When planning signage for your business, it’s natural to ask: how long do signs last? After all, you’re investing in a tool that works 24/7 to attract attention, guide customers, and reinforce your brand. The truth is, there’s no one-size-fits-all answer. The lifespan of signage depends on the materials used, where it’s installed, and how well it’s maintained. This guide breaks it all down to help you choose signage that stands the test of time.

The Role of Materials in Signage Lifespan

The material you choose will have the biggest impact on how long your signs last. Exterior signs need to withstand sun, rain, and wind, while indoor signs are protected from the elements and tend to last longer.

Acrylic signs, often used for indoor branding or lightboxes, are durable and offer a sleek, clean look. When kept indoors, they can last up to ten years or more with minimal fading.

Aluminium composite panels (ACP) are a common choice for outdoor signs. Lightweight and rust-resistant, ACP signage typically lasts five to seven years outdoors and longer if placed in a sheltered area.

Timber signage is ideal for rustic or eco-conscious branding, but it needs regular sealing or oiling to stay weather-resistant. Without maintenance, it may only last two to four years outdoors.

Vinyl wraps and graphics vary greatly. Basic vinyl may fade or peel within one to three years, but high-quality, UV-laminated vinyl can last up to five years on vehicles or windows.

LED illuminated signage can last 50,000 hours or more – that’s around five to six years of continuous use – but the casing and wiring may need earlier attention if exposed to the weather.

Understanding the strengths and weaknesses of each material will help you select the most suitable option for your signage needs and location.

Environment & Exposure Matter

Even the best materials won’t last forever if exposed to harsh conditions. In New Zealand, strong UV rays, salt air, heavy rainfall, and temperature shifts can all take a toll on your signage.

Signs facing direct sun will fade faster unless they are made with UV-resistant materials. If you’re based near the coast, salt corrosion can affect metal fixings or cause faster degradation of timber. High winds may rattle or loosen poorly secured signage, potentially leading to damage over time. That’s why it’s essential to consider not just what the sign is made of, but also where it will be located and how it will be installed.

Sheltered or shaded locations, or those facing away from prevailing winds, will extend the life of most signage types. A sign that lasts five years in one environment might only last two in another.

How Long Do Signs Last with Good Maintenance?

You might be surprised how much of a difference regular care can make. So, how long do signs last when you take care of them properly?

Cleaning your signage every few months removes dirt, salt, mould, and other grime that can break down materials. For vinyl, use a soft cloth and mild detergent to avoid damaging the print. For acrylic or aluminium, a simple wipe-down with warm, soapy water is often enough.

Timber signs need resealing or oiling at least once a year to prevent splitting or fading. Painted signs may need touch-ups over time, especially if exposed to the weather.

Fixings and brackets should also be checked regularly, particularly for signs that are elevated or on vehicles. A loose fitting can lead to rattling, warping, or damage in high winds.

If maintenance is kept up, your signage can last years longer than expected and continue looking sharp the whole time.

When Is It Time to Replace Your Signage?

Even with care, no sign lasts forever. The big question remains: how long do signs last before they need to be replaced?

Fading, cracking, or peeling is often the first sign it’s time for a refresh. Outdated branding or contact details are also strong indicators, even if the sign still appears fine. In some cases, changes to regulations (especially for health and safety signage) may require updates.

Vehicle wraps often need replacing after four to five years, especially if exposed to heavy driving or the sun. Exterior signs in exposed locations may need to be replaced every five to seven years, depending on the material and environmental conditions. Indoor signs can often go ten years or longer if they’re well-made and protected.

Staying on top of your signage helps keep your brand looking current and reliable.

Tips for Extending the Life of Your Signage

To make your signage last as long as possible, keep these points in mind:

• Choose materials suited to your location – if your sign will be outdoors, opt for UV-stable and weather-resistant options. 
• Schedule seasonal maintenance, especially before and after winter, to ensure your sign is well-maintained. 
• Clean signage gently and regularly to prevent the buildup of grime or mildew. 
• Use anti-graffiti coatings or protective films in high-risk areas to prevent vandalism. 
• Partner with a signwriter who understands the local environment and can recommend signage designed to last in your conditions. 

With a little foresight and care, you’ll get more value from every sign you install.

So, How Long Do Signs Last?

In summary, the lifespan of signs depends on three key factors: the materials used, the location of installation, and the level of maintenance. A sign made from quality materials, installed correctly, and cleaned regularly can last five to ten years or more. On the other hand, a cheap sign in a harsh location with no maintenance may only last a year or two at most. The better the planning upfront, the longer your signage will serve your business.
