How Long Do Commercial Signs Last?

Ask ten sign shops how long a sign lasts and you will hear ten round numbers. The honest answer is that a sign is a set of parts, and each part ages at its own speed. The aluminum cabinet may last for decades. The vinyl on the face may need replacing much sooner. The LED power supply sits somewhere in between.

Gogi Signs builds signs for businesses across New Jersey and New York City. This guide gives you the manufacturer ratings for each part, explains what those ratings mean and shows what makes a sign last longer in our weather.

In this guide

Ratings Are Not Warranties

Material makers publish durability ratings. These tell you how long a product is expected to perform under set test conditions. They are not promises. Avery Dennison says plainly that its durability figure is not a warranty, on its 900 Supercast data sheet. 3M describes the 7 year life of its 3630 film as an expected, unwarranted figure, in its product bulletin. Warranties are separate documents with their own terms. Pixel Wraps, our sister graphics shop, explains the same point for wraps in how long commercial vehicle wraps last.

Calendered vinyl	Up to 6 years	ORACAL 651
Cast vinyl	7 to 8 years	ORACAL 751
Premium cast vinyl	8 to 10 years	ORACAL 951
Premium cast vinyl	Up to 10 to 12 years	Avery 900
Translucent face film	Up to 8 years, colors	ORACAL 8800
Sign grade acrylic	30 year yellowing warranty	ACRYLITE
LED modules	120 months or life of sign	Sloan warranties
LED power supplies	60 to 120 months	Sloan warranties

Vinyl Graphics

Vinyl is usually the first part of a sign to show age. ORAFOL rates its calendered ORACAL 651 for up to 6 years, its cast ORACAL 751 for 7 to 8 years and its premium cast ORACAL 951 for 8 to 10 years, depending on color. Avery Dennison rates its 900 Supercast for up to 10 years in colors and 12 in black and white. These figures are for vertical surfaces in a mild climate. Metallic and some bright colors are rated for less.

Lit faces use translucent film. ORAFOL rates its 8800 translucent film for 8 years in colors in its mildest zone and 6 in the next zone. Horizontal and angled surfaces always get less life, because they take more sun and hold water.

Faces and lighting age faster than the letters themselves

Sign Faces

Sign grade acrylic is the most common face for lit signs. ACRYLITE offers a 30 year warranty against yellowing on its LED sign grades, according to its sign products page. Polycarbonate faces are tougher but can yellow over time, as noted in Retail and Restaurant Facility Business. A cracked face is usually from impact or from a frame that does not let the acrylic expand and contract. Our guide to the best outdoor sign materials explains why that movement matters.

LED Lighting

LEDs rarely burn out like a bulb. They dim. ENERGY STAR explains that LED lifetime is based on when light output drops by 30 percent, in its LED lighting guide. Warranties tell you more about which part fails first. Principal Sloan’s limited warranty lists 120 month coverage for several sign modules and 60 to 120 months for power supplies. SloanLED’s global warranty covers some module lines for 120 months or the life of the sign, and most power supplies for 60 months.

In practice, a lit sign that goes dark all at once usually needs a new power supply, not a new sign. Our sign repair team handles that. Our sister company in New York covers lit letters in more detail in its channel letter signs guide.

Printed panels last longest with the right film and laminate

Cabinets, Letters and Panels

The structure is usually the longest lasting part. Aluminum does not rust, and carved HDU absorbs almost no water, with one maker listing water absorption of 0.02 percent by volume on its data sheet. These parts often outlast several faces and lighting systems, as long as seams stay sealed and hardware stays sound. That is why a face swap or LED conversion can give a sound sign many more years.

Aluminum does not rust, which helps a sign last

What This Means by Sign Type

Owners often want the name, services, phone number, website and a slogan on the main sign. Drivers read a few words at most. The FedEx Office survey found that consumers expect a small business to have two or three signs around its storefront, not one sign carrying everything. The fix: keep the main sign to your name and what you do, and move the details to your windows, door and a blade sign. Pixel Wraps, our sister graphics shop, covers window graphics that carry the details well.

Channel letters. The aluminum letters last a long time. Expect to service the faces, vinyl and power supplies over the years. See our channel letters.
Light boxes. The cabinet often outlasts several faces. A new face on a sound cabinet is a common refresh. See our light box signs.
Dimensional letters. Unlit metal and acrylic letters have no lighting to wear out, so finish and mounting decide their life.
Printed panels. The film and laminate decide the life. Cast film on aluminum composite lasts much longer than calendered film.
Carved and painted signs. Paint is the part that needs care. A repaint can bring an old carved sign back.

What Shortens the Life of a Sign

Most of these are in your control at the design stage

Strong sun. South and west facing signs fade faster.
Angle. Horizontal and angled surfaces get less life than vertical ones.
Salt. Within five to ten miles of salt water, and near salted roads, metal corrodes faster, according to the stainless steel handbook.
Water. Unsealed seams and blocked drain holes let water into cabinets and letters.
Cheap materials. Calendered vinyl and low grade plastics on a permanent sign.
Skipped maintenance. Dirt, nests and loose hardware all speed up wear.

Our Weather Is Part of the Equation

New Jersey and NYC signs face a lot. Northern New Jersey averages 40 to 50 inches of snow a year, according to the New Jersey State Climatologist. In Central Park, the average January high is above freezing and the average low is below it, according to the National Weather Service, so water in joints freezes and thaws all winter. Signs built for that, with sealed seams, the right alloys and stainless hardware, last much longer than signs built for a mild climate.

Metal finishes change with weather, so choose coatings with care

Common Questions About Sign Lifespan

How long does a business sign last?

It depends on the parts. Aluminum structures can last for decades, while vinyl is rated for about 6 to 12 years depending on the grade, and LED power supplies usually carry 5 to 10 year warranties.

How long do channel letters last?

The aluminum letters themselves can last many years. Faces, vinyl and lighting usually need attention sooner, and can be replaced without replacing the letters.

How long does outdoor vinyl last?

Calendered ORACAL 651 is rated up to 6 years, and cast films such as ORACAL 951 and Avery 900 are rated 8 to 12 years on vertical surfaces in a mild climate.

Is a durability rating a warranty?

No. Avery Dennison and 3M both say their durability figures are not warranties. Warranties are separate documents with their own terms.

What shortens the life of a sign?

Strong sun, horizontal surfaces, salt, water in seams, cheap materials, poor installation and skipped maintenance.

How can I make my sign last longer?

Choose quality materials, use stainless hardware near salt, keep water out, clean gently and have the sign inspected once a year.
