Ceiling water stains are often misdiagnosed. The source may be a roof issue, blocked valley, cracked flashing, failed skylight membrane, or plumbing problem in the roof cavity. ALD uses infrared thermal imaging and visual assessment to locate the source of roof water ingress, so the right trade can carry out the right repair. This service is available for single-storey residential and commercial buildings. For multi-storey properties, contact us to discuss the best approach.
Thermal imaging and visual assessment for roof water ingress.
Roof leak detection is the process of identifying where water is entering a building from above — which is often not the same location as where the water is appearing inside. Water follows the path of least resistance through the roof structure, insulation, and ceiling cavity, which means the visible stain can be metres away from the actual breach.
Our process uses thermal imaging cameras to detect the temperature difference between wet and dry insulation and building materials — making the water's path visible. Combined with a systematic visual inspection of roofing materials, flashings, skylights, and penetrations, we can identify the precise entry point without removing any material.
Water stains or discolouration on ceilings or internal walls
Peeling paint on ceiling areas not associated with a bathroom or kitchen
Mould appearing in a room where moisture sources are limited
Dripping or pooling water during or after rain
A musty smell in roof cavities or upstairs rooms
Visible cracks or gaps around skylights, vents, or exhaust penetrations
Loose or displaced roofing material visible from ground level
We don't repair roofing — that's work for your roofer or builder. Our job is to give them the exact entry point so they're not pulling apart half a roof to find a cracked flashing.

For a standard single-storey roof leak detection inspection
No — we're leak detection specialists, not roofers or builders. Our job is to tell you exactly where the water is coming from so you can brief the right trade. You'll have a written report your roofer can act on immediately.
Yes. Chronic leaks often create more evidence, not less. Thermal imaging detects moisture saturation in insulation, ceiling sheets, and timber framing — even from long-term ingress. In some cases, older leaks reveal a larger affected area than the visible stain suggests, which our report will document.
Yes — both, as well as flat membrane roofs, Colorbond roofs, and mixed construction. The detection method varies slightly depending on the roofing type, but the outcome is the same: a written report with the identified entry point.
Our standard roof leak detection service is for single-storey residential and commercial buildings. If you have a multi-storey property, call us and we'll advise the appropriate approach — in some cases we can still assist using different access or thermal methods.
Thermal imaging is most effective within 24–72 hours of the last rain event, when moisture in the building materials is still present and temperature differentials are visible. If it's been dry for an extended period, we may recommend scheduling your inspection after the next rainfall for the most accurate results.
Waterproofing failures in balconies damage the units below and compromise structural integrity. We pinpoint the breach in membranes or joints, giving owners and building managers clear repair direction and cost estimates.

Infrared cameras reveal hidden moisture, heat loss, and structural issues invisible to the eye. We use this technology alongside acoustic and tracer gas methods to build a complete picture of what's happening in your property.

Water behind bathroom tiles is a structural threat. It rots timber, causes mould, and spreads silently. We find the leak — whether in plumbing, waterproofing, or grout — before the damage spreads. Early detection saves thousands in structural repairs.
