Roof Replacement Cost by Material
Material choice is the biggest single cost driver in roof replacement. Here’s what Melbourne homeowners are paying in 2026:
Concrete Roof Tiles
| Roof Size | Concrete Tile Cost | Notes |
|---|---|---|
| Small home (100–140 m²) | $10,000–$13,000 | Including removal and disposal of old tiles |
| Medium home (140–200 m²) | $13,000–$18,000 | Most common SE Melbourne home size |
| Large home (200–280 m²) | $18,000–$26,000 | Double storey or larger single storey |
Terracotta Roof Tiles
| Roof Size | Terracotta Tile Cost | Notes |

| Large home (200–280 m²) | $25,000–$35,000 | Includes hip-end and valley complexity |
Colorbond Steel Roofing

What’s Included in a Roof Replacement Quote
A proper roof replacement quote from a licensed Victorian roofer should include:
- Removal and disposal of existing roofing material (tiles, sheets, and nails)
- Inspection and replacement of damaged or rotten sarking (the foil membrane under tiles)
- Replacement of damaged battens or rafters (charged separately if significant)
- Supply and installation of new roofing material
- Re-bedding and re-pointing of ridge capping
- Installation or replacement of valley iron
- Gutter and downpipe check (replacement quoted separately)
- Rubbish removal and site cleanup
What Affects the Price
Roof Pitch and Complexity
A steeply pitched roof (over 30°) costs 20–30% more to work on safely — roofers must use roof anchors, harnesses, and scaffolding under WorkSafe Victoria regulations. Simple gabled roofs are cheapest. Hipped roofs (common in 1950s–1980s Berwick, Dandenong, and Frankston homes) have more hip-end complexity. Dutch gables and multiple valleys add further cost.
Roof Access and Scaffolding
Most Melbourne re-roofs require edge scaffolding under WorkSafe regulations — add $2,000–$5,000 for scaffolding hire (usually included in your quote; confirm this). Double-storey homes cost more to scaffold and take longer to erect safely.
Structural Repairs
Old homes in Dandenong, Frankston, and Cranbourne (built 1950s–1970s) sometimes have rotten fascia boards, damaged rafters, or corroded valley iron uncovered once tiles are removed. These repairs are charged on top of the base quote at $80–$150 per hour or per linear metre for timber, $120–$180 per linear metre for new valley iron.
Asbestos Roof Cement (Fibro Homes)
Pre-1990 fibro homes in SE Melbourne may have asbestos-cement ridge caps or valley flashings. These require licensed asbestos removal before roofing can proceed — add $800–$3,000 depending on quantity, under Victoria’s Occupational Health and Safety Regulations.
Repair vs Replace: When Replacement Makes More Sense
| Roof Age / Condition | Repair Cost | Recommendation |
|---|---|---|
| Under 20 years, isolated damage | $300–$1,500 | Repair — replacement not justified |
| 20–30 years, multiple leaks | $2,000–$5,000 ongoing | Get replacement quote — repair costs may exceed value |
| 30+ years, widespread cracking or mortar failure | $4,000–$8,000 ongoing | Replace — repairs are temporary, replacement is the better investment |
| Any age, >30% of tiles broken or displaced | $5,000+ ongoing | Replace — economics clearly favour new roof |
Signs You Need a Roof Replacement (Not Just Repair)
- Visible daylight from inside the roof space when standing in the ceiling cavity
- Widespread ridge mortar failure — mortar crumbling between most ridge tiles
- Multiple active leaks in different locations after rain
- Roof surface older than 40 years for concrete tiles, 25 years for corrugated iron
- Roof sags or bounces when a roofer walks across it (rafter or batten failure)
- Insulation in ceiling cavity is repeatedly getting wet (sarking has failed)
How to Choose a Roofer in Melbourne
Under Victorian law, any roofing work valued over $10,000 requires a registered building practitioner (RBP), not just a general plumber’s or builder’s licence. Check your roofer’s registration at VBA.vic.gov.au. Ask for their Domestic Building Insurance (DBI) certificate — insurance is compulsory for works over $16,000 in Victoria and protects you if the roofer goes bankrupt mid-job or the work is defective.
Top 10 Tips and Gotchas
- Get 3 quotes minimum. Melbourne roofing quotes can vary by 20–40% for the same scope. Make sure each quote covers identical materials and scope before comparing.
- Check for Domestic Building Insurance on jobs over $16,000. Compulsory in Victoria — ask for the DBI certificate number before signing.
- Avoid cash-only quotes. Legitimate roofing businesses issue tax invoices and take deposits via bank transfer, not cash only. Cash-only roofers may not be licensed or insured.
- Ask what battens are included. Some quotes include batten replacement; others don’t. Damaged or under-spec battens found during tile removal are added as variations — get clarity upfront.
- Colorbond colour choice matters for resale. Neutral colours (Surfmist, Basalt, Ironstone) have broad appeal. Bright or unusual colours may limit your buyer pool in SE Melbourne’s owner-occupier market.
- Check the sarking specification. Cheaper quotes may omit upgraded sarking. Sisalation foil sarking reduces heat transfer into the ceiling space — worth specifying in SE Melbourne’s hot summers.
- Budget for gutter replacement if the roof is old. If your tiles are 30+ years old, the gutters are probably the same age. Replacing both at once saves on scaffolding costs.
- April–September is better for scheduling. Summer and post-storm periods create backlogs of 6–12 weeks. Autumn and winter allow 2–4 week scheduling and occasionally better pricing.
- Asbestos ridge caps are common in pre-1990 homes. Don’t assume your home is asbestos-free — have a licensed assessor check before your roofer starts if the home is pre-1990.
- Take before and after photos. Document the existing condition and the completed work for your home insurance records and any future sale disclosure requirements.

