Roof replacement cost calculator
Three questions gets you a range. After that, every assumption is yours to change — and the breakdown shows exactly what each change does to the price.

Bureau of Labor Statistics wage release for May 2025, occupation 47-2181 (roofers), across 15 metro areas.
2 of 24 material rows come from observed prices; the rest are modelled.
Metro-level pricing in 15 markets and written local guidance for 17 cities. Anywhere else falls back to national figures, and the confidence score says so.
Pitch multipliers, roof area and material quantities are arithmetic, not estimates.
About 65% of a typical re-roof is still priced from modelled rows, so every estimate is capped at a confidence of 60 until that changes. We would rather show you that than a confident-looking number we cannot stand behind. Sources and licences
Step 1 of 3
Where is the property?
Labour rates, permit fees and disposal costs are local. This is the single biggest driver of what your roof costs.
We start with location because labour, permits and disposal are local, and together they are most of what makes the same roof cost different amounts in different cities.
Your estimate will appear here
Three questions is enough for a first number. After that you can refine any assumption and watch the price move, so you can see exactly what is driving it.
