House Wrap 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
✓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.
  • Roll size selected matches the actual product being purchased, not left at the default without checking the supplier's catalog.
✓Roll & Overlap Planning+
  • Horizontal (course-to-course) lap overlap matches the specific house wrap product's own installation instructions, not assumed from this calculator's default alone.
  • Roll count for ordering includes this calculator's waste allowance, not the raw unadjusted course length.
  • Starting course begins at the bottom of the wall so every subsequent course sheds water downward and outward over the one below.
✓Fasteners & Tape+
  • Fastener type (cap nails vs. cap staples) matches the product specified by the house wrap manufacturer for the substrate being fastened into.
  • Fastener spacing (both framing O.C. and vertical spacing) matches the manufacturer's published installation instructions for the wind exposure/zone, not assumed.
  • Seam tape is planned for every horizontal lap AND every vertical splice, not just the horizontal seams.
  • Flashing tape is planned at every window and door opening — head, both jambs, and sill — before the next course is installed over it.
✓Installation & Final Check+
  • No housewrap was installed over wet or unacceptably out-of-tolerance sheathing — the substrate was dry and sound before wrapping.
  • Every seam, splice, and flashing-taped opening was pressed/rolled firmly so the tape's adhesive fully engages, not just laid in place.
  • Any tears, punctures, or fastener mis-hits were patched with matching tape before the siding/furring was installed over them.

✓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.
  • Wall sections match the building's actual elevations, including any bump-outs, gables, or additions entered as their own rows.
  • A triangular gable end was entered with a reasonable average height, or its area was measured separately.
  • Roll size selected matches the actual product being purchased, not left at the default without checking the supplier's catalog.
  • Framing spacing and fastener vertical spacing match the actual stud layout and product instructions, not just this calculator's defaults.
✓Roll & Overlap Planning+
  • Horizontal (course-to-course) lap overlap matches the specific house wrap product's own installation instructions, not assumed from this calculator's default alone.
  • Vertical/end lap overlap at any splice joint is planned and communicated to the install crew — this calculator's splice and roll counts already account for it wherever a course needs splicing.
  • Roll count for ordering includes this calculator's waste allowance, not the raw unadjusted course length.
  • Starting course begins at the bottom of the wall so every subsequent course sheds water downward and outward over the one below.
  • Each wall's own course count and seam locations were checked against the actual roll width being purchased, not assumed from a different roll size.
✓Fasteners & Tape+
  • Fastener type (cap nails vs. cap staples) matches the product specified by the house wrap manufacturer for the substrate being fastened into.
  • Fastener spacing (both framing O.C. and vertical spacing) matches the manufacturer's published installation instructions for the wind exposure/zone, not assumed.
  • Seam tape is planned for every horizontal lap AND every vertical splice, not just the horizontal seams.
  • Flashing tape is planned at every window and door opening — head, both jambs, and sill — before the next course is installed over it.
  • Flashing tape sequence follows a shingle-style order (sill first, then jambs, then head) so water sheds outward at every layer.
  • Tape and fastener box/roll quantities including the waste allowance — not the raw calculated totals — were used for the material order.
✓Installation & Final Check+
  • No housewrap was installed over wet or unacceptably out-of-tolerance sheathing — the substrate was dry and sound before wrapping.
  • Every seam, splice, and flashing-taped opening was pressed/rolled firmly so the tape's adhesive fully engages, not just laid in place.
  • Manufacturer-specified exposure time limits (if any) for leaving the wrap exposed to UV/weather before siding installation were checked and scheduled around.
  • Any tears, punctures, or fastener mis-hits were patched with matching tape before the siding/furring was installed over them.
  • This calculator's planning-level estimate — not the as-built wrap — was reconciled against the actual material used, and the difference investigated if large.
  • Local building code's water-resistive barrier requirement (e.g. IRC R703.2) and the product's own installation instructions were both confirmed before final sign-off.
