Soffits are the underside areas of architectural structures such as eaves, cornices, or arches. In the context of buildings, particularly residential homes, soffits are the material that covers the underside of the roof overhang, extending from the edge of the eaves to the exterior wall of the house.
Soffits serve functional and aesthetic purposes. Functionally, they help to provide ventilation to the attic space, allowing air to flow freely and preventing moisture buildup, which can lead to issues like mould and rot. Additionally, soffits help to seal the underside of the roof and protect it from weather elements, pests, and debris.
Aesthetically, soffits provide a finished look to the eaves. They can be made from various materials such as wood, aluminum, vinyl, or fibre cement, and come in different styles and colours to complement the architectural style of the home. Some soffits also incorporate features like vents or lighting fixtures for added functionality and design appeal.
