Eaves

Definition

The horizontal edge at the low side of a sloping roof.

Purpose

Eaves are designed to throw water clear of the walls and foundations of a building, protecting them from water damage. They also provide shading and can enhance the aesthetic appeal of a building.

Examples of Use

• Overhanging eaves help protect the exterior walls from rainwater runoff.
• Eaves can provide shade to windows, reducing cooling costs in the summer.
• In snowy climates, extended eaves can help prevent ice dams by allowing snow to fall away from the house.

Related Terms

• Soffit: The underside of the eaves.
• Fascia: The vertical finishing edge connected to the ends of the rafters or trusses.
• Gutter: A channel at the eaves for carrying off rainwater.
• Overhang: The portion of the roof that extends beyond the exterior wall.

Notes

• Proper ventilation of eaves is essential to prevent moisture buildup in the roof space.
• Eaves can be architecturally significant and influence the overall design and style of a building.
