Hardie Board siding lasts 30–50 years with proper care, outperforming most options and matching or surpassing the lifespan of quality wood. Fiber cement resists rot, insects, fire, and weather, with many 1990s homes still looking great, supporting its durability. James Hardie offers a 30-year limited warranty and a 15-year warranty on ColorPlus finishes.

Hardie Board siding costs more upfront than vinyl, which typically ranges from $3–$12 per square foot, while Hardie Board ranges from $11–$57. The price difference can mean thousands of extra dollars initially. However, over 30–50 years, Hardie often proves cheaper due to its durability, lower maintenance, higher resale value, and fire resistance. Vinyl needs replacement every 15–25 years and requires minimal upkeep, but Hardie Board’s longer lifespan and added benefits often make it more economical overall.

Hardie Board siding is more costly and complex to install than vinyl, requiring specialized tools and skilled contractors, as well as careful dust management due to silica exposure. The process extends timelines, raises costs, and is weather-dependent. Although durable, damages often require professional repairs, and the material’s rigidity can cause cracking under severe impacts or settlement.
