What this calculator estimates

This calculator quotes the all-in installed price for a residential roof inspection in 2026 Australian dollars. It separates the bill into the line items real ARC-member licensed roof plumbers invoice:

  • Inspection fee — base walk-over fee scaled by roof size, pitch, material, storey count, and inspection type.
  • Written condition report — PDF report with photos and findings.
  • Insurance-grade documentation — claim-ready format with AS 1562 / AS 2050 reference for adjusters at NRMA, Allianz, Suncorp, RACQ, AAMI.
  • Drone aerial scan add-on — CASA-licensed pilot operation.
  • Thermal scan add-on — pre-dawn or post-sunset IR sweep for heat-loss and trapped moisture.
  • Moisture probe survey — dielectric resistance probing to quantify trapped water.
  • Priority same-week service — 25 percent surcharge for fast-turnaround.

A minimum call-out fee of A$295 applies in most Australian metros and rises to A$350 in inner Sydney and Melbourne — small inspections hit the floor because mobilising a roof plumber, vehicle, ladders, and report time is the dominant cost on small jobs.

How to use it

  1. Pick roof size — small (under 140 m²), medium (140–230 m² default), large (230–370 m²), or very large (over 370 m²). Ground-projected plan area.
  2. Pick inspection type — visual walk-over (standard), drone aerial, thermal IR, moisture probe, or comprehensive bundle.
  3. Set roof pitch — low (under 18 degrees), moderate (18–37 degrees default), or steep (over 37 degrees, harness access).
  4. Pick roof material — concrete or terracotta tile, Colorbond/Zincalume, other metal sheeting, flat membrane / box-gutter system, or slate.
  5. Set storey count — 1.0 single, 1.1 two, 1.3 three or higher.
  6. Toggle written report if you want a PDF deliverable (default ON).
  7. Toggle insurance-grade if filing a claim or supporting a property sale.
  8. Toggle add-on scans if you chose a visual base but also want drone, thermal, or moisture.
  9. Toggle priority for fast turnaround.

Add 10 percent for two-storey access, 30 percent for three-storey (common in inner-city terraces and Sydney harbour-side homes), and 30 percent for steep roofs above 37 degrees.

Cost drivers

Inspection type. Visual walk-over is the cheapest and most common. Drone surveys cost about 35 percent more because of equipment cost, CASA-licensed pilot certification, and image processing. Thermal IR roughly doubles visual cost — the camera alone is A$5,000 to A$15,000 capital and inspectors work outside business hours for thermal contrast. Moisture probes cost 75 percent more than visual for grid-mapping time.

Roof size. A 130 m² project home with a simple gable takes 45 minutes to walk. A 370 m² double-storey with valleys, dormers, and a box-gutter takes two hours.

Pitch. Above 37 degrees, most roof plumbers require harness, rope, or roof ladders for WorkSafe / SafeWork compliance (each state has its own regs, all referencing WHS Regulation 2017 Part 4.4). Set-up adds 30 to 45 minutes and the inspection itself takes 50 percent longer.

Material. Slate roofs are most expensive to inspect (fragility, broken-tile risk). Concrete and terracotta tile add 10 percent (terracotta is especially fragile after 30+ years). Colorbond and Zincalume add 5 percent for seam-detail check. Flat membrane and box-gutter are fastest to walk.

Storey count. Two-storey adds 10 percent. Three-storey or higher adds 30 percent because of 10-metre extension ladders, stand-off stabilisers, and the time premium for working at height under WHS Regulation 2017.

Geography. Sydney and Melbourne CBD run 30 to 40 percent above national. Outer suburbs of Sydney, Melbourne, Brisbane, Perth, Adelaide are at or near national. Regional and remote add travel surcharge (A$1.00 to A$2.50 per km beyond 25 km). NT, FNQ, and remote WA can add 50 to 100 percent for travel and accommodation on larger jobs.

When to get a roof inspection

Pre-purchase. Every offer on a home with a roof over 15 years old in NSW, Vic, Qld, SA, and WA should include a roof-specific inspection contingency beyond the standard AS 4349.1 building inspection. A$390 to A$650 is the cheapest insurance in Australian property purchase.

Post-storm. After major hail events (SE Qld, Hunter NSW, ACT, Adelaide Hills), cyclones (FNQ, NT, north WA), or wind events (Vic, Tas, SA), get an ARC or MPA-member inspection within 30 days. Most policies have a 12-month claim window but documenting early matters.

Pre-sale. Sellers who pre-inspect their roof and produce a clean condition report close deals faster and avoid surprise buyer-side discoveries.

