Johnson Roofing offers expert flashing repair in Auckland to protect your home from leaks and water damage. Trust our specialists for lasting solutions.
Auckland’s wet winters, salty coastal air, and strong winds put constant stress on your roof, with flashing being one of the most vulnerable points. When this thin barrier fails, water intrusion can cause leaks that quickly escalate into costly structural and interior damage. At Johnson Roofing, we specialise in expert flashing repair and other roofing services that not only stop leaks but also ensure long-term performance and warranty compliance.
Why Flashing Matters More Than You Think
Roof flashing is a vital component of any roofing system. It is typically made from durable materials such as aluminium, lead, or galvanised steel, and is installed to direct water away from vulnerable areas of the roof. When flashing is correctly installed and maintained, it helps prevent leaks and prolongs the lifespan of your roof.
Key purposes of roof flashing include:
• Sealing roof joints around chimneys, skylights, and vents.
• Protecting valleys where two roof planes meet.
• Preventing water intrusion at roof edges and walls.
• Directing rainwater away from structural elements to avoid damage.
When flashing is compromised, water can easily find its way inside your home, creating damage that often goes unnoticed until it becomes a major problem.
How We Diagnose Flashing Failures
Unlike quick patch jobs, our approach is rooted in careful investigation:
• Moisture mapping to trace water intrusion paths
• Visual and cavity inspections for corrosion, gaps, or poor sequencing
• Fastener and lap checks for movement or sealant failure
• Compatibility tests to rule out galvanic corrosion between metals
By understanding why the flashing failed, we design a solution that lasts, not just a temporary stopgap.
Risks of Ignoring Damaged Flashing
Delaying repairs to damaged flashing can lead to extensive problems that compromise both your home’s structure and safety. Even minor leaks can escalate quickly, resulting in issues that are costly and time-consuming to repair.
Potential risks of ignoring flashing damage include:
• Structural water damage to walls and ceilings.
• Growth of mould and mildew, impacting health.
• Reduced home value due to roofing issues.
• Costly repairs compared to early intervention.
By addressing flashing issues promptly, you can protect your home, maintain its value, and avoid unnecessary stress and expense.
