Roofing Nail Count by Wind Zone
Field fasteners for an asphalt-shingle roof, where the wind zone drives the nailing pattern: nails = squares x shingles-per-square x nails-per-shingle; weight = nails / nails-per-pound. A 30-square roof at 80 shingles per square, six-nailed for high wind, takes 14,400 nails - about 103 lb of 1-1/4 in roofing nails, half again the standard four-nail pattern (9,600 nails, 69 lb). The manufacturer and wind zone set the pattern; eaves and rakes get six regardless.
Formula and source
nails_total = squares x shingles_per_square x nails_per_shingle; nail_weight_lb = nails_total / nails_per_lb.
Roofing fastener-count identity by name (nails from squares x shingles x pattern; weight from nails / nails-per-pound); first-principles count arithmetic.
