Roof Truss Quantity & Installation Verification Checklist

Essential Checklist+

Complete these critical checks before approving the work or proceeding to the next construction stage.

✓13 Inspection Points
✓4 Verification Categories
✓Truss Design Inputs+
  • Building span and length confirmed from actual field measurements or plans, not assumed
  • Roof pitch entered matches the actual design intent, not a rough guess
  • Truss spacing matches the roof sheathing/decking span rating and the actual roof load for this project
  • Local building code edition, wind/seismic zone, and snow load confirmed before finalizing
✓Truss Engineering & Design+
  • Confirmed this calculator does NOT replace an engineered, stamped truss design — a real truss order/design was obtained separately
  • Truss placement diagram from the manufacturer matches the actual roof plan and this takeoff's count
  • Girder trusses (trusses that carry other trusses, e.g. at a valley or opening) identified and engineered separately
  • Damaged or incorrectly-cut trusses are never modified in the field without engineering approval
✓Bracing & Installation+
  • Temporary erection bracing planned and installed as each truss is set — before it's left unsupported
  • Permanent bracing (web member bracing, continuous lateral bracing) installed exactly per the truss designer's drawing
  • Truss-to-wall connectors (hurricane ties/truss anchors) rated for the site's actual wind/seismic uplift requirement
✓Installation & Code Compliance+
  • Permit and framing inspection requirements confirmed before roof sheathing covers the trusses and their bracing
  • Wide spans, unusual loads, or any non-standard condition reviewed by the truss designer or a structural engineer
Full QC Checklist+

Verify truss design inputs, truss engineering/design, bracing and installation, and installation/code compliance.

✓20 Inspection Points
✓4 Verification Categories
✓Truss Design Inputs+
  • Building span and length confirmed from actual field measurements or plans, not assumed
  • Roof pitch entered matches the actual design intent, not a rough guess
  • Truss type selected matches the actual roof design (common, scissor, attic, mono, etc.)
  • Truss spacing matches the roof sheathing/decking span rating and the actual roof load for this project
  • Calculation confirmed to represent one clear-span truss run at a time
  • Local building code edition, wind/seismic zone, and snow load confirmed before finalizing
✓Truss Engineering & Design+
  • Confirmed this calculator does NOT replace an engineered, stamped truss design — a real truss order/design was obtained separately
  • Truss placement diagram from the manufacturer matches the actual roof plan and this takeoff's count
  • Girder trusses (trusses that carry other trusses, e.g. at a valley or opening) identified and engineered separately
  • Damaged or incorrectly-cut trusses are never modified in the field without engineering approval
  • Gable end truss type (vertical-stud vs. step-down ladder) confirmed against the actual gable overhang detail
✓Bracing & Installation+
  • Temporary erection bracing planned and installed as each truss is set — before it's left unsupported
  • Permanent bracing (web member bracing, continuous lateral bracing) installed exactly per the truss designer's drawing
  • Truss-to-wall connectors (hurricane ties/truss anchors) rated for the site's actual wind/seismic uplift requirement
  • Gable end truss fastening and any required L-bracing/stiffener bracing installed per the truss drawing
  • Crane lift plan (if used) confirmed against actual truss weight, span, and site access — not assumed
✓Installation & Code Compliance+
  • Roof sheathing, underlayment, and roofing material planned and estimated separately
  • Attic/roof ventilation (soffit, ridge, or gable vents) planned to match the actual truss heel and ridge detail
  • Permit and framing inspection requirements confirmed before roof sheathing covers the trusses and their bracing
  • Wide spans, unusual loads, or any non-standard condition reviewed by the truss designer or a structural engineer
Inspection Notes+
Use the latest approved drawings, specifications, and site measurements.
Complete all critical checks before proceeding to the next work stage.
Record deviations and confirm rectification where required.

FAQ

Use it after collecting the project inputs and again before approving or closing the relevant work stage.
No. It supports verification but does not replace approved drawings, specifications, codes, manufacturer requirements, or professional inspection.
