A leaking roof isn't something you can ignore. Whether you've noticed a stain spreading across your ceiling or heard dripping sounds during rain, a leak demands attention - fast. The good news is that most roof leaks are repairable, and with the right approach, you can stop the damage before it becomes expensive.
At Leaky Roof, we've spent years helping Canberra homeowners and businesses fix roof leaks before they turn into major problems. This guide walks you through what a typical leak repair looks like, how to recognise when you need professional help, and what to expect from start to finish.
Roof leaks rarely announce themselves with a dramatic downpour inside your living room. Most begin quietly - a small gap in the flashing, a cracked tile, a blocked gutter, or degraded sealant around a vent. Water finds its way in, often travelling along beams or under insulation before it shows up on your ceiling.
The longer a leak goes unrepaired, the more damage it does. Water stains spread, timber softens, insulation loses its effectiveness, and you risk mould and structural harm. That's why early detection and quick repair matter so much.
Watch for these common warning signs:
Interior stains and marks. Brown or yellowish patches on ceilings or walls are the classic signal. They may appear after heavy rain or grow slowly over weeks.
Soft spots or spongy timber. If you can safely access your roof space or fascia, feel the timber around gutters and edges. Soft, damp wood is a red flag.
Mould or musty smells. A damp, musty odour in your home - especially in bedrooms, bathrooms, or near rooflines - often points to moisture entering from above.
Sagging gutters or visible damage. Gutters pulling away from the fascia, rusted sections, or cracks are visible leak risks. Damaged tiles, lifted metal sheeting, or cracked flashing also need attention.
Water in the roof space. A quick look into the roof space after rain might reveal damp spots, wet insulation, or water stains on the underside of roofing material.
Daylight coming through. If you can see daylight from inside the roof space, water can get in too.
A typical leak repair for a single-storey home in Canberra ranges from $1,400 to $2,500 (including GST). Minor fixes - like re-sealing a vent or replacing a cracked tile - can cost a few hundred dollars. The final cost depends on:
We always recommend a professional inspection before committing to a repair price, so you know exactly what you're dealing with.
Before any repair, a roofer needs to find the leak's source - not just where water is showing up inside. Water often travels some distance before it appears, so the entry point might be nowhere near the stain on your ceiling.
Our roof inspection costs $99 (including GST) and includes a comprehensive assessment, detailed photos, a written report, and a quotation for any repair work. This fee gives you certainty about what's wrong and what it will cost to fix.
If you'd prefer a quick, no-pressure chat first, we also offer a free roof estimate - a 30-minute conversation where we can discuss your situation and recommend the best next step.
Once we've identified the leak, we'll provide a clear quote outlining:
We're transparent about pricing and happy to explain why the repair costs what it does. If you'd like time to think it over, that's completely fine - get back to us whenever you're ready.
Most leak repairs can be scheduled within 1-2 weeks. On the day, we'll arrive with the materials and tools needed, complete the work, and make sure the site is left clean and tidy. A typical repair takes anywhere from a few hours to a full day, depending on complexity.
We test the repair during work and before we leave. All of our roofing work comes with a 5-year workmanship guarantee, so if something isn't right, we'll put it right.
Sometimes what looks like a single leak is actually a sign that your roof is near the end of its life. If your roof is 20+ years old, has multiple leaks, or sustained storm damage, a repair might be a temporary fix.
In those cases, we'll be honest about it. A roof restoration (which cleans, re-seals, and strengthens your existing roof) or a full replacement might be the better investment.
Roof restoration costs between $11,000 and $18,000 for a concrete tile roof, $12,500 to $20,500 for terracotta, and $5,500 to $9,500 for metal or Colorbond. It extends your roof's life by 10-15 years.
Complete re-roof (full job, including new materials and installation) ranges from $32,500 to $54,000 for concrete, $49,500 to $82,500 for terracotta, and $34,000 to $57,000 for Colorbond. It gives you a new roof with a long lifespan and a fresh warranty.
Our team can advise you on whether repair or replacement makes sense for your situation.
Once your leak is fixed, simple maintenance goes a long way:
Keep gutters clean. Blocked gutters overflow and force water under your roof line. We offer gutter cleaning from $250 to $450 (including GST), depending on your roof size and complexity.
Inspect after storms. Heavy wind and hail can dislodge tiles or damage flashing. A quick look (or a call to us) after severe weather can catch problems early.
Trim overhanging trees. Branches rubbing on your roof wear it down, and leaf litter blocks gutters.
Consider a gutter guard. These prevent leaves and debris from blocking your gutters, reducing maintenance and leak risk.
Join a Roof Care Package. Our membership plans start from $59 per month and include scheduled inspections, priority booking, and repair discounts. It's peace of mind without the stress of remembering to check your roof yourself.
