Most roof leaks are harder to find than they look. Where water shows up on your ceiling is rarely where it's getting in -- which is why so many roof repairs fail the first time. We investigate the whole roof, find the actual source, and fix it properly. First time.
You'll Finally Know Where It's Actually Coming From
A stain on the ceiling tells you water is getting in. It doesn't tell you where. Water travels along rafters and roof sheeting before it finds a low point and drips -- which means the entry point could be metres away from where the damage appears. We use thermal imaging cameras and a structured investigation process to find the real source before we touch anything. No guessing. No patching the wrong spot and hoping for the best.
Fixed So It Holds -- Not Just Until the Next Heavy Rain
An intermittent leak that only appears in a downpour is still doing damage every time it rains -- to your insulation, your plasterboard, your ceiling, and potentially your timber framing. We fix the cause, not just the visible symptom. And on complex jobs where multiple issues exist, we map them all and tell you what to expect before we leave -- so there are no surprises after the next rain.
A Plumber Is Exactly Who You Need -- Here's Why
Most people with a roof leak call a roofer first. Understandably. But metal roof leak investigation and repair -- Colorbond, corrugated iron, flat roofs, flashings -- falls under a plumbing licence, not a roofing licence. And most roofers specialise in installing new roofs, not tracking down leaks on existing ones. Sean's team are licensed, equipped, and experienced specifically in finding and fixing the leaks that others miss -- or never looked for properly in the first place.
Clear Options. Honest Advice. No Pressure.
Once we know exactly what's causing the leak, we give you a clear picture of what fixing it properly involves and what it will cost. Sometimes it's a targeted repair. Sometimes the roof needs more -- and we'll tell you that honestly rather than patch it and send you an invoice. You get the information you need to make the right call for your home and your budget.

Why the Damage You Can See Is Rarely the Whole Story
A stain on the ceiling. Plaster that's starting to bubble. Water appearing inside the house during a storm. You know something's wrong -- but you're not sure how bad it is, whether it's going to get worse, or even who the right person to call is. A roofer? A plumber? Someone else entirely?
The short answer is a licensed plumber -- specifically one who specialises in roof leak investigation. And the reason most roof repairs fail comes down to something most homeowners have never been told.
Where Water Shows Up Is Almost Never Where It's Getting In
Where Water Shows Up Is Almost Never Where It's Getting In
Water doesn't fall straight down through a roof. It enters at one point, then travels -- along a rafter, across a sheet of roof iron, down a timber purlin -- until it finds a low point and drips. That low point can be half a metre from the entry point. It can be three metres away. It can be on the opposite side of a roof ridge entirely.
A plumber who patches the area above the stain and leaves has almost certainly not fixed the leak. They've patched the wrong spot entirely.
Finding the actual entry point requires a structured investigation of the whole roof -- not just the section above the ceiling stain.
For instance, not long ago Sean visited a recently purchased home where the roof only leaked in heavy downpours. Every previous attempt to fix it had failed because the patch was applied above the stain. When Sean investigated the whole roof -- removing the ridge capping to inspect the sheet ends -- he found the real cause: not one of the roof sheets on a 1960s extension had been weather-folded. In normal rain there wasn't enough force to drive water over the sheet ends. In a heavy downpour there was -- and the leak had been occurring every time it bucketed down for years.
One proper investigation. One permanent fix.
The Damage Is Compounding While the Leak Goes Unfixed
The Damage Is Compounding While the Leak Goes Unfixed
Every time it rains and the leak isn't properly repaired, the damage inside your ceiling cavity gets worse. Insulation gets wetter and loses its effectiveness. Plasterboard softens incrementally -- the stain you can see is just the surface sign of what's happening above it. And in the right conditions, mould establishes itself in the ceiling cavity long before it's visible from below.
A leak that only happens twice a year is still wetting your ceiling cavity twice a year -- and the cumulative damage compounds faster than most people expect. The longer it goes unfixed, the more expensive the eventual repair becomes.
