How this calculator works
Most roof calculators ask for your ZIP and spit out one number. Ours shows the math: base installed cost per square foot for your material, adjusted for your roof's pitch, shape, and your state's labor rates - plus tear-off, permits, and a 10% decking contingency, each as its own line item.
What affects your roof cost most
- Material - the biggest lever: 3-tab asphalt (~$4-6/sq ft installed) vs. standing seam metal ($10-16) vs. slate ($15-28).
- Pitch - a 10/12 roof can cost 60% more in labor than a walkable 5/12.
- State - roofer wages run ~0.8x to 1.45x the national median by state (BLS, May 2025).
- Tear-off layers - each old layer adds $39-85 per square to remove.
