1,500 sq ft roof replacement cost
Baseline scope: architectural asphalt shingle, standard pitch, simple gable, one story, one layer torn off. Change any of that in the calculator to fit your roof.
Research-preview estimate
$15,800
Illustrative pricing estimate for 1,500 sq ft of roof surface (15 roofing squares).
This range still relies on pricing assumptions that require source verification. It shows how the calculation engine treats your roof, not a validated market price. Use it to understand the shape of the cost, and treat contractor quotes as the authority on price until these assumptions are verified.
Price per square foot
$7.00 – $15.65
Price per roofing square
$700 – $1,565
Preliminary confidence
- Decking condition is unknown, so a 10% replacement allowance was assumed.
- This material has no verified material-cost and installation-labor split yet, so the base price is a single installed range and regional labor conditions could not be applied to it. Applying a wage index to an installed price would incorrectly scale material cost as well.
- At least one pricing assumption used by this estimate has not been source-verified yet, so this is a research-preview range rather than a validated market price.
Area basis: Measured roof area you entered. No regional labor index was applied: this material has no verified material/labor component split, and indexing a combined installed price by local wages would incorrectly scale material cost too.
Pricing assumptions require source verification
The unit costs, regional index and adjustment multipliers behind this estimate are currently labeled DEMO / PLACEHOLDER. They exist so the calculation engine, methodology and source registry can be reviewed end to end. They are not published market prices, and every value is editable in the pricing database once verified data is loaded.
