Key Differences
Eaves refer to the part of the roof that projects beyond the walls of a building, creating an overhang. They offer protection from the elements by deflecting water away from the walls.
Soffits are the underside of the eaves. They can be ventilated to allow air flow into the attic, helping to prevent rot in the rafters and sheathing.
The eaves are visible from the building's exterior and can be a distinctive architectural feature, while the soffit is tucked away under the eaves and less prominent.
Soffits often house vents and can be made from various materials, such as wood, aluminum, or vinyl. Eaves without soffits can leave rafters exposed, which is sometimes a chosen aesthetic.
While eaves serve a protective and functional purpose in a building's design, soffits provide a finished look and contribute to the ventilation of the roof structure.
