What is roof remediation?
Roof remediation runs from finding and fixing a specific leak through to replacing a roof that's reached the end of its life. A roof is more than its sheets or membrane — it's the flashings, box gutters, parapets and penetrations where water actually gets in. Most roof leaks aren't a 'roof' problem; they're a detailing problem at one of those junctions.
Proper remediation traces the real ingress point before anyone quotes a re-roof, fixes the detailing or renews the system as needed, and — because a roof sits over occupied space — sequences the work with night and staged access so the building below keeps running.
6 signs your roof needs attention.
A roof usually leaks at a junction long before the whole thing fails. These are the signs it needs to be traced and fixed.
A roof leak finds everything below it.
Water from the roof doesn't stop at the ceiling. Left unactioned, it tracks through the building — and a detailing fix becomes a much bigger repair.
Damage to the units below
A roof leak runs into the top-floor interiors, then down through the building — ceilings, walls and finishes — long before the roof itself is the obvious cause.
Escalating repair scope
A failed flashing or box gutter caught early is a targeted repair. Ignored, it becomes water-damaged structure, internal make-good and a full re-roof.
Business & resident disruption
An unresolved roof leak over occupied apartments or a working tenancy is a recurring disruption — and a liability the owners corporation owns.
Find the leak before you replace the roof.
We don't quote a re-roof off a stain on a ceiling. We trace the actual ingress point, fix what's failed, and work over occupied space without shutting it down.
Trace the actual ingress point
A roof investigation finds where water is really getting in — flashing, box gutter, penetration or membrane — before anyone quotes a re-roof, so you only replace what's failed.
Fix the detailing or renew the system
We re-detail flashings, parapets and penetrations, upgrade box gutters and drainage, or renew the roofing system — matched to what the investigation found.
Sequence over occupied space
Roofs sit over people. We use night works and staged access to keep the building or tenancy running while the work happens above it.
Detail the junctions and close out
Roofs connect with facades and waterproofing. We detail the junctions so the whole top of the building sheds water, and close out the way defect rectification should.
The types of roof work we do.
Leak rectification through to full replacement — each scoped on its own or as part of a wider building program over occupied space.
Why our roof repairs hold.
The cheap quote re-roofs the lot or patches blind. Here's what tracing the leak first means for your building.
The proof is in the projects.
Mixed-use strata — St Leonards
Non-compliant waterproofing to the rooftop and balconies replaced with a sheet membrane system, with all windows and doors renewed. Three scopes integrated into a single 8-month program to minimise disruption and duplication.
"They combined three major scopes into one program. We expected 12 months of chaos — it was done in eight."
— STRATA MANAGER, ST LEONARDS
Mid-Rise Strata — Warwick Farm
One residential tower with active roof leaks. Rooftop waterproofing had failed and water was getting into the units below every time it rained. We stripped the roof back to substrate, found the root-cause of failure at service penetrations and installed a new sheet membrane system with proper falls and drainage.
"They set up their team and completed the works all at once, not a single day of lost time was caused."
— STRATA MANAGER, WARWICK FARM
Low-rise strata — Manly
Tight walk-up strata with one driveway and carpark. Full balcony re-waterproofing delivered balcony-by-balcony while the property kept garage and driveway access. Staged for minimal disruption across the works.
"They worked around our access the whole time — every owner kept use of their carpark, and only a couple of balconies were ever offline."
— STRATA MANAGER, MANLY
Traced, fixed and warranted. Verify everything.
Most roof leaks come back because the last contractor patched blind or over-quoted a re-roof. We trace it first and stand behind the fix.
From first call to fixed quote — leak traced first.

On your scheduleWe're a fit for some buildings, not all.
We'd rather tell you upfront than waste your committee's time.
This is for you if…
- You manage or own a strata or commercial building with roof leaks or an ageing roof.
- You want the actual ingress point found before committing to a re-roof.
- The building or tenancy is occupied and works need night or staged access.
- You need DBP-compliant documentation and a warranty your committee can rely on.
- Your project is from around $30K and up.
Probably not us if…
- You want a quick blind patch with no investigation of where the water's actually entering.
- You're after the cheapest re-roof without confirming what's actually failed.
- It's a small domestic roof repair under a few thousand dollars — a local roofer is a better fit.
- You need it done this week with no assessment — we trace the leak before we price.
You'll deal with the builder, not a call centre.
The easy money in roofing is quoting a full re-roof off a stain on a ceiling. I'd rather find out where the water's actually getting in — because nine times out of ten it's a flashing or a box gutter, not the whole roof. Send me what's happening and I'll tell you straight what it really needs.
What roof works cost in Sydney.
These are realistic ranges — your fixed price is confirmed after a building investigation, before any work starts.
Leak rectification — flashings, box gutters, penetrations and detailing.
Renewing roof sections, membranes or drainage across a building.
Full roof replacement programmes on larger strata and commercial buildings.
Cost depends on what's actually failed and access — which is exactly why we trace the leak before we quote, so you don't fund a re-roof you don't need.

We'll visit your building, confirm the source of the leak, and give you a clear, fixed-price path forward — free, no obligation. We respond within 24 hours.
