How Much Does a Roof Replacement Cost on the Mornington Peninsula?
A full roof replacement on a typical Peninsula home is $18,000 to $28,000 in Colorbond steel or $22,000 to $35,000 in tile. Most residential re-roofs take 2-5 working days; weather, a complex roof or structural repairs can stretch a job to 5-10. Four things move the price:
- Roof size. A larger roof means more to remove and more new roofing, sarking and insulation.
- Pitch and access. Steep pitches and hard-to-reach roofs take longer to strip and re-roof safely.
- Condition. The framing is inspected once the old roof is off, and any structural repairs are done before the new roof goes on.
- Material. Colorbond or Zincalume sheeting, or tile, plus the insulation and ventilation that suit the home.

Roof Replacement Across the Mornington Peninsula
Where a home sits on the Peninsula changes how its new roof should be specified. On the bayside, from Mount Eliza and Mornington down through Mount Martha, Dromana and Rosebud, salt air off Port Phillip is the main enemy of old roofs, so corrosion-resistant hardware and the right sheet for the home's distance from the water matter. Around Sorrento and Flinders, roofs also take stronger winds off the ocean, so fixing densities and flashings are set for that exposure. Inland and in the northern suburbs, such as Carrum Downs and Cranbourne, salt is less of a factor and the usual reasons to replace are tile fatigue, chronic leaks or a renovation.
In every part of the Peninsula, a common choice is a tile-to-metal conversion: the old tiles come off, the framing is checked and repaired, and Colorbond or Zincalume goes on over new sarking and insulation. Local detail is on the suburb pages for roof replacement in Mornington, roof replacement in Mount Martha, roof replacement in Frankston and roof replacement in Cranbourne.

If the roof is still sound, roof restoration on the Mornington Peninsula may be the better-value option, and one-off leaks are usually a job for roof repairs.
When to replace a roof
- Widespread rusting, corrosion, or tile fatigue affecting multiple areas
- Chronic leaks despite repeated patching and repairs
- Major renovations where improved insulation, sarking, and a fresh look are desired
- Structural changes requiring modified roof lines or additional load capacity
- Energy efficiency upgrades to reduce heating and cooling costs
- Storm damage that makes replacement more economical than extensive repairs
Material options
We specialise in Colorbond and Zincalume metal re-roofing, as well as tile-to-metal conversions. Modern metal roofing offers superior durability, weather resistance, and lower maintenance compared to traditional materials.
Our installations include proper roof blanket insulation, reflective sarking, and ventilation systems designed for Peninsula conditions. This combination delivers excellent thermal performance and condensation control — crucial for coastal homes.
Our process
We begin with careful removal and disposal of existing roofing materials, followed by thorough inspection of roof framing. Any structural repairs are completed before installing modern sarking, insulation, and the new roofing system.
Each installation includes proper flashings, fixings rated for local wind conditions, and detailed weatherproofing around penetrations. We work systematically to maintain weather protection throughout the project.
Insulation and comfort
A re-roof is the perfect opportunity to upgrade insulation and ventilation. We install bulk insulation (typically R1.8 to R2.5), reflective sarking, and adequate ventilation to create a comfortable, energy-efficient home.
Proper insulation dramatically reduces heat transfer, keeping homes cooler in summer and warmer in winter while reducing rain noise — a common concern with metal roofing.
Roof replacement on the Mornington Peninsula: common questions
Which Mornington Peninsula suburbs do you replace roofs in?
The whole Peninsula and the suburbs around it, including Mornington, Mount Martha, Mount Eliza, Frankston, Dromana, Rosebud, Sorrento, Flinders, Seaford, Carrum, Carrum Downs, Cranbourne and Hampton.
What does a roof replacement include?
Removal and disposal of the old roof, an inspection of the roof framing with any structural repairs, new sarking and insulation, then the new roof with its flashings, fixings and weatherproofing around penetrations. The roof is made watertight at the end of each day.
Can you replace a tiled roof with Colorbond?
Yes. Tile-to-metal conversions are one of the main re-roofing services on the Peninsula. The tiles come off, the framing is checked for the new roof, and Colorbond or Zincalume sheeting goes on over new sarking and insulation.
Should I replace my roof or restore it?
If the tiles or sheets are still sound and the problem is faded coatings, moss or worn pointing, a restoration is usually the better-value option. Replacement makes sense when rust, corrosion or tile fatigue is widespread, or leaks keep coming back after repairs.

Clarify what sits outside a roof replacement scope
Updated
Before approving roof replacement, ask which adjoining items are included and which are separate. Gutters, downpipes, insulation, solar equipment and internal ceiling repairs may need coordination, but they are not automatically included in every replacement quote. A written scope should identify the boundary clearly.
Ask how unexpected deterioration will be handled after old material is removed. The contractor should explain the finding and any proposed variation before extra work is approved. An allowance for concealed conditions differs from a fixed price covering a fully established scope.
Confirm access, deliveries, disposal and temporary protection arrangements. If the home remains occupied, ask how work stages and interruptions will be communicated. Compare the proposed material and included components rather than the total alone. Keep the final scope, exclusions and variation process with the quote so you can understand what the agreement covers. Those details are useful when coordinating other trades and checking the handover at the end of the job.
Plan access and site protection for an occupied home
Updated
If the home will remain occupied during roof replacement, ask for a site-access plan before agreeing on a start date. Discuss which entrances can remain in use, where materials and waste will be placed and how residents will be kept away from the work area. Delivery access and safe pedestrian access need to be considered together.
Tell the contractor about children, pets, mobility needs and anyone working from home. Identify shared driveways, neighbouring access rights and places that cannot be obstructed. Ask who will coordinate other trades and communicate changes if the planned sequence is interrupted. Residents should not move scaffolding, barriers or stored roofing materials to make a route through the site.
Confirm how the building will be protected during each work stage and who to contact if circumstances change outside working hours. Weather and findings after removal may affect the sequence, so ask how updates and any revised arrangements will be communicated rather than relying on a fixed completion promise. Keep the access and protection plan with the accepted quote. The re-roofing page explains the broader replacement enquiry.
