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 Portland, OR average $66,830 a year against a U.S. mean of $58,140 — a factor of 1.149 — so the labor half is scaled by that and the material half is not.

Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
Ice barrier required. Portland designs to 25°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 $15,256 quote into a $19,069 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.

a full asphalt shingle roof replacement in Portland, OR

$15,256 is the typical number, and three bids on the same scope normally land between $10,352 and $24,518.

That is $1,256 more than the same job priced at the national average.

Why the city changes the number

About 60% of this job is labor — $9,153 of the $15,256 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.

Roofers near Portland average $66,830 a year, against a U.S. mean of $58,140. That is a factor of 1.149, so the labor half is scaled by it and the material half is not.

The lines that turn a quote into an invoice

Ask about each of them before you sign. On a job this size they are the difference between $15,256 and something a quarter higher.

Use it as a bid check, not a quote

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 $10,352 – $24,518, that is not automatically wrong — but it is the question worth asking out loud.
