How Long Does a Roof Replacement Take in Melbourne?
Most Melbourne metal re-roofs take 3 to 7 days — but weather, roof size, access and what's found underneath all move it. Here's an honest breakdown from a roof plumber.

“How long will it take, and how long will my house be pulled apart?” It’s one of the first things people ask when they’re weighing up a re-roof — fair enough, because a roof over your head isn’t something you want open to the sky for long. The honest answer is that most jobs are quicker than people fear, but a few things can stretch them out.
Here’s the real breakdown, so you can plan around it.
The quick answer
A typical Melbourne metal re-roof takes 3 to 7 working days. A straightforward single-storey house is often 3–4 days. A bigger or steeper home, a two-storey, or a job with lots of valleys, skylights and tricky access can run 5–7 days or more. Your house is never left exposed overnight — we only ever strip as much as we can make watertight before knock-off.
What a re-roof week actually looks like
- Day 1 — Set up and strip. Scaffold and safety rails go up, materials land on site, and we start pulling off the old roof — usually one section at a time so nothing’s left open.
- Days 2–3 — Out with the old, on with the new. Old sheets, battens and sarking come off; new sarking, battens (or top-hats) and flashings go on; then the new Colorbond sheets start going down.
- Days 4–5 — Flashings, ridges and detail. The bits that actually keep water out — ridge capping, valleys, barge flashings, penetrations around vents and skylights. This is where a good job is won.
- Final day — Gutters, clean-up and check. New gutters and downpipes if they’re part of the job, a full site clean (we magnet-sweep for stray screws), and a walk-around so you can see exactly what was done.
What makes it take longer
- Weather. Melbourne is the big one. We won’t strip a roof into a downpour, so a wet week can add days. It’s not padding — it’s keeping your house dry.
- Roof size and pitch. More area and steeper pitch means more time and more safety setup.
- Complexity. Lots of hips, valleys, skylights, chimneys and changes of level all add detail work.
- Access. A tight inner-city block, a two-storey, or no side access for a crane or rubbish bins slows the whole job down.
- What’s underneath. Once the old roof’s off, we sometimes find rotten timber battens or damaged rafters that need replacing before the new roof goes on. Better found now than roofed over.
The Melbourne-specific stuff
Our weather cuts both ways. It’s why re-roofs here can get weather-delayed — but it’s also why a proper job matters so much, because a Melbourne roof cops sideways rain and big temperature swings. On older inner-city terraces and period homes, box gutters and tricky access are the usual time-eaters. And if your place is heritage-overlay or body-corporate, there can be approvals to line up before we start — worth sorting early so the job itself runs clean.
Do you have to move out?
Almost never. It’s noisy during the day — there’s no way around footsteps and tools on your roof — but you can stay in the house the whole time. We work standard daytime hours, keep the site tidy, and make sure it’s watertight before we leave each day.
Frequently asked questions
Can a roof be replaced in one day? Only a very small, simple roof (like a carport or a tiny extension). A full house re-roof done properly is a multi-day job — anyone promising a whole house in a day is cutting corners on the flashings, which is exactly where roofs leak.
What happens if it rains during the job? We only strip what we can make watertight, so rain means we pause rather than expose your house. It can push the finish date out, but it protects the inside of your home — that’s the right trade.
Will my house be open to the weather overnight? No. Every day ends with the roof watertight. We never leave it open.
Does replacing the gutters add much time? Usually a day or less, and it’s the smart time to do it — the scaffold’s already up and the crew’s already there.
Planning a re-roof?
The best way to get a real timeline is a proper look at your roof — size, pitch, access and condition all feed into it. We’ll give you a straight estimate of both the cost and how long we’ll be on site, in writing.
