Aluminum Siding: Common Myths and Misconceptions

Aluminum siding has a wide range of benefits, ranging from functional to aesthetic.

Strength and Durability

Aluminum siding is designed to withstand the elements in various climates, making it a versatile option for homeowners.

If you live in an area with fluctuating temperatures, aluminum is the perfect temperature-resistant material. Metal has a higher thermal conductivity than other materials, so it can withstand extreme hot and cold temperatures without warping.

Aluminum siding is also fire resistant, making it a top-performing choice in areas prone to wildfires. It has a high melting point, meaning your home will be better protected during potential fire hazards.

In addition, aluminum siding is resistant to pests, rust, moisture and rot — this increases its longevity compared to other materials, like wood, that are more susceptible to damage from these factors.

Ease of Installation and Maintenance

Unlike some siding materials, aluminum does not require extensive installation times or labor due to its lightweight qualities.

Aluminum also naturally resists dents and scratches, contributing to a low-maintenance exterior. It also has a protective polyester finish, which can help decrease maintenance costs over time.

Design Flexibility

Over the years, aluminum has evolved to cater to different tastes. While it can be used to achieve an industrial look, it’s become more versatile as it's now available in a range of colors and smooth or embossed finishes.

Eco-Friendly

While aluminum’s production process can have an environmental footprint, its recyclability allows it to be used over and over again.

Upfront Costs and Long-Term Savings

Compared to vinyl and wood, aluminum is very cost-effective. Depending on the type, the cost per square foot generally falls between $3 and $18. Plus, because it generally lasts for around 40 years, it’s a worthy investment.

It also has excellent insulating properties, especially when you use thicker gauges of aluminum, making it an energy-efficient choice that leads to lower utility bills and a more comfortable home.

Common Aluminum Siding Myths and Misconceptions

With an understanding of its benefits, you can debunk some of the common aluminum siding myths and misconceptions.

From concerns around paintability and durability to fire resistance and maintenance requirements, the truth may surprise you.

Myth #1: Aluminum Siding Causes WiFi and Cell Service Interference

Explanation of the Myth

One aluminum siding myth says that aluminum interferes with a home’s WiFi and cellular signals. Some people believe the metal surface acts as a barrier, weakening or blocking WiFi and cell phone signals completely.

The Truth

While it is true that metal surfaces can affect WiFi and cell signals, the level of interference is minimal. WiFi signals rely on radio waves, which can be affected by any type of wall or obstacle in your home.

The interference caused by aluminum siding is usually negligible, especially compared to other materials like concrete or steel. Modern routers and WiFi extenders can easily compensate for any slight disruption, ensuring a strong internet and cell phone connection.

If connectivity issues do happen to arise, there are some easy fixes such as relocating your router, using a range extender or switching to a different WiFi channel.

Myth #2: Aluminum Siding Is Easily Damaged by Hail or Weather

Explanation of the Myth

Another common aluminum siding myth is that it’s highly susceptible to hail damage and other extreme weather conditions. Some people think aluminum panels will dent, buckle or crack easily under hail or stormy weather.. This is far from the truth with modern aluminum construction.

The Truth

Aluminum, just like any siding, is not fully immune to damage. However, it is more durable and weather-resistant than many people think.

Modern aluminum siding is designed to withstand heavy rain, strong winds and even minor hail storms. Plus, coatings and treatments have advanced immensely, making aluminum more resistant to fading and corrosion than ever before.

With proper installation and regular maintenance, aluminum remains a tough and reliable option for your home.

Myth #3: Aluminum Siding Is Not Fire Resistant

Explanation of the Myth

People incorrectly assume aluminum siding is highly flammable — they believe that because it is metal, it conducts heat and could contribute to the spread of fire. However, that couldn’t be further from the truth.

The Truth

The reality is that aluminum siding is fire-resistant. It does not burn like wood or vinyl, and it can slow the spread of fire if it comes into contact with heat.

It will not catch fire, making it less of a fire hazard than other siding materials. Aluminum's reflective properties can even help deflect heat away from the home, potentially reducing the risk of heat-related damage.

Myth #4: Aluminum Siding Requires Constant Maintenance

Explanation of the Myth

Many homeowners believe that aluminum siding requires a lot of upkeep and maintenance. This myth suggests that aluminum needs frequent sealing and repainting, making it seem like a high-maintenance option. When compared to other materials, aluminum is exceedingly low maintenance.

The Truth

Unlike wood, which needs to be repainted and resealed regularly, aluminum siding retains its color and finishes much longer.

It does not warp or rot and is resistant to mold and mildew. While you still need to inspect and clean it over time to keep it looking fresh, aluminum does not need the constant attention that other materials do.

Maintenance Tips

Aluminum siding only needs occasional cleaning with a hose or power washer to remove any dirt or debris. Inspect for dents or peeling paint every few years. If repainting becomes necessary, aluminum siding holds paint well, so it can easily be refreshed every 5 to 10 years.

Myth #5: Aluminum Siding Is Noisy During Rain or Wind

Explanation of the Myth

Some homeowners falsely believe the sound of rain hitting or wind whipping around will cause a constant disturbance if they choose aluminum siding.

The Truth

Aluminum is a metal, and it can sometimes amplify sounds. However, the noise produced is minimal. The sound of rain or wind on aluminum is no louder than other materials like wood or vinyl.

Aluminum siding that is properly installed with secure fasteners and insulation further repels noise. In fact, most homeowners find they don’t notice any additional noise once their aluminum siding is in place.

Myth #6: Aluminum Siding Cannot Be Painted

Explanation of the Myth

Some homeowners believe that once aluminum siding is installed, they are stuck with the original industrial color for life. In reality, aluminum is extremely versatile to work with.

The Truth

Aluminum siding can be painted, and it’s one of the best materials to work with when you decide you want a color change.

When the surface is properly prepared with a cleaning and priming solution, aluminum holds paint extremely well. It can even be painted multiple times over its lifespan, giving homeowners the flexibility to update their homes as trends and preferences change with the times.

However, you should consult your siding manufacturer's warranty as painting or altering the surface could potentially void your siding's warranty