FAQ
How long does a roof replacement take in Melbourne?
Most residential roof replacements take 2–5 days depending on size and complexity. A simple single-storey Colorbond re-roof takes 2–3 days. A large hipped terracotta tile roof takes 4–7 days including scaffolding erection and dismantling. Weather delays are common — Melbourne’s changeable spring and autumn weather can add 1–3 days to any job.
Is roof replacement covered by home insurance in Victoria?
Home insurance covers sudden damage (storm damage, falling trees, hail impact) but not gradual deterioration. If your roof has failed due to age and wear, insurance won’t cover replacement — that’s owner’s maintenance. If a storm caused discrete damage to an otherwise sound roof, insurance typically covers repairs or replacement to that affected area only.
Can I stay in my home during a roof replacement?
Yes, in most cases. The property remains habitable, though noisy. Some homeowners prefer to stay elsewhere for the noisiest days. If structural repairs or extensive decking work are needed alongside the re-roof, the roofer will advise. Organise pets to be elsewhere during work — falling tiles and roofer foot traffic are stressful for animals.
Do I need council approval for a roof replacement in Victoria?
No permit is required to replace a roof with the same material on a standard residential property. If you’re changing the roof profile, raising the pitch, or adding roof penetrations (skylights, solar panels) you may need a building permit. Heritage overlay properties in some Melbourne suburbs may require council approval even for like-for-like replacement — check with your council’s planning department.
What’s the warranty on a new Colorbond roof in Melbourne?
BlueScope’s Colorbond Ultra steel carries a 35-year warranty against perforation and a 15-year paint warranty. The installation workmanship warranty is separate and provided by your roofer — ask for a minimum 7-year workmanship warranty on ridge capping and flashing, which are the most common leak points post-installation.
Final Thoughts
A roof replacement is one of the largest single investments Melbourne homeowners make — but it’s also one that adds directly to property value and eliminates ongoing repair costs. Getting at least three quotes from VBA-registered roofers, confirming Domestic Building Insurance on jobs over $16,000, and specifying quality sarking are the three steps that separate a good outcome from a stressful one.
In SE Melbourne’s competitive property market, a new roof is a significant selling point. A Colorbond re-roof on a Berwick or Narre Warren home typically adds $15,000–$25,000 to asking price — comparable to the cost of the work itself.
