What a Roof Replacement Costs in Queensland

Replacing a roof is the largest single piece of work most Queensland houses ever have done to them, and the price range is wide enough to be genuinely confusing. Laying new sheets over battens that are still sound comes in at $70 to $130 the square metre. Taking concrete tiles off and putting metal on costs $110 to $190, because the battens, the fastener pattern and sometimes the tie-down connections all have to change at the same time. Putting new tiles back on a tiled roof sits at $90 to $160, and terracotta at $130 to $230. Scaled up to a conventional 200 square metre house, the three routes come out at roughly $14,000 to $26,000, $18,000 to $32,000 and $22,000 to $38,000 respectively.

Those bands are honest averages and they hide the three things that actually decide a quote. The first is where the house sits, because a roof in Cairns or Townsville is fixed to a cyclonic specification that a roof in Toowoomba is not, and the extra fasteners, washers and tie-down work add $15 to $40 the square metre before anybody chooses a colour. The second is what comes off before the new roof goes on, and asbestos cement sheeting or a solar array can each add thousands. The third is the shape of the roof itself, since a simple gable prices at the bottom of every band and a two storey Queenslander with hips, valleys, dormers and a steep pitch can run forty per cent above it.

It is also worth being clear about what a replacement is not. It is not the right answer to a roof that leaks in one spot, and roof repairs will deal with that for a tiny fraction of the money. It is not the right answer to tiles that have simply lost their surface colour, where roof restoration at a quarter of the cost buys another fifteen years. Replacement earns its money when the substrate itself is finished, when the fixing system no longer meets the wind load the house needs to resist, or when the material has reached an age where repairs stop holding. The first of those is the easiest to recognise from inside the house. Multiple unrelated leak points almost always mean the system has gone, not a single component.

The sections below work through the restore-or-replace decision, the full rate card, wind classification and why it matters so much in this state, what changes when a tile roof becomes a metal one, the approvals and certificates a Queensland re-roof needs, the two items that most often blow a budget apart, how prices move around the state, and what a quote has to show before it can be compared. Where this sits inside a wider project, the roofing services page covers the trades that work alongside a re-roof.

Restoration, Repair or Replacement

Three different jobs get called the same thing by homeowners and sometimes by salespeople, and they differ by a factor of four in price. A repair fixes a defined fault, usually a few square metres of it. A restoration cleans, repairs and recoats a roof that is structurally sound but has lost its surface, and on tiles it includes rebedding and repointing the ridge capping. A replacement strips the roof covering back to the battens or further and puts a new one on. Knowing which of the three a quote is actually offering is the first thing to establish. The words get used interchangeably and the prices do not.

The test is whether the substrate has failed or just the surface. On a tiled roof, individual tiles crack, ridge capping cracks and lets water in, valley irons rust through, and pointing fails. All four of those are repairable, and a roof with sound tiles and failed pointing is a restoration candidate at $45 to $90 the metre for the ridge work. A roof where the tiles themselves have gone porous, where a significant proportion are cracked, or where a terracotta roof has lost its glaze across whole planes, is past that point. Porosity is the test that matters, because a tile that absorbs water no longer sheds it. A simple check is whether the tiles stay dark for hours after rain.

On a metal roof the equivalent question is where the corrosion is. Surface rust on the top of a sheet, particularly around fasteners, is cosmetic and can be treated and coated. Corrosion from the underside, which happens where sheets have been laid without sarking over a damp roof space, or at the laps where water sits, eats through the sheet from the side you cannot see. When a screwdriver goes through a sheet with hand pressure near a lap, the roof is finished.

The honest economics favour restoration whenever it is genuinely available. A tile restoration on a 200 square metre house runs $5,500 to $11,000 against $18,000 to $32,000 for replacement, and a good one buys twelve to twenty years. Our roof restoration page covers that work and roof painting covers the coating side of it. Where only part of the roof has failed, targeted work is better value again.

Three situations push the answer to replacement regardless of surface condition. The first is a roof that leaks in multiple unrelated places, because that pattern says the system itself has failed. The second is a roof whose fixing no longer suits the wind load the building has to resist, which matters enormously in this state and is covered in its own section below. The third is asbestos cement sheeting, where there is no restoration option worth having and the sensible plan is removal. Coating over cement sheeting postpones the problem and adds to the eventual cost of it. The coating itself becomes contaminated material at removal time.

