The answer to how often you need to repaint your fascia boards largely depends on the material of which they are made and the climate in which you live. For example, if your fascia boards are made of wood and you live in an area with high humidity, you will likely need to repaint them more often than if they were made of vinyl or composite material. In general, though, most people should expect to repaint their fascia boards every 3-5 years.
