How Long Does Vinyl Siding Last?

Vinyl siding was introduced into the US back in the 1950’s as an alternative to aluminum. Back then, vinyl quality wasn’t as good as it is today. Vinyl is one of the most purchased siding options today and lasts 20-40 years.

Quality of Vinyl Siding

The material it’s made on plays a big role in the longevity of your vinyl siding. Not all vinyl is created equal, so it’s important to consult with a provider to evaluate the differences in siding options. If you buy cheap vinyl from big retailers, you may end up with cracking issues in a few years.

Vinyl siding is made primarily from polyvinyl chloride (PVC) resin and comprised of two layers (capstock and substrate). The function of the top layer is two-fold, aesthetics and weather protection. Thickness can vary from .035″ in cheaper grade siding products up to .052″ in the highest-grade products which vary from manufacturer to manufacturer. Today, the thinnest vinyl siding commonly used is .040″, and is known as “builder’s grade”.

What can I do to improve the life of my vinyl siding?

  • Have it installed by experts. Stapling or nailing incorrectly will have a direct impact on the life of your vinyl. Vinyl expands and contracts naturally, so there are special techniques used in installation.
  • Wash it once a year.
  • Be careful not to shoot rocks or debris at your home when mowing.
  • Surface-mounted fixtures, such as exterior lights, should not be mounted directly to vinyl siding. They should be mounted on mounting blocks instead, since fasteners penetrating the siding will restrict the siding’s natural expansion and contraction, causing problems.
  • Use corrosion-resistant fasteners.

What about vinyl siding warranties?

  • Prodigy siding and accessories are backed by lifetime, limited warranties* including fade protection, and are even transferable to the next owner of your home.
