J-Trim Standing Seam Wall Flashing is a metal roofing accessory designed for detailing areas where standing seam roofing systems meet walls or other vertical building structures. These junctions require carefully formed flashing components to help protect the roofing assembly from rain, snow, and wind-driven moisture.
The profile features a 5″ lower flange, a 1¾″ vertical section, and a 3″ upper return flange. This J-shaped configuration creates a defined channel for integration with compatible standing seam roofing components and provides a neat, consistent finish at roof-to-wall transitions.
Designed specifically for standing seam metal roofing applications, helps cover exposed junctions and supports the overall weather protection of the roofing system. Its formed steel profile provides a practical solution for architectural roofing details where precise alignment and clean transitions are important.
When installed with appropriate fastening, sealing, and waterproofing details, the flashing helps reduce the risk of moisture penetration at vulnerable roof-to-wall connections.
Suitable for residential and light commercial roofing projects, J-Trim Standing Seam Wall Flashing can be used in both new construction and roof renovation applications.
