Wood & Engineered Wood Siding Verification Checklist

Essential Checklist+

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

✓14 Inspection Points
✓4 Verification Categories
✓Measurement & Takeoff+
  • Every wall section's width and height were measured on site, not estimated from a floor plan alone.
  • Window and door counts and typical sizes were recorded for each wall section that has openings, not assumed uniform across the whole house.
  • Outside and inside corner counts match the building's actual footprint, including any bump-outs, bay windows, or wing additions.
  • Overall wall height (corner boards and inside-corner sealant only) reflects the tallest point they must run — separate from each wall section's own height, which drives that wall's own coursing or board run.
✓Material & Style Selection+
  • Material type (Natural Wood vs. Engineered Wood) matches the actual product being ordered, since this changes the available board widths, default finish options, and fastener type recommendation.
  • Siding style (Lap/Clapboard vs. Board & Batten) matches the actual design — switching this changes the entire calculation method, not just a label.
  • Board width selected matches the actual product ordered, not assumed from a generic default.
  • For Lap/Clapboard: overlap entered matches the installer's actual planned overlap (1 in published minimum) — this directly sets the derived reveal and course count.
  • Board/batten stock length was confirmed against the actual supplier SKU, since this calculator's 16 ft assumption may not match every supplier.
✓Finish & Fastening+
  • Finish type (Prefinished, Primed, or Unfinished) matches the actual product ordered, since this changes whether a field-paint quantity is needed.
  • Fastener TYPE is corrosion-resistant and appropriate to the material — hot-dip galvanized or stainless for natural wood (to avoid tannin staining), a standard coated siding nail acceptable for engineered wood.
✓Trim, Corners & Installation+
  • Trim (casing) boards are planned around every window and door opening (3-sided for doors, 4-sided for windows).
  • Outside corners use full-height corner boards on both faces; inside corners are butted and caulked rather than boarded.
  • Board, trim, corner, and fastener quantities including the waste allowance — not the raw calculated totals — were used for the material order.

✓Measurement & Takeoff+
  • Every wall section's width and height were measured on site, not estimated from a floor plan alone.
  • Window and door counts and typical sizes were recorded for each wall section that has openings, not assumed uniform across the whole house.
  • Outside and inside corner counts match the building's actual footprint, including any bump-outs, bay windows, or wing additions.
  • Overall wall height (corner boards and inside-corner sealant only) reflects the tallest point they must run — separate from each wall section's own height, which drives that wall's own coursing or board run.
  • Gable end walls were added as their own row with a reasonable average height, or their triangular area was measured and compared separately.
✓Material & Style Selection+
  • Material type (Natural Wood vs. Engineered Wood) matches the actual product being ordered, since this changes the available board widths, default finish options, and fastener type recommendation.
  • Siding style (Lap/Clapboard vs. Board & Batten) matches the actual design — switching this changes the entire calculation method, not just a label.
  • Board width selected matches the actual product ordered, not assumed from a generic default.
  • For Lap/Clapboard: overlap entered matches the installer's actual planned overlap (1 in published minimum) — this directly sets the derived reveal and course count.
  • For Board & Batten: board gap and batten width match the actual planned installation, not left at generic defaults.
  • Board/batten stock length was confirmed against the actual supplier SKU, since this calculator's 16 ft assumption may not match every supplier.
✓Finish & Fastening+
  • Finish type (Prefinished, Primed, or Unfinished) matches the actual product ordered, since this changes whether a field-paint quantity is needed.
  • Fastener spacing (16 in studs, 24 in max, or 12 in high-wind) matches the local code/wind-load requirement for this job, not just this calculator's default.
  • Fastener TYPE is corrosion-resistant and appropriate to the material — hot-dip galvanized or stainless for natural wood (to avoid tannin staining), a standard coated siding nail acceptable for engineered wood.
  • Waste allowance (5-15%) matches the job's actual complexity — more openings, cuts, and gables need a higher allowance.
✓Trim, Corners & Installation+
  • Trim (casing) boards are planned around every window and door opening (3-sided for doors, 4-sided for windows).
  • Outside corners use full-height corner boards on both faces; inside corners are butted and caulked rather than boarded.
  • For Board & Batten: furring/strapping behind vertical boards (if the wall needs it) and a rain-screen gap were planned separately — this calculator does not estimate that material.
  • Board, trim, corner, and fastener quantities including the waste allowance — not the raw calculated totals — were used for the material order.
  • Housewrap/weather-resistant barrier condition was confirmed intact and properly lapped before siding installation began.
  • If Primed or Unfinished finish was selected, field paint or stain was applied in the required coats before/shortly after installation.
  • Final elevation was checked for level/plumb courses or columns, consistent reveal or gap, and properly seated corner boards and trim before calling the job complete.
