The short answer
Roofing margins are decided before anyone climbs a ladder: how fast and accurately you can measure a roof from aerial imagery, turn that into a priced quote, and, for insurance repairs, prove the damage and the fix with photos. Australian roofers usually combine aerial imagery such as Nearmap, a job tool such as ServiceM8 or Tradify, and spreadsheets for pricing. The custom builds that pay are a measurement to quote tool using your own supplier pricing and an insurance job app for scopes and photo evidence, typically in the $20,000 to $70,000 (AUD, ex GST) market range.
Key takeaways
- Nearmap says it captures Australian imagery at 4 to 7.5 cm per pixel or better, up to six times a year in key areas, and offers APIs, which makes desktop roof measurement practical for most urban jobs.
- In NSW, roof tiling, roof slating and roof plumbing work valued at more than $5,000 in labour and materials (including GST) needs a contractor licence, with fines of up to $22,000 for individuals and $110,000 for companies for unlicensed work.
- Work at heights of more than 2 metres is high risk construction work, so a SWMS must be prepared before it starts, and it can be kept electronically.
- A generic SWMS reused across sites may not meet WHS requirements unless it is reviewed for each workplace, which is a good reason to build it into the job flow.
- Insurance repair work is won on turnaround and evidence, so photo capture and scope formatting deserve as much attention as quoting.
Why is roof quoting harder than most trades?
A roof quote depends on geometry you can’t see from the ground: area, pitch, number of faces, hips, valleys, ridges and penetrations, plus access and height. An electrician can count power points. A roofer needs a measured model of the roof before the materials list makes sense, and small measurement errors multiply across sheets, battens, flashings and labour.
That is why roofing is one of the few trades where estimating software, rather than job management, is often the first priority. Speed matters too. The roofer who sends an accurate quote the same day usually wins the job, and the one who books a measure and quote visit for next week often doesn’t.
How does aerial measurement work in Australia?
High resolution aerial imagery lets an estimator measure most urban roofs from a desk, then confirm on site before work starts. Nearmap is the best known Australian source. At the time of writing (November 2026) it describes imagery at 4 to 7.5 cm per pixel or better, captures of key areas up to six times a year, a historical archive, AI generated property layers including roof attributes, and integrations and APIs for delivering data into other systems. Pricing is by quote.
What aerial measurement does well:
- Plan area and outline of each roof face
- Pitch estimates where imagery and 3D data allow
- Ridge, hip and valley lengths
- Spotting solar panels, skylights, vents and trees overhanging the roof
- Before and after comparison from the archive, useful for storm claims
Where it struggles: roofs under heavy tree cover, recent work not yet in the imagery, very steep or complex roofs, and anything you can’t see from above, such as rusted fixings or cracked tiles. Treat aerial measurement as the quote basis and the site check as confirmation, and record which you relied on.
US products such as RoofSnap and EagleView are common in American roofing, but they are built around US imagery and workflows. Check their Australian coverage and fit before you sign up.
How should measurements become a quote?
The quote engine should turn measured quantities into materials and labour using your rules and your current supplier prices, without anyone retyping numbers. This is the step most roofers still do in a spreadsheet, and it is where a custom tool pays back fastest.
A worked example of the logic, using illustrative figures:
- Measured plan area: 180 m² across six faces.
- Pitch factor applied per face to get true surface area: for a 22.5 degree pitch, the factor is about 1.08, so roughly 195 m².
- Waste allowance by roof complexity, say 8% for a hip roof: about 210 m² of cladding.
- Linear items from the model: ridges, hips, valleys, barge and gutter lengths, converted to flashings and capping by your standard lengths and laps.
- Fixings, sarking, battens and safety mesh calculated per square metre by your rules.
- Current supplier prices applied from your latest price list, with your margin.
- Labour from your rates by roof type, height, pitch band and access.
- Options: a new roof in two profiles or colours, gutters on or off, whirlybirds as an add on.
Each step is simple. The value is in doing them consistently, from the measurement, in minutes, with the logic stored once. Metal roofing work is designed and installed to AS 1562.1:2018, which Standards Australia lists as current; your estimator decides how the standard’s requirements feed your rules.
The quote should then land in your job tool as line items, not a PDF attachment, so the accepted quote becomes the job and the purchase order without rekeying.
What WHS records does working at heights require?
Roofing is high risk construction work whenever there is a risk of a fall of more than 2 metres, so a safe work method statement must be prepared before the work starts. Safe Work Australia’s information sheet sets out the main points:
- A SWMS is required for the 18 high risk construction work activities in the WHS Regulations, which include work at heights of more than 2 metres.
- It must be prepared before the work starts, by or for the business carrying out the work, in consultation with the workers doing it.
- A generic SWMS used at different workplaces may not meet the requirements unless it is reviewed for the specific workplace and amended as needed.