Age on its own is a weak signal and gets overused in sales conversations. A Colorbond roof fixed correctly in a mild inland location can run forty years and still be sound. A cheap unsarked metal roof in a coastal suburb can be finished in eighteen. Terracotta tiles last the better part of a century while their pointing needs redoing three or four times across that span. The condition of the material in front of you is the only reliable guide.

One practical step settles most of these arguments cheaply. A roof inspection with a written report and photographs costs $300 to $750, and it gives a condition assessment from somebody with no interest in the outcome if you engage an independent inspector in place of a roofing contractor. Our building inspection page covers the people who carry out that kind of assessment. Walking the roof yourself is a poor idea on tiles and a worse one on an old metal roof. Concrete tiles crack under a misplaced step and corroded sheeting gives way without warning. The report is cheaper than either outcome.

Roof Replacement Costs by Scope Item

The table below is organised by what each line is buying instead of by trade, because a roof replacement quote arrives as a single figure and the useful question is what that figure contains. Rates are for a south east Queensland job on a single storey house with reasonable access, and the final column names what is commonly excluded or charged separately on each line, which is where the variations come from.

Read the per square metre figures against the roof area and not the floor area. A single storey house with a 180 square metre floor plan and a hipped roof at 22 degrees has roughly 210 to 230 square metres of roof surface once the pitch and the eaves overhang are counted. Quotes are priced on the roof area, so a quote that quietly uses the floor figure will be short by fifteen to twenty per cent.

Battens are the line on a quote that is most often misunderstood. Relaying metal over existing battens is only possible where those battens are sound, correctly spaced for the new profile and able to take the fixing load for the wind class. Tile battens are spaced for tiles and are the wrong spacing for most metal profiles, which is why a tile-to-metal conversion almost always includes new battens at $25 to $55 the square metre.

Disposal is a real number on this job and it should appear as its own line. A 200 square metre concrete tile roof is something like twelve to fourteen tonnes of material coming off, which is several truck loads or a run of heavy bins at $450 to $1,400. Old metal roofing has scrap value and sometimes offsets its own removal, which is a reasonable thing to ask about. Our skip bin hire and rubbish removal pages cover the disposal side. Bin weight limits become relevant quickly with concrete tiles. Several smaller bins are often cheaper than one that goes over its allowance.

Two lines in that table are not optional despite often being presented that way. Sarking or an insulation blanket under a new metal roof at $12 to $30 the square metre is what manages condensation, cuts radiant heat and reduces rain noise, and leaving it out to win a quote is a false economy in this climate. Replacing fascia and gutter at the same time at $75 to $160 the metre costs far less than doing it two years later, because the access and the roof edge are already open.

Wind Classification and Why It Decides the Price

This is the part of a Queensland roof replacement that has no equivalent in most other states, and the single largest technical driver of cost. A roof is not primarily holding itself down against gravity. It is resisting uplift, because wind flowing over a roof creates suction above it and pressure inside the building below it, and the net force on a windward roof plane in a severe event pulls upward hard enough to peel a sheet off its battens and the battens off the rafters.

How hard it pulls depends on where the house is. The wind loading standard divides Australia into regions, and Queensland straddles the boundary between the non-cyclonic and cyclonic ones. Broadly, the south east corner, the Darling Downs and the inland south sit in non-cyclonic territory, while the coastal strip from around Bundaberg northward to Cape York, extending a substantial distance inland, sits in the cyclonic region. The design wind speeds either side of that line are not slightly different, they are a different order of problem.

For housing, that gets translated into a site wind classification under the wind loads for housing standard, which produces a class from N1 to N6 in non-cyclonic areas and C1 to C4 in cyclonic ones. The classification depends on the regional wind speed, the terrain category, how shielded the house is by surrounding buildings and vegetation, and its topographic position on a hill or in a valley. Two houses in the same street can land on different classes if one sits on a ridge and the other in a hollow.

The classification is a working specification and not a formality. It determines the screw pattern on the roof sheeting, whether cyclone washers or load spreading washers are required under the fasteners, the batten size and spacing, and the strength of every connection in the tie-down path from the sheet through the batten to the rafter, to the top plate, down the wall and into the footing. In cyclonic regions the sheeting and fasteners also have to have been tested for fatigue under repeated load cycling, because a cyclone loads a roof thousands of times over many hours and not once.

