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
Specific to 85085
What changes the price on this street
These are the things that differ here from Phoenix as a whole. Everything else on the Phoenix page still applies.
The typical job is underlayment replacement, not new tile
Original builder underlayment in this cohort is at or past end of life while the tile is still serviceable. Quotes should be structured as a lift-and-relay with a stated breakage allowance.
Simple rooflines keep labour predictable
Compared with custom-home neighbourhoods, plane counts here are low and access is good, which narrows the plausible spread between competing quotes.
