How Long Does Vinyl Siding Last – Guide to Siding Lifespan

Vinyl siding is a popular choice for new home builds or for homeowners looking to refresh and increase their curb appeal.

With a range of available colour options, quality, and durable materials, vinyl siding is a cost-effective way to keep your home both protected and looking its finest.

But what is the lifespan of vinyl siding? Will it last for years or will you be looking for a replacement after the first cold snap or windstorm?

The good news is that vinyl siding is an investment that will still be paying dividends years down the road.

Here’s a quick look at vinyl siding, its benefits, and how long you can expect it to last!

How Long Does Vinyl Siding Last?

On average, vinyl siding can last 20 to 40 years. In some instances, the siding can last for up to 60 years!

No matter how you look at it, vinyl siding will last you decades. The number of decades, however, is impacted by a number of factors.

Vinyl siding life expectancy depends on:

  • The quality of the materials. The grade, or thickness, of the vinyl siding, will impact its lifespan. While it is more expensive, thicker siding can last longer. No two installs will be the same so speak with a professional and determine what is right for your home before you make the siding investment.
  • How well it is installed. Professional installation is a must if you are hoping to get a long life out of your vinyl siding. Proper installation, coupled with the use of the right tools and materials will make the siding more durable. This process may mean repairing water damage, or other types of damage before the siding goes on.
  • How well the vinyl siding is maintained. Fortunately, vinyl siding maintenance is fairly easy. It involves cleaning your vinyl siding as often as it needs and regularly checking for signs of damage. Remember, it is always easier (and cheaper!) to repair small damages than it is to fix a larger problem.
  • Weather conditions. Extreme weather conditions can wreak havoc on your home’s exterior. High winds, hail, and other weather events can puncture your siding or otherwise compromise its integrity. Extremely high temperatures can lead to warping, while too much sun exposure may cause colour fading. Always check your vinyl siding following extreme weather events and look for signs of damage each time you perform maintenance. Replace any damaged or broken panels as soon as possible. This will prevent water and pest damage to your home.

What Is Vinyl Siding?

Since its initial introduction in the 1950s, vinyl siding has emerged as one of the most durable types of siding available. Where it used to break, buckle, and fade, it is now made from superior materials and stands up against even the harshest Ontario winters.

But what makes it so durable? What is vinyl siding made from?

Vinyl siding is comprised of two layers, the capstock, or top layer, and the substrate, or bottom layer. These layers are made from polyvinyl chloride and resin.

The top layer will also contain titanium dioxide which will provide UV-light protection and protect against discolouration. The bottom layer contains limestone, increasing its strength and durability.

Reasons Vinyl Siding Lasts so Long

Aside from the strength of manufacturing materials, there are a few reasons why vinyl siding lasts as long as it does.

Here’s a look at just a few reasons for the long lifespan of vinyl siding.

Resistant to Moisture

First and foremost, vinyl siding is resistant to moisture. This is beneficial in a few different ways.

Moisture resistance means that your vinyl siding is unlikely to warp or rot. This will not only keep it looking new but will also eliminate the risks of mould growth and insect infestation.

When siding absorbs moisture, it can expand, creating space for water to seep in, which, aside from potential mould growth, can do damage to your home’s building materials, creating a large and expensive problem.

With vinyl siding, water rolls right off the panels, saving you a world of trouble.

Cleaning Vinyl Siding

Easy to Clean & Maintain

One of the best features of vinyl siding is just how easy it is to clean and maintain.

Cleaning your vinyl siding is as simple as using a vinegar and water solution along with a broom, soft-bristled brush, or soft cloth. Simply apply the solution and then wipe it off. This type of cleaning really only needs to be done once or twice a year!

Some people want to use pressure washers to get rid of built-up grime but these washers may cause damage to the siding so always consult your manufacturer before you choose this option.

Maintenance is as simple as doing a spot check every now and then. Take a walk around the property after extreme weather or when the seasons change. Report any possible signs of trouble, like cracks, to your home exterior experts and they can come out to assess and perform repairs as needed.

Extreme Weather Durability

When it comes to taking a beating from the elements, vinyl siding is the most durable option.

Vinyl siding will not fade with exposure to UV light and extreme heat and cold will not cause it to buckle or crack.

Given harsh Eastern Ontario winters, your home needs something that can stand up to ice, sleet, hail, and strong winds. Vinyl siding can do just that.

Having siding you can trust means that your exterior insulation will remain protected and your home will operate more efficiently, reducing your heating and cooling costs.