Practically, that adds $15 to $40 the square metre over a standard non-cyclonic fixing on the roofing alone. On a 200 square metre roof that is $3,000 to $8,000 of difference for the same sheets in the same colour, which is why a quote from an operator who works in Brisbane looks cheap against a Townsville quote and should not be compared with it. The standards that govern all of this, including the metal roofing installation standard and the wind loads for housing standard, are published by Standards Australia.

The tie-down path is where replacements go wrong quietly. A roofing contractor replaces the covering and the battens and fixes everything correctly to the rafters, which is the limit of their scope. If the connection from the rafter to the top plate and from the wall frame to the slab was built to a 1970s standard and the house now needs to resist a higher load, the new roof is stronger than what is holding it down. That is a worse outcome than leaving it alone, because failure moves to a part of the structure nobody inspected.

Where a house is in a cyclonic area and has not been assessed, a tie-down assessment by a structural engineer at $900 to $2,800 is money spent before the roofing quote instead of after. It produces a document saying what the load path is and what has to be done to it, and that document turns a vague risk into a priced item. The carpentry work to improve tie-down, where it is needed, is covered on our carpentry services page.

One consequence of all this runs against intuition and deserves stating. Taking the weight off a roof makes uplift matter more, not less. A concrete tile roof weighs forty-five to fifty-five kilograms the square metre and that mass helps resist suction. Metal sheeting weighs four to six kilograms over the same area. Converting from tiles to metal removes roughly nine tenths of the roof dead load, so the tie-down connections that were adequate under a heavy roof may not be adequate under a light one, and that is the subject of the next section.

Older housing stock is where the whole problem concentrates. Queensland houses built before the wind loading provisions were tightened following the 1974 Darwin event and subsequent code revisions were not designed for the loads now required, and a great many of them are still standing in cyclonic areas having never been tested by a severe event. A replacement is the one opportunity to improve that, because the roof is open and the connections are visible, and doing it later costs several times as much.

Converting a Tile Roof to Metal

This is the most common roof replacement decision in Queensland and usually the right one, for reasons that have little to do with how the roof looks. The conversion costs $110 to $190 the square metre against $90 to $160 for like-for-like tiles, so there is a premium, and understanding what that premium buys is the whole question.

What changes physically in a conversion is a good deal more than the covering. Tile battens sit at a spacing set by the tile gauge, typically around 320 millimetres for a standard concrete profile, and they are sized to carry a heavy load in bending between rafters. Metal sheeting needs battens at a spacing determined by the profile and the wind class, which is a different number, and the fixings go into the batten in a pattern that the old timber may not accept. New battens at $25 to $55 the square metre are part of the conversion itself and not an upgrade to it. A conversion quote without a batten line has either missed it or hidden it. Either way it is the first thing to query.

Sarking becomes necessary where it often was not before. A tiled roof is a ventilated assembly with gaps between every tile, so moisture that gets into the roof space finds its way out. A metal roof is a continuous impermeable sheet, and the underside of that sheet gets cold at night and collects condensation. Without a sarking membrane or an insulation blanket at $12 to $30 the square metre, that condensation drips onto the ceiling insulation and corrodes the sheet from underneath.

The change in weight is the structural headline of a conversion. Concrete tiles are forty-five to fifty-five kilograms the square metre and terracotta slightly less, while metal is four to six. On a 200 square metre roof that is nine to ten tonnes of dead load removed from the structure. That sounds purely beneficial and for gravity loading it is, but the same mass was contributing to uplift resistance, and the tie-down path now has to do that work on its own. In a cyclonic area that shifts the question from the roofer to an engineer. It is a different scope and a different fee, and it belongs before the roofing quote.

Pitch is the practical constraint most people forget about. Tiled roofs are generally laid at fifteen degrees and above, and almost any metal profile will work at that pitch. The problem runs the other way, where a low pitch roof cannot take certain metal profiles: corrugated profiles generally need around five degrees of fall, trapezoidal profiles such as Trimdek work down to about two or three degrees, and concealed-fix profiles such as Klip-Lok go lower again. A conversion on a steep tiled roof has no pitch problem at all.

Gutters and fascia almost always change with the conversion. A tiled roof terminates differently at the eave, the sheet overhang is different, and the existing gutter line was set for tiles. Doing fascia and gutter at the same time costs $75 to $160 the metre and costs far less than returning to it later, since the roof edge is already open and the access is already paid for. Our gutter replacement page covers the fascia and guttering side of it. Matching the new gutter profile to the new roof profile is part of getting the eave line right. A mismatched eave is the detail that makes a new roof look wrong from the street.

