What are Fascias?
The fascia is mounted at the point where the roof meets the outer walls of the house and is often called the roofline. However most people refer to it by the name of the main board that carries the gutter which is the fascia or fascias. Not many people are familiar with the terms.
Fascia
The fascia board is the long, straight board that runs along the lower edge of the roof. The fascia is fixed directly to the roof trusses and usually does all the work of supporting the bottom row of tiles and carrying all the guttering.
Soffit
The soffit board is tucked away under the fascia board. It is usually the board that you see most of from street level. The soffit can be ventilated to allow the flow of air into the roof area. Alternatively, ventilation can be provided over the top of the fascia board. Many people prefer the latter solution these days. Without adequate ventilation, condensation will form in the roof void increasing the risk of timber decay.
