Roof Leak Repair Melbourne, Fixed at the Source

"Fast response time, quality work and doesn't muck around. Has handled a variety of plumbing jobs for myself and friends and is a roof leak specialist. Highly recommended."
— Steven Vassallo

Chasing a roof leak repair Melbourne trades keep missing? Integrity Plumbing finds the real source of the leak and fixes it properly, first time. 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.

icon34

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.

icon35

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.

icon36

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.

Roof Leak? Call Sean and His Team for a Straight Answer.

Tell us what you're seeing -- the stain, the bubbling plaster, the damp smell after rain -- and we'll give you an honest assessment of what's involved and how quickly we can get there. No pressure. No overselling. Just straight advice from a team that's been solving Melbourne's harder plumbing problems since 2008.

You’ll speak with Sean, the plumber, not a booking agent reading from a script.

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

The Damage Is Compounding While the Leak Goes Unfixed

Why Integrity Plumbing Finds the Leaks Others Miss -- And What That Means for You

We Investigate Before We Touch Anything

The most expensive mistake in roof leak repair is patching the wrong spot. It costs you the call-out, the labour, and the materials -- and leaves the leak completely intact. The stain dries out, you think it's fixed, and then the next downpour proves otherwise.

We don't patch until we know exactly where the water is entering. That means inspecting the whole roof -- every flashing, every penetration, every ridge cap, every point where the roof meets a wall or another structure -- before a tube of sealant is opened. On jobs where the water path isn't visible from above, we use thermal imaging cameras to trace moisture back through the ceiling structure to its source. We show you what the camera finds -- the moisture path, the entry point, the extent of the damage -- so you understand exactly what's happening before we quote a dollar of work.

Most plumbers carry a ladder and sealant. We carry the equipment that finds the leak rather than guesses at it.

We've Seen This Before -- Which Means We Know Where to Look

Sean estimates that only about 20--30% of licensed plumbers can diagnose a roof leak properly -- even though most hold the licence to do the work. The difference isn't the licence. It's knowing, from experience, which failure is causing which symptom.

The flashing that's lifted slightly at a wall junction and is only letting water in when rain is wind-driven. The ridge cap that looks intact from the ground but has lost its seal underneath. The roof sheet ends that were never weather-folded and only fail when the rain is heavy enough to drive water upward over the edge. These are the failures that a quick visual inspection misses -- and that thermal imaging and a structured process finds.

That experience is what you're paying for when you call Integrity. Not just a tradesperson on your roof, but a team that has diagnosed this kind of problem before and knows exactly what to look for. That's what The Cause-First Diagnostic means on a roof job -- not a visual scan and a tube of sealant, but a structured process built on knowing which failure causes which symptom.

On Complex Jobs, We Tell You What to Expect -- Before You Find Out the Hard Way

A plumber who guarantees a single-visit fix on a multi-point leak without a full investigation hasn't done one. We'd rather be straight with you upfront than have you caught out after the next storm. 

A roof with multiple leak points sometimes reveals itself in stages. Fix the most obvious entry point and the next rain event shows you there was another one the first repair was masking. 

If we’re not certain everything is resolved before we leave, we’ll tell you.

The Practical Promises -- Because How We Work Matters as Much as What We Fix

Finding the leak properly is the main event. But the experience of having a trades team in and around your home matters too -- and it's where a lot of plumbers fall short.

We turn up when we say we will. For a roof leak job -- where you've taken time off work or rearranged your day to be home -- that's not a small thing. We know your time is valuable and we treat it accordingly.

We keep your home the way we found it. Roof work means time on your roof, access through your ceiling cavity, and movement through your home. We use floor protection on internal access, take care around your ceiling and cornices when working above them, clean up thoroughly, and close everything up properly before we leave. You won't be left with an open manhole and a mess to deal with. 

We communicate throughout. When we find something on the camera, we show you. When the repair is done, we walk you through what we did and why. You'll never be left wondering what happened on your roof or why the invoice says what it says.

And all our work is backed by a lifetime workmanship guarantee. If something we repaired isn't right, we come back. First call. No argument.

A Clear Picture of What's Wrong -- And Honest Options for Fixing It

Once we know what's causing the leak, we give you a clear picture of what fixing it properly involves and what it will cost. And we give you a genuine choice.

On a straightforward job -- a failed flashing, a cracked ridge cap, a single entry point -- the repair is targeted and can usually be completed the same day. You'll know exactly what was wrong, what we did, and why it won't happen again.

On a more complex roof -- one that's ageing, has multiple issues, or where a targeted repair is the right answer now but replacement is the right answer eventually -- we'll tell you that honestly. We'd rather give you the full picture and let you plan than patch it three times over two years and charge you each time. 

Sean did exactly this for a client who had just purchased a home with a leaking extension roof. The investigation revealed not just the active leak but several additional issues on a roof that was approximately 30 years old. He gave the client two options -- a repair within their current budget that addressed the active leak, and an honest recommendation to plan for full replacement down the track. The client knew exactly what they were getting and what to plan for. No surprises. No pressure.

That's the conversation you should be having with your plumber.

No Guessing. No Patching the Wrong Spot. Here's Exactly What We Do

  • icon07

    The Call

    Tell us what you're seeing -- the stain on the ceiling, the bubbling plaster, the damp smell after rain, water appearing inside the house during a storm. We'll ask a few questions about the roof type, the age of the home, where the symptoms are appearing, and whether it happens in all rain or only heavy downpours. Those details help us understand what we're likely dealing with before we arrive. We'll tell you exactly when we can be there and what to expect when we arrive.

  • icon08

    The Investigation

    When we arrive, we investigate before we touch anything. We inspect the full roof -- not just the section above the stain -- checking flashings, ridge capping, penetrations, lap joints, sheet ends, and every point where the roof meets another structure. Where the water path isn't obvious, we use thermal imaging to trace moisture back to its source. We don't start any repair work until we're confident we've found the actual entry point. And we explain what we're finding as we go -- showing you the thermal camera footage, pointing out what we're seeing, and telling you in plain language what it means.

  • icon20

    The Options

    Once we know what's causing the leak, we give you a clear picture of what fixing it properly involves and what it will cost -- before we start any work. With a straightforward job, we can usually complete the repair on the same day. On a more complex roof, we'll give you a realistic assessment of what targeted repair will achieve, what the longer-term outlook is, and whether a full replacement is something to plan for down the track. You make the decision with full information.

  • icon21

    The Repair

    We complete the repair using quality materials and proper technique -- not a quick bead of sealant over a symptom. Where flashings need replacing, we replace them properly. Where ridge capping needs repointing or replacing, we do it correctly. Where sheet ends need weather folding, we fold them. The repair is done to last -- not to get through the next few rain events. And it's backed by our lifetime workmanship guarantee. If something we repaired isn't right, we come back. First call. No argument.

  • icon21

    The Follow-Up

    Before we leave, we walk you through exactly what we found, what we did, and what -- if anything -- you should keep an eye on. On complex roofs where we've identified multiple issues, we'll tell you honestly if a follow-up visit may be needed after the next heavy rain gives us the chance to verify everything is sealed. If it is, we book it in before we go. You won't be chasing us.

Common Questions About Roof Plumbing and Leaks

Common Questions About
Roof Plumbing and Leaks

Should I call a roofer or a plumber for a roof leak?

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.

Why did my roof leak come back after it was already repaired?

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.

My roof only leaks in really heavy rain. Does it still need fixing?

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.

How long will the repair take?

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.

Will I need a full roof replacement?

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.

How much does a roof leak repair cost?

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.

Can you repair tile roofs as well?

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.