The benefits of a conversion are real and worth stating plainly. A metal roof sheds water faster and is far more tolerant of low pitch and of heavy intense rainfall, which matters across this state. It has no pointing to fail and no capping to rebed, which removes the main maintenance cost of a tiled roof. It weighs a tenth as much, it can be walked on by a tradesperson without breaking, and a sarked metal roof with an insulation blanket performs better thermally than an unsarked tile roof. That last point surprises people who assume mass alone governs comfort. What governs it is the insulation and the radiant barrier above the ceiling, not the weight of the covering.

The drawbacks are just as real and deserve the same treatment. Rain noise on a metal roof is louder, and while sarking and insulation reduce it a great deal, it does not vanish. Thermal movement means a metal roof clicks and ticks as it heats and cools, which some people never notice and others find intolerable. And in a Brisbane character area a metal roof on a house that was built with tiles can be the wrong aesthetic answer, though many pre-war Queensland houses had metal originally and converting back is a restoration, not a departure. Any house inside a character overlay needs that question settled with the council before anything is ordered. The overlay governs the look from the street, not the performance of the roof.

Insulation is the item to deal with while the roof is off, because it is never this easy again. With the covering removed the ceiling is accessible from above across the whole plan, and laying or replacing batts at $18 to $40 the square metre takes a fraction of the time it does through a manhole. Combining that with the re-roof is the single best value decision available on this job, and our ceiling and wall insulation page covers the scope.

Approvals, Licensing and the Paperwork That Matters

A roof replacement in Queensland sits in an awkward place in the approvals system, because the answer depends on what is changing instead of how much it costs. Replacing a roof covering like-for-like is generally treated as maintenance and needs no building approval. Changing the material, the profile, the pitch, the roof form or anything structural is building work and ordinarily needs a development approval or at least a building approval through a private certifier.

That distinction is what catches a tile-to-metal conversion in the approvals net. Changing from tiles to sheet metal alters the dead load on the structure and the batten and fixing arrangement, and in most councils that is enough to make it assessable work. A building certifier's approval and inspections run $900 to $2,500, and the structural design and inspection certificates that go with it are $600 to $1,800. Operators who tell you no approval is needed for a conversion are sometimes right and frequently are not.

Character and heritage controls are the second trigger and they are significant in Brisbane. The traditional building character overlay applies to houses built before 1947 across large parts of the inner and middle ring suburbs, and it regulates changes to the roof form and material where they are visible from the street. Replacing a corrugated metal roof on a pre-war Queenslander with the same thing is straightforward. Changing its form, its pitch or its material, or doing anything to a house with a heritage listing, needs consent. Guidance on the state planning framework and the approval pathways is available through the Queensland Government.

Licensing is the one part of this nobody should compromise on. Roofing work above the licensing threshold has to be carried out by an appropriately licensed contractor, and for work valued above $3,300 including materials that contractor must hold a licence and work to a written contract in the prescribed form. A roof replacement is always well above that figure. Licence class, currency and any history can be checked on the register maintained by the Queensland Building and Construction Commission.

The home warranty insurance point repays understanding, because it protects the largest sum of money most people spend on their house in a decade. Residential construction work above the insurable threshold attracts a premium under the statutory home warranty scheme, and that premium must be paid before the work starts. The cover responds if the contractor fails to complete the work or if defective work is not rectified. If the contractor has not paid the premium, the cover does not exist, and the only way to know is to ask for the notification. It arrives as a document with a policy number on it and not a verbal assurance. Asking for it is routine and no reputable contractor is offended by the request.

Roof plumbing is a separate licence class from general roofing and the distinction matters on this job. Gutters, downpipes, flashings connected to the stormwater system and the drainage side of the roof are plumbing work. The sheeting and the structure it sits on are not plumbing work. A contractor replacing a roof and its guttering needs both competencies covered, whether in one business or through a subcontractor, and our roof and gutter plumbing page covers that trade. Asking who is doing the drainage work is a fair question on any re-roof quote. Split responsibility at the gutter line is where disputes about leaks begin.