How Integrity Plumbing Approaches a Stormwater Problem -- And Why It Matters
We Look at the Whole System -- Not Just the Section That's Causing Visible Problems
The most common mistake in stormwater work is treating it as a single-point problem. The gutter overflows at the back of the house, so the plumber checks the downpipe, clears a partial blockage, and leaves.
What they didn't check was why that section got blocked in the first place -- and whether the pipe further downstream is clear, collapsed, or full of roots.
A few years ago, Sean was called to a property where one side of the house was draining and the other wasn't. Large pine trees had been planted directly over several sections of the stormwater line. The diagnosis was complicated by something the previous plumber had missed entirely -- the property had two separate stormwater connections that weren't visible from the surface.
"We spent extra time working out what was actually happening -- why was one side of the house working and the other wasn't? You don't want to just fix one section and leave the rest." -- Sean Lawler
Once the full system was mapped and both connections found, the diagnosis was clear -- pine roots had blocked one branch completely. A high-pressure jet cleared the lines and restored full drainage.
But here's the part that saves the client real money: because pine roots over a stormwater line will always come back, Integrity now revisits the property once a year for a maintenance flush. One routine visit costs a fraction of what an emergency excavation would cost if the roots were left to fully block the line. The client knows exactly what they're dealing with, knows it's being managed, and never has to deal with an emergency.
That's what you get when your plumber understands the whole picture -- not just the section that was obviously blocked.
You See Exactly What We Find
Surface symptoms tell you something is wrong. They don't tell you what, where, or how bad.
A camera run through the full stormwater line -- from the downpipes all the way to where your drainage connects to the street -- shows you the condition of the pipe, the location of any problems, and the extent of the damage. We show you the footage. You see what we see. There's no guesswork, no diagnosis based on surface symptoms alone, and no chance of paying to fix the wrong thing.
Some Causes Aren't What You'd Expect
Sean was called to a home where the toilet was blocking up roughly once a week. Every time, the plumber cleared it and left. Every time, it came back. For months.
Sean put a camera down the line. At the bottom, lodged in the pipe, was a plastic plate. A child had flushed it down the toilet. It sat in the line and caught toilet paper intermittently -- enough to cause a blockage, not enough to stop all flow. Every plumber who cleared it moved the paper. None of them found the plate.
One camera investigation. One permanent fix.
That's what it means to diagnose properly.
We Fix the Cause So The Problem Doesn’t Come Back
Some stormwater problems are one-off events -- a blockage caused by specific debris, cleared once and unlikely to return. Others are ongoing -- trees over pipes, old clay drainage with failing joints, ground movement that has cracked a section of line.
For ongoing problems, we don't just clear and leave. We explain the nature of the issue honestly and give you options. Sometimes that means a repair. Sometimes it means a maintenance schedule that keeps the problem managed before it becomes an emergency. Either way, you’ll know what you're dealing with and what it will cost -- not wondering whether you'll be dealing with the same thing again in three months.
Your Household Keeps Running -- Whatever the Job Involves
Occasionally a camera investigation reveals something more serious than a simple blockage. A collapsed section of pipe. Significant root intrusion that requires excavation. A repair that will take time to plan and execute properly.
When that happens, the last thing your family needs is to be without working toilets while we sort it out.
We've handled exactly this situation. A sewer line beneath a home in Brunswick had completely separated underground. It wasn't a clean job -- but it was urgent. Rather than leaving the household without sewage function while we planned the full repair, we dug a hole just outside the kitchen window, temporarily cleared the blockage, and made the area safe and boarded up so the toilets could still be used. The family kept functioning normally while we organised and completed the proper repair.
