About this tool
What the Roofing Labour Cost Estimator does
Roof replacement quotes combine labour per square, tear-off of old layers, a surcharge for steep or complex roofs, materials, disposal and permits. This estimator builds the quote line by line so homeowners can compare bids and contractors can price consistently.
It also works as a roofing labor cost estimator or a roof replacement cost calculator.
Formula
- Labour = squares × rate × (1 + surcharge)
- Tear-off = squares × layers × rate
- Price = (labour + tear-off + materials + disposal + permits) × (1 + markup)

How to read the result
Ask every roofer to quote the same scope: underlayment, flashing, ventilation and decking repairs often explain price differences.
Hidden rotten decking is a common extra; agree a per-sheet replacement price in advance.
Quantities are estimates. Check product data sheets and local codes, and confirm with your supplier before ordering.
