Precision Wall Flashing: The Essential Watertight Joint for Metal Roofing
Protect your roof-to-wall junction with custom-engineered metal flashing designed to prevent leaks, enhance durability, and deliver a clean architectural finish.
When a roof meets a wall, it becomes the most vulnerable point for water penetration. Our wall flashing systems are designed to create a secure, leak-proof transition, ensuring long-term structural protection for both residential and commercial buildings.
Custom Engineered for Every Joint
- Standard Girths: 300mm, 450mm, 600mm, 900mm
- Tailored Solutions: Custom girths from 150mm onwards based on project design
- Length Options: 900mm – 3050mm to minimize joints and leakage risks
Premium Materials for Maximum Longevity
PPGL & PPGI Steel
Pre-painted Galvalume and Galvanized steel provide strong corrosion resistance and long-term durability.
Advanced Coating Protection
Aluminum-Zinc coatings (AZ50–AZ150) and Zinc coatings (Z080–Z275) ensure protection in harsh tropical and coastal environments.
Certified Quality: Manufactured using premium materials from BlueScope and CSC.
Seamless Color Integration
- BlueScope Range: Prima Maju series and Clean Colorbond®
- CSC Range: Primero series for tropical durability
- Custom Colors: Wide range to match modern and traditional roof designs
Key Functions of Wall Flashing
Water Diversion
Directs rainwater away from roof joints to prevent leaks and water ingress.
Structural Protection
Prevents moisture from damaging trusses and wall structures.
Thermal Movement Control
Allows expansion and contraction without breaking the seal.
Aesthetic Finish
Covers exposed joints for a clean and professional roof appearance.
Professional Installation Tips
1. Precision Overlapping
Maintain minimum 150mm overlap (200mm for low pitch roofs) to prevent backflow leakage.
2. Over-and-Under Rule
Ensure flashing is tucked behind wall cladding or into a reglet groove for proper sealing.
3. Use Quality Sealants
Apply neutral cure silicone to avoid corrosion on coated steel surfaces.
4. Correct Fastening
- Use stitch screws with EPDM washers
- Avoid fastening in roof valleys
- Maintain 300mm – 450mm spacing
5. Clean as You Go
Remove metal filings immediately to prevent rust stains and coating damage.
6. Rib Notching
Use foam closures or notching to seal rib gaps against water and pests.
Protect Your Roof with Precision
