After a quake, roofs can shift in ways that are not obvious from inside. Here is what to check safely from the ground and when to call a professional in NZ.
New Zealand is seismically active, and even a moderate earthquake can shift tiles, crack mortar, loosen flashings or open small gaps in a roof. The damage is often invisible from inside until it rains. Here is how to check safely and what warrants a professional inspection.
Check Safely From the Ground
- Slipped, cracked or dislodged tiles visible from the ground
- Debris of tile or mortar in gutters or on the ground
- Visibly bent or lifted flashings and ridge capping
- New gaps around chimneys, vents or skylights
- Damp patches on ceilings after the next rain
Why Quake Damage Hides
Shaking can hairline-crack tiles, dislodge mortar bedding and loosen fixings without anything looking dramatic. These small failures let water in slowly, showing up as stains weeks later. Chimneys and heavy ridge details are especially prone to movement and worth close attention.
When to Call a Professional
Do not climb a potentially damaged roof yourself — that is when falls happen. If you see slipped tiles, damaged flashings or interior damp, get a professional inspection. We carry out safe post-event roof inspections across Auckland and give a clear written report on any damage found.
