Flashing & Trim

City Sheet Metal offers a complete suite of flashing and trim solutions designed to protect and finish vulnerable areas of the building envelope. From windows and doors to rooflines, corners, rake ends, and horizontal-to-vertical transitions, our products are engineered to manage water, prevent moisture intrusion, and deliver a clean, consistent exterior finish.

Manufactured in aluminum and pre-painted steel, CSM flashing and trim profiles feature crisp bends and colour-matched finishes for seamless integration with your project. Built to direct water away from joints and openings, these systems help reduce the risk of rot, leaks, and premature material failure—while maintaining sharp lines and long-term durability.

In addition to standard profiles, City Sheet Metal offers access to custom flashing solutions, including roof edge and gutter apron, allowing projects to accommodate unique details, non-standard conditions, and specific design requirements. With a broad range of profiles, materials, and finishes available, CSM provides flexible, reliable flashing and trim options that deliver both protection and polished detail where it matters most.
