7 Myths About Metal Roofing

If you’re asking “How long does a metal roof last?”, there are probably many things you’ve been told about metal roofing that aren’t true. One of them potentially being that they don’t last, or they rust and fall apart. Discovering the truth behind common misconceptions surrounding metal roofing is crucial for you considering this durable and versatile option. Despite its many benefits, myths persist, casting doubts on its suitability.

From concerns about noise and rust to misconceptions about cost and aesthetics, these myths often deter homeowners from exploring metal roofing. However, by debunking these misconceptions and providing accurate information, homeowners can make informed decisions about whether metal roofing is the right choice for their homes. As professional roofing contractors, we’ll address and dispel some of the most prevalent myths surrounding metal roofing. We will help to empower you to confidently consider this resilient roofing solution. So if you’ve asked the question ‘How long does a metal roof last?’, here are 7 myths you may have heard about metal roofing.

Myth #1: “Metal Roofs attract lightning”

You might be wondering, “Do metal roofs attract lightning?”. The answer is no, not any more than other roofing materials. The misconception that metal roofs attract lightning stems from a misunderstanding of how lightning behaves and interacts with different materials. While it’s true that metal is a conductor of electricity, this does not necessarily mean that metal roofs attract lightning strikes.

Lightning is a natural phenomenon that occurs when electrical imbalances build up within clouds and between the clouds and the ground. When lightning strikes, it typically seeks the path of least resistance to the ground, which may or may not include metal structures. Lightning is primarily drawn to the highest point in its vicinity, typically structures like trees, buildings, or other tall objects.

In reality, lightning strikes are random and unpredictable events that can occur on any type of surface, regardless of its material composition. While metal roofs may conduct electricity if struck by lightning, they do not inherently attract lightning strikes more than other roofing materials. Moreover, modern building codes and safety standards require metal roofs to be grounded to minimize the risk of electrical damage in the event of a lightning strike.

Ultimately, the likelihood of a lightning strike hitting a specific building depends on various factors, including geographic location, topography, and local weather patterns, rather than the type of roofing material used. Therefore, if this is the myth that leads you to ask “How long does a metal roof last?”, you have nothing to worry about. You shouldn’t base your roofing material choice solely on the misconception that metal roofs attract lightning.

Myth #2: “Metal Roofs are Noisy”

As a homeowner, you might have heard the myth that metal roofs are noisy, but let’s set the record straight. This misconception stems from outdated perceptions and incomplete understanding of modern roofing materials and installation techniques. Today’s metal roofs are engineered with advanced construction methods to significantly minimize noise issues.

When properly installed, metal roofs are placed over solid sheathing and insulation, serving as effective sound barriers. This setup dampens the impact of rain, hail, and other external disturbances, ensuring a quieter indoor environment. Additionally, modern metal roofing systems often incorporate features like textured surfaces and sound-absorbing materials, further reducing noise transmission.

Perhaps past experiences with older or improperly installed metal roofs contributed to this misconception. However, reputable roofing contractors now prioritize proper installation techniques to ensure optimal noise reduction and overall performance.

Are metal roofs louder than other roofing types? Generally, yes. But with proper roofing installation you can have a nice metal roof that won’t bring any noise concerns to your attention.

Rest assured, as a homeowner, you can enjoy the durability, longevity, and energy efficiency benefits of metal roofing without sacrificing comfort or peace of mind regarding noise levels. By debunking the myth of noisy metal roofs and highlighting the advancements in construction technology, you can confidently consider metal roofing as a quiet and reliable option for your home.

Myth #3: “Metal Roofs Rust Easily”

Let’s talk about the myth that metal roofs rust easily. It’s a common concern among homeowners considering this roofing option, but it’s important to understand the facts. High-quality metal roofing materials are specifically designed to resist rust and corrosion, ensuring long-lasting performance and durability.

Modern metal roofs are typically coated with corrosion-resistant finishes such as Conklin’s Metal Roof (MR) Coatings, which provide a protective barrier against moisture and environmental elements. These coatings effectively shield the metal from rust, even in harsh climates or coastal areas where exposure to salt air is a concern. Even more, these coatings can extend the lifespan of your roof for decades.

Furthermore, proper maintenance and care can further prevent rust formation on metal roofs. Simple tasks such as regular cleaning to remove debris and inspecting for any signs of damage can help homeowners identify and address potential issues before they escalate.

While it’s true that untreated metal may be susceptible to rust over time, reputable metal roofing manufacturers employ advanced coating technologies and quality control measures to ensure that their products withstand the test of time.

So, if you had been wondering “How long does a metal roof last?”, rest assured. With a properly installed and maintained metal roof, rust is not a concern you’ll need to lose sleep over. By choosing a high-quality metal roofing system and following recommended maintenance practices, you can enjoy the beauty and durability of metal roofing for years to come, without worrying about rust.

Myth #4: “Metal Roofs are Prone to Dents”

If you came here asking “How long does a metal roof last?”, then you may have heard this myth circling around.

Let’s dispel the myth that metal roofs are prone to dents, a concern that might make you hesitate when considering this roofing option for your home. While it’s true that metal roofs can dent under certain circumstances, such as large hail or falling debris, it also depends on the type of metal used on the roof.

