Aluminum flashing is a corrosion-resistant metal material used in construction to direct water away from roofs, walls, and openings.

Aluminum flashing is a thin, formed metal material installed at joints, transitions, and penetrations in building assemblies to prevent water intrusion. It is commonly used around roofs, windows, doors, chimneys, and wall intersections to channel water away from vulnerable areas of the building envelope.

Due to its lightweight nature and corrosion resistance, aluminum flashing is widely used in both residential and commercial construction. It is easy to cut, bend, and shape on-site, making it suitable for custom detailing and complex flashing conditions. Aluminum flashing is often prefinished or coated to improve durability and appearance.

From a performance standpoint, aluminum flashing must be properly installed and compatible with surrounding materials to be effective. Contact with certain treated woods or dissimilar metals can cause corrosion if not properly isolated. When correctly detailed and maintained, aluminum flashing plays a critical role in protecting structures from moisture damage and extending the lifespan of building components.

Aluminum flashing is often preferred in coastal areas because it resists rust better than many other flashing materials when properly protected from salt exposure.
