5 common myths and misconceptions about metal roofs

Myth #1: Metal roofs make a lot of noise during rainfalls and storms

One of the most prevalent myths about metal roofs is that they make a lot of noise during rainfall. This myth likely stems from the fact that tin roofs were once popular and known for being loud during rainstorms. Although this might have been the case a century ago or for metal roofs on barns, it no longer applies today. Modern metal roofing materials have come a long way and now offer noise-reducing properties.

The noise levels from metal roofing depend significantly on the type of metal and installation method. Adding padding between the metal and plywood decking can significantly reduce unwanted sounds, ensuring a quieter environment. Rest assured, you can have a peaceful sleep without being disturbed by the sound of rain amidst thunderstorms.

Uncoated aluminum or corrugated metal sheets, common in barns or sheds, may produce louder noise during rainfall due to reverberation. A metal roofing panel with a thicker coating and texture effectively disrupts sound wave reverberation. Be sure to consult with your contractor on the best type of metal and installation method to reduce noise levels.

Myth #2: Metal roofs attract lightning

It’s a common belief that metal is an excellent conductor of electricity, leading many to assume that metal roofs are more likely to attract lightning strikes. The idea of having a lightning rod above your head is quite scary. However, it’s just that – an idea. The truth is metal roofing does not increase the chances of a home being struck by lightning.

Metal conducts electricity, but it doesn’t attract it. Studies on lightning protection indicate that metal roofing is as unlikely to attract a lightning strike as any conventional roofing material. 

However, the truth is that your home’s height, location, and surrounding trees significantly influence the likelihood of lightning strikes. Metal roofing provides no additional risk compared to other roofing materials.

In fact, metal roofs are considered safer during lightning storms. Due to their non-combustible nature, metal roofs do not catch fire. They can also dissipate the electric charge quickly without causing any damage to your home’s electrical system.

Myth #3: Metal roofs are expensive

It’s not true that metal roofs are often considered luxurious and out of reach for many due to their perceived high cost. While it’s true that metal roofs may have a higher upfront cost, they offer long-term savings that can make them more affordable than traditional roofing materials in the long run. That said, the cost of metal roofs can range from $120 to $900 per 100 square feet based on the materials and regions.

Metal roofing is highly durable and can last 50+ years with proper maintenance, while other roofing materials may need replacing every 20-30 years.

Moreover, metal roofs are energy-efficient, reflecting heat from the sun and reducing cooling costs in the summer. This can save homeowners significant amounts on their energy bills over time. Additionally, metal roofs require minimal maintenance and are less susceptible to damage from weather conditions, reducing repair and replacement costs.

Myth #4: Metal roofs are prone to rust and corrosion

Some people believe that metal roofs will rust and corrode over time, leaving homeowners with an unattractive and damaged roof. While this could be true for some types of metal, such as untreated steel or iron, it is not true for modern metal roofing materials.

Most metal roofs are made from corrosion-resistant materials such as aluminum, zinc, or galvanized steel and are coated with protective layers to prevent rust and corrosion. With proper maintenance, a metal roof can last for decades without any signs of rust or corrosion.

Additionally, if you live in a coastal area where saltwater is prevalent, your roofing contractor can apply an additional coating to further protect your metal roof from the corrosive effects of saltwater.

Myth #5: Metal roofs are too heavy for my house

Actually, metal roofs are much lighter than conventional roofing materials like tile, slate, or concrete. Metal roofing typically weighs between 50 and 150 pounds per 100 square feet, while other materials can weigh upwards of 750 pounds per 100 square feet. 

Take singles, for example. Shingles can range from 200 pounds per square for basic shingles to 500 pounds per square for premium shingles. Many homeowners add new shingles over existing ones without much consideration, increasing the weight of their roofs. If your roof can handle the weight of shingles, it can undoubtedly support the weight of a metal roof easily.

This weight difference means a metal roof can be installed on most homes without additional structural support. In fact, in many cases, metal roofing can be installed over an existing roof, eliminating the need for a complete tear-off and reducing installation time and costs.

Additionally, the lighter weight of metal roofing also puts less stress on your home’s foundation and supports, potentially extending their lifespan.  So don’t let the fear of a heavy roof hold you back from considering a metal roof for your home. Its weight is just one of the many benefits it offers.  

If you’re in the market for a new roof, don’t let these common myths about metal roofing stop you from considering it a viable option. With its durability, energy efficiency, and long-term cost savings, a metal roof could be the best choice for your home.
