Quick answer
In 2026, most asphalt-shingle roof replacements in Oregon run roughly $10,000–$25,000 with a full tear-off — about $475–$775 per square of architectural shingles, depending on pitch. Metal typically runs about 1.9× the asphalt figure. Your roof's square footage, steepness, layers, and material set where you land in that range. Every number here is an honest estimate, not a quote — the only real number is a written estimate for your roof.
Pricing a roof in Oregon is genuinely confusing. Every contractor quotes it a little differently, and most "average roof cost" articles online are written for a national audience that roofs over old shingles in dry climates — neither of which describes the wet side of the Cascades. Here's the straight version from a family crew that reroofs homes across Douglas County in every season, including the rain.
One promise before the numbers: everything below is an estimate, not a quote. Roofs vary far too much for a single honest figure. Want a real one? Our instant roof estimate sizes your roof from satellite building data and prices it by pitch in about 30 seconds, and a written on-site estimate is always free.
2026 Oregon price ranges
For a typical single-family home, here is what we see across the state this year:
- Architectural asphalt replacement: most jobs land between $10,000 and $25,000, tear-off included. A small 15–18 square ranch can dip below $10,000; a 30+ square home with steep, complicated planes can pass $25,000.
- Per square (100 sq ft): roughly $475–$775 per square installed for architectural asphalt, covering tear-off, underlayment, flashing, and shingles. The low end reflects walkable roofs; the high end reflects steep, hand-nailed, harness-required work.
- Metal roofing: plan on about 1.9× the asphalt number for standing-seam. It lasts 40–70 years and sheds Oregon's moss and needle litter far better, so the lifetime math is closer than the sticker suggests — we break it down in our metal roof cost guide and metal vs. asphalt comparison.
- Tile and specialty: tile and designer profiles can run 2× or more over asphalt once you add framing and labor.
If a bid lands dramatically below these ranges, pause. Someone is trimming something you can't see yet — underlayment, flashing, permit, or insurance — and the savings tend to reappear in year six.
Why Oregon's climate changes the math
Oregon isn't one climate, and that shows up in roofing cost. West of the Cascades — Portland, Salem, Eugene, and down through the Umpqua Valley where we work — homes take 30–45+ inches of rain a year, most of it between October and May, followed by hot, bone-dry summers. That wet-dry whiplash ages asphalt faster than the national average, so wet-side homeowners lean toward better underlayment, ice-and-water shield in the valleys, and algae-resistant architectural shingles. Those choices cost a little more up front and pay for themselves in years of extra roof life.
East of the Cascades — Bend, Redmond, Klamath Falls — the story flips to snow load, freeze-thaw, and intense UV, which puts a premium on ventilation and ice protection instead. Either way, the biggest cost driver isn't the region; it's your specific roof.
What actually moves your number
| Factor | Effect on price |
|---|---|
| Roof size | The biggest lever. Roofing is sold per square, so a 28-square roof simply costs more than an 18-square one across materials, labor, and disposal. |
| Pitch | A 3/12–4/12 roof might price near $475/square; a steep 7/12–8/12 needing harnesses and staging climbs toward $775/square. 9/12 and up is custom-quoted. |
| Tear-off layers | Two or three old layers doubles or triples tear-off labor and dump fees. Wet-side Oregon almost always requires a full tear-off, no overlays. |
| Deck repair | Rot and delaminated sheathing get replaced by the sheet once the roof is open. Honest bids state a per-sheet price up front. |
| Complexity | Valleys, dormers, skylights, and chimneys mean cutting and flashing. A cut-up roof costs more per square than a simple gable of the same size. |
| Material tier | 3-tab vs. architectural vs. metal vs. tile. Architectural is the wet-Oregon sweet spot — better wind ratings and roughly 10 more years than 3-tab. |

The tear-off rule that raises (and protects) your cost
In much of the country, roofers nail a second layer over the first and skip tear-off. On the wet side of Oregon that's usually off the table — Douglas County and many neighboring jurisdictions do not allow shingle-over-shingle overlays, and reroofs over 100 square feet generally require a permit. That makes a local job cost more than a national overlay average, and it's worth it: overlays trap heat, hide rot, add dead weight, and turn the next reroof into a double tear-off. A full tear-off means your deck actually gets inspected and repaired. Our Douglas County permit guide covers the specifics.
How to compare Oregon roofing bids
Three bids on the same roof can differ by thousands and all be "fair" — they're pricing different jobs. Before you compare totals, make every bidder put these in writing:
- Exact scope. Full tear-off? How many layers assumed? Permit pulled by the contractor?
- The shingle, by name. Manufacturer and product line, not "30-year architectural."
- Underlayment. Synthetic or felt, plus ice-and-water membrane in valleys and at penetrations. Our ice-and-water shield explainer shows why this matters here.
- Flashing plan. New step flashing, kick-outs, and pipe boots — reused flashing is a leading cause of early leaks.
- Deck repair pricing. A stated per-sheet price agreed before tear-off.
- License verification. Look up every CCB number at search.ccb.state.or.us — two minutes for license, bond, insurance, and complaints. Our CCB verification guide walks through it. (We're CCB #255729 — check us, please.)
Where you can honestly save
Not every aging roof needs replacing this year. A targeted roof repair plus maintenance can buy some roofs real time — and our Home Care Membership (from $49/month) stretches roof life with annual inspections and 10% off repairs. When we look at your roof we'll tell you which situation you're in, even when the honest answer earns us less. When replacement is the right call, our roof replacement team builds it to outlast the weather.
Quick answers
What's the average roof cost in Oregon right now?
Most asphalt replacements run $10,000–$25,000 with tear-off, about $475–$775 per square. Metal runs roughly 1.9× that. Size, pitch, and condition decide where you land.
Can I roof over my old shingles?
On the wet side of Oregon, usually no — Douglas County and many jurisdictions require full tear-off, no overlays, with a permit over 100 sq ft.
