Both the fascia and soffit are part of the exterior of the home and should be painted every 5-7 years, just like the exterior of a home. It is very common for the fascia to rot in older homes if it isnât painted often enough.The paint protects the fascia and soffit from the natural elements of weather.ain gutters are attached to the fascia, but an easier way to describe where the fascia is located is to say that it is what the Christmas lights are attached to.