Safety is a legal obligation on the contractor and far less on the homeowner, but it shapes the price and it shows up when comparing quotes. Working on a roof is work at height, and the duties around fall prevention, edge protection and safe access are set out by WorkSafe Queensland. Scaffold and edge protection at $1,500 to $6,000 appears on a compliant quote and is absent from a non-compliant one, which is a large part of why some quotes look cheaper.

Keep four documents at the end of the job. The written contract, the home warranty insurance notification, the building approval and inspection certificates where the work needed them, and the manufacturer's warranty for the roofing material with the installer's details on it. That bundle is what answers a question from an insurer after a storm, from a buyer's building inspector at sale, or from a certifier years later when somebody does further work.

The Two Items That Blow Up a Roof Budget

Almost every roof replacement that goes badly over budget does so for one of two reasons, and both are visible before anybody signs anything. The first of those is asbestos cement sheeting and the second is a solar array. Neither is a disaster and both have known costs, but a quote that does not mention them when they are present is a quote that will be revised.

Asbestos cement roof sheeting was used widely in Queensland from the 1940s through to the late 1980s, mostly as corrugated sheeting on houses, sheds, garages, carports, patios and outbuildings. It is sometimes called super six or fibro sheeting. It looks like concrete-grey corrugated sheet, it is brittle instead of springy underfoot, and on an older house it is often found on an addition or a shed even where the main roof is tiles or metal.

Removal is $60 to $120 the square metre and that figure is not padding. Non-friable asbestos sheeting has to be removed without breaking it where possible, kept wet or sealed to suppress fibre release, wrapped and labelled, transported by an operator permitted to carry it and taken to a facility licensed to accept it. A householder may legally remove a small area of non-friable material at their own residence, but a roof is well past that threshold and needs a licensed removalist. The state information service covering identification, safe handling and removal requirements is at Asbestos Queensland.

A clearance certificate at $400 to $900 follows the removal and precedes the new roof. It is an independent confirmation that the area is clear and safe to reoccupy, and the document a future buyer's inspector will ask about. Our asbestos testing and inspection page covers identification before the job and asbestos removal covers the licensed work itself.

The trap with asbestos is sequencing more than cost. If it is identified during the strip-out and not before, the roofing crew stops, the removalist is booked at whatever notice they can give, the house sits with a partially stripped roof through a week of forecast storms, and temporary weatherproofing gets added to the bill. Identifying it first turns a crisis into a line item. Any sheeting of unknown type on a house built before 1990 should be tested, and a sample test is inexpensive. A few hundred dollars at that stage prevents a stoppage costing several thousand. It also tells you whether the shed and the patio need to be in the same scope.

Solar is the second item and now sits on a very large share of Queensland roofs. The array has to come off before the roof can be replaced and go back on afterwards, and that is $1,200 to $3,500 for a typical residential system. The work has to be done by a licensed electrician, and keeping the system's compliance and warranty position intact generally means using an accredited installer in place of a general trade, since the mounting, earthing and connection all have to be reinstated correctly.

Three separate complications sit inside that figure and any of them can move it. Mounting hardware is often not reusable, because rails and feet designed for the old roof profile may not suit the new one, and penetrations have to land on battens in the new layout. Older panels are sometimes no longer available, so a panel damaged during removal cannot be matched and the string has to be reconfigured. And where the system is more than a decade old, the honest question is whether reinstating it is better value than replacing it while the roof is open.

The network connection side needs checking early instead of at the end. Altering or reinstating a grid-connected system involves the electricity distributor, which across most of the south east is Energex and through regional Queensland is Ergon Energy, and the paperwork for that sits with the electrician and not the roofer. Connection requirements are published by Energex, and the administration of the small-scale renewable scheme sits with the Clean Energy Regulator. Getting the electrician to confirm the position before the panels come down avoids a system that is physically reinstalled but not formally reconnected. That gap is more common than it should be and it only surfaces at the next bill. Confirming the paperwork path at quote stage closes it.

Where the array is old enough that reinstatement is questionable, the decision should be made deliberately instead of by default. A ten year old system on a new thirty year roof is a mismatch, and the cost of taking it off and putting it back is a meaningful fraction of a new one. Our solar panel repairs page covers servicing an existing system and solar panel installation covers replacing it while the access is already paid for.

