A roofing square is 100 square feet. That’s the unit every roofer prices in. So when a homeowner asks me what shingles cost, I never quote per shingle or per bundle. I quote per square, because that’s how the supplier prices the material and how my crew prices the labor.
If you’re trying to figure out what your roof should run before signing a contract, you need to understand what’s actually inside that “per square” number.

Quick Answer
The cost of shingles per square in 2026 runs $300 to $900 installed for the most common asphalt options, and up to $3,000 per square for premium metal. 3-tab asphalt sits at $300 to $500 per square installed. Architectural shingles run $400 to $900 per square installed. Material alone is $70 to $250 per square for asphalt. The rest is labor, tear-off, underlayment, and accessories.
What “Per Square” Actually Includes
Most homeowners hear a per-square price and assume it’s just the cost of the shingles. It’s not. A real installed price per square covers:
- Shingle material itself (the bundles)
- Underlayment (synthetic or felt)
- Ice and water shield at eaves and valleys
- Drip edge, starter strip, ridge cap
- Nails, sealant, ridge and soffit vents
- Labor to tear off the old roof and install the new one
- Dump fees for the old shingles (this surprises homeowners every time)
- Permit fees in most jurisdictions
When a contractor quotes you $400 per square installed, all of that should be inside the number. If it’s not, you’re getting a low-ball bid that will hit you with change orders later. I’ve seen this play out a hundred times. The cheap bid leaves out tear-off and underlayment, and by the time the homeowner figures it out, the old roof is already in a dumpster.
Cost Of Shingles Per Square: Full Breakdown
Here’s how the per-square math actually pencils out by tier.
| Shingle Type | Material/Square | Labor/Square | Installed Total/Square |
|---|---|---|---|
| 3-tab asphalt | $70 - $200 | $150 - $300 | $300 - $500 |
| Architectural | $100 - $250 | $150 - $400 | $400 - $900 |
| Designer / luxury asphalt | $200 - $400 | $200 - $500 | $500 - $1,200 |
| Metal (exposed fastener) | $120 - $400 | $200 - $500 | $400 - $1,500 |
| Metal (standing seam) | $300 - $900 | $300 - $1,500 | $800 - $3,000 |
Sources: HomeAdvisor 2025-2026 roofing cost guides, Angi May 2026 architectural shingle data, BLS Occupational Employment Statistics 47-2181 (Roofers), and field experience pricing PNW jobs since 2005.
The wide range on metal is real. A basic R-panel install is closer to architectural shingle pricing. A standing seam install with hidden fasteners and custom flashing is a different animal entirely. Different crew, different time, different cost.
Material vs Labor Split
For a typical architectural shingle job, here’s where the money actually goes per square. The line items below come from current PNW supplier pricing and what I pay my crew.
| Line Item | Cost Per Square | Notes |
|---|---|---|
| Shingle material | $150 | 30-year architectural, mid-grade |
| Synthetic underlayment | $35 | GAF Tiger Paw or equivalent |
| Ice and water shield | $25 | At eaves, valleys, penetrations |
| Drip edge + starter + caps | $45 | Full perimeter |
| Nails, sealant, vents | $25 | Includes ridge vent allocation |
| Roofer labor | $250 | Tear-off and install combined |
| Dump fees | $75 | 1 ton of asphalt = ~$60-$110 dump |
| Total per square | $605 | Mid-range PNW figure |
That puts a 25-square roof at roughly $15,000 installed. Right in the middle of the national $5,000 to $45,000 range on Angi’s 2026 roof replacement data, and consistent with what I see for a 2,500 sq ft single-story PNW home.
Regional Pricing Adjustments
Per-square prices swing hard by metro. Labor cost is the biggest variable. Here’s how installed pricing adjusts versus the national average for a mid-grade architectural shingle job. Adjustments based on BLS regional roofer wage data, RSMeans 2026 city cost indexes, and field experience.
| Metro | Adjustment vs National | Architectural Installed/Square |
|---|---|---|
| New York City | +30% | $520 - $1,170 |
| San Francisco Bay Area | +28% | $510 - $1,150 |
| Seattle / PNW | +12% | $450 - $1,010 |
| Chicago | +5% | $420 - $945 |
| Atlanta | -8% | $370 - $830 |
| Phoenix | -10% | $360 - $810 |
| Dallas-Fort Worth | -7% | $370 - $840 |
Steep roofs, two-story homes, and complicated rooflines (multiple valleys, hips, dormers) add another 15 to 40 percent on top of these numbers. A simple gable runs at the low end. A cut-up roof with five intersecting planes runs at the high end. I’ve bid the same square footage on two houses three blocks apart and come in $4,000 different because of pitch and complexity alone.
Worked Example 1: 22-Square 3-Tab Tear-Off
Single-story rambler, 4/12 pitch, simple gable roof, two-tab tear-off going to a basic 3-tab replacement. Atlanta market.
| Item | Quantity | Rate | Total |
|---|---|---|---|
| 3-tab shingles | 22 squares | $90/square | $1,980 |
| Synthetic underlayment | 22 squares | $30/square | $660 |
| Ice and water shield | 4 squares | $50/square | $200 |
| Drip edge + accessories | 22 squares | $35/square | $770 |
| Tear-off + dump | 22 squares | $80/square | $1,760 |
| Labor (install) | 22 squares | $180/square | $3,960 |
| Permit + dumpster | 1 | $450 | $450 |
| Subtotal | $9,780 | ||
| Overhead + profit (20%) | $1,956 | ||
| Total | $11,736 |
Per-square installed price: $534. That lands at the high end of the national 3-tab range because of the tear-off, but it’s a fair number for a 22-square Atlanta job in 2026.
