Many people do not know what a soffit or a fascia is despite their importance in building a house. This article provides an overview of their definitions, their basics, and their importance.

The fascia board is the part that connects the roof and the outer wall of the house. The correct name for the fascia is the roofline. Fascia refers to the mainboard carrying the gutter.


The fascia is the board on the roof’s lower end. The fascia is directly put on the lower edge of the roof trusses. The fascia board’s primary function is to support the bottom edge of the bottom row of tiles and carry the guttering. The fascia is strong enough to accommodate all the gallons of water going to the gutters per second during a heavy downpour.

The fascia protects the soffit. During the rainy season, soffits are prone to damage if the rainwater is not prevented from reaching them. The work of fascia is to stop the water from going to the soffit by directing it to the gutter.

You should perform maintenance on the fascia more often because of what can go wrong if it is not cared for adequately. Damaged fascia may lead to heat escaping from the house, potentially causing a rise in electric bills and increased heater usage.


This board is under the fascia board. A soffit is the visible part of the house from a distance. It is usually ventilated to allow the entrance of air to the rooftop. Others prefer when ventilations are on the top of the fascia board. The ventilation prevents air from condensing, thus cause timber decay.

Ventilations are very important for the house. The roof may overheat if there is no proper ventilation. The result is a quick breaking of shingles and ice dam formation during winter, which will eventually cause water to leak into the house.

A soffit is also crucial in creating an aesthetic for the house. Soffit makes the house look like it’s finished from the exterior view; it covers the rafters making up the roof overhang’s underside.

Fascia boards and soffit play an essential role in shaping and protecting the house. Knowing their purpose is vital in ensuring that they are protected from any damages.
