These are blended industry averages. Real costs vary 10-25% by region, contractor overhead, code requirements (ice & water shield, drip edge, ventilation upgrades) and roof access difficulty. For an actual measurement-backed quote tied to your address, use the RidgeIQ widget — it pulls satellite imagery + property data and feeds it through a contractor's real pricing.

Roof replacement pricing is built up from three components: material cost per square, labor, and tear-off / disposal. A "square" in roofing equals 100 square feet of roof surface. So a 2,500 sqft home with a medium pitch typically has ~27 squares of roof.
A steeper roof requires more material per square foot of footprint (longer slope lengths) AND more labor (slower install, fall-protection). A simple 4-facet gable roof installs much faster than a complex 12-facet roof with multiple dormers, valleys and hips — even at the same square footage. Industry waste factors typically range from 10% (simple) to 20% (very complex).
