What Is Roof Flashing?
Flashing is a material—typically metal—installed around roof edges, joints, and openings such as windows and doors to prevent water from seeping into the structure. Flashing directs water away from vulnerable areas and plays a critical role in ensuring that your building is fully protected from water damage.
Flashing is often paired with gutters and downspouts to create a comprehensive water management system. Available in materials such as aluminum, copper, and stainless steel, flashing can be tailored to fit your building’s architecture and provide long-lasting protection against moisture.

Benefits of Roof Flashing
- Waterproofing Protection: Flashing prevents water from infiltrating areas prone to leaks, such as roof valleys and joints.
- Durable and Weather-Resistant: Flashing materials like aluminum and copper are resistant to corrosion and extreme weather, ensuring long-term performance.
- Seamless Integration: Flashing integrates seamlessly with gutters and downspouts, providing a cohesive water management system.
- Low Maintenance: Flashing requires minimal upkeep while protecting the structure from costly water damage.
Material Options for Flashing
- Aluminum Flashing: Lightweight, corrosion-resistant, and versatile, aluminum flashing is ideal for most applications.
- Copper Flashing: Known for its durability and aesthetic appeal, copper flashing develops a natural patina over time.
- Stainless Steel Flashing: Strong and highly resistant to corrosion, stainless steel is ideal for industrial and commercial applications.

Applications of Flashing
- Roof Protection: Install flashing around roof edges, valleys, and chimneys to prevent leaks.
- Windows and Doors: Flashing around window and door openings helps prevent water from seeping into the structure.
- Foundation Protection: Flashing can be applied along the foundation to direct water away and prevent moisture buildup.
- Commercial and Industrial Buildings: Flashing is essential for protecting larger structures where water management is crucial.
