your hands to clear out any debris, taking care not to damage the roof surface in the process.

Remove Branches & Sticks That Are Touching The Roof Surface

Overhanging branches and sticks can scratch or damage the surface of your metal roof, especially during storms or high winds. Trim back any branches or sticks that are touching or scraping against your roof to prevent damage to the protective coating. Use pruning shears or a saw to carefully trim branches, taking care not to damage nearby vegetation or structures.

Verify That No Other Metals & Materials Are Touching The Roof

Ensure that no other metals or materials come into direct contact with your metal roofing panels, as this can lead to galvanic corrosion. Regularly inspect the roof and address any contact points, such as metal flashing or vents, to prevent corrosion and prolong the life of your roof. Consider using non-metallic materials or insulating barriers to prevent contact between dissimilar metals.

Look For Scratches, Scuffs, Chipping, Flaking, Or Excessive Chalking/Fading

Inspect the surface of your metal roof regularly for signs of paint system damage, such as scratches, scuffs, chipping, flaking, or excessive chalking or fading. Addressing these issues promptly can prevent further deterioration and extend the lifespan of your roof. Consider using touch-up paint or protective coatings to repair minor scratches and protect against future wear and tear. If damage is extensive or severe, consult a roofing professional for repairs or replacement.

Why Is It Important To Maintain Your Metal Roof?

Maintaining your metal roof is crucial for several reasons:

#1: To Prevent Potential Problems

Having a regular maintenance schedule allows you to identify and address potential issues before they escalate into major problems. By conducting routine inspections and addressing minor issues such as loose fasteners or metal roof screws, damaged flashing, or small roof leaks, you can prevent water infiltration, structural damage, and other costly repairs down the line. Preventative maintenance also helps mitigate the risk of unforeseen emergencies and ensures that your roof can withstand the elements year-round.

#2: To Prolong The Life Of The Roofing System

Well-maintained metal roofing systems can last for decades, providing reliable protection for your home or building. However, neglecting maintenance can significantly shorten its lifespan and lead to premature deterioration. By regularly cleaning, inspecting, and addressing minor issues, you can extend the life of your metal roof and maximize your investment. Proper maintenance also helps preserve the warranty coverage of your metal roofing system, giving you peace of mind and long-term savings.

#3: To Keep Your Metal Roof Looking Great

In addition to protecting your property from the elements, maintaining your metal roof helps preserve its aesthetic appeal. Regular cleaning and upkeep prevent the buildup of dirt, debris, and stains, ensuring that your roof maintains its original beauty and enhances the overall curb appeal of your home or building. A well-maintained metal roof not only adds value to your property but also reflects positively on your attention to detail and pride of ownership.

Things To Avoid During Metal Roofing Maintenance

During metal roofing maintenance, it's important to be mindful of certain practices to avoid potential damage or safety hazards. Here are some key things to avoid:

Avoid Walking On Your Metal Roof More Than Necessary

While it's important to conduct inspections and perform maintenance tasks on your metal roof, excessive foot traffic can potentially damage the metal panels, especially if they're not designed to bear weight. Limit walking on your roof to essential maintenance tasks only, and use caution to avoid denting or scratching the surface.

Avoid Painting With A Sprayer Around Your Home

If you're planning to paint the exterior of your home, avoid using a sprayer near your metal roof. Overspray from the paint can land on the roof surface and cause unsightly stains or damage to the protective coating. Instead, use caution when painting and take measures to protect your metal roof from accidental contact with paint.

Don't Attempt Installation Yourself

Metal roof installation requires specialized knowledge, skills, and equipment to ensure proper installation and long-term performance. An example would be ensuring adequate space between panels to allow the roof to expand and contract based on temperature fluctuations. Attempting to install a metal roof yourself without the necessary expertise can lead to costly mistakes and compromises in the roof's integrity. Always hire a professional roofing contractor with experience in installing metal roofs to ensure a successful and durable installation.

Avoid Getting On Your Roof If You Feel Uneasy About It

Safety should always be a top priority when performing maintenance on your metal roof. If you feel uneasy or uncomfortable about getting on your roof, avoid doing so and instead, seek assistance from a qualified roofing professional. Attempting to work on your roof when you're not confident in your abilities can increase the risk of accidents and injuries.

Avoid Prolonged Neglect Of Your Roof

Neglecting routine maintenance can lead to accelerated deterioration of your metal roof, resulting in costly repairs or premature replacement. Avoiding regular inspections and maintenance tasks can allow minor issues to escalate into major problems over time. Stay proactive in caring for your metal roof to preserve its longevity and performance for years to come.

Frequently Asked Questions About Metal Roof Maintenance

Here are answers to some common questions about maintaining metal roofs:

What Kind Of Maintenance Is Needed On A Metal Roof?

Although metal roofs last longer than asphalt shingles, regular maintenance is still needed to keep them in optimal condition. These include:

• Regular inspections to identify any signs of damage, such as loose fasteners, dents, or rust spots.
• Cleaning gutters and drains to prevent water buildup and potential corrosion.
• Removing debris from valleys, dead spots, and other areas to prevent moisture buildup.
• Trimming overhanging branches and removing sticks or branches that may scratch or damage the roof surface.
• Checking for contact with other metals or materials to prevent galvanic corrosion.
• Inspecting for scratches, scuffs, chipping, flaking, or excessive chalking or fading, and addressing any issues promptly.

By performing these maintenance tasks regularly, you can ensure that your metal roof system remains in top condition and continues to provide reliable protection for your home or building.

How Often Should You Seal A Metal Roof?

Sealing a metal roof is generally not recommended, as it can void any existing warranty on the roof. Metal roofs are designed to be durable and withstand various weather conditions without the need for additional sealants. Applying sealant to a metal roof can interfere with its intended performance and longevity. Instead of sealing, regular inspections and maintenance are advised to ensure the roof remains in optimal condition. If there are concerns about the roof's integrity or signs of damage, it's best to consult with a professional who can provide guidance based on the specific type of metal roof and its installation.

Can You Pressure Wash A Metal Roof?

A hot pressure washer can be an effective tool for cleaning a metal roof, but it should be done with caution to avoid damaging the roof surface or causing leaks. When pressure washing a metal roof, use a low-pressure setting (less than 1500 psi) and a wide-angle spray to avoid denting or scratching the metal roof panels. Additionally, avoid spraying water upward under the roof panels, as this can force water underneath and lead to leaks. Before pressure washing, remove any debris or loose dirt from the roof surface, and use a mild detergent or specialized roof cleaner to help loosen stubborn stains.

Please be aware that if your roofing type is a standing seam metal roof, it's crucial to avoid using a pressure washer. Standing seam metal roofs are more delicate compared to corrugated metal roofs and can be easily damaged by high pressure. If you're unsure about pressure washing your metal roof, consider hiring a professional roofing contractor who has experience with metal roof maintenance.
