Roof Replacement Cost Estimator
These are rough national averages. Real quotes vary widely by region, local labor rates, roof complexity (valleys, dormers, chimneys), tear-off vs. overlay, decking condition, permit fees, and material sub-type. Always get 2–3 quotes from local licensed roofers before making a decision.
What Drives the Price of a New Roof?
Material is the headline number, but it's rarely the biggest swing. The same 2,000 sq ft asphalt-shingle roof can quote at $10K in one market and $18K in another based on labor rates alone. Add a steep pitch, a complex hip-and-valley layout, or decking replacement, and the range widens further.
- Material: asphalt is the cheapest; metal, tile, and slate scale up quickly.
- Pitch: steeper roofs require more safety setup and slower work, which contractors price in.
- Tear-off: removing old layers adds labor and disposal cost vs. overlaying.
- Decking: rotted plywood found during tear-off is a common upcharge.
- Region: labor rates and permit costs vary dramatically city to city.
- Warranty tier: premium manufacturer warranties often require certified installers at higher labor rates.
