Roof Leak Detection in Sydney
We find the source of stubborn leaks others miss — then fix it for good.
Water rarely enters where it appears. It runs along battens, follows rafters and shows up metres from the actual fault — which is why leaks so often get "fixed" two or three times before anyone finds the real cause.
We work methodically from the ceiling stain back to the entry point, checking valleys, flashings, ridge capping, penetrations and rusted sheets. You get a written report with photos of exactly where the water is getting in and what it will take to stop it.
What's included
- Full roof and roof-cavity inspection
- Hose testing to confirm the source
- Written report with photographs
- Permanent repair, not a patch
Signs you need this
- A leak that came back after being "fixed"
- Stains that appear only in certain wind directions
- Drips that start hours after rain stops
- Mould in a wardrobe or on a cornice
