Piyo ๐Ÿฃ: Poppo, I'm a surveyor and I want to use drones to inspect roofs on residential properties. What are the CASA rules and insurance requirements?

Roof Inspection Market in Australia

Industry Overview

Drone roof inspection is booming across Australia:

  • Annual market: A$100M+
  • Growth rate: 50% year-over-year
  • Key sectors: Residential, commercial, insurance, real estate

Why Drones Transform Roof Inspection

Traditional method (2015):
  • Roofer climbs on roof (dangerous)
  • Falls from height = most common workplace injury
  • Limited angles/views
  • Time-consuming (2โ€“4 hours per house)
  • Cost: A$500โ€“A$1,500

Drone method (2026):
  • No climbing (zero fall risk)
  • 360-degree coverage from ground
  • 4K video + thermal imaging
  • 30โ€“45 minutes per house
  • Cost: A$150โ€“A$400
  • CASA Regulatory Framework

    Standard CASR Part 101 Requirements

    Roof inspection (like all commercial operations) requires:

    1. Remote Pilot License (RePL) โ€” mandatory
    2. Remote Operator Certificate (ReOC) โ€” for professional services
    3. Flight plan โ€” submitted to ATC if controlled airspace
    4. Insurance โ€” A$20M public liability minimum
    5. VLOS compliance โ€” visual line of sight maintained

      • Tree canopy analysis (near roofs)

      Pre-Inspection Planning

      Client Intake Checklist

      Before scheduling:

        Safe Flight Procedure

        Recommended Flight Pattern:
        1. Approach from upwind

        • Takeoff from secure area
        • Climb to 50 feet altitude
        • Move upwind of property

        1. Orbital pattern around roof

        • Maintain 15โ€“20 meters horizontal distance
        • Circle entire perimeter clockwise
        • Vary altitude to capture all roof sections
        • Document chimney, vents, edges

        1. Close-up detail passes

        • Zoom in on problem areas (leaks, damage)
        • Capture 4K video of suspicious regions
        • Thermal imaging of any wet areas
        • Document flashing, gutters, valleys

        1. Landing approach

        • Return to takeoff zone
        • Reduce altitude gradually
        • Land in clear area (away from power lines)
        • Secure aircraft immediately

        Documentation & Reporting

        During Flight (Critical)

        • Capture all roof sections (360ยฐ coverage)
        • Zoom in on visible damage
        • Record 4K video for review
        • Document GPS coordinates and timestamps
        • Photograph problem areas from multiple angles
        • Note weather conditions

        Post-Flight Report Generation

        Standard report includes:
        1. Executive Summary

        • Insurance/warranty limitations

        Report Delivery Format

        Client delivery options:
        • PDF report with photos
        • Online portal (video clips + photos)
        • Annotated video walkthrough
        • Raw footage (if requested)
        • Insurance for Roof Inspection Business

          Mandatory Coverage

          Coverage Amount Cost
          Public liability A$20M A$4,000โ€“A$8,000
          Professional indemnity A$5M A$2,000โ€“A$5,000
          Equipment coverage Full replacement A$1,000โ€“A$3,000
          Total Annual โ€” A$7,000โ€“A$16,000

          Why Professional Indemnity is Critical

          Scenario: You inspect roof, report "minor damage," homeowner doesn't repair, roof leaks severely โ†’ causes A$50,000 water damage. Without E&O insurance:
          • Personal liability (potentially bankruptcy)

          With E&O insurance:
          • Insurance covers defense + settlement
          • Typical cost: A$3,000โ€“A$5,000/year, limits A$2โ€“A$5M
          • Pricing & Business Model

            Australian Market Pricing (2026)

            Property Type Inspection Cost Time
            Residential (single story) A$150โ€“A$250 20โ€“30 min
            Residential (two story) A$250โ€“A$400 30โ€“45 min
            Commercial building A$500โ€“A$2,000 1โ€“2 hours
            Insurance claim inspection A$300โ€“A$500 45 min
            Thermal + standard +A$100โ€“A$200 Add 15 min

            Revenue Model Example

            Assume 5 inspections per week:

            Item Amount
            Inspections/week 5
            Average price A$300
            Weekly revenue A$1,500
            Monthly revenue A$6,000
            Annual revenue A$72,000
            Less: Insurance (A$12,000) -A$12,000
            Less: Equipment maintenance -A$3,000
            Less: Vehicle/fuel -A$5,000
            Less: Software/tools -A$2,000
            Net profit A$50,000

            Common Mistakes to Avoid

            Procedural Errors

            • โŒ Flying without proper airspace check (might cross controlled airspace illegally)
            • โŒ Not maintaining VLOS (lose sight of drone)
            • โŒ Flying during strong wind (loss of control)
            • โŒ Poor landing (crash into property = liability)
            • โŒ No pre-flight safety assessment (collision risk)

            Professional Errors

            • โŒ Providing repair quotes (outside licensing scope)
            • โŒ Guaranteeing roof condition (liability exposure)
            • โŒ Not documenting findings adequately (claims disputes)
            • โŒ Sharing photos without permission (privacy violation)
            • โŒ Flying without ReOC (regulatory violation)

            Safety Errors

            • โŒ Flying near power lines (electrocution risk to drone + interference)
            • โŒ Operating in restricted airspace (military, airport zones)
            • โŒ Flying over people (even during routine inspection)
            • โŒ No battery reserve (forced landing on neighbor's property)
            • โŒ Ignoring weather changes (sudden wind gusts)
            • FAQ

              Q: Do I need a ReOC for roof inspection?

              A: Yes. Any commercial drone flying requires ReOC (unless drone under 250g with simple operation).

              Q: What if I fly over a neighbor's property to inspect a roof?

              A: You must maintain VLOS and have property owner permission. Flying over neighbor's property without permission = trespass + privacy violation.

              Q: Can I do roof inspections for property developers?

              A: Yes, absolutely. Excellent B2B market. Higher pricing (A$500โ€“A$2,000 per property).

              Q: Should I provide repair recommendations?

              A: Observations yes (e.g., "damaged flashing visible"); repair quotes NO (requires licensed roofer). State this clearly in report.

              Q: What if I discover asbestos roofing?

              A: Document it, note in report, recommend licensed asbestos specialist. Don't diagnose or advise removal (outside your scope).

              Q: How do I handle insurance claims inspections?

              A: Different rules apply. Insurance companies may have specific documentation requirements. Contact insurer before flying for claims work.

              Q: Can I charge extra for thermal imaging?

              A: Yes! Thermal adds significant value. Charge +A$100โ€“A$200 for thermal inspection. Market commands premium pricing.

              Q: What if client refuses to pay after inspection?

              A: Have written quote and contract signed before flying. Small claims court if necessary. Insurance provides dispute coverage.

              Q: Does MmowW help with roof inspection compliance?

              A: Yes. MmowW tracks ReOC compliance, flight logs, client documentation, and insurance status. Cost: A$8.50/drone/month.

              Q: How many roof inspections can one person do per day?

              Key Takeaways

              โœ… Roof inspection is lowest-risk drone business (no flying over people) โœ… ReOC required from CASA โœ… High profit margins: 60โ€“75% typical โœ… Professional indemnity insurance critical (liability exposure) โœ… Thermal imaging adds 30โ€“40% value to inspections โœ… Pricing: A$150โ€“A$400 residential, A$500โ€“A$2,000 commercial โœ… One person can generate A$70,000+ annual profit (5 inspections/week)
