Wall / Roof Sheathing Panel and Nail Takeoff
Sheathing panels and nails for a wall or roof.
Example
You enter
- Area to sheathe (ft²) 1600
- Waste allowance (percent) 8
- Panel area (ft², 32 for a 4x8) 32
- Nails per panel from the schedule 60
You get
- Sheathing panels 54 sheets
- Nails to order 3,240
No published worked example is on file for this calculation. It is checked against a hand-worked derivation of its method and an independent reference test.
Details, formula, and sources
Scopesheets = ceil(area x (1 + waste) / sheet area); nails = sheets x nails-per-sheet. A 1,600 sf wall at 8% waste is 54 sheets, and at a 6-in edge / 12-in field pattern (~60 nails a sheet) that is 3,240 nails; a tight shear-panel schedule (~104 nails) raises it about 73%, to 5,616 on the same 54 sheets. The nailing schedule, not the area, drives the fastener order. Distinct from the plywood-span rating.
Formula or tablesheets = ceil(area_sf x (1 + waste_pct/100) / sheet_sf); nails = sheets x nails_per_sheet.
Source and editionSheathing panel / nail takeoff identity by name (sheets from area over panel area; nails from the schedule); first-principles count arithmetic.
Free accessThe takeoff is public quantity arithmetic; the nailing schedule comes from the plans and the code (entered here, not reproduced).
