Soffit and fascia are elements of the roof. They have a protective and aesthetic role, but unfortunately, in many cases, they do not get the attention they deserve.
Fascia is the vertical barrier between the edge of the roof and the outside, an architectural feature with a role in protecting the interior of the roof from weather damage. Being fixed to the lower ends of the roof, it often has to support a row of tiles, as well as the weight of the gutters (and that of the water that goes through them!).
The aesthetic role of the fascia board comes from the fact that it covers the open ends of the rafters, completing the aspect of the roof.
On the other hand, soffit is the underside section beneath the roof extending over the walls. It hides the rafters (exposed rafters is not a pretty sight) and also have an important role in proper attic ventilation, preventing moisture build-up and its unwanted consequences. This is why soffits are often perforated or vented.
As in the case of fascia, aesthetics are secondary, but important in raising the overall curb appeal of the house. Soffits ensure a finished exterior aspect of houses.
