Quick answer: architectural shingles are packaged 3 bundles per "square," and one square covers 100 square feet of roof. Take your roof area in square feet, divide by 100, add 10–15% for waste, and multiply by 3. A typical 2,000 sq ft roof needs about 66–69 bundles.
At our price of $29 per bundle ($87 per square), that same roof costs about $1,900–$2,000 in shingles — compared to $3,500–$5,000+ for the identical product at retail. Here's how to run the numbers for your own roof.
Step 1: Figure Out Your Roof Area
You don't need to climb on the roof. Two easy options:
The footprint method. Take your home's footprint (length × width, including eaves) and multiply by a pitch factor:
| Roof pitch | Multiply footprint by |
|---|---|
| 4/12 (low) | 1.06 |
| 6/12 (average) | 1.12 |
| 8/12 (steeper) | 1.20 |
| 10/12 (steep) | 1.30 |
Example: a 30' × 50' home (1,500 sq ft footprint) with a 6/12 pitch → 1,500 × 1.12 = 1,680 sq ft of roof.
The satellite method. Free tools that measure your roof from aerial imagery get you close enough for an estimate. For ordering, always confirm with a tape measure or your roofer's measurement.
Step 2: Convert to Squares and Add Waste
Roofing is sold by the square = 100 sq ft.
- 1,680 sq ft ÷ 100 = 16.8 squares
- Add waste: 10% for a simple gable roof, 15% for a roof with hips, valleys, or dormers
- 16.8 × 1.15 = 19.3 → round up to 20 squares
Step 3: Convert to Bundles and Price It Out
- 20 squares × 3 bundles = 60 bundles
- 60 bundles × $29 = $1,740
For comparison, the same 20 squares at typical retail pricing ($40–$45/bundle) runs $2,400–$2,700 — and that's before contractor markup.
Don't Forget the Rest of the Roof
Shingles are the big line item, but a complete roof also needs:
- Starter strip — along eaves and rakes (or cut your own from 3-tab)
- Ridge cap shingles — measure your ridge and hip lines in linear feet
- Underlayment — synthetic felt, sold in rolls covering ~10 squares
- Ice & water shield — required along eaves in Utah, Idaho, and Colorado code zones
- Drip edge, nails, and vents
Rule of thumb: accessories add 15–25% on top of your shingle cost.
Why Are These Shingles $29 a Bundle?
These are B-grade architectural shingles from the same manufacturers you know — Malarkey, Owens Corning, and IKO. "B-grade" doesn't mean defective; it means off-spec, usually a subtle color variance you can't spot side by side. Same construction, same wind ratings, roughly half the price. We break this down fully in The Only Difference Between A-Grade and B-Grade Shingles.
FAQ
How much does a bundle of shingles cover?
One bundle of architectural shingles covers about 33.3 sq ft (one-third of a square).
How many bundles do I need for a 1,500 sq ft roof?
1,500 sq ft = 15 squares. With 10–15% waste, order 17 squares = 51 bundles (about $1,479 at $29/bundle).
How much does it cost to shingle a 2,000 sq ft house in Utah?
Materials at wholesale: roughly $1,900–$2,400 including accessories. With professional labor, expect $6,000–$11,000 total. DIY or roofer-supplied-by-you saves the material markup.
Should I order extra bundles?
Yes — keep 1–2 extra bundles from the same lot for future repairs. Color-matching later is much harder.
Can I return unopened bundles?
Ask us about current lot availability and return policy before you order — inventory moves fast at these prices.
The Bottom Line
Measure your footprint, apply the pitch factor, add 10–15% waste, and multiply by 3 to get your bundle count. At $29/bundle, most homeowners save 40–50% on shingles alone.
