Edge, Drip

Definition

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

Purpose

Drip edges are designed to direct water away from the structure, preventing water damage to the building's exterior and interior. They protect the building by ensuring that water drips off rather than seeping into the walls or windows.

Examples of Use

• Installing a drip edge at the eaves of a roof to prevent water from running down the exterior walls.
• Placing a drip edge over windows to keep water from seeping into the window frame and causing leaks.
• Using a drip edge on a window header to divert water away from the wall below.

Related Terms

• Eaves: The horizontal edge at the low side of a sloping roof.
• Flashing: Thin material used to prevent water penetration at joints and openings in a building.
• Gutter: A channel at the eaves for carrying off rainwater.
• Soffit: The underside of the eaves.

Notes

• Drip edges are typically made from metal or plastic and can be integrated into the roofing or window installation process.
• Proper installation of drip edges is essential for effective water management and long-term building protection.
