1 square = 100 sq ft. Divide your total roof area by 100.
📋 Important: All calculator results are ballpark estimates
The figures shown are approximate estimates based on typical averages and should be used for general planning purposes only. They are not a substitute for a professional assessment or written contractor quote. Actual costs, savings, and results will vary significantly based on your specific circumstances, local market conditions, equipment choices, and contractor pricing. Always confirm any estimate with a licensed contractor, financial advisor, or qualified professional before making purchasing or financial decisions.
How Roofing Labor Costs Are Set
Labor is quoted per square, not per hour
Roofing contractors almost always price labor by the roofing square (100 sq ft of roof surface), not by the hour. This lets them bid predictably regardless of crew size or how fast the job goes. When comparing bids, make sure you understand what's included in each line item — some contractors bundle tear-off and installation; others break them out separately.
Pitch is the biggest variable in labor cost
A roof with a 12:12 pitch (45-degree angle) requires fall protection equipment, slower pace, and often additional crew members compared to a 4:12 pitch. The extra safety time and physical difficulty add 20–50% to labor on steep roofs. If you have a steep roof, always get bids from contractors with steep-slope experience — it's a specialty that commands a premium for good reason.
Tear-off adds a meaningful line item
Most local codes allow one re-roof (installing new shingles over existing), but two layers must be torn off before a new install. A two-layer tear-off adds roughly $50–$70 per square in labor versus no tear-off. It also increases the disposal cost (dumpster and dump fees), which may be billed separately.
What's never included in a labor-only estimate
- Roofing materials (shingles, underlayment, ridge cap, starter strip)
- Decking replacement for rotted or damaged boards
- Flashing at chimneys, walls, skylights, or plumbing penetrations
- Gutters or gutter guards
- Permit fees ($150–$500 depending on jurisdiction)
- Disposal / dumpster fees if not bundled into the bid

How much does roofing labor cost per square?
Roofing labor typically costs $150–$300 per square (100 sq ft) for a standard asphalt shingle job. That range widens based on roof pitch, complexity, region, and whether tear-off of old shingles is included. Steep or complex roofs can push labor to $350+ per square.
Is tear-off labor included in the per-square rate?
It depends on the contractor. Many roofing bids show labor as a single per-square figure that includes tear-off and installation. Others break it out separately — typically $35–$65 per square for tear-off of one layer. Always confirm what's included in any quote you receive.
How long does it take to roof a house?
A typical 25–30 square residential roof takes a crew of 3–4 workers one full day on a simple, moderate-pitch job. Complex roofs with dormers and skylights, or very steep pitches, can take 2–3 days. Larger homes (40+ squares) typically take 2 days minimum.
What's not included in a roofing labor estimate?
Labor estimates typically cover installation of shingles, underlayment, and ridge cap. Not usually included: decking replacement ($2–$4/sq ft for rotted boards), new flashing at chimneys or walls, gutters, skylights, or ventilation upgrades. Get a line-item quote to see exactly what's covered.
Why do steep roofs cost more in labor?
Steep roofs require safety equipment (harnesses, scaffolding), slow down the crew's work pace, and increase fall risk. Contractors factor in longer job duration, higher insurance costs, and additional materials like steep-slope underlayments. Very steep roofs (13:12+) can cost 40–50% more in labor than a standard 6:12 pitch.
