How Long Do Outdoor Signs Last?

A 10 x 14 inch .040 aluminum sign is $59.99; it will not rust and carries a 5+ year outdoor durability guarantee, the longest life we state on a rigid sign. An 18 x 24 inch coroplast yard sign is $64.99, built for temporary outdoor jobs. Both are printed in the USA and ship for a flat $10.

Outdoor sign life depends on the material: a .040 aluminum sign is guaranteed for 5+ years outdoors, 3 mm ACM is weatherproof and made for permanent signs, and coroplast, PVC and vinyl banners are built for temporary outdoor jobs that run weeks to months. Foam board does not belong outside at all.

We only state a year count where we can stand behind it, and that is the aluminum guarantee. For the other materials, the table below gives what we state about each one and the job length it is built for.

Material, what we state, and what it is built for Starting price
Aluminum, .040 in: will not rust, 5+ year outdoor durability guarantee. Built for years: parking, address, gate signs 10 x 14 in, $59.99

Coroplast, 4 mm: rated for outdoor use. Built for weeks to months: yard, campaign, job site 18 x 24 in, $64.99
PVC, 1/8 in: water resistant, short term outdoor use. Short outdoor jobs, long term indoors 6 x 24 in, $64.99
Vinyl banner, 13 oz: weather resistant and UV safe. Events, promotions, seasons From $64.19

How Much Does a Long Lasting Outdoor Sign Cost?

A long lasting outdoor sign starts at $59.99 for a 10 x 14 inch aluminum panel. The aluminum product page opens on its 12 x 18 inch size, and this is the sentence it prints: A 12" x 18" Aluminum Sign is $74.89. Artwork prep is $14.99 per item. Printed in the USA in 3 business days and shipped nationwide, flat $10 shipping to any US address.

A temporary outdoor sign is priced the same way, by size, and its page prints this sentence: An 18" x 24" 4mm Coroplast Standard Yard Sign is $64.99. 2 signs are $74.99, which is about $37.50 a sign. Artwork prep is $14.99 per item. Printed in the USA the next business day and shipped nationwide, flat $10 shipping to any US address.

Spending on the right material once usually beats reprinting a temporary sign several times. A sign that has to stand for two years is an aluminum or ACM job from the start. AI image to print makes your file print ready for $14.99 per item, and Design it for me is $29.99 with two revisions, free on an item of $499 or more.

How Long Does a Coroplast Sign Last Outside?

A coroplast sign lasts for the length of a typical temporary job: a home listing, a campaign season, a construction project or an event series. It is 4 mm corrugated plastic, UV printed, rated for outdoor use, and it shrugs off rain. We do not put a year count on it.

What shortens it is time in sun and wind. Over a long stretch, the sheet can bow, the bottom edge can scuff on the stake, and pale colors can look tired next to a fresh sign. A sign that comes down after a month never reaches that point; a sign left up for years does.

That is the trade. Coroplast is light, staked in seconds and printed the next business day after proof approval. Aluminum takes 3 business days and screws to a post, then stays. Our coroplast vs aluminum guide compares the two side by side.

How Long Does an Aluminum Sign Last?

Our .040 aluminum sign is guaranteed for 5+ years of outdoor durability, and it will not rust. That is the longest life we state on any rigid sign material, which is why aluminum is the standard for parking, address, gate, regulatory and job site signs that stay up.

The panel rarely fails first. A plain steel screw rusts and streaks the face, a wood post splits, a fence leans, or a mower clips the bottom edge. Use stainless or coated hardware, washers behind the screws, and a firmly set post, and the panel will outlast most of what holds it.

Rounded corners, offered at four radiuses, also help a sign near a walkway: a soft corner is less likely to catch clothing or bend when bumped. And a sign that faces a parking lot benefits from a post set back from bumpers, so a slow nudge from a car never reaches the panel.

How Does ACM Compare for Outdoor Panels?

ACM is weatherproof and made for permanent outdoor and indoor signs, so it belongs in the same long term group as aluminum. It is a 3 mm panel of two aluminum skins bonded to a solid core, printed directly on one side or both.

The difference is shape. ACM stays flatter across a wide panel, so it suits a 24 x 36 inch storefront or building sign. Solid aluminum suits the smaller sign on a post. We put a year count on the aluminum sign; for ACM we state weatherproof and permanent, without a year figure. Our ACM vs aluminum comparison covers the details.

How Long Does a Vinyl Banner Last Outside?

A vinyl banner lasts for an event, a promotion or a season, and longer when it is hung well. Our 13 oz standard vinyl is weather resistant and UV safe for outdoor use, and our 15 oz premium vinyl is made for long term outdoor displays. The banner page opens on a common size: A 6' × 3' 13oz Standard Custom Printed Banner is $133. Artwork prep is $14.99 per item. Printed in the USA in 3 business days and shipped nationwide, flat $10 shipping to any US address.

Wind is what ends most banners early. A loose banner flaps, and flapping works the grommets until they tear. Tie off every grommet, keep the banner taut, and on a chain link fence or an open lot choose mesh, which lets roughly 30 percent of the wind pass through.

What Shortens the Life of an Outdoor Sign?

Five things shorten outdoor sign life, and most of them have nothing to do with the panel:

  1. Hardware. Steel screws rust, zip ties go brittle in sun, and loose bolts let a sign rattle.
  2. Wind. A sign or banner that moves will wear at its holes, grommets and stake.
  3. Water at the bottom edge. Sprinklers and puddles hit the lowest inches every day.
  4. Impact. Mowers, car doors, carts and ladders bend corners and scratch faces.
  5. The wrong material. Foam board outside, or coroplast expected to last years.

How Do You Make an Outdoor Sign Last Longer?

Match the material to the time it must stand, then mount it so it cannot move. A few habits add real life to any outdoor sign:

  • Use stainless or coated screws and washers on metal signs.
  • Choose rounded corners on signs near walkways.
  • Set posts and stakes firmly, and keep signs out of sprinkler spray.
  • Pull temporary signs when the job ends instead of leaving them to weather.
  • Check permanent signs once or twice a year and tighten anything loose.
