Metal Siding Pros and Cons

Your siding needs to not only be functional—serving as your home’s protective shield and insulator—but should boost your house’s curb appeal. Many people might think of cold, silver slabs when they picture metal siding, but this material has come a long way. Now that its available in a range of colors and styles—sometimes even mimicking wood grain—it’s worth considering it as an option for your home. Review the pros and cons of metal siding and see if it’s the best siding choice for you.

What is Metal Siding?

Metal siding is a siding option made from metal panels that cover the exterior of a residential or commercial building. Sometimes called wall cladding, metal siding is often made from steel but can be produced with copper, zinc, or aluminum. 

Metal siding first became available in the 1940s, but the metallic look was not popular with many homeowners. Fast forward to the 1980s when manufacturers started experimenting with embossed coatings, thus creating a wider range of looks—including ones that mimic wood grain—available, boosting metal siding’s appeal. Most metal siding produced today looks identical to vinyl siding—you might not be able to tell one from the other unless you were very close. 

Pros of Metal Siding

Let’s look at why metal siding is becoming an increasingly popular choice among homeowners.

1. Low Maintenance

Metal siding doesn’t absorb heat or moisture, making it very low maintenance. Most homeowners install it and clean it once a year without any other issues to worry about. Compare that to wood, which can rot, warp, or become a home to pests.

2. Durability

Metal is one of the strongest siding materials available. It can withstand all kinds of extreme weather, temperature shifts, and high winds. You can even purchase 53-gauge metal, which is even stronger than the standard 44-gauge metal siding.

3. Energy Efficient

Metal reflects the sun’s rays away from your home, keeping your home cool in summer and saving you money on your summer energy bill. 

4. Pest Resistant

Many homeowners with metal siding don’t need to spray for termites and other creepy crawlies. Pests are not drawn to metal siding as they are to other materials—they can’t eat it or tunnel through it to build nests.

5. Environmentally-Friendly

Steel and aluminum are two of the most recycled materials out there, so if you look for recycled siding, you won’t be contributing to any ecological imprint caused by new manufacturing. In addition, metal siding lasts a long time—40–70 years—and can be recycled again once you’re ready to replace it.

6. Fire-Resistant

If you live somewhere prone to wildfires, metal siding could be an excellent option. The material is non-combustible and doesn’t catch fire easily, offering you superior protection and giving you peace of mind.

7. Aesthetics

Over the decades, metal siding options have exploded. You can now buy metal siding in different styles and colors, some resembling wood grain.

8. Soundproofing Ability

Because metal siding is thicker than other siding materials, it’s inherently more soundproof, which comes in handy if you live in an urban neighborhood with lots of street traffic. You can also opt to insulate your siding to give it even more sound and temperature resistance.

Cons of Metal Siding

Nothing is perfect. Here are the cons to metal siding, which you should consider carefully before committing to it for your home.

1.  Expensive

The cost of metal siding varies based on the type of metal you choose, but most of the more durable types will be more expensive than vinyl, stucco, or in some cases, wood. Expect to spend $4 to $16 per square foot for steel siding or $3 to $18 per square foot for aluminum, excluding labor fees. 

2. Prone to Dents

While metal is very durable, it can still be dented by heavy objects, so it wouldn’t be a great option if your nephew loves to play catch and hasn’t quite nailed his hand-eye coordination. Sharp or pointy objects can also scratch metal siding.

3. Rust Risk

If you live near the ocean, you should know that some metal siding—when exposed to humid, salty air—can rust. There are some metals that are approved for use if you live near the water, such as copper, stainless steel, and zinc.

4. Difficult to Install

Because metal is heavier than some other siding materials and thus more difficult to cut, it can be a pain to install. DIYers might want to hire a professional metal siding installer to take care of it.

Alternatives to Metal Siding

When deciding whether metal siding is right for your home, consider the other siding material options on the market, such as:

• Fiber cement: Strong and durable, fiber cement siding can last between 30 and 50 years, but does require repainting every 10 years.

• Stucco: Another durable option, stucco can last up to 100 years. Unfortunately, its porous nature can absorb water, causing it to crack over time. It is also very difficult to install.

• Vinyl: One of the most affordable siding options, vinyl can cost as low as $2 per square foot. It is less durable than many other siding options, though, and can crack in extreme cold or melt in extreme heat. 

• Wood: Everyone loves the organic, rustic look of wood, but it is susceptible to water damage and termites. It is resilient in many different temperatures, however, and depending on your manufacturer, can come from a sustainable source.

Is Metal Siding Right for You?

Metal siding might be an excellent choice if you need a durable, low-maintenance siding option. Because it is now available in a wide range of colors and styles, it suits many design preferences and is fire-resistant—a desirable trait if you live in a forested area with hot, dry summers. That said, it requires a higher upfront cost than vinyl and is difficult to install on your own—you’ll need to factor in the cost of professional installation.