"Even if it's a big job, we can find a quick solution for you while we fix the problem at the source." -- Sean Lawler
What Happens When You Call Integrity Plumbing About a Stormwater Problem
The Call
Tell us what you're seeing -- pooling water, overflowing gutters, a damp patch near the wall, whatever has prompted you to call. We'll ask a few questions and give you an honest read on what's likely involved. Stormwater problems aren’t always the same kind of emergency as a burst pipe -- but most are worth addressing before the next heavy rain, not after it. We'll tell you honestly how urgently we think you need to act and how soon we can get there.
The Site Visit and Camera Investigation
When we arrive, we map the full system before we touch anything -- where the stormwater lines run, where they connect, what each downpipe drains into. Then we camera the full pipe from the downpipes all the way to the street connection and show you exactly what we find. We also run water down each downpipe while we're on site to confirm what's flowing and what isn't -- because a camera shows the condition of the pipe, but running water shows how the whole system performs under load. You see everything we see, and we explain it in plain language before we give you a cost.
The Fix
Once we know what's causing the problem, we give you your options clearly. A high-pressure jet for root intrusion or buildup -- no digging required. Excavation and pipe repair for a collapsed or separated section. A rerouted drainage line for a property where the original installation was wrong. We explain what each option involves, what it costs, and what happens if you leave it. Then you decide.
Test, Clean Up, and Plan Ahead
Before we leave, we run the full system again to confirm everything is draining correctly. Any disturbed garden beds, turf, or soil is put back properly. We walk you through what we found and what we did. And if the nature of the problem means it's likely to return -- tree roots over the line, ageing clay pipe in a period home -- we'll tell you honestly and discuss whether a regular maintenance visit makes sense for your property. If a follow-up is needed, we confirm it with you and book it in before we go. You won't be chasing us.

Common Questions About Roof Leaks
For metal roofs -- Colorbond, corrugated iron, flat roof systems, and anything involving flashings -- a licensed plumber is the right call. Metal roof work falls under a plumbing licence in Victoria. Most roofers specialise in installing new roofs and generally won't return to investigate leaks on existing ones. If you've already called a roofer and been turned away or given an incomplete fix, a licensed plumbing team experienced in roof leak investigation is exactly what you need next.
Almost certainly because the actual entry point was never found. Water travels before it drips -- so the visible damage and the actual entry point are often in completely different locations. A repair that addresses the area above the stain rather than tracing the water back to its source will fail at the next rain event. Our investigation process starts at the symptom and traces back to the source before any repair work begins.
Yes. An intermittent leak is still causing damage every time it occurs -- to insulation, plasterboard, and potentially timber framing. And the fact that it only appears in heavy rain often means the entry point is a weather-folding or flashing failure that requires specific force to reveal itself. These are exactly the leaks most commonly missed by a quick visual inspection. They need a structured investigation, not a surface patch.
We know taking time off work for a trades visit is disruptive, so we'll always be straight with you about what a job involves. A straightforward repair -- a failed flashing, a cracked ridge cap, a single point of entry -- is usually completed in a single visit. On complex roofs with multiple issues, a second visit after the next rain event is sometimes needed to confirm everything is sealed. We'll tell you that honestly before we start -- not after.
Not necessarily -- and we won't tell you that you do unless it's genuinely the right answer. Many roof leaks can be repaired effectively with targeted work on the specific failure points. Where a roof is ageing and has multiple areas of concern, we'll give you an honest assessment of what targeted repair will achieve and what the longer-term outlook is -- so you can make an informed decision about repair versus replacement on your own timeline and budget.
It depends on what's causing it and how accessible the entry point is. A single flashing repair is significantly less involved than a job requiring multiple penetration reseals, ridge capping replacement, and weather folding correction across an entire roof section. We give you a clear cost before we start any significant work. What we tell you before we start is what you pay when we finish.
Tile roof repairs -- replacing broken tiles, repointing ridge caps -- sit outside the standard plumbing licence and are generally handled by specialist tile roofers. Where a tile roof is leaking at a flashing, penetration, or metal component, we can address that element. If the issue is with the tiles themselves, we'll tell you honestly and point you in the right direction rather than attempt work outside our expertise.
