The Overtile Flashing 1.8m x 175mm x 4 Combo is a practical roofing solution designed to help protect vulnerable roof junctions against water penetration. Supplied as a convenient 4-piece combo, with each flashing measuring 1.8 metres long and 175mm wide, it is suitable for compatible tiled roofing installations, repairs and renovation projects.
Overtile flashing is installed over compatible roof tiles at junctions where additional weather protection is required, helping direct rainwater away from areas that may otherwise be susceptible to leaks.
Overtile Flashing 1.8m x 175mm

- Product type: Overtile Flashing
- Length: 1.8m per piece
- Width: 175mm
- Quantity: 4 pieces
- Pack type: Combo
- Application: Roofing

The four-piece pack provides a practical quantity for roofing repairs, maintenance and selected new installations.
Helps Protect Against Water Penetration
Roof junctions are particularly vulnerable to rainwater if they are not correctly sealed and flashed.
Properly installed overtile flashing helps manage water movement by directing rainwater away from vulnerable joints and onto the roof covering.
Typical applications may include compatible:
- Tiled roofs
- Roof-to-wall junctions
- Roofing repairs
- Renovations
- Extensions
- Residential roofing
- Building maintenance projects
The exact application will depend on the roof design and flashing requirements.
Convenient 4-Piece Combo
The 4-piece combo provides a total nominal length of 7.2 metres before allowing for installation overlaps.
Each individual flashing measures:
- Length: 1.8m
- Width: 175mm
- Quantity: 4 pieces
Actual usable coverage will be less than the combined length where pieces need to overlap during installation.

Installation Guidelines
Correct installation is essential for effective weather protection.
The flashing should be positioned with sufficient overlap and integrated correctly with the existing roof covering. Fixings and sealing methods should be appropriate for the roof construction and flashing material.
Avoid unnecessary penetrations through areas where water may collect or flow.
For complex roof junctions or leak repairs, installation by an experienced roofing professional is recommended.
Measure Before Purchasing
Before purchasing, measure the complete area requiring flashing and allow for:
- Required overlaps
- Roof angles
- Junction lengths
- Cutting and trimming
- Corners and transitions
- Installation waste
The four pieces provide 7.2m of nominal combined length, but the final effective coverage depends on the installation method and required overlaps.