Softer metals such as aluminum may dent easier, but they are still tougher over time than other materials such as your traditional shingles. Whilst shingles may not dent, their ability to withstand damage reduces over time due to its material properties. Alternatively, even softer metals such as aluminum will continue to withstand harsh weather events over decades.

On the other hand there are also thicker roof materials such as steel. Steel is much tougher than aluminum and won’t dent as easily. Again, if you’re wondering “How long does a metal roof last?”, a properly maintained metal roof will last much longer than an ordinary roofing system. Moreover, denting is not a significant issue to be concerned about when choosing your roofing system.

While no roofing material is completely impervious to damage, properly installed and maintained metal roofs offer excellent durability and protection against dents. By choosing a reputable roofing contractor and selecting a high-quality metal roofing system, you can enjoy the peace of mind that comes with knowing your roof is built to last and withstand the challenges of everyday life.

Myth #5: “Metal Roofs Are Expensive”

Let’s address the misconception that metal roofs are expensive, a belief that might deter you from considering this roofing option for your home. While it’s true that the upfront cost of metal roofing may be higher than some other materials, such as asphalt shingles, it’s essential to consider the long-term value and savings that metal roofs offer.

It’s no secret that metal roofs are more expensive initially. After thinking about the increase in initial price, you might have been led to ask “How long does a metal roof last?”. In all fairness, you must get your money’s worth when making a greater initial investment! 

Metal roofs are renowned for their durability and longevity, often lasting 50 years or more with minimal maintenance. In contrast, traditional roofing materials like asphalt shingles typically require replacement every 15-20 years, resulting in higher long-term costs associated with frequent repairs and replacements.

But… a longer lifespan isn’t the only reason to make the investment.

Moreover, metal roofs offer significant energy savings over time, thanks to their reflective properties that reduce heat absorption and keep your home cooler in hot weather. For example, when the Conklin Roofing System is applied, its solar reflective properties come into play. This system reflects the majority of the sun’s energy and significantly reducing the surface temperature to a mere 100°F. As a result, energy efficiency improves by an impressive 80%, which leads to approximately 30% savings on cooling costs.

Additionally, many insurance companies offer discounts for homes with metal roofs due to their resistance to fire, wind, and hail damage. These savings can help mitigate the upfront cost and make metal roofing a more financially viable option in the long run.

When considering the cost of a metal roof, it’s essential to factor in its durability, energy efficiency, and potential insurance savings, which can provide significant value over the life of your home. By investing in a high-quality metal roofing system, you’re not just purchasing a roof; you’re making a long-term investment in the comfort, safety, and value of your home.

Myth #6: “Metal Roofs Make Homes Hotter in the Summer”

Let’s debunk the myth that metal roofs make homes hotter in summer, a concern that may give you pause when considering this roofing option. In reality, metal roofs can help keep your home cooler by reflecting solar heat and reducing the amount of heat absorbed into your living space.

Unlike traditional roofing materials like asphalt shingles, which can absorb and retain heat, metal roofs are designed with reflective coatings that bounce sunlight away from your home. This reflective property helps to maintain lower roof temperatures and minimize heat transfer into your attic and living areas.

Furthermore, many metal roofing systems are installed with airspace between the metal panels and the roof deck, acting as insulation to further reduce heat transmission. This helps to create a barrier against heat gain and keeps your home more comfortable during hot summer months.

It’s important to note that the color of your metal roof can also impact its heat reflective properties, with lighter colors typically offering greater reflectivity and heat reduction compared to darker hues.

By choosing a high-quality metal roofing system and selecting the appropriate color and finish, you can enjoy a cooler, more energy-efficient home without sacrificing style or durability. With metal roofing, you can beat the heat and enjoy year-round comfort in your living space.

Myth #7: “Metal Roofs are Prone to Leaks”

Let’s address the myth that metal roofs are prone to leaks, a concern that might make you hesitant to choose this roofing option for your home.

You may have heard of people with metal roofs that experience leaks, or your own metal roofing system might have a leak. Rest assured, this isn’t a fault in metal roofing, but some metal roofing systems are outdated. Modern engineering has created roofing systems such as Conklin’s Metal Roofing (MR) system that prevent leaks and sustain the life of your metal roof for several decades. In reality, properly installed and maintained metal roofs are highly resistant to leaks, offering reliable protection against water infiltration and ensuring a dry and secure interior.

One of the key factors contributing to the leak resistance of metal roofs is their interlocking panel design and concealed fasteners, which create a seamless and watertight barrier against moisture. Unlike traditional roofing materials like asphalt shingles, which rely on overlapping layers and exposed nails, metal roofs are installed with precision to minimize the risk of water penetration.

Additionally, metal roofing systems are engineered with durable materials such as steel, aluminum, or copper, which are naturally resistant to corrosion and degradation. When coupled with protective coatings and sealants, these materials provide long-lasting performance and peace of mind, even in harsh weather conditions.

Routine maintenance, such as inspecting for damaged or loose panels and clearing debris from gutters and drainage systems, can further enhance the leak resistance of your metal roof. By investing in a high-quality metal roofing system and partnering with a reputable roofing contractor for installation and maintenance, you can enjoy the confidence of knowing that your home is protected from leaks for years to come.
