Life Expectancy of Flags
The life expectancy of a flag is impossible to predict, as it is entirely dependent on the climatic conditions and hours of flying. We would advise that since most flags are either an act of courtesy (national flags) or advertising (company logos) it is best to have them in top condition by changing them regularly.
Wind and rain
In winds exceeding 25mph it is recommended that you lower your flag. Remember that if it is windy at ground level it is much worse at the top of the flagstaff. Heavy rain will increase the weight of the flag which will cause unnecessary wear, especially in high winds.
Damage to flags is often caused by objects that the flag beats against in the wind or by old style wooden flagstaffs which do not have a smooth finish. To reduce the risk of damage, ensure that the halyard is taut at all times, and that there is no risk of the flag snagging.
Washing and repair
Air pollution will cause white flags to become grey over time and dirt and acids carried in the atmosphere will destroy fibres in the flag material, therefore regular washing is recommended. Flags can be washed in a normal household washing machine set at a 40 degree wash with normal detergents.
Never store your flag when wet, always hang it up and allow it to dry fully before storage. When storing flags, keep them in a dry and ventilated place.
