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 78704
What changes the price on this street
These are the things that differ here from Austin as a whole. Everything else on the Austin page still applies.
Staging space is genuinely scarce
Narrow lots, mature trees and street parking restrictions can mean no dumpster on site, hand-loading, or permit-controlled placement. This adds hours that a satellite quote will not have priced.
Mixed-material roofs need line-item quotes
A modern infill house may combine standing seam, membrane and shingle on one structure. Insist that each system is quoted separately or comparison is impossible.
