Roof Leak Detection

Roof Leak Detection Sydney – Find It Before It Finds You
Water’s sneaky. When your roof leaks, it rarely shows up right above the spot that’s wet. Water runs. It hides. It travels sideways through insulation, down walls, under floors. By the time you notice the stain on your ceiling, the damage could already be weeks old and metres wide.
That’s why accurate roof leak detection is everything.
At KLD Roof Repairs, we don’t guess. We track, test and pinpoint the problem using a mix of real-world experience and professional tools. We’ve been called in after others gave up. We’ve found leaks in places most people didn’t think to check.
If you’re searching for roof leak detection Sydney, you’re in the right place. And the right time to act is now.
Why Roof Leak Detection Matters
A leak isn’t just an inconvenience. It’s a threat that gets more expensive the longer it goes ignored. Slow, hidden leaks often cause more damage than sudden ones because you don’t see the danger until it’s too late.
Here’s what can happen when a leak goes undetected:
- Rotting timber supports and battens
- Soaked insulation that loses its function and holds moisture
- Black mould that creeps through plaster and into your air
- Electrical shorts and light fixture damage
- Stained ceilings, peeling paint and sagging gyprock
- Rising repair bills from structural and water damage
Early detection means early intervention. And that can save you thousands.


Signs You Might Have a Hidden Roof Leak
Not every leak starts with water pouring from the ceiling. In fact, most of the serious ones start small. Here’s what to watch for:
- Brown or yellow stains on your ceiling
- Musty smells in certain rooms
- Cracks or bubbling in paint
- Light rust around metal vents or skylights
- Mould growth near cornices or in corners
- Unexplained dampness or humidity indoors
- Dripping sounds with no visible water
If any of these are showing up, don’t wait. The sooner we find it, the less you’ll need to fix.
How Roof Leak Detection Works
So, how do we actually find a leak? It’s part skill, part science, and all about patience. Every leak is different, but our method stays consistent.

Visual Inspection
We start with the basics. We climb up and examine every part of the roof. We look for shifted tiles, rusted sheets, cracked mortar, loose flashing, clogged gutters and anything out of the ordinary. Experience helps here. Sometimes the problem is right there. Other times, it’s buried deep.

Water Testing
Still can’t see it? Time to simulate rain. We use controlled water testing to replicate the conditions that caused the leak. By soaking sections methodically and monitoring response inside the property, we can trace water flow with precision.

Moisture Meters
These handy devices help us detect moisture build-up behind walls or under insulation. They don’t just confirm that a leak exists, they help show exactly how far the water has travelled.

Thermal Imaging (if required)
For complex cases, we use thermal cameras to detect temperature differences caused by dampness behind surfaces. It’s fast, non-invasive and surprisingly accurate.

Internal Inspection
We check inside ceilings, wall cavities and roof voids where safe. A good look from underneath often reveals water trails, soaked timber, or long-term rot that helps confirm the leak path.
We put all this together to find out exactly where your roof is leaking, why it’s happening, and how to fix it right.
