Copper Flashing

Definition

Copper flashing consists of sheets of copper that cover open joints on exterior construction to prevent water leakage.

Purpose

The purpose of copper flashing is to protect building structures from water infiltration by sealing joints and seams, ensuring long-term durability and preventing damage from moisture.

Examples of Use

• Roof valleys and edges use copper flashing to direct water away from the structure and prevent leaks.
• Chimney and wall junctions are sealed with copper flashing to protect against water penetration.
• Window and door openings use copper flashing to ensure a watertight seal and prevent moisture damage.

Related Terms

• Sealant: A substance used to block the passage of fluids through the surface or joints or openings in materials.
• Weatherproofing: Methods and materials used to protect a structure from the effects of weather.

Notes

Copper flashing is chosen for its durability, malleability, and resistance to corrosion. Proper installation is crucial to ensure effective protection against water infiltration.
