What drives roof replacement cost?

Roofing costs are not just about shingles. A complete replacement includes tear-off, disposal, underlayment, flashing, ventilation, and labor. Here are the primary cost drivers:

  • Roof size: Measured in "squares" (100 sq ft each). A 1,700 sq ft roof is 17 squares.
  • Roof pitch: Steeper roofs require more material and labor. Pitches above 6:12 add 10-20%.
  • Material choice: Asphalt shingles are cheapest. Metal, tile, and slate cost 2-5x more.
  • Number of layers: Removing two layers of old shingles adds $30-$60 per square.
  • Accessibility: Tall homes, tight lots, and obstacles increase labor time.
  • Location: Labor rates vary 50%+ between regions. See our state-by-state cost report.

Hidden costs to budget for

  • Deck repair: Rotten plywood under old shingles costs $50-$100 per sheet to replace
  • Permits: Most municipalities require permits ($150-$500)
  • Upgraded underlayment: Synthetic underlayment adds $20-$40 per square but lasts longer
  • Ice and water shield: Required in northern climates, adds $50-$80 per square
  • Ventilation upgrades: Ridge vents or additional soffit vents improve attic life

How to save without cutting corners

  • Get 3-5 quotes from reputable, insured contractors
  • Schedule during the off-season (late fall or early spring) for potential discounts
  • Choose architectural shingles over premium designer lines — the value proposition is stronger
  • Verify manufacturer warranties require certified installers
  • Do the tear-off yourself only if you have experience and proper safety equipment
