There is no exact answer. The U.S. Government generally expects a flag to last approximately 90 days based on daily usage from sunrise to sunset - but not during periods of inclement weather. Tests have shown that in some cases a flag flown 24 hours a day will last only one-fourth as long as one flown during daylight hours only. The major enemies of a flag are the wind and sun. Neither you nor we can control the weather, but you can take care of your flag and lengthen its life.

#1. Occasional washing in warm mild detergent water will prevent dirt and pollutants from attacking the fabric.
#2. Have your flag repaired at the first sign of fraying.

Our flags are manufactured to give maximum service in return for reasonable care. No two flags wear the same. Because weather conditions vary, most flags flown 24 hours a day 7 days a week will need to be replaced two or three times a year. The best way to stretch your "flag dollars" is to have three flags: one flying, one in the wash, and a clean one in reserve for special occasions.
