TL;DR
A nail pattern is the prescribed count and placement of fasteners for each shingle, siding panel, or sheathing sheet, set by the manufacturer and the building code for the wind exposure. Asphalt shingles typically take four nails on the factory line, stepping up to six in high-wind regions; sheathing has its own edge and field spacing schedule.
What it means
A nail pattern is the prescribed count and placement of fasteners for each shingle, siding panel, or sheathing sheet, set by the manufacturer and the building code for the wind exposure. Asphalt shingles typically take four nails on the factory line, stepping up to six in high-wind regions; sheathing has its own edge and field spacing schedule. Inspectors and warranty adjusters check it after failures, since wrong placement — high nailing especially — is among the most common installation defects.
