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 90042
What changes the price on this street
These are the things that differ here from Los Angeles as a whole. Everything else on the Los Angeles page still applies.
Skip sheathing usually means a full re-deck
Homes originally roofed in wood shake have spaced boards rather than solid decking. Modern roofing needs a solid deck, so a full sheet of new sheathing is often unavoidable and should be quoted explicitly.
Hillside access adds real hours
Narrow streets, no driveway staging and long carries change the labour line significantly. A contractor who has not visited the property cannot price this.
