Roofing Nails Calculator

Pounds & Count for Asphalt Shingle Installs

The Roofing Nails Calculator tells you how many pounds of nails to buy for a shingle install. Most asphalt shingles use 4 nails per shingle (6 nails in high-wind zones), and there are roughly 320 nails per pound of standard 1-1/4" galvanized roofing nails. Enter your bundle count and the tool returns total nails and pounds. Use the result alongside our Shingles, Ridge Cap, and Starter Strip calculators to put together a complete materials list before you head to the supply yard.
