How long will a flag last? There is no exact answer.
How to Care of Your Flag With such variation in degrees of usage, constantly changing weather patterns, and different climate conditions where displayed, it's not easily measured. Generally, a polyester flag is expected to last approximately 90 days, based on daily usage from sunrise to sunset. Tests have shown that in some cases a flag flown 24 hours a day will last only 1/4 as long as one flown during daylight hours only.
Unfortunately, flags don't last forever, after a while the cloth will sooner or later succumb to the elements it is exposed to. It has been documented that reasonably good care and love for the flag can greatly prolong the life of your flag.
Things that will help prolong the life of a flag:
- Try to avoid flying your flag in the rain or snow.
- High winds combined with water puts undue strain on the flag.
- You can prevent mildew by letting your flag dry thoroughly before storing it.
- The fly end will be the first to reveal wear and tear. When this begins, you may take the flag down trim off the old hem and re-hem your flag. Do this at the first sign of fraying to prevent the material from shredding. Doing so could give you one or possibly two more display times out of the flag.
- Beware of obstacles from other nearby surfaces. (Such trees or phone lines) This will cause a weakening of the materials.
- Use the proper size of flag on your flagpole. A flag that is too large may cause the pole and flag undue stress in high winds.
- Smog and atmosphere conditions will not only cause discoloration, but weaken the fabric of your flag.
- Continuous day and night display will shorten the life of your flag.
