A flag's lifespan is often in the hands of its owner. National Flag and Branding estimates that a polyester flag will last about 90 days if it is only flown from sunrise to sunset in good weather. Flags flown 24 hours a day will typically last one half to one third as long. Larger flags have a shorter life than smaller ones because they are exposed to higher wind speeds and the fly ends have a stronger whiplash effect.
Extreme Weather Conditions
Strong winds and rain can cause damage to flags of many fabrics. Even all-weather flags will wear faster in these conditions. It's best to take flags down in bad weather. It's also important to check your flag regularly for damage. Larger flags (1800 x 1200mm and up) need to be checked for wear at least twice a month. Many people will buy two or three flags per pole and rotate them frequently. That way one flag can be repaired and cleaned while the other is displayed.
Caring for your Flag
• Do not store a damp flag. It can get mouldy. Allow it to dry and store it in a moisture-proof container.
• You can do minor repairs to your flag as long as they are not noticeable and it is still a fitting emblem. Flags in bad condition should be retired and replaced.
• Position your flagpole in a clear area where your flag won't whip against rough surfaces, branches or anything it can snag on.
• Keep your flagpole clean and in good repair. Rust can stain and corrode your flag and rough edges can tear it.
Choosing a Flagpole
Flags and flagpoles come in a variety of sizes. Poles specified for indoor flags, should only be used inside, and outdoor poles should only be used outside. The larger the flag, the taller a flagpole must be to accommodate it. Generally the length of the flag should be one third to one quarter the height of the flagpole.
