Roof replacement: what moves the price in Kahului
Permit
Roof replacement permits run $100-$500 depending on the location.
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.
Who does the work: Kahului trade wages
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 Kahului the blend is 1.20.
Roofers (47-2181), 85% of the weighting: a median of $29.52 an hour, 11% above the US median of $26.65. The middle half of them earn between $22.97 and $37.64 an hour. About 100 work in the metro. That is 13.6 per 10,000 jobs, compared with 8.7 nationally, which suggests plenty of local crews to bid.
For construction laborers (47-2061, weighted 15%) the local median is $38.35 an hour, which is 69% above the national $22.66. The middle half of them earn between $28.72 and $47.03 an hour. BLS counts 630 of them working in the area, 85.4 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
A quick sensitivity check: moving the lead trade (roofers) from the median to the 75th percentile wage adds about $1,500 to the midpoint estimate; the 25th percentile takes off about $1,200. That is a swing of roughly 11.0% to 13.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Kahului-Wailuku has 73,750 jobs in total (BLS, May 2025), ranking 250th by size among the 300 metros on this site.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Roofers (47-2181) | 85% | $22.97 | $29.52 | $37.64 | $26.65 | 1.11 | metro |
