What does the price per bundle of architectural shingles actually tell you?
Short answer. Per-bundle prices for architectural shingles change with the product line, color, supplier and season, so the only reliable number is a current local quote. A bundle price tells you less than it seems: most architectural lines take three bundles per 100 square feet, heavier designer lines can take more, and the shingles are only part of what a finished roof costs.
Converting a bundle price
- Bundles per square. Most standard architectural shingles come three bundles to a square of 100 square feet. Some premium and designer lines take four or five, so compare price per square, not per bundle.
- Waste. Roofers add roughly 10 to 15 percent for cuts at valleys, hips and rakes, more on cut-up roofs.
- Accessories are separate. Starter strips and hip and ridge cap come in their own bundles, each covering a set number of linear feet printed on the wrapper, and ridge cap usually costs more per bundle than field shingles.
Why the bundle price is not the roof price
Field shingles are one line on an estimate. Tear-off and disposal, underlayment, leak barrier, drip edge, flashing, pipe boots, ventilation, labor, permits and decking repairs make up much of a full replacement, which in North Georgia typically runs roughly $8,000 to $16,000. Two roofs using the same shingle can differ widely in total cost because of pitch, layers and complexity.
Reading bundle counts on an estimate
- Check that the field shingle squares match the measured roof area plus a reasonable waste factor.
- Look for starter and hip and ridge listed separately, not just "included" with no count.
- On insurance estimates, shingle quantities and waste follow the measured roof report; see Xactimate roof estimates explained.