Two smaller items belong in the same category because they follow the same pattern. Skylights have to come out and go back in with new flashing kits at $800 to $2,500 each, and an old skylight is usually better replaced than reinstated. Roof ventilators and whirlybirds are cheap to add while the roof is open at $350 to $650 each and awkward to retrofit later, which is covered on our roof ventilation and whirlybird installation page.

Material Choice, Coastal Corrosion and Condensation

Material selection on a Queensland roof is mostly a corrosion question, and the variable that matters is distance from breaking surf. Standard pre-painted steel in a Colorbond or equivalent finish over an aluminium-zinc coated base performs well across inland and suburban Queensland for decades. Within a few hundred metres of the open coast, in the salt spray zone, it does not, and the manufacturers publish separate severe-environment products for exactly that reason.

The main profiles come from a small number of Australian manufacturers and the names recur on every quote. Lysaght supplies Custom Orb corrugated, Trimdek and the concealed-fix Klip-Lok range. Stramit and Fielders supply comparable corrugated, trapezoidal and standing seam profiles. The painted steel itself comes from BlueScope as Colorbond, with Zincalume as the unpainted aluminium-zinc coated option, and Colorbond Ultra is the specification intended for severe marine and industrial environments. Using the standard product inside the salt spray zone is the most expensive saving available on this job. The failure shows up as rust streaking from the fasteners within a few years.

Profile choice follows pitch and appearance more than performance. Corrugated is the traditional Queensland look and suits anything from fifteen degrees up comfortably. Trapezoidal profiles have deeper ribs, span further between battens and tolerate lower pitch. Concealed-fix profiles have no exposed fasteners through the sheet, which removes the most common leak path on a metal roof entirely, and they handle very low pitch, but they cost more and are less forgiving of foot traffic.

Fasteners are where coastal roofs fail first and where the cheapest saving is made. A Class 3 coated screw is perfectly adequate on an inland roof. A coastal roof needs Class 4 or stainless, and putting a lesser screw into a severe-environment sheet produces rust streaks down a roof that is otherwise fine within a few years. Buildex and comparable fastener ranges are specified by class for this reason, and asking which class is being used is a reasonable question on any coastal quote. The wrong class also voids the sheet manufacturer's warranty, which is the part people discover late. By then the roof is eight years old and the conversation is over.

Galvanic corrosion is the companion problem and it catches people who mix materials without thinking about it. Copper and lead in contact with or draining onto aluminium-zinc coated steel will corrode it, which is why an old lead flashing reused on a new metal roof is a poor decision. Unpainted Zincalume and Colorbond are compatible with each other and with zinc-coated fasteners, and that is about the extent of the safe combinations.

Tiles remain a legitimate choice and in some settings a better one. Concrete tiles from Monier or Bristile and terracotta from the same suppliers are entirely unaffected by salt, which makes them a sensible specification in a beachfront location where metal needs its most expensive grade. They are heavier, and that mass helps resist wind uplift. They are also considerably quieter than sheet metal in heavy rain. Their weakness is the pointing and bedding on the ridges, which needs attention every fifteen to twenty years, and their intolerance of foot traffic.

Condensation is the under-appreciated issue in this state and the national construction code now addresses it directly. A metal roof over an insulated ceiling creates a cold surface above a warm moist roof space, and in a humid climate that produces liquid water on the underside of the sheet. The provisions that deal with vapour permeability and roof space ventilation are in the code published by the Australian Building Codes Board, and they are the reason sarking specification is not a matter of preference.

In practice that means a vapour-permeable sarking membrane, or an insulation blanket with a foil facing where the specification calls for it, laid over the battens before the sheets go on. Thermakraft and Bradford both supply products for this and the choice depends on the climate zone and whether the roof space is ventilated. Combining the membrane with roof space ventilation is what actually solves the problem, because a membrane alone moves the condensation without removing the moisture.

Colour has a measurable effect on the roof space and on the house below it. A dark roof in Queensland runs considerably hotter than a light one, and in a house with modest ceiling insulation that difference is felt in the living spaces every summer afternoon. Light colours reduce the radiant load, and the solar absorptance figures manufacturers publish for each colour are a real number, not marketing. On a re-roof, where the colour is being chosen from scratch, it is a free decision with a lasting effect.

Two items are worth specifying while the choice is open. Leaf guard over the new gutters at $90 to $220 the metre is cheaper to install with the roof edge open and prevents the blockage that causes most gutter overflow, which is covered on our gutter guard installation page. And where the house has skylights or will get them, doing the openings during the re-roof is far cleaner than cutting them later, as set out on our skylight installation and repairs page.

