COLORBOND® Corner Flashing 90mm

What COLORBOND® Corner Flashing Is For

COLORBOND® corner flashing — also called corner capping — covers and weatherproofs the external corners where two roof or wall sheets meet. It's used on roof and wall corners, sheds and garages, and as barge capping along gable ends, sealing the one junction most likely to let water in, with COLORBOND® corner roof flashing and larger 140mm corner roof flashing offering options for different designs.

Corner Flashing or Corner Capping?

The two terms are used interchangeably. "Capping" usually refers to the external cover that sits over a corner or barge line — which is exactly what this profile does. If you've been quoted for either, this is the part you need, with a COLORBOND® MATT corner flashing option available for low-sheen, modern roofs.

Fitting Tips

• Lap at least one rib over corrugated sheeting for a watertight join.

• Fix at consistent spacing with the correct screws or rivets for your sheet.

• Seal laps with a neutral-cure roof sealant.

• Keep a consistent fall so water runs off, not back into the corner.
