If you own a business, you know how important advertising can be. A great way to get your reputation noticed by customers in your local area is by purchasing an exterior sign to market your services. There are many options to choose from, but to get the most out of your investment you will probably want to know how long outdoor signs last. This actually depends on a number of factors, so knowing how to choose the right sign for your needs is very important.

Outdoor SignageUltimately, having a sign isn’t going to be a cost-effective marketing solution if it fails to last a reasonable amount of time. Here are some of the key factors that affect the life of an outdoor sign. Be sure to do your research well beforehand when choosing a sign company. The latter will be able to recommend specific materials and styles for your advertising needs.


Determining the life of an exterior sign

  • What is the climate like where you live?
  • Proper vinyl is essential
  • At what angle will the sign be installed?
  • Do you live in area prone to pollution?
  • What colours of ink do you want the sign to have?

If you live in a climate that is prone to greater sunlight intensity, you can expect your exterior sign to not last as long as it would somewhere else. The more UV rays that come into contact with your sign, the faster it will fade and deteriorate over time. This is a very point to take into consideration today especially, given the presence of global warming. Whether you tend to agree with this theory or not, it has been scientifically proven that the Earth’s ozone layer is depleting quicker than it has in past years. This correlates directly with vinyl sign longevity, as the latter is affected most by UV ray contact.

Not all vinyl is the same. Some are of better quality than others; one aspect of better builds is that they last longer than their cheaper counterparts under similar conditions. The four most commonly used types of vinyl are Calendared PVC, Cast PVC, Metalized Polyester, and Fluorescents. Calendared PVC tends to last about 3-6 years in external environments on average; the range is characteristic of the colour of ink being used.

Cast PVC can be considered a step from the Calendared vinyl, and its projected life span is about 25% longer, or a couple more years (although some can last up to 12 years). Metalized Polyester produces a shiny, metallic look. While they may be attractive, the effect of this glamour is a much shorter life span. You can expect one of these signs to last between 6 months and 2 years. Fluorescent signs last about 2-5 years depending on the hue that is being used.

Other factors that will come into play are the angle at which the sign is being installed (the closer you get to horizontal, the more contact the sign will have with the sun’s UV rays). Pollutants in the atmosphere as well as the colour of ink being used on the sign will also affect its lifespan. Thus, there are many factors to consider when buying an outdoor sign. You will need to decide what your needs are in relation to how long you want the sign to last.
