Notes
- Where the number comes from. The national price for a full asphalt shingle roof replacement is $560 per square — installed asphalt shingle pricing published for 2026, $3.50–$10.00 per ft² of roof. Labor is about 60% of that. Roofers near Helena, MT average $57,010 a year against a U.S. mean of $58,140 — a factor of 0.981 — so the labor half is scaled by that and the material half is not. Source: BLS does not publish a metro figure for roofers near Helena, MT, so this is the Montana state average, SOC 47-2181.
- This one falls back to a wider average. BLS did not publish a metro-level wage for this trade near Helena, MT, so the figure above is a state average. It is still the right order of magnitude, but a local bid carries more weight here than it would in a large metro where the survey has more responses.
- Ice barrier required. Helena designs to -12°F, so IRC R905.1.2 ice barrier applies — two courses of membrane at the eaves, typically $60–$120 per square added.
- What is in the price: tear-off of one layer, synthetic underlayment, architectural shingles, starter, ridge cap, drip edge, nails, disposal and labor.
- What is not: decking replacement, chimney or skylight flashing rebuilds, structural repair, and permits. These are the lines that turn a $16,604 quote into a $20,755 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.

About 60% of this job is labor — $9,962 of the $16,604 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.
Roofers near Helena average $57,010 a year, against a U.S. mean of $58,140. That is a factor of 0.981, so the labor half is scaled by it and the material half is not.

This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.
If a bid lands outside $11,267 – $26,685, that is not automatically wrong — but it is the question worth asking out loud.