Worked Example 2: 30-Square Architectural Job
Two-story PNW home, 8/12 pitch, two valleys, one chimney, replacing 25-year-old 3-tab with 50-year architectural. Tear-off included. This is closer to my typical Pacific Remodeling roofing scope.
| Item | Quantity | Rate | Total |
|---|---|---|---|
| Architectural shingles | 30 squares | $175/square | $5,250 |
| Synthetic underlayment | 30 squares | $35/square | $1,050 |
| Ice and water shield | 6 squares | $55/square | $330 |
| Starter + drip edge + caps | 30 squares | $45/square | $1,350 |
| Ridge vent + soffit baffles | 60 lf | $7/lf | $420 |
| Chimney flashing replace | 1 | $950 | $950 |
| Tear-off + dump (3-tab + felt) | 30 squares | $90/square | $2,700 |
| Labor (steep + cut-up) | 30 squares | $310/square | $9,300 |
| Permit + dumpster | 1 | $600 | $600 |
| Subtotal | $21,950 | ||
| Overhead + profit (22%) | $4,829 | ||
| Total | $26,779 |
Per-square installed price: $893. That’s high. Steep pitch, second story, and the chimney flashing all push it. But that’s the real number for that scope in the PNW, and it’s the kind of job a low-ball bidder will quote at $18,000 by leaving out flashing and ridge vent.
What Drives Per-Square Cost Up Or Down
Stuff that makes the number bigger:
- Pitch over 6/12. Steeper means slower, riskier, more crew time
- Two-story or higher. Setup, fall protection, ladders all add hours
- Cut-up roof. Hips, valleys, dormers eat material and labor
- Old layer removal. Two-layer tear-off doubles dump weight
- Code upgrades. Some jurisdictions require ice shield to 3 ft inside the wall line
- Chimney, skylights, vents. Each penetration is hand work and flashing
Stuff that makes the number smaller:
- Simple gable. Two planes, no valleys
- Single-story. No staging or fall arrest setup
- Overlay (where allowed). Skip the tear-off
- Bigger square footage. Mobilization gets spread thinner
- Dry season scheduling. Crews work faster, no weather delays
Common Mistakes Homeowners Make
- Comparing per-square prices on different scopes. Bid A is $400/square with overlay. Bid B is $600/square with full tear-off, ice shield, and ridge vent. Those aren’t competing bids, they’re different jobs.
- Ignoring waste factor. A 22-square roof needs 24 to 25 squares of material. Cuts and overlap eat 5 to 15 percent. If your bid says exactly 22 squares of material, the contractor is going to come up short or pad the change order.
- Skipping the underlayment line. Old felt was $15 per square. Modern synthetic is $30 to $40. Ice and water shield is $50+. Underlayment is a third of the material cost on a real install, and a lot of bids hide it.
- Paying for “lifetime” warranty without checking the labor warranty. The shingle warranty covers material defects from the manufacturer. The contractor warranty covers workmanship. They are not the same thing. Ask for both, in writing.
- Choosing on price alone. I’ve said it before. The cheapest bid usually leaves something out. The honest bid usually wins long term, even if it’s not the lowest number on day one.
FAQ
How many shingles are in a square?
One roofing square equals 100 square feet. That’s typically 3 bundles of architectural shingles or 3 bundles of 3-tab shingles for most major brands (GAF, Owens Corning, CertainTeed). Always verify the bundle count on the wrapper because some heavy or designer shingles take 4 or 5 bundles per square. Source: GAF and Owens Corning packaging specs.
Why does shingle cost per square vary so much?
The bundle of shingles is only part of the per-square price. Labor, tear-off, dump fees, underlayment, and accessories make up 50 to 70 percent of the installed cost. Regional wage differences add another 30 percent swing on top. A $90 bundle in Phoenix becomes a $620 installed square in NYC because of labor.
Is it cheaper to install over old shingles?
An overlay (installing new shingles on top of old) saves $80 to $120 per square in tear-off and dump fees. But most jurisdictions only allow one layer total on top of the deck, and you can’t inspect the deck for rot underneath. I’ve pulled up overlays where the deck was soft and the homeowner had to pay twice. I quote tear-off on every job unless the existing roof is genuinely young and clean.
How much does a 2,000 sq ft roof cost in shingles?
A 2,000 sq ft house typically has a 24 to 28 square roof (after pitch adjustment). At $400 to $900 per square installed for architectural shingles, that’s roughly $9,600 to $25,200 for a full replacement. Use our roof replacement cost guide for a live estimate, or roofing calculator for a square-footage-based number.
What’s the difference between 3-tab and architectural cost per square?
3-tab asphalt runs $70 to $200 per square in material. Architectural runs $100 to $250 per square in material. Installed, the gap widens because architectural is heavier and slower to install. Most homes today get architectural because the warranty doubles, the wind rating climbs to 130 mph, and the curb appeal is meaningfully better. The $100 to $400 per-square upcharge over 3-tab is worth it on almost every job I bid.
Pulling It Together
Cost of shingles per square is not one number. It’s a stack: material, underlayment, accessories, tear-off, labor, dump fees, overhead. When you understand what’s inside the number, you can read a bid honestly and tell the difference between a real estimate and a low-ball that’s about to change-order you to death.