- Work must stop if it isn’t being done in line with the SWMS, and the SWMS must be reviewed when controls change.
- It should be kept at the workplace, or where it can be delivered quickly, and it can be kept electronically.
Safe Work Australia also publishes a model Code of Practice on managing the risk of falls in housing construction. In software terms, the job record should carry a SWMS reviewed for that site, the edge protection or fall arrest plan, sign on by each worker, and photos of the controls in place. A checklist that blocks a job from starting until the site specific review is done is cheap to build and easy to defend.
How does insurance repair work change the software?
Insurance work is won on turnaround and lost on evidence, so it needs structured scopes and photo trails, not just quotes. Roofing repairs after storms commonly come through builders or assessors working for insurers, and each has its own scope format, photo requirements and approval steps. The roofer who supplies exactly what is asked, first time, gets paid sooner and gets the next job.
An insurance job app should handle:
- A scope of works broken into line items, each linked to its photos
- Photos taken in app with time and location kept, before, during and after
- Aerial imagery from before and after the event date where available
- Measurements and materials tied to the scope, not a separate quote
- Variations raised with evidence and approved before the work
- A report formatted the way each builder panel or insurer requires
AI can help at the edges: suggesting scope items from photos, or drafting the report from site notes for the estimator to check. Our insurance claims automation page covers the insurer side of the same process.
What licences apply to roofing work?
Licensing depends on the state and the category of roofing work. In NSW, roof tiling, roof slating and roof plumbing are separate categories. For each, the NSW Government says you need a contractor licence to carry out, advertise or contract for work valued at more than $5,000 in labour and materials, including GST, with fines under the Home Building Act 1989 of up to $22,000 for an individual and $110,000 for a company for unlicensed work.
Two software implications follow. Your quote tool should know the job value including materials and flag work that crosses the threshold for the category, and your scheduler should know which licence each worker holds. A business working across state lines needs those rules per state.
Typical builds and indicative costs
Roofers usually get the best return from one build at the front of the job. Figures are indicative AUD market ranges, ex GST, not quotes, within the bands Expeed publishes for Australian custom software: $15,000 to $40,000 for simple internal tools and $40,000 to $150,000 for mid complexity systems.
| Build | Includes | Indicative range |
|---|---|---|
| Measurement to quote tool with supplier pricing | Imagery or measurement import, pitch and waste rules, linear items, supplier price lists, labour bands, options, push to job tool | $30,000 to $70,000 |
| Insurance job photo and scope app | Scope line items, in app photos with metadata, before and after imagery, variations, report formats per panel | $20,000 to $50,000 |
Expeed puts annual maintenance at 15% to 20% of the build. Imagery API costs are separate and set by the provider. The main drivers are how many roof types and supplier lists you price, and how good your job tool’s API is. Our guide on comparing software quotes helps you read any proposal you get.
How AWLabs would approach a roofing build
We’d start with a Development Consult and ask to see how your best estimator prices a roof today, spreadsheet and all. If custom work makes sense, a paid Discovery Audit tests the imagery source, your supplier price files and your job tool’s API, and you get a fixed price Schedule of Work with three options: The Minimum, The Recommended and The Complete. Senior engineers lead every build, with updates every Tuesday and Friday, Sydney time.
AMS Roofing is a client and a named reference on our client stories page, for website work. We haven’t yet delivered estimating software for a roofer. See our AI integration and custom app development services, the trades software comparison, and our construction and trades work.
Frequently asked questions
What is the best roof estimating software in Australia?
There isn't one product that does everything for Australian roofers. Many use Nearmap or similar imagery to measure, a job tool such as ServiceM8 or Tradify to quote, schedule and invoice, and a spreadsheet for their pricing rules. US products such as RoofSnap and EagleView are built around US data and workflows, so check Australian coverage and fit before you commit.
Can I quote a roof without a site visit?
Often, for urban homes with clear imagery, you can quote within a tolerance and confirm on site before work starts. Steep pitches, complex roofs, trees over the roof, recent extensions and access problems still justify a visit. A good tool records the measurement source and date on the quote, so everyone knows what it was based on.
Do I need a licence for roofing work in NSW?
For roof tiling, roof slating and roof plumbing work, NSW requires a contractor licence to carry out, advertise or contract for work valued at more than $5,000 in labour and materials, including GST. Each category has its own licence types. Other states set their own thresholds, so check your state regulator.
Can software help with insurance roof repairs?
Yes. The useful pieces are a structured scope of works, photos taken against each scope item with time and location kept, and a report formatted the way your builder panel or insurer asks. That shortens the back and forth that delays approval and payment.
Have you worked with roofing businesses?
AMS Roofing is an AWLabs client and has agreed to be named as a reference; that work was a website, not job software. We haven't yet built estimating or job management software for a roofer, so we'd approach it with your estimators and your supplier pricing at the centre.