Routine. Every 3 to 5 years for Colorbond under 20 years old. Every 1 to 2 years for terracotta tile over 30 years old, or any roof under any material in coastal salt-spray zones (within 5 km of ocean). Annual for any box-gutter or parapet-wall system.

Before re-roofing. A full moisture survey before flat or box-gutter re-roofing tells you whether strip-and-re-board is needed or overlay is appropriate.

Insurance renewal. Some insurers (NRMA, Allianz, Suncorp, RACQ) request a recent condition report at policy renewal for homes with roofs over 20 years old, especially in known hail and cyclone zones.

What to expect from a professional Australian roof plumber

A competent ARC or MPA-member roof plumber will:

  1. Walk every accessible plane of the roof (or fly drone where walking is unsafe).
  2. Inspect every penetration: chimney, vent, skylight, plumbing stack, exhaust fan, box gutter.
  3. Photograph every elevation and every defect with reference to a roof plan.
  4. Probe ridge-tile bedding, hip-tile pointing, valley flashings, and barge cement.
  5. Inspect Colorbond and Zincalume for fastener back-out, edge corrosion, and seam separation.
  6. Inspect from the roof space: sarking, batten condition, ventilation balance, insulation condition, anticon foil integrity.
  7. Identify and date estimated remaining service life with photos.
  8. Deliver a written report with embedded photos within 48 to 72 hours.

Red flags: refusal to walk the roof, refusal to enter the roof space, no written report, no ARC/MPA membership or licensed roof plumber registration, and any “free inspection” tied to a sales pitch for replacement.

Australian codes and standards

  • WHS Regulation 2017 Part 4.4 — Working at height (state-by-state implementation).
  • CASA Part 101 — Drone pilot certification for commercial aerial inspections.
  • AS 1562.1 — Design and installation of sheet roof and wall cladding (metal).
  • AS 2050 — Installation of roof tiles.
  • AS/NZS 3500.3 — Plumbing and drainage — Stormwater drainage.
  • AS 4349.1 — Inspection of buildings — Pre-purchase inspections — Residential buildings.
  • NCC Volume 2 / Housing Provisions — Cyclone, wind, and bushfire-ember requirements.
  • ARC Industry Code of Practice — Roof plumbing inspection scope and detailing.

A contractor offering a “free inspection” who insists on starting work that day is the most common Australian roofing scam pattern — Consumer Affairs in every state has issued warnings, particularly after major hail or storm events. A legitimate roof plumber charges a fee, delivers a report, and has no ownership stake in any subsequent repair.

Diagnostic walk-through

  1. Kerb and binocular check — slipped tiles, lifted Colorbond seams, weathered flashings, dark moss bands.
  2. Eave and gutter check — sagging, leaf debris, joint leakage, hail dimples on the gutter face.
  3. Field walk — broken tiles, fastener back-out, lifted seams, hail dimples on Colorbond pans.
  4. Penetration check — chimney apron + step + counter flashing, skylight curb seals, vent collars, plumbing-stack lead-free flashings.
  5. Valley check — open-valley lap integrity, debris dam, hail-dimple zone.
  6. Ridge and barge check — mortar bedding, ridge-cap alignment, dry-fix vs wet-bed.
  7. Roof space check — sarking stains, batten rot, ventilation balance, insulation depth, anticon foil integrity.
  8. Box gutter check (if present) — fall direction, overflow provision, sole-plate condition.

Avoiding scams and overcharging

The free-inspection-then-replacement-sales-pitch is one of the most reported residential property scams in Australia, especially after hail events in SE Queensland and the ACT. Red flags:

  • Unsolicited door-knocker after a hail or storm event claiming “wind damage.”
  • Pressure to sign a contract on the first visit.
  • Refusal to provide a licensed roof plumber registration number or public-liability certificate.
  • Verbal-only findings, no written report.
  • Quotes that escalate from A$400 of “minor repair” to A$30,000 of full re-roof.
  • Demand for cash deposit over 25 percent.

Always pay for the inspection separately from any repair quote. Get a written report. Verify the roof plumber’s licence on the state regulator website (NSW Fair Trading, VBA in Vic, QBCC in Qld). If you suspect storm damage, contact your insurance before signing any contract.

