About 88 nails per bundle of architectural shingles on a four-nail pattern, or 132 on a six-nail high-wind pattern. Architectural shingles run about 66 per square over three bundles, which is 22 shingles per bundle.
Quick answer: a bundle of architectural shingles holds ~21 shingles, and the standard 4-nail pattern uses ~84 nails per bundle. The 6-nail high-wind pattern bumps that to 126 nails per bundle. Use the calculator below to convert bundles → exact nail count, weight, and box count.
A bundle of shingles covers about a third of a square, so the nails per bundle follow directly from the nails per square divided by three. What changes the answer is the shingle type and the nailing pattern.
| Shingle type | Shingles per bundle | 4-nail pattern | 6-nail high-wind |
|---|---|---|---|
| Architectural (3 bundles/square) | 22 | 88 | 132 |
| Three-tab (3 bundles/square) | 26 | 104 | 156 |
| Heavyweight designer (4 bundles/square) | 16 | 64 | 96 |
Architectural shingles run about 66 to the square and three-tab about 80, which is where the per-bundle figures come from. Check the wrapper — bundles per square varies by product line.
| Roof area | 4-nail pattern | Weight | 6-nail high-wind | Weight |
|---|---|---|---|---|
| 1,000 sq ft | 2,640 | 18.9 lb | 3,960 | 28.3 lb |
| 1,500 sq ft | 3,960 | 28.3 lb | 5,940 | 42.4 lb |
| 2,000 sq ft | 5,280 | 37.7 lb | 7,920 | 56.6 lb |
| 2,500 sq ft | 6,600 | 47.1 lb | 9,900 | 70.7 lb |
| 3,000 sq ft | 7,920 | 56.6 lb | 11,880 | 84.9 lb |
Weights assume roughly 140 nails to the pound for 1¼ inch roofing nails. Longer nails weigh more each, so a 1¾ inch nail runs nearer 105 to the pound.
None — nails are bought separately. What you need per bundle is about 88 nails for architectural shingles on a four-nail pattern, or 132 on a six-nail high-wind pattern.
About 320 on the standard four-nail pattern and 480 on the six-nail high-wind pattern, assuming architectural shingles at roughly 66 per square.
Roughly 140 one-and-a-quarter inch roofing nails to the pound. A 2,000 square foot roof on a four-nail pattern needs about 5,300 nails, which is around 38 pounds.
In high-wind zones, on steep slopes, and wherever the shingle manufacturer requires it for the wind warranty to stand. The extra nails cost a few dollars a square.
