About this ITP: ITP defining inspections for zinc roll-cap roofing: materials, substrate, membranes, clips, seams, junctions, soldering, expansion joints, and final handover.

More than a static template

Unlike a downloadable Word or PDF template, this ITP is an AI-assisted editable starting point directly connected to its method statement. Every inspection activity, hold point, and acceptance criterion is structured and ready to adapt to your project.

  • AI-assisted customization — Tailor inspection activities and acceptance criteria to your specific project scope.
  • Linked method statement — This ITP is connected to the corresponding method statement describing the work sequence.
  • Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
  • Editable starting point, not a final document — Review and verify all content against your project specifications and standards before use.

What you can customize

When you save this ITP to your account, every inspection row becomes editable. You can add, remove, or modify:

  • Inspection activity — Description of what is being inspected.
  • Inspection type — Hold point (H), Witness point (W), Review (R), or Monitor (M).
  • Responsibility — Contractor, subcontractor, engineer, or client.
  • Frequency — How often the inspection occurs.
  • Acceptance criteria — Referenced standard or specification requirement.
  • Records — Forms, test reports, or checklists required as evidence.

Why this ITP is used

To verify each critical stage of zinc roll-cap roofing meets design, standards, and manufacturer requirements.

Who uses this inspection and test plan

Specialist roofing subcontractor, main contractor QA/QC, and the Engineer’s Representative.

When this ITP is prepared and submitted

From material delivery through installation and final handover, with hold and witness points at concealed and critical stages.

Who receives or approves this ITP

Engineer/Consultant for review and approval.

Inspection scope

Covers materials certification, substrate readiness, membranes, separation layer, battens, panel fabrication, clip layout, seams, junctions, soldering, expansion joints, and final inspection.

Typical hold, witness, and review points

Hold: substrate acceptance, battens first area, clip layout, first-of-kind bay, expansion joints, final handover. Witness: membranes, separation, tray fabrication, soldering, junctions.

Typical inspection records

Material certs, moisture logs, checklists for membranes and separation layers, clip schedules, seam height records, hot work logs, photos, as-builts, warranties.

Important approval note

This ITP is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all inspection activities, hold points, and acceptance criteria must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

Always verify acceptance criteria against your applicable drawings, specifications, and regulatory requirements. Hold points must be confirmed with the relevant authority before work proceeds past that point.

Inspection and test plan

Activity Inspection / Test Acceptance Criteria Responsibility Record
Material delivery and certification Verify EN 988/ASTM B69 certificates, batch numbers, finishes Certificates match delivery; finishes per submittal; no transport damage Subcontractor / Engineer (Review) Material inspection report & certs
Substrate readiness Moisture content measurement; flatness survey; fastener pull-out test if required Moisture ≤18%; flatness ±3 mm over 2 m; pull-out ≥ design value [Verify] GC / Subcontractor / Engineer Substrate acceptance form
Underlay membrane installation Check laps, terminations, taped seams, vent path continuity Laps ≥100/150 mm; taped per manufacturer; full continuity; no tears Subcontractor / Engineer (Witness) Membrane checklist & photos
Structured separation layer Coverage and no compression bridges 100% coverage; maintains ventilation void; neat terminations Subcontractor / Engineer (Witness) Separation layer checklist
Batten/roll installation Spacing, line/level, fixing type/spacing Spacing ±5 mm; straightness ±3 mm over 3 m; fixings per design Subcontractor / Engineer (Hold for first area) Batten installation record
Tray and cap fabrication Dimensional checks, edge quality, finish protection Width ±3 mm; length ±5 mm; clean, burr-free edges Subcontractor / Engineer (Witness) Fabrication log
Clip type and spacing Verify fixed vs sliding clip zones; spacing vs wind calc Clip layout per approved schedule; fixings stainless; sliding movement free Subcontractor / Engineer (Hold) Clip schedule sign-off
First-of-kind bay installation Seam height, straightness, visual quality Cap height 40–60 mm ±5 mm; lines true; no visible gaps Subcontractor / Engineer (Hold) Mock-up approval
Junction details (eaves, ridge, abutments, valleys) Measure upstands, laps, ventilation continuity Upstands ≥150 mm; laps ≥100–150 mm; ridge vent continuity Subcontractor / Engineer (Witness) Junction inspection sheets
Soldered joints (if specified) Visual continuity; flux removal Continuous fillet; no pinholes/voids; surfaces neutralized/clean Subcontractor / Engineer (Witness) Hot work log & photos
Expansion joint installation Dimension vs calculated ΔL; movement check Capacity ≥ required ΔL with contingency [Verify] Subcontractor / Engineer (Hold) Expansion joint record
Final inspection and documentation Close-out of punch items; optional localized hose test at details All ITP points passed; documents submitted; no leaks or visible defects Subcontractor / Engineer (Hold) ITP close-out, as-builts, warranties
