32 roofing listings are recorded at Napa, California addresses. None of them has a Google rating matched to it yet, so what follows is contact detail rather than reputation data.
All of them are recorded in Napa County. Roofing permits and inspections are issued locally rather than by the state, so a re-roof in Napa goes through Napa County or the municipality's own building department, whichever holds jurisdiction at the property.

Licensing for roofers working in Napa
California licenses roofing contractors at state level, and the requirement applies to work in Napa. The license is issued by the Contractors State License Board.
A state license is not a substitute for local rules: the job still needs a permit and an inspection through Napa County or the city, and some municipalities require their own contractor registration on top of the state license.
Source: Contractors State License Board. Checked August 2026. Licensing rules change — verify before you sign anything.
What roofing work costs
We have not modeled a cost index for Napa, so there is no Napa figure here. These are the national baseline bands, unadjusted.
National reference bands, not quotes and not local numbers. Local labor rates, permit fees and access all move them.

* The most recent data year is partial. NOAA publishes storm reports on a rolling basis and the final months are still being processed, so a low count in the last year is not evidence of a quiet year. The curated archive behind these counts runs through May 31, 2026; anything later sits in the preliminary block below.
Notable events in the archive
- Feb 19, 2024 -- Thunderstorm Wind (50 kt gust) -- $10 property damage reported
- Aug 16, 2020 -- Thunderstorm Wind (57 kt gust)
- Jun 11, 2017 -- Hail (Pea hail, 0.25 in)
- Apr 27, 2016 -- Tornado (EF0)
Selected by the dataset’s own rule rather than by editorial choice: the largest hail, the peak wind gust, the strongest tornado and the two costliest events by recorded property damage, deduplicated and newest first. Any dollar figure above is NOAA’s recorded estimate for that one event.
What these counts cover. County figures count events NOAA recorded against a county (hail, thunderstorm wind and tornadoes). High wind, winter storms, ice storms, blizzards, heavy snow, hurricanes and tropical storms are recorded against National Weather Service forecast zones rather than counties, so they are reported at state level instead. Counts reflect events that were observed and reported.
“Significant” on this page means an event meeting any one of three tests: hail 1.00 in across or larger, a wind gust of 58 kt or more (the National Weather Service severe thunderstorm criterion), or any tornado. It is a severity definition used by this dataset and is not an official NOAA classification.
The damage figure. $10 is the sum of NOAA’s recorded property-damage estimates across every event in Napa County over the period — a county total, not a figure for any one property, any one building or any one claim. NOAA records these figures as estimates made at the time of reporting. They are not adjusted for inflation, and they are frequently absent or zero — a zero means nothing was recorded, not that nothing was damaged.
Source. Archived figures come from the NOAA National Centers for Environmental Information Storm Events Database, covering 2016 through May 31, 2026. Anything after that date comes from NOAA Storm Prediction Center preliminary storm reports and is labelled preliminary wherever it appears. Both are US Government works in the public domain.
