Roof replacement cost calculator
Roof replacement runs $4 to $11 per square foot nationally in 2026. This calculator turns your home’s size, pitch, and material into a realistic range using the same math estimators use — so you can spot a padded quote before you sign it.
Estimated replacement cost
$11,300 – $17,500
- Roof area (incl. waste)
- 2,504 sq ft (26 squares)
- Per square (100 sq ft)
- $433 – $674
National-survey math, not a quote — local labor, decking repairs, and permits move real bids. If storm damage is behind this, prequalify your roof before paying out of pocket — insurance may owe part of it.
How this estimate works
Your roof is larger than your home’s footprint because it slopes. We divide living area by stories to get the footprint, apply the standard pitch multiplier estimators use (1.054 for low slopes up to 1.302 for very steep ones), add a waste allowance for cuts, then price the result against installed per-square-foot ranges from 2026 national cost surveys. Steep pitches add a $1,000–$3,000 labor premium for fall protection and staging.
