Metal Roof Defect Reports:
Stop Guessing. Get Forensic Proof.
Comprehensive diagnostic investigation of Klip-Lok, Custom Orb, and standing seam metal roofing failures. We identify non-compliant laps, fastener degradation, flashing defects, and thermal stress points with 4K drone thermography and non-destructive testing.
Why Commercial & Strata Metal Roofs Fail
Metal roofs are designed to withstand extreme Australian UV and torrential downpours. Yet over 65% of premature leaks stem from poor workmanship, non-compliant installation, and contractor corner-cutting.
Capillary Draw & Lap Leaks
Incorrect side and end-lap clearances allow standing water to draw upward against gravity via capillary action, penetrating sub-roof insulation blankets without visible surface damage.
Fastener Failure & Over-Torque
Over-driven screws crush EPDM washers, creating inverted funnels for stormwater. Under-driven screws back out under thermal cycling, compromising entire roof diaphragm integrity.
Galvanic & Incompatible Metals
Runoff from copper piping, lead flashings, or unwashed inert catchments directly onto Colorbond or Zincalume causes aggressive chemical pitting and catastrophic premature corrosion.
Why Roofing Contractors Guess While We Prove
Roofing repairers make money selling full roof replacements or applying temporary silicone band-aids. We sell independent, definitive scientific evidence. We do not perform repair work—meaning our reports are 100% impartial and legally authoritative.
- We find the exact breach location, avoiding unnecessary $100k+ reroofs
- Direct statutory references hold original builders legally accountable
- Full Scope of Rectification puts you in total control of contractor pricing
Typical Roofer Quote
"The whole roof is leaking. Needs complete replacement with scaffolding: $185,000." (No diagnostic testing, no causation analysis).
Our Forensic Defect Report
"Leak isolated to 4 non-compliant apron flashing laps and 18 over-torqued ridge screws. Targeted rectification cost: $7,200 with 10-year integrity restored."
Forensic Diagnostic Methodology
We inspect multi-level commercial complexes and residential properties without dismantling flashings, cutting sheeting, or risking safety.
4K Drone Aerial Audits
CASA-licensed drone surveys inspecting steep pitch, box gutters, parapets, and concealed roof areas safely without dangerous edge access.
FLIR Thermal Thermography
Infrared thermal imaging captures the differential thermal mass of trapped moisture beneath metal deck profiles and saturated foil sarking.
Controlled Water Simulation
Calibrated, low-pressure progressive flood and spray rack testing in accordance with AWA / AS 4420 testing protocols to reproduce elusive leaks.
Micron & Coating Testing
Digital coating thickness and zinc-alloy loss meters to quantify metal degradation, chalking, and coastal micro-climate salt attack.
Strict Compliance With Australian Building Codes
A defect report is only as strong as its technical citations. When dealing with builders, insurance underwriters, or tribunal hearings, every finding must be backed by enforceable Australian Standards and the National Construction Code (NCC).
Strata & Legal Tribunal Ready
Are you a Strata Committee or Building Owner facing builder disputes under statutory warranty periods? Our reports comply directly with the Expert Witness Code of Conduct (Uniform Civil Procedure Rules).
What You Receive in Your Formal Report
A detailed, forensic PDF document ready to issue to builders, insurers, strata owners, or legal tribunals.
Defect Log & HD Photographic Mapping
Every defect is indexed, GPS-located on a roof layout schematic, and documented with macro photography, drone captures, and thermal overlays.
Root-Cause Causation Analysis
Clear technical explanation proving whether failures are due to installation error, design non-compliance, thermal fatigue, or poor maintenance.
Tender-Ready Scope of Rectification
A step-by-step engineering repair specification. Send it straight to licensed contractors for competitive, apples-to-apples repair quotations.