Frequently asked questions

How much does a roof inspection cost in Australia in 2026?
Most Australian homeowners pay A$295 to A$650 for a standard visual roof inspection on a medium 180 m² single-storey home in 2026. Drone aerial scans run A$425 to A$850, thermal infrared inspections A$580 to A$1,250, moisture probe surveys A$525 to A$1,100, and full comprehensive inspections A$900 to A$1,950. Two-storey homes add 10 percent, three-storey add 30 percent. Steep roofs above 37 degrees add 30 percent for harness access. A minimum call-out fee of A$295 applies in most metros. Source: 2026 hipages, Service Seeking, and ARC contractor surveys plus Q1 2026 quotes from Sydney, Melbourne, Brisbane, Perth, and Adelaide.
Should I get a separate roof inspection beyond the pre-purchase building inspection?
Yes. A standard pre-purchase building inspection (AS 4349.1) examines the roof from external visual perspective and from inside the roof space — the inspector almost never walks the roof tiles or sheeting itself, and rarely identifies hail damage, lifted Colorbond seams, loose ridge capping mortar, or hidden flashing failure. For properties with roofs over 15 years old, terracotta tile homes, or homes in known hail belts (SE Queensland, Hunter NSW, ACT, Adelaide Hills), a separate inspection by an ARC-member roof plumber costs A$350 to A$650 and can save A$15,000 to A$40,000 in undisclosed repair costs.
What's the ARC and why does it matter?
The Australian Roofing Contractors Association (ARC) and Master Plumbers Australia (MPA) are the two industry bodies for roof plumbing. ARC and MPA members are vetted on insurance, licensing, and code-of-practice compliance. Their reports are widely accepted by insurers (NRMA, Allianz, Suncorp, RACQ, RACV) for claim documentation. State-by-state, all roof plumbing work must be performed by a licensed roof plumber under AS/NZS 3500.3 and AS 1562 — for any insurance-grade inspection demand a licensed roof plumber with ARC or MPA membership and current public-liability insurance of at least A$10M.
When should I get a thermal or moisture survey?
Thermal infrared surveys find heat-loss signatures and trapped moisture in box-gutter, parapet-wall, and flat membrane roofs that visual inspection cannot detect. Moisture probe surveys use dielectric resistance meters to measure water content in batt or panel insulation and decking. Use thermal when: the roof is over 15 years old, when you see ceiling stains without obvious source, after major hail or cyclone, or for any flat or low-slope commercial roof. Use moisture probes when: thermal scan shows wet zones, or before re-roofing a flat or box-gutter roof to know whether tear-off or overlay is appropriate. For a pre-purchase visual on a 5-year-old Colorbond roof you do not need either.
Does home insurance cover the cost of a roof inspection?
Home insurance typically does NOT pay for routine roof inspections — that is considered maintenance. However: if you have storm or hail damage and need a written roof plumber report to support a claim, most major insurers (NRMA, Allianz, Suncorp, RACQ, AAMI) will reimburse the inspection fee as part of the claim payout (up to A$500 to A$800). File the claim first, ask the insurer in writing whether inspection fees are covered, and keep the tax invoice. Some policies do reimburse; cheaper policies often do not.
How long does a roof inspection take?
A standard visual inspection of a 180 m² single-storey Colorbond or tile roof takes 45 minutes to 90 minutes on site, plus another hour for the written report. Drone surveys add 20 to 30 minutes for flight planning and capture (CASA-licensed pilot required for commercial work). Thermal infrared surveys must happen before sunrise or after sunset for thermal contrast — they add 60 to 120 minutes. Moisture probe surveys add 30 to 90 minutes. A comprehensive inspection on a medium home takes 3 to 5 hours on site. Two-storey, three-storey, and steep roofs can double the time.
Can I inspect my own roof?
You can do a binocular and roof-space check yourself: from the ground, look for slipped tiles, lifted Colorbond seams, missing ridge mortar pointing, weathered lead-free flashings, and dark moss bands. From the roof space, check sarking and battens for water staining around chimneys, vent pipes, and valley gutters. What you cannot replicate: walking the field to find storm-loosened tiles or fastener back-out, probing the integrity of step-flashings, or finding trapped moisture under torch-on or single-ply on commercial low-slope. The DIY path is fine for routine 6-month checks. For pre-purchase, post-storm, and insurance-grade documentation, hire an ARC or MPA-member licensed roof plumber.
What should be in a written Australian roof inspection report?
A professional report should include: photos of every elevation and every roof penetration (chimney, vent, skylight, box gutter, dormer); identification of the roof system (covering material profile, batten and purlin spec, sarking, manufacturer and approximate age); itemised list of defects with photos and locations; expected remaining service life with confidence range; recommended repairs prioritised by urgency (immediate, 0–12 months, 1–3 years, monitor); cost estimates per recommendation; insurance-relevant findings (hail, wind, cyclone, fire-ember) clearly flagged with reference to AS 1562 / AS 2050 / AS 3500.3 / NCC. Reports under 8 pages on a typical home are usually too thin — demand 12 to 25 pages with embedded photos for any inspection over A$350.
