Shingles per bundle by type
Manufacturers list shingles per square rather than per bundle. We divide by the three bundles in a square for the per-bundle figure, so treat it as an average: real bundles can differ by a piece.
| Product | Bundles per square | Pieces per square | About per bundle | Per bundle covers |
|---|---|---|---|---|
| GAF Timberline HDZ (architectural) | 3 | 64 | 21.3 | 33.3 sq ft |
| GAF Royal Sovereign (3-tab) | 3 | 79 | 26.3 | 33.3 sq ft |
GAF's Timberline HDZ is listed at 64 pieces per square and three bundles per square (its blog also says Woodland uses four bundles and 56 pieces per square). GAF's Royal Sovereign data sheet lists 3 bundles and 79 pieces per square. Other brands and lines differ, so look for "pieces per bundle" or "bundles per square" on the wrapper.
Starter strip and ridge cap bundles
| Product | Pieces per bundle | Covers |
|---|---|---|
| GAF Seal-A-Ridge cap | 45 | 25 linear ft |
| GAF Pro-Start starter strip | not listed | 120.33 linear ft |
Why it matters
Counting individual shingles only matters for nail counts and small repairs. For ordering, use squares and bundles: the bundles in a square page has a table by roof size, and the calculator above adds your waste. The roofing nails calculator uses the pieces-per-square figures.
