Barge roll flashings are a combination of both the standard barge flashing and the barge roll which offers a neat rolled edge to the length of the roof sheet but also runs across the top of the roof line to give a more detailed finish to the roof shape.

Typically the barge roll flashing should be at least 40-50mm longer than the specified roof length to allow for the angle cutting at the top of the roof line and even longer if being used to continue past the gutter at the end of the roof sheets.
