Drip Edge

Definition

A discontinuity or strip installed at roof eaves or over a window or wall component. It forces adhering drops of water to fall free of the face of the building rather than move farther toward the interior.

Purpose

Drip edges protect buildings from water damage by directing rainwater away from the roof, windows, and walls. They prevent water from seeping into the structure, reducing the risk of rot, mold, and structural damage.

Examples of Use

1. Roof Eaves: Installed along the edges of roofs to guide water into the gutters.
2. Windows and Doors: Used above windows and doors to prevent water from running down the building facade and entering through seams.
3. Wall Components: Applied to protruding wall features to ensure water drips away from the building.

Related Terms

• Fascia: A board that runs along the edge of the roof, typically where the gutter is attached.
• Soffit: The underside of the eaves, often ventilated to allow airflow into the attic.
• Flashing: Thin material used to prevent water penetration at joints and seams in buildings.

Notes

• Drip edges are typically made of metal, such as aluminum or galvanized steel, for durability.
• Proper installation is crucial to ensure effective water management and protection.