Roof Replacement Costs Across Queensland

The regional spread on this job is wider than on almost any other household repair in the state, and the reason is wind classification more than labour rates. A house in the cyclonic region needs a different fixing specification, heavier battens, fatigue-tested sheeting and in many cases a tie-down upgrade, and none of that is optional. The table below gives indicative totals for a 200 square metre single storey roof and names the governing local factor in each region.

The pattern in that table is the cyclone line and not a gradual drift north. Prices across the south east, the Downs and the inland south sit in a fairly narrow band. From Bundaberg and Gladstone northward the figures step up and stay up, because the fixing specification changes and not because the labour costs more. Comparing a Cairns quote with a Brisbane one on price alone is comparing two different specifications.

Access and terrain do the rest of the work. Steep blocks through the Gold Coast and Sunshine Coast hinterlands, Toowoomba's range suburbs and the Townsville foothills add scaffold and crane or hoist time. Two storey and three storey houses add it again. A single storey house on a flat suburban block with a driveway alongside it sits at the bottom of every band in the state. Everything that makes a roof harder to stand on makes it dearer to replace. Pitch, height and the ground around the house do most of that work.

Timing matters more in Queensland than in most other states. Roofing demand across Queensland spikes immediately after any severe weather event, and in the weeks following a hailstorm or a cyclone crossing the coast there is no capacity and no discounting anywhere in the affected region. The sensible window for planned work is the dry season from about May to September, which is also when the weather risk of having a roof open is lowest. If the roof has already failed, our emergency roof repairs page covers making it safe while a replacement is organised. A temporary make-safe buys the time to get three proper quotes. Deciding a twenty thousand dollar job under water pressure is how people end up with the wrong roof.

One warning is specific to this state and bears repeating. After a significant hail or storm event, operators arrive from interstate and work through affected suburbs offering immediate replacements. Some of them are legitimate businesses holding local licences. Others are not licensed in Queensland, do not hold the insurance the statutory scheme requires, and will not be reachable in two years when a flashing leaks. Checking the licence number on the state register before signing takes two minutes and is the single most valuable thing anybody can do in that situation.

What to Look Out For in a Roof Replacement Quote

A roof replacement quote is one page of paper standing in for twenty thousand dollars of work, and the difference between a good one and a poor one is entirely in what it specifies. The useful habit is to read it as a specification and not as a price, because every meaningful variation on this job comes from something the quote did not say.

Start the comparison with the roof area, because everything else is priced against it. The quote should state the roof area in square metres and that figure should match the roof, not the floor plan. A hipped roof at twenty-two degrees with eaves is fifteen to twenty per cent larger than the floor area it covers, and a quote using the smaller number will either be revised upward or will run short of material. Ask how the area was measured and whether anybody has been on the roof or only looked at it from the ground. A quote produced from the footpath is an estimate wearing a quote's clothing. Drone photographs are a legitimate alternative to climbing up, and plenty of contractors now use them.

Then look at how the quote handles the site wind classification. Any quote in Queensland should name the site wind class it has been priced to, and in cyclonic regions that is not negotiable. A quote that does not mention wind class in Townsville or Cairns has been priced on an assumption, and if the assumption is wrong the fixing specification is wrong. Ask for the class and ask what screw pattern and washer type goes with it.

Battens need a line of their own on the page. The quote should say whether existing battens are being retained, and if so, on what basis somebody has concluded they are adequate for the new profile and the wind class. Retaining battens is legitimate and saves real money when they are sound. Retaining them because nobody checked is how a new roof ends up fixed to timber that cannot hold it. The failure, when it comes, looks like a roofing failure and is not one. That distinction matters a great deal when a warranty claim is being argued.

Sarking should be specified by product and not by the word. A quote saying sarking included is weaker than one naming a vapour-permeable membrane or a foil-faced insulation blanket with a stated thickness. This is the item most often dropped to win a price, and its absence is invisible from the ground and consequential in a humid climate. The same applies to insulation, which should be specified by R-value if it is included at all.

The edge details are where leaks come from and where quotes diverge. Fascia, gutter, valley irons, wall and parapet flashings, and the treatment where the roof meets a chimney, a neighbouring wall or a lower roof should each appear. A quote covering only the sheeting leaves every junction to be negotiated later, and the junctions are exactly where water gets in.

