There is no definite answer to the question of how long a flag should last. The life of a flag can vary depending on the weather, its location, airborne contamination, and how often it is flown.
Our flags are manufactured to give maximum service in return for reasonable care and prudent use. Remember, no two flags receive identical wear. Because weather conditions vary, wearing conditions vary, and consequently, the life of each flag is different.
Remember, your flag is a piece of cloth that works very, very hard. Throughout its lifetime, your flag shakes, trembles, drapes, snaps, chafes, bakes, freezes, ripples, flutters, furls, twists, flaps, strains, flies, unfurls, and hangs! Is it any wonder that a flag that flies continuously needs replacing two or three times a year?
Wind, water, sun, and carelessness are the major enemies of a flag. No one can control the weather, but you can take some important steps to lengthen the life of your flag. Occasionally washing your flag in warm detergent water will prevent pollutants and dirt from weakening the fabric. Always let your flag dry thoroughly before storing it to prevent mildew or color transfer. Always keep your flagpole as clean as possible and move your pole if your flag does not have adequate room to fly unobstructed.
