Maintenance of the flagpole and the flag

A flagpole needs little maintenance, but not none. The halyard, pulley and fittings wear with sun, wind and rain, and by the sea the salt air speeds up that wear. The flag wears even faster. For the national flag, Decreto-Lei n.º 150/87 provides for it to be displayed in good condition, so maintenance is part of flying the flag. This guide describes the usual care.

Regular checks

It is common to check the pole at least once a year and after storms. The usual points are:

On a pole with a tilting base, the top is checked with the pole lying down, without working at height.

The halyard

The halyard is the part that wears most. Ultraviolet radiation weakens the fibres, and the wind rubs the rope against the pulley and the pole. A faded halyard or one with broken fibres can snap in the wind. On a pole with an external halyard, replacing it is simple; on a pole with an internal halyard, the counterweight inside the tube makes the job longer. Replacement is described in the guide to flagpole repair.

Cleaning and sea air

Aluminium and fibreglass poles are cleaned with water and a mild detergent. On the coastal strip, in the Azores and in Madeira, salt settles on the pole and fittings and speeds up corrosion. It is common to rinse the pole with fresh water a few times a year and to check the joints between parts of different metals, such as steel bolts on an aluminium pole, where corrosion usually starts.

The flag in good condition

Decreto-Lei n.º 150/87 provides for the national flag to be displayed according to the official pattern and in good condition, so as to preserve the dignity due to it. According to the memorandum on flags of the Câmara Municipal do Sabugal, the flag is kept in impeccable condition and replaced when it is fraying, torn or faded.

The usual care of the flag is:

• Strong wind: a flag taken down during periods of strong wind wears less at the fly.
• Damp: a wet flag is dried before it is stored, to avoid mould.
• Washing: polyester flags are washed by hand or in the machine, at a low temperature.
• Repair: a small tear at the fly can be sewn, as long as the flag keeps the proportions of the official pattern.

The price of a new flag is covered in the guide to buying a flag.

The foundation

The concrete foundation rarely needs maintenance, but cracks, water collecting in the sleeve or corroded bolts on the tilting base are warning signs. A pole that is no longer vertical points to a problem with the foundation or the base. The risks are described in the guide to flagpole safety.

Maintenance and lifespan

Regular maintenance extends the life of the pole and prevents larger repairs. The lifespan of each material is described in the guide to flagpole lifespan, and the parts in the guide to flagpole accessories.
