Planning estimate only, not a contractor quote. Built from Home Cost USA modeled national unit costs for roof replacement, and adjusted for job complexity (×1.00). No validated local cost adjustment is applied, so this is a national planning benchmark rather than a local price. Scope assumed: Architectural asphalt shingles with standard underlayment and flashing.

What drives the price
- Size. Most of the cost scales directly with roof area (sq ft), so measuring carefully changes your number more than any other input.
- Material and finish grade. Moving from basic to high-end materials commonly changes the total by two to three times on the same footprint.
- Labor conditions. Access, height, demolition, and existing damage all add crew hours that never show up in a per-unit average.
- Region. Local labor rates, material freight, and permitting practice move totals up or down. Our ranges are a national benchmark today, we will only apply a local adjustment once we have validated local cost data.
- Season and scheduling. Peak demand and emergency timelines carry a premium; flexible timing can save real money.
Questions to ask before you hire
Comparing bids only works when every bid covers the same scope. Ask each contractor the same questions and write the answers down.
- 1Will you tear off the existing layers or install over them, and why?
- 2What underlayment, drip edge, flashing, and ventilation are included?
- 3How will you handle any decking rot you find after tear-off?
- 4Can you send an itemized written estimate that separates labor, materials, and permit fees?
- 5Is your business licensed for this work in my state, and can you share your license and insurance certificates?
- 6Who will be on site day to day, and are they employees or subcontractors?
- 7What is your written warranty on labor, and how long does the material warranty last?
- 8What is your payment schedule, and how much do you require up front?
- 9What would cause the price to change once work starts, and how are change orders approved?
- 10How will you protect the rest of my home, and who handles cleanup and disposal?
