Drone, on-foot & water testing
Roof inspections Sydney
Every roof plane photographed from the air, every defect confirmed on foot, and a leak reproduced by water testing and traced to its cause — by licensed roofers, for commercial property, schools, churches and portfolios across Sydney and NSW.
Why two ways of looking
The drone finds it. The roofer decides what it is.
Most roof inspections are a man on a ladder looking at the bit of roof he can reach, and a report that says the rest “appeared satisfactory.” On a school with forty roof planes or a church nobody has stood on in thirty years, that is not an inspection — it is a guess with a photo attached.
We fly the whole roof first, so nothing is unseen. Then we walk what the drone has flagged, because a camera cannot tell fatigue from oxidation or a sealed flashing from a band-aid over an old leak. The method is the pairing. Either half alone is what everyone else sells.
In the air
Every plane, ridge, gutter, penetration and panel photographed from above — on a building with forty of each. Nothing unseen, nothing that needed a ladder.
On foot
A roofer walks what the drone flagged. Cracked or stained, fatigued or oxidised, sealed or band-aided — the camera raises it, the trade decides it.
What the drone sees
Every plane, every element
A ladder gives you the eaves. The drone photographs every roof plane, ridge, valley, box gutter, penetration and piece of plant, on a building that may have forty of each.
Where nobody can stand
Steep slate, fragile sheeting, glazed atria, roofs over live plant. Inspected without a foot on them and without a scaffold to inspect them from.
The same frame next year
With the whole roof on file, the second inspection is compared against the first, not remembered against it. Rust that has spread and a valley that has moved are visible as change, not opinion.
What only a roofer on foot can add
What the eye needs to touch
Whether a slate is cracked or just stained, whether lead has fatigued or just oxidised, whether a flashing is sealed or a band-aid over an old leak. The drone raises the question. On foot answers it.
Inside the box gutter
Sump depth, outlet size, the lining under the debris. The failure the standard COLORBOND® warranty excludes lives where the drone cannot look.
The trade call
Remaining life, what fails next, and a costed way to fix it — from the roofers who quote and complete this work every week, not from a checklist.
When it keeps leaking and nobody can say why
We find leaks by making them happen.
A leak that only shows in heavy rain cannot be found on a dry day by looking. So we reproduce it: controlled water testing, one isolated area at a time, with someone inside watching for it. The result is a cause per leak, not a theory per roof.
Every cause is graded. Confirmed means we reproduced it by testing or saw it directly. Probable means the physical evidence fits but testing did not reproduce it on the day. Possible means we are telling you we do not know yet. A leak investigation is a targeted report on the areas reported — not a whole-of-roof assessment, and it says so on the front.
Look first
A visual inspection of every element above and beside the reported ingress — sheeting, flashings, penetrations, gutters, parapets, cappings, plant — to find the likely entry points and decide the order of testing.
Then water, in stages
Water applied to one isolated area at a time, starting at the lowest point of the suspected path and working upslope, with time for it to travel and present inside before the next area starts. Re-tested where a result needs confirming.
Someone inside
A person stationed at the reported leak throughout, in direct contact with the roof. When water shows, the location, rate and timing are recorded and the outside test area is confirmed before anything moves on.
Three inspections, three different answers
Roof plumbing, not roof sheeting
A commercial metal roof, an active leak, and an owner ready to re-sheet. Traced element by element to clogged downpipes damming the valley — the roof itself was sound. That distinction is the difference between a clean-out and a re-roof.
The roof was not the problem
A school with ingress at the windows on three faces and a re-roof being discussed. Staged water testing reproduced the leaks at the window seals, found the gutters laid at no fall and a parapet cap ponding water, and graded each cause Confirmed or Probable. The report told them to engage the right trade for the seals — and priced only the roofing that was actually wrong.
Mixed repairs, no record
A heritage slate roof with slates of several ages and profiles from decades of patching, lead valleys heavily oxidised and fatigued, slates slipping into them. Individually each is a repair. Together they are a re-roof program, and the report says so.

Who this is for
Facilities managers, schools and universities, church property committees, strata and commercial owners — anyone responsible for a roof they cannot see and a budget they have to defend. An inspection is usually the first step to a planned program, or the second step after a leak.
Single homes are better served by our residential team. Findings come back as a written report with every element located, photographed, graded and costed, from a contractor who can also do the work — so you are never starting a procurement process from a document.