Check the licence and the insurance before the price. Roofing work above the threshold requires a licensed contractor and a written contract in the prescribed form, and the licence can be verified on the register held by the Queensland Building and Construction Commission. Ask for the home warranty insurance notification instead of an assurance that it is covered, because the cover only exists if the premium was actually paid.

Access and safety should be itemised and not absorbed. Scaffold and edge protection on a residential re-roof is $1,500 to $6,000 and a quote without it either intends to work unsafely or will add it later. The obligations around working at height are set out by WorkSafe Queensland, and a contractor who treats edge protection as an optional extra is signalling how the rest of the job will be run.

Ask what happens to the house if it rains mid-job. A roof replacement involves the house being open to the weather in stages, and in Queensland the question of how the roof is made weathertight at the end of each day is a real one. A contractor who has an answer involving staged sections and temporary covering has done this before. One who says it will be fine has not thought about it. A week of open roof through a storm season is where the ceiling damage comes from. Staged sections, with each one closed before the next opens, is the answer worth hearing.

On warranties, there are two and they are not the same. The material carries a manufacturer's warranty, typically a long one on the painted finish and the base metal, conditional on correct installation and on the right fastener class for the environment. The installer warrants their own workmanship, which is the fixing, the flashing and the weathertightness. Get both in writing and check the conditions on the material warranty, because a coastal roof with the wrong screws voids it. Warranty conditions on painted steel also specify washing intervals in marine environments. Almost nobody reads that clause and it is enforceable.

Compare three quotes on scope and expect them to differ. Where one sits thousands below the others, the gap is almost always sarking, battens, flashings, scaffold or disposal, not a better rate on the same work. The statutory consumer guarantees described by the Australian Competition and Consumer Commission apply to the work regardless of what the paperwork says, and they cannot be signed away by a clause in a quote. Keeping the contract and the invoices is what makes those guarantees straightforward to rely on later.

If a dispute does arise, there is a defined path and knowing it beforehand helps. Complaints about a licensed contractor run through the Commission first, with distinct timeframes for structural and non-structural defects, and matters that cannot be resolved there can proceed to the Queensland Civil and Administrative Tribunal. Dated photographs taken through the works are the most useful evidence anybody can hold. Our roof repairs page covers the cheaper alternative where a replacement is not yet warranted. Spending two thousand to buy another five years is sometimes the better financial decision. The right answer depends on how long you intend to own the house.

Getting Roof Replacement Quotes Across Queensland

Five pieces of information make a roof replacement quote accurate and all five can be gathered without going on the roof. The approximate roof area, taken from the floor plan with fifteen to twenty per cent added for pitch and eaves. The current material, whether concrete tile, terracotta, metal sheeting or cement sheet. The number of storeys and what the access is like on each side. Whether there is a solar array, how many panels and roughly how old. And whether any part of the roof, including sheds and patios, might be asbestos cement.

Photographs do considerably more for a quote than any written description. Each elevation from the ground, the roof from an upstairs window or a neighbour's vantage point if one exists, any visible damage, the gutter line, and the inside of the roof space through the manhole with a torch. The roof space photograph is the most useful of all, because it shows the battens, the rafters, whether there is any sarking and what condition the timber is in.

Say upfront if the house is pre-1947 and in an inner Brisbane suburb, or if it has any heritage listing, because the character overlay changes what is permitted and therefore what can be quoted. Say if the house is north of Bundaberg or within the coastal strip, because the wind classification changes the specification. Both of those are matters a local contractor will raise unprompted, and an operator who does not raise them is probably not local.

Decide before quoting whether the roof space work is in scope. Insulation, ventilation, skylights, new gutters with leaf guard and any wiring that runs through the roof are all far cheaper while the covering is off, and adding them afterwards means paying for access twice. Where this forms part of a larger project, the renovation services pricing covers the trades working alongside it, and on a pre-war house the Queenslander home painting page covers the exterior work that often goes with a re-roof.

Keep every document the job produces in one place, because a roof is the part of a house that gets questioned most often. The contract, the insurance notification, the approval and inspection certificates, the material warranty with the colour and profile recorded, the installer's workmanship warranty, and the asbestos clearance certificate if there was one. Set out the roof material, the area, the storey count and the suburb, and The Quote Yard will connect you with licensed Queensland roofing contractors who work in your region and quote to your wind class.
