Three stations on one roof: tear-off, laying, ridge.
Federal occupational wage data puts 135,490 roofers in the United States at a mean of $27.95 an hour, or $58,140 a year. The median — the middle roofer, which is the more useful figure — is $26.65 an hour, $55,440 a year.
| Percentile | Hourly | Annual |
|---|---|---|
| 10th | $18.01 | $37,460 |
| 25th | $22.24 | $46,260 |
| 50th (median) | $26.65 | $55,440 |
| 75th | $31.44 | $65,390 |
| 90th | $39.29 | $81,720 |
The spread from the tenth to the ninetieth percentile is more than double — $37,460 to $81,720. Very little of that is skill in the abstract; most of it is geography, union coverage and whether the work is year-round.
| State | Annual mean |
|---|---|
| Illinois | $77,650 |
| New Jersey | $74,380 |
| Massachusetts | $72,990 |
| Minnesota | $72,920 |
| New York | $69,350 |
| Washington | $68,870 |
| Alaska | $68,450 |
| California | $67,420 |
| Michigan | $61,450 |
| Hawaii | $61,430 |
| Florida | $48,870 |
| Texas | $47,200 |
The top of that table is roughly $30,450 above the bottom. Two forces do most of it. Cold-climate states have a short season, so the day rate has to carry more of the year — and they are also where union residential and commercial work is concentrated. Warm states have year-round work, a larger labour pool and a lower hourly figure that can still add up to comparable annual earnings.

Very few residential roofers are paid a straight hourly wage. The common structures are piece rate — so much per square laid, which rewards speed and is why supervision matters; day rate for tear-off and clean-up, where the work does not divide neatly by square; and a foreman on salary with a crew on piece. Commercial and union work is more often hourly with a schedule.
Piece rate is not the same as cheap
A crew on piece rate has a direct financial incentive to lay fast, and a good contractor prices supervision into that. When a bid is far below its neighbours, the saving is usually supervision rather than wage — and supervision is what catches a nail line drifting high.

The wage is not the cost. Add payroll taxes, workers’ compensation at roofing’s rate — among the highest of any trade — general liability, vehicles, fuel, tools and the days weather takes away, and a loaded crew hour is roughly two to two and a half times the base wage before any overhead or margin. That is why labour is 40–60% of an installed price rather than the smaller share a bare wage would suggest. The production rates behind it are on the labour-per-square guide, and the effect on a whole job is on the cost calculator.
