Quick answer: A bundle of shingles is a single packaged unit that covers about 33.3 square feet of roof, so it takes three bundles to cover one roofing square (100 square feet). A bundle holds 15 to 29 shingles depending on type, weighs 50 to 80 pounds, and costs roughly $30 to $60 for standard asphalt, or far more for luxury lines. (A “pack of shingles” is just another name for a bundle.)
That covers the essentials. Below, we break down counts, coverage, weight, and cost by shingle type, then walk through exactly how to calculate how many bundles your roof needs. If you would rather skip the math, our roof cost calculator estimates materials for your home in seconds.
How Many Shingles Are in a Bundle?
The count depends on the shingle’s thickness and weight, because manufacturers keep coverage roughly consistent at 33.3 square feet per bundle regardless of type.
| Shingle Type | Shingles per Bundle | Coverage per Bundle | Bundles per Square |
|---|---|---|---|
| 3-tab | 26-29 | ~33.3 sq ft | 3 |
| Architectural | 20-22 | ~33.3 sq ft | 3 |
| Luxury / specialty | 10-16 | 20-25 sq ft | 4-6 |
3-tab shingles are the thinnest and lightest, so they pack the most per bundle, usually 26 to 29. Architectural (dimensional) shingles are thicker, so they run 20 to 22 per bundle. By brand, that means about 21-22 for CertainTeed Landmark, 20-22 for GAF Timberline HDZ, and at least 20 for Owens Corning Duration and TAMKO Heritage. If you are unsure which profile you have, our guide on architectural shingles vs. 3-tab explains the difference.
Luxury shingles are heaviest and have the lowest count, typically 10 to 16 per bundle. CertainTeed Grand Manor has 10, Belmont has 12, and GAF Slateline has 16. These also cover less area per bundle, so they need more bundles per square; our look at the best luxury asphalt shingles covers the trade-offs.
How Much Area Does a Bundle Cover?
A standard asphalt bundle, whether 3-tab or architectural, covers about 33.3 square feet. That is the number behind the industry’s whole measurement system: since a roofing square is 100 square feet, three bundles equal one square. If the term “square” is new to you, our explainer on the roofing square breaks it down.
Luxury shingles are the exception, covering less per bundle. CertainTeed Belmont and IKO Crowne Slate cover about 25 square feet, while Grand Manor and IKO Armourshake cover about 20.
How Much Does a Bundle of Shingles Weigh?
A standard asphalt bundle weighs 50 to 80 pounds, light enough for one person to carry up a ladder safely. That weight range is the reason shingles are bundled at all: a full square (100 square feet) at once would be too heavy and unwieldy to handle, so manufacturers split it into three manageable packages that also protect the shingles during shipping and storage.
How Much Does a Bundle of Shingles Cost?
Pricing varies by type and quality. As a rough current guide:
| Shingle Type | Cost per Bundle |
|---|---|
| 3-tab asphalt | ~$30-$45 |
| Architectural asphalt | ~$40-$60 |
| Luxury / designer | $60-$150+ |
| Cedar / wood | $200-$330 |
These are material-only figures; installed cost is higher once labor, underlayment, and accessories are included. For the full picture on a real project, see our breakdown of the cost of an asphalt roof.
How to Calculate How Many Bundles You Need
The formula is simple:
- Find your roof area in square feet.
- Divide by 100 to get roofing squares.
- Multiply by 3 for standard shingles, then round up.
- Add 10-20% waste for cuts, valleys, and mistakes.
Worked Example: 1,850 sq ft roof
1,850 ÷ 100 = 18.5 squares, rounded up to 19. Then 19 × 3 = 57 bundles before waste.
Worked Example: 1,000 sq ft roof
1,000 ÷ 100 = 10 squares. Then 10 × 3 = 30 bundles, plus 3 to 6 extra bundles for a 10-20% waste factor.
Don’t Forget Roof Pitch
A steeper roof has more surface area than its footprint suggests, so multiply your flat area by a pitch factor before converting to squares.
| Roof Pitch | Area Multiplier |
|---|---|
| 4/12 | 1.054 |
| 6/12 | 1.118 |
| 8/12 | 1.202 |
| 12/12 | 1.414 |
For example, a 20-by-40-foot home (800 sq ft footprint) with a 7/12 pitch works out to about 800 × 1.16 = 928 square feet of actual roof. Understanding pitch matters for budgeting too; see how roof pitch affects the cost of a replacement.
Add a Waste Factor
Even perfect measurements need extra material. Simple roofs need 10 to 15% more; roofs with lots of valleys, hips, and penetrations can need up to 20%. This covers cutting, damaged pieces, and installer error, and prevents the costly mid-job shortage that stalls a project.
The Bottom Line for Portland Homeowners
A bundle of shingles covers about 33.3 square feet, takes three to make a square, holds 15 to 29 shingles by type, and weighs 50 to 80 pounds. To estimate your project, find your roof area, divide by 100, multiply by three, adjust for pitch, and add a 10-20% waste factor.
Getting that count right is exactly the kind of detail that separates a smooth roof replacement from an over-budget one.

FAQs
How many shingles are in a bundle?
It depends on type: 3-tab bundles hold 26-29 shingles, architectural hold 20-22, and luxury shingles hold just 10-16 because they are thicker and heavier.
How many square feet does a bundle of shingles cover?
A standard asphalt bundle covers about 33.3 square feet, so three bundles cover one roofing square (100 square feet). Luxury shingles cover 20-25 square feet per bundle.
How much does a bundle of shingles weigh?
A standard asphalt bundle weighs 50 to 80 pounds, light enough for one person to carry, which is why a full square is split into three bundles.
How many bundles do I need for 1,000 square feet?
About 30 bundles for standard shingles (10 squares times 3), plus 3 to 6 extra for a 10-20% waste allowance.
What is a pack of shingles called?
A pack of shingles is simply called a bundle. It is the standard packaged unit suppliers use, with three bundles making up one roofing square.
How much does a bundle of shingles cost?
Material cost runs about $30-$45 for 3-tab, $40-$60 for architectural, and $60-$150 or more for luxury lines, with wood shingles higher still. Installed cost is more.
