The soffit is the underside of the overhanging roof that is exposed. While both of these materials are used when installing a roof, this one in particular is used on the eaves of the outside of the home, closing any space between the home and the eave. It extends from the structure’s side all the way to the edges of eaves. Soffit installation in Houston is done between fascia and the walls.

 

Hidden, it provides ventilation that fascia may not provide to the home itself. The material is usually made of either vinyl or aluminum, but wood can be used in some homes. The material is vulnerable to weather and the elements when it is constantly exposed, this means that if there is water flowing constantly over areas with soffit, they are likely to be damaged.
