In this post, you’ll find out all you need to know about the lifespan of a shed and what steps you can take to ensure its life is a long and useful one.

How Long Does a Shed Last?

It’s difficult to give an exact figure for how long sheds last because many factors can affect its lifespan. However, in general terms, you can expect the following, for the most common types of shed material:

  • Wooden sheds such as those used for wood storage: Between 20 and 25 years

  • Vinyl sheds: Between 25 and 30+ years

  • Resin or plastic sheds: Between 5 and 7 years

  • Metal sheds: Less than 5 years

These figures are merely ballpark figures. Next, let’s look at some of the things that can impact the lifespan of your shed.

What are the Factors That Influence the Lifespan of a Shed?

Whatever type of shed you purchase, there are several things that can increase the lifespan of your shed.

Quality Workmanship

Any shed is only as good as the workmanship that has gone into building it. The first step in purchasing a shed that’s going to last is finding the right shed-building team.

Ideally, you want to look for a builder that’s got a good reputation, both in terms of shed style, type and construction. You also need to make sure they use the highest quality materials, even if you only need it for wood storage.

Check whether there is a portfolio of work you can look at and maybe ask around your neighborhood, friends, family, and colleagues to see if anyone can recommend a competent shed builder.

Something else to look for is a workmanship warranty that will cover any issues that might arise following the installation of your shed.

Urban Sheds is a reputable company that takes pride in designing a quality shed and ensuring an expert builder is available to make your dream come to life.

Following the design process, using its free, unique 3D shed modeling software, you’re connected with a local builder who will be able to build your high quality shed onsite. The builders follow Urban Sheds structural guidelines, use high quality materials and each outdoor shed comes with a 30 year structural warranty.

Position it Correctly

You might not realize that positioning is everything when it comes to the lifespan of your shed. More than aesthetics should be considered when deciding where your shed should be located.

As well as finding a place where the shed looks good, you should also place it where it protected and less vulnerable to the ravages of heavy rains and high winds.

If you live in an area that experiences heavy snowfall, you should place your wooden sheds where they're not going to take on extra snowfall from surrounding vegetation and trees.

Strength of the Frame

Storage sheds that are well built should last for more than a few years. Many are designed and built to last for decades. Whichever type of storage sheds you use, don’t look at it as merely a temporary structure because it should be so much more than that.

A sturdy frame is a vital component of storage sheds that is going to be standing for more than a few years. The best base for your storage sheds longevity is one that’s made using concrete blocks. Any floor joists should be pressure-treated so that they are decay- and pest-resistant.

Correct Sealant

Water doesn’t have to be the enemy if you’ve opted for a wooden shed. What is the enemy, however, is water exposure that’s prolonged.

The key to making wooden sheds last the test of time is to use the proper sealant. Extreme outdoor elements can be a massive test for a portable buildings durability because wood expands and contracts when it absorbs moisture.

If wooden sheds are sealed correctly, it will act as protection from the worst the weather can throw at it.

When your wooden shed is first installed, the weather might be sunshine and rainbows, but the aim should be for your shed to withstand all the elements, including subzero temperatures and torrential rain.

Paint Finish

Paint can be another way of protecting your shed from the elements and keep it in tip-top shape. Depending on where your shed is positioned, you may need to repaint it from time to time.

For sheds that are exposed to direct sunlight, be prepared to get out the paint every 10 years. Sheds that are in the shade and therefore protected from direct sunlight, might not need repainting so frequently.

Painting and repainting is one of the most effective ways to help your shed last longer. Don’t forget to use high-quality paint as well, because that will make a significant difference.

Timely Repairs

If you notice there’s a problem with your shed, don’t put off until tomorrow what you can do today. However large or small the problem, time will be of the essence. Most shed issues won’t take a lot to fix, however, the longer you leave it, the worse it will get.

Regularly inspect your shed for signs of damage and act promptly if there’s anything that concerns you. It’s likely the problem won’t be catastrophic, unless you fail to take action.

Regular Maintenance

A shed requires regular maintenance if you want it to give you decades of enjoyment. Performing regular, simple maintenance is far more affordable and less time-consuming that repairing a broken or damaged shed. All it takes is a spare few minutes once a week. Consider adding the following to your shed maintenance schedule:

  • Clean the interior and exterior walls

  • Quickly examine for warping or cracks

  • Trim the grass around the edge of your shed

  • Remove anything that’s leaning up against your shed

  • Look for signs of critters and any other unwelcome guests
