How Long Does Vinyl Siding Last?

To put it simply, vinyl siding lasts a long time. Depending on the quality of the materials and the experience of the contractor that installs it, it can last about 60 years. And with some minimal maintenance on occasion, your vinyl siding can last even longer than that.


It has several things going for it that other siding materials, such as wood, aluminum, fiber cement, or stucco can’t compete with. Vinyl siding is durable, energy-efficient, resistant to weather, and is cost-efficient. And when it comes to its average lifespan, no other siding material comes close.


What Is Vinyl Siding?


The material consists of two layers, the top layer (capstock) and the underlying layer (substrate). These are made primarily out of polyvinyl chloride and resin. The top layer also contains titanium dioxide, which provides both coloration and UV-light protection. Vinyl siding comes in a wide array of colors and designs, perfectly able to mimic other siding materials. The substrate, on the other hand, also contains limestone, which facilitates manufacturing and reduces overall costs.


Why Does Vinyl Siding Last This Long?


There are several reasons why and how it manages to last so long. Aside from the materials that make it, we can also include the following:


  • It resists the elements
  • It’s not susceptible to moisture or insects
  • It won’t rot or warp
  • Increased durability
  • It’s easy to maintain
