how much nail per shingle
Estimate how many roofing nails you'll need. At 4 nails per shingle, thatâs about 320 nails per square. For high-wind areas, use 6 nails per shingle, or 480 nails per square. Inquire at the hardware store regarding the size of nail youâll need and how many pounds youâll need of that size; the number of nails per pound differs. The nails should be long enough to go Â¾ inch into the roof. Inquire at the hardware store regarding the amount of underlayment nails required. Always use 1-inch (2.5 cm) nails.
