When water isn’t draining where it should, the damage rarely stays on the roof. Overflowing gutters, blocked downpipes and failing box gutters send water into ceilings, walls and foundations – often long before you notice a stain.
Reliable Roofing Group are licensed roof plumbers who handle the full rainwater system: capturing, channelling and carrying water safely away from your home. We diagnose the real cause, fix it to code, and leave you with a roof that manages water the way it’s meant to.
Roof plumbing covers everything that moves water off and away from your roof. When any part of that system fails, water finds its way inside. Here’s what we fix – and what’s involved.
Clearing, realignment, re-pitching and gutter guard installation to restore proper flow.

A stain on the ceiling is almost never where the problem starts. Water travels – along flashings, down valleys, through blocked gutters – before it shows up inside. We trace it back to the real source.
That means checking how the whole system moves water: whether the gutters are pitched correctly, whether the box gutter has the capacity for a heavy Melbourne downpour, and whether the flashings are still doing their job. Fix the cause once, and you stop paying to patch the symptom again and again.

Roof plumbing is one part of what we do. Explore our full range of roofing services.
A roof plumber specialises in the rainwater system on and around your roof – gutters, downpipes, box gutters, flashings, valleys and stormwater connections. It’s a licensed specialty separate from general plumbing, and in Victoria this work must be carried out by a licensed roof plumber to meet compliance standards.
If you’re seeing water stains on ceilings after heavy rain, overflowing gutters, damp near downpipes, or water pooling around the foundations, it’s almost always a roof plumbing problem – usually blocked, undersized or failing drainage rather than the roof covering itself. We trace it to the source before recommending any work.
At least once a year, and ideally before Melbourne’s wetter months. Homes with overhanging trees should check more often, as leaf litter is the most common cause of blockages and overflow. A quick annual service is far cheaper than repairing water damage.
Box gutters sit within the roof structure, so any overflow goes straight into the ceiling. It’s usually caused by blockages, poor original sizing, or a failed lining. We assess capacity and either re-line or upgrade the box gutter so it can handle Melbourne’s heavy downpours.
Yes. Where required, we provide the relevant compliance documentation for work completed to Australian Standards (AS/NZS 3500), giving you certainty the job is done to code – useful for insurance, records and future sale.
For active leaks we prioritise a fast response, often same-day or next-day, to stop further water damage. Get in touch and we’ll book you in as a priority.
