Siding Showdown: Fiber Cement vs Aluminum

When renovating or building a home, choosing the right siding material is a critical decision that impacts your home’s aesthetic appeal, durability, and maintenance requirements. Two popular choices in the siding industry are fiber cement and aluminum. Here, we explore how each material stands up in terms of curb appeal, longevity, maintenance, and return on investment.

Curb Appeal: Enhancing Your Home’s Exterior

The exterior of your home is the first thing people notice, making curb appeal extremely important. Aluminum siding has been a traditional favorite due to its cost-effectiveness and variety of color options. However, it lacks the texture and depth offered by more modern materials.

Fiber cement siding, particularly the Hardie Board, offers a superior aesthetic with its ability to mimic other materials like wood. This versatility allows homeowners to achieve a desired look without compromising on durability. The availability of pre-primed boards that can be painted any color further enhances its appeal, providing a custom look that can match any home design.

Durability: Long-Term Performance

Both aluminum and fiber cement are known for their durability. Aluminum is lightweight, rust-resistant, and does not succumb to rot. However, it can dent easily and may fade over time. On the other hand, fiber cement is renowned for its robustness against severe weather conditions, making it an ideal choice for areas with harsh climates.

Fiber cement’s composition of cement, sand, and cellulose fibers contributes to its sturdiness and longevity. Innovations such as Hardie’s HZ5 product line are engineered to withstand freezing temperatures and moisture, ensuring that the siding not only lasts longer but also maintains its aesthetic value over the years.

Maintenance: Ease of Upkeep

In terms of maintenance, aluminum siding offers a “set it and forget it” solution, requiring little more than regular cleaning to maintain its appearance. Despite its resilience, the potential for dents and fading can necessitate additional upkeep or replacement panels.

Fiber cement siding scores high on the maintenance scale thanks to technologies like Hardie’s ColorPlus, which offers a vibrant, baked-on color that is warrantied for up to 15 years. After the warranty period, a simple repaint can refresh its appearance. Regular cleaning and occasional caulking are all it takes to keep fiber cement siding looking new.

Investment: Maximizing Home Value

Considering the financial aspect, aluminum siding generally costs less upfront and can last between 30-40 years. However, its susceptibility to damage and the potential for aesthetic degradation can diminish its long-term value.

Fiber cement siding, while initially more expensive, proves to be a worthwhile investment due to its durability and minimal maintenance requirements. Hardie Board is not only warrantied for up to 30 years but can last even longer, resisting common issues like denting and cracking. This makes it highly attractive to potential buyers, often increasing the resale value of the home.


For homeowners seeking a balance of style, durability, and value, fiber cement siding clearly outperforms aluminum. Its ability to enhance curb appeal, coupled with its robust construction and low maintenance needs, provides a compelling case for its selection.
