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 in Maine average $53,700 a year against a U.S. mean of $58,140 — a factor of 0.924 — so the labor half is scaled by that and the material half is not.
**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 $13,359 quote into a $16,698 invoice, so ask about each one before signing.
**Why state matters more than people expect.** Materials ship at national prices; crews do not move. Maine sits below the national mean by 7.6%, which lands on 60% of the job and moves the total by $641.
**Use this as a bid check, not a quote.** It prices an average job in an average condition. Steep access, a second story, a tear-off of two layers, or a crew booked out three months all move the real number, and none of them are in a per-unit average.

A 25-square roof in Maine

$13,359 is the typical figure, and bids on the same scope normally land between $9,065 and $21,469.

That is 25 squares at $534 each.

Why this is not the national number

The same job priced at the U.S. average comes to $14,000 — this one is $641 less.

The reason is one number, and it is a published one. Roofers in Maine average $53,700 a year against a U.S. mean of $58,140, from the Bureau of Labor Statistics OEWS release for May 2025, SOC 47-2181. That is roughly $26 an hour of trade pay, a factor of 0.924, or −7.6% against the national mean.

Labor is about 60% of this job. Material is the other 40%, and material does not care what state it is nailed down in — a pallet costs what a pallet costs. So only the labor half is scaled here, and the material half is left at national pricing.

That is the whole model, and it is deliberately simple enough to check: $8,015 of labor, $5,343 of material.

What a square is, and why the estimate hinges on it

A square is 100 ft² of roof, not of floor. A 2,000 ft² single-story house does not have a 20-square roof — a 6/12 pitch adds about 12%, a 10/12 adds 30%, and hips and valleys add waste on top. Measure the roof, or the whole number above is answering a different question.

What is in this price

Tear-off of one existing layer, synthetic underlayment, architectural shingles, starter course, ridge cap, drip edge, nails, disposal, and labor.

What is not

Decking replacement is the big one. It is invisible until the old shingles come off, it is quoted per sheet, and on an older roof it is the line most likely to turn a $13,359 quote into something well past $21,469. Get the per-sheet price in writing before work starts.

Chimney and skylight flashing rebuilds, structural repair, and permits also sit outside this figure.

How to use this against a real bid

Three quotes on identical scope should cluster. One well under $9,065 usually means something was left out of the scope rather than found cheaper — read what is excluded before reading the total. One well over $21,469 is either a harder job than average or a crew that does not want the work and priced accordingly.

The number above prices an average job in average condition. Access, story height, season, and how booked the crew is all move it, and none of those live in a per-unit average.
