How this Roof Replacement Cost Calculator Works
This roof replacement cost calculator turns your roof size and material choice into a material, labor, and total cost estimate.
- Roof area converts from square feet into roofing squares (1 square = 100 sq ft)
- Material cost uses your selected material’s typical price per square foot, or your own custom rate
- Labor cost is estimated using standard installation rates for the selected material
- Material and labor are combined for your total estimated cost

Roof Pitch Calculator FAQs
Most homeowners spend roughly $8,000–$30,000 for a full roof replacement with standard materials, depending on roof size, material, pitch, and local labor rates. Premium systems like metal, tile, or slate often run well beyond that range. This roof cost calculator narrows the estimate using your specific project details.
Asphalt shingles typically run $4–$10 per square foot installed, metal $8–$16, and tile or slate $12–$30 or more, depending on your region and roof complexity.
Yes. Steeper pitches increase the total roof surface area and installation difficulty, which raises both material and labor costs. Use our roof pitch calculator to find your roof’s pitch before estimating cost.
Asphalt shingles are typically the most affordable option upfront, though metal and tile can cost less over time thanks to their longer lifespans.
Material cost covers the shingles, panels, tile, or other roofing product itself. Labor cost covers installation — including tear-off, underlayment, and finishing work — and is typically priced per square.
Yes. This calculator estimates both material and labor cost separately, then combines them into a total estimated roof cost.
This calculator provides a general installation estimate. Tear-off of an existing roof can add to your total cost and isn’t included by default — factor in an additional cost if your project requires removing an existing layer.
It provides a reliable planning estimate based on typical material and labor pricing, though your final quote may vary based on roof complexity, region, and contractor.
This tool gives a ballpark estimate rather than a binding quote. For a precise, itemized estimate, use RoofSnap to measure your roof and generate a detailed proposal.
