Eaves and soffits are related but distinct components of a roof. Eaves refer to the edge of the roof that overhangs the walls of a building, providing protection from rain. Soffits are the underside part of the eaves, installed horizontally from the siding to the roof edge, often ventilated to help with airflow in the attic. Both play crucial roles in roof structure and ventilation.
