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 92109
What changes the price on this street
These are the things that differ here from San Diego as a whole. Everything else on the San Diego page still applies.
Corrosion resistance is a specification issue, not an upsell
Within this distance of the ocean, fastener, flashing and edge-metal metallurgy materially affects service life. A cheaper quote using standard galvanised components is not equivalent.
Low-slope membrane dominates
Much of the stock has flat or near-flat roofs requiring membrane systems, which are priced per square foot with detailing costs that scale with penetrations and parapets rather than with area.
