2. What Affects the Cost of a Roof Replacement
Several factors can influence the total price:
Roof size and pitch: Steeper or multi-level roofs require extra scaffolding and labour.
Roofing material: Colorbond® and Zincalume® roofs cost more upfront but offer long-term durability and energy efficiency.
Accessibility: Tight driveways or fragile tiles increase set-up time.
Existing condition: Damaged battens, insulation or guttering may need attention during the reroof.
3. Ways to Save on Your Reroof
Bundle work together – Replace gutters and flashings at the same time to reduce labour costs.
Choose long-life materials – Quality metal roofing can last 40 + years with minimal maintenance.
Act early – Delaying replacement can lead to costly structural damage beneath the roof.

Roof Replacement Cost FAQs
How much does a roof replacement cost in Perth?
A full roof replacement on a standard single-storey Perth home costs between $25,000 and $70,000. Where you land in that range depends on the roof material being removed, the size and pitch of the roof, access to the property, and the condition of the structure underneath. Larger or two-storey homes typically start from $60,000.
How much does it cost to replace a tile roof with Colorbond in Perth?
A tile to Colorbond conversion, also called a tile to tin or tile to metal roof conversion, typically costs between $30,000 and $60,000. This is the most common re-roof we complete in Perth. Metal is significantly lighter than tile, so the existing roof frame usually supports the new roof without structural upgrades, though the battens and timbers still need to be sound.
How much does it cost to replace an asbestos roof in Perth?
An asbestos to Colorbond conversion typically costs between $35,000 and $70,000. The premium over a tile conversion covers licensed asbestos removal, higher disposal fees at a licensed facility, site containment and PPE, and the WorkSafe WA notification process.
How much does it cost to replace an existing metal or tin roof in Perth?
A tin to tin replacement, where an old or corroded metal roof is replaced with new Colorbond sheeting, typically costs between $25,000 and $50,000. This is usually the least expensive of the three conversion types because there is no heavy tile removal and no licensed asbestos handling involved.
Why does an asbestos roof cost more to replace than a tile roof?
The difference is compliance cost, not margin. Asbestos removal must be carried out by a WorkSafe WA licensed Class B removalist, the waste must be wrapped, manifested and taken to a licensed disposal facility at a materially higher tipping rate than clean construction waste, and the job requires containment, wetting down and single-use equipment. WorkSafe must also be notified at least five days before removal begins.
What makes one roof replacement quote higher than another?
Roof area and pitch, whether the home is single or two storey, scaffolding requirements, access for skips and vehicles, the condition of battens, purlins and structural timbers, the Colorbond profile and colour selected, insulation specification, whether gutters and downpipes are being replaced, and whether solar panels need removing and reinstating.
Is a roof replacement quote fixed or can the price change during the job?
Our quotes are fixed. We assess the roof and its structural condition before quoting rather than after, so the price is not adjusted once the old roof comes off. If something genuinely unforeseeable emerges, we tell you before proceeding and you approve it in writing. Be cautious of any roofing quote carrying an uncapped provisional sum for structural works.
Do you charge for a roof inspection or quote in Perth?
No. Both the initial estimate and the on-site assessment are free with no obligation. We carry out full roof replacements only, so if your roof does not need replacing yet we will tell you.
