What Is Barge Capping?
Barge capping is a type of roof flashing designed to seal and protect the edges of your roof where the sheeting meets the barge board or gable end. It gives a clean, finished appearance while preventing rainwater and wind from entering the roof cavity. Whether you’re working with corrugated, Trimdek, or Klip-Lok® profiles, barge capping provides the perfect finishing touch to your COLORBOND® roof.
Installed along the edge of the roof, barge cappings act as a barrier against water ingress, corrosion, and debris build-up. They also help direct rainwater away from exposed roof edges, extending the life of your roof and improving overall weather performance.
Why Choose COLORBOND® Barge Cappings?
All our barge cappings are manufactured using genuine BlueScope .55 BMT steel — the same trusted material used across Australia’s best roofing systems.

Each flashing is cut to your required length (up to 8 metres) to ensure a professional, seamless fit on site.
