What is an Apron Flashing?
An apron flashing is a folded metal flashing used to create a watertight seal where the roof meets a wall or parapet. It directs rainwater away from the junction, preventing leaks and corrosion. Our COLORBOND® apron flashings are engineered for durability and designed to match your roof profile and wall finish perfectly.
When to Use an Apron Flashing
- At roof-to-wall junctions behind chimneys, parapets, or extensions
- For roof abutments and sidewall terminations
- As an alternative to cover flashings on low-slope roofs
- In combination with barge and ridge cappings for full edge protection
Choosing the Right Size & Profile
Apron flashings can be made in custom folds and dimensions to match your roofing type:
- Corrugated roof apron flashing – suits traditional profiles, most common in residential builds
- Trimdek / Monoclad apron flashing – for modern industrial or commercial designs
- ZINCALUME® apron flashing – best for coastal or high-moisture areas
- COLORBOND® roof-to-wall flashing – ideal for seamless integration with wall cladding
How to Measure an Apron Flashing
- Measure the vertical upstand required against the wall.
- Measure the horizontal leg that sits on the roof sheet (corrugation overlap).
- Add any extra returns or safety edges if your installer recommends them.
- Confirm total length and fold direction (left / right / straight).
Always double-check measurements before ordering, as each flashing is custom cut to size and folded for your roof profile.
