How Much Does a Bundle of Shingles Cover?

Last updated: 2026-06-03 by Ted Sellers, Owner

How much does a bundle of shingles cover? A standard bundle covers 33⅓ square feet — that’s three bundles per roofing square. A bundle of asphalt shingles covers 33⅓ square feet. Three bundles equal one roofing square (100 square feet). That’s the answer for standard 3-tab and architectural shingles, which is what 95% of the roofs in the Twin Cities are using. If you’re doing the math for a re-roof, that’s the number you need. The rest of this post is about the parts of the math that trip homeowners up — the ones that lead to a second trip to the supply yard halfway through a Saturday job. I’m Ted Sellers. I run Sellers Roofing in Arden Hills, MN (license #803862), and I’ve been writing material orders for residential roofs in St. Paul, Minneapolis, and the suburbs for over 18 years. The square footage on the bundle wrapper is the easy part. Let me walk through the parts that matter.

How the 33⅓ sq ft number works

A roofing square is 100 square feet. The industry decided a long time ago that one square should equal three bundles, because anything heavier than ~75 pounds gets miserable to carry up a ladder. Split 100 by 3 and you get 33.33 — rounded to 33⅓ on most product sheets. So:

• 1 bundle = 33⅓ sq ft
• 3 bundles = 1 square = 100 sq ft
• 1 pallet = typically 42 bundles = 14 squares = 1,400 sq ft

That last one matters if you’re ordering a full house. Supply yards in the metro deliver by the pallet, and 14 squares is enough for most ramblers, town homes, and detached garages combined.

When 33⅓ is the wrong number

There are three situations where the 33⅓ figure breaks down. These are the ones I see people miss. 1. Heavy architectural shingles. A few premium lines — GAF Grand Sequoia, CertainTeed Grand Manor, Owens Corning Berkshire — are thicker and heavier per square foot. These ship at 4 bundles per square, not 3. The bundle still covers about 25 sq ft instead of 33⅓. Always check the wrapper before you count, because if you assume 3 and the product is a 4-bundle line, you’ll be 25% short. 2. Designer shingles with thick tabs. Same idea. Anything called “designer” or “luxury” by the manufacturer is worth a second look. The Atlas StormMaster Slate, for example, runs at 4 bundles per square. 3. Starter strips and hip-and-ridge. Bundles labeled as “starter course” and “hip/ridge” cover much less than 33⅓ — usually 100-120 linear feet of starter, or 20-25 linear feet of ridge cap. Don’t count those as field bundles. If you’re buying anything other than a standard 3-tab or mid-grade architectural, read the wrapper. Don’t guess.

How to count bundles for your roof

Forget calculators for a minute. Here’s the field method I teach the helpers on my crews:

1. Get the roof’s square footage. For a simple gable, that’s (length × width × pitch factor). For most metro homes with a 6/12 to 8/12 pitch, the multiplier is 1.118 to 1.202 off the ground footprint.
2. Divide by 100 to get squares.
3. Multiply by 3 for bundle count.
4. Add 10–15% for waste. Cuts, valleys, and dumb mistakes happen. On a complex roof with multiple hips and dormers, push that to 20%.

Worked example, real numbers from a Roseville roof I quoted last month:

• Ground footprint: 26’ × 48’ = 1,248 sq ft
• 7/12 pitch factor: ×1.158 = 1,445 sq ft of roof
• Squares: 14.45
• Bundles at 3/square: 43.4 → round up to 44
• Waste at 12%: +5.3 → 50 bundles ordered

The actual install took 47 bundles. The extra 3 went home with the homeowner for future repairs.

Common bundle counts by roof size

For quick gut-check estimating. These assume a standard architectural shingle at 3 bundles per square, with 12% waste added in.

Roof size	Squares	Bundles to order
1,000 sq ft	10	34
1,500 sq ft	15	51
2,000 sq ft	20	68
2,500 sq ft	25	84
3,000 sq ft	30	101
3,500 sq ft	35	118

These numbers are field-tested but they assume a relatively simple roof. Complex roofs with lots of cuts, valleys, dormers, and chimneys eat bundles faster. If your roof has more than two valleys or three dormers, bump waste up to 18%.

What 33⅓ sq ft does NOT include

A bundle covers 33⅓ square feet of field shingles only. It does not include:

• Underlayment (felt or synthetic) — separate product
• Ice and water shield — separate product, required by Minnesota code at eaves and valleys
• Drip edge — sold by the 10-ft piece
• Starter strip — separate bundle
• Hip and ridge cap — separate bundle
• Flashing — sold by the piece

When I write a material order for a 14-square house, the shingle bundles are usually less than 60% of the line items. Don’t forget the rest.

Why bundles aren’t 100 sq ft each

I get asked this a lot. The answer is weight. A single bundle at 33⅓ sq ft already weighs 60–80 pounds depending on the shingle weight class. A 100 sq ft bundle would be 180+ pounds — nobody can carry that up a ladder safely. Splitting a square into three bundles is a workplace-safety decision the industry made 50+ years ago, and it’s stuck.

What about 3-tab shingles?

Same coverage. A bundle of 3-tab shingles also covers 33⅓ sq ft. The shingles themselves are thinner and lighter, but the bundle is sized the same so the math stays consistent across product lines. 3-tab shingles cost less but only last 15–20 years in Minnesota’s hail climate. Architectural shingles last 25–30 with the same warranty terms and aren’t much more expensive. For most homeowners in St. Paul and Minneapolis, architectural is the better long-term value.

Buying tips from the field

A few things I’ve learned the hard way:

• Order from one batch. Color lots vary. If you order 50 bundles, ask the yard to pull them from the same delivery so the color matches edge to edge.
• Get the bundles tarped if they sit overnight. Asphalt softens in heat and water can run between the cellophane and the bundle.
• Check the date code on the wrapper. Most shingle warranties start from manufacture date, not install date. Don’t accept bundles more than 12 months old without a discount.
• Save 1–2 bundles after install. Future repairs will need exact matches. Store them flat in a dry garage.

Frequently asked questions

How many square feet does one bundle of shingles cover?

A standard bundle of asphalt shingles covers 33⅓ square feet. Three bundles equal one roofing square (100 square feet). Heavier designer shingles may ship at 4 bundles per square instead of 3.

How many bundles of shingles do I need for a 1,500 sq ft roof?

About 51 bundles. That’s 15 squares × 3 bundles/square = 45 bundles for the field, plus 12% waste (6 bundles) for cuts, valleys, and repairs.

How much does a bundle of shingles weigh?

A standard bundle weighs 60–80 pounds. 3-tab bundles are on the lighter end (around 60 lbs). Architectural bundles run 65–80 lbs. Heavy designer shingles can hit 90 lbs per bundle, which is why those products ship at 4 bundles per square instead of 3.

How many bundles are on a pallet?

Most pallets carry 42 bundles, which equals 14 roofing squares (1,400 sq ft). Some heavy designer lines ship 33–36 bundles per pallet.

Do I need to add waste to my bundle count?

Yes. Always add 10–15% for waste on a simple roof, and 18–20% on complex roofs with multiple valleys, hips, or dormers. The leftover bundles double as future repair material.

What’s the difference between a bundle and a square?

A square is a unit of roof area (100 sq ft). A bundle is a unit of packaging. One square equals three standard bundles. Squares are how roofers price the job; bundles are how supply yards ship the product.
