Where the Napa price comes from
We price the labor side from BLS wage data for 2 trades: roofers at 85%, construction laborers at 15%. Weighted together, Napa wages are 1.17 times the national level. Labor makes up about 64% of the midpoint estimate (61% at national prices). BLS does not publish this trade for the metro, so we used the California statewide median.
Materials are scaled with BEA's regional price parity for goods. Napa is at 105.2 against 100 for the US, so a materials line of $3,300 nationally becomes $3,450 here (midpoint, 2,000 sq ft of roof). Permits follow the all-items index of 112.6: $110 to $560.
Data note: 85% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Napa. The wage table below marks each row.

Napa weather and the roof replacement calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Napa State Hospital (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
Weather is not a serious constraint for exterior installation in Napa: no month in the averages is cold enough (an average daytime high under 45°F) or hot enough (an average daytime high of 90°F or more) to rule it out, so the workable window is all year.
Napa gets about 27 inches of precipitation in a normal year. The wettest months are January, February and December (5.5 inches in December). The station averages about 33 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.

What local crews earn in Napa
The labor line is built from BLS wage data, one trade at a time. This job draws on 2 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Napa the blend is 1.17.
Roofers (47-2181) carry 85% of the labor weighting. BLS does not publish this trade for the Napa metro, so we used the California statewide median: $30.58 an hour against $26.65 for the US. The middle half of them earn between $28.57 and $36.27 an hour.
For construction laborers (47-2061, weighted 15%) the local median is $28.75 an hour, which is 27% above the national $22.66. The middle half of them earn between $23.80 and $36.35 an hour. BLS counts 540 of them working in the area, 69.4 for every 10,000 jobs (US: 70.5), so the local bench is about average.
A quick sensitivity check: moving the lead trade (roofers) from the median to the 75th percentile wage adds about $1,050 to the midpoint estimate; the 25th percentile takes off about $370. That is a swing of roughly 3.5% to 9.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Napa has 77,860 jobs in total (BLS, May 2025), ranking 242nd by size among the 300 metros on this site.

Why two Napa quotes can differ
Shingle type
3-tab asphalt is $3-$5 per sq ft installed; architectural is $4-$6 (HomeGuide). Metal, tile and slate are separate projects with much higher ranges.
Roof area, not floor area
Pitch and complexity mean roof surface is larger than the house's footprint. A 1,500 sq ft ranch can have 1,800-2,200 sq ft of roof.
Tear-off and layers
Removing a second layer or rotted decking adds cost, and the contractor can only see decking damage after tear-off.
Pick a size, pick a tier: roof replacement pricing in Napa
The cited range is split into basic, standard and premium bands, then scaled to Napa. Bands overlap, because plenty of standard jobs cost as much as a light premium one. Sizes run from small (1,200 sq ft of roof) to very large (3,600 sq ft of roof).
Basic
$6,900 to $9,750
3-tab shingles, single layer, simple roof
Standard
