Moss and algae Common
Wet winters and shade from Douglas firs keep shingles damp. Moss lifts the tabs and holds water against the deck. Treatment buys time; thick moss on a roof past 20 years usually means replacement is close.

2026 price guide
Portland roof replacement cost by material
Roofers price by the square: 100 sq ft of roof surface. Ranges below are installed prices with one layer torn off, for a 25-square roof, which is about what a 2,000 sq ft single-story home has.
| Material | Installed, per sq ft | 25-square roof | Typical life here |
|---|---|---|---|
| Architectural asphalt | $6.50–$9.50 | $16,250–$23,750 | 20–25 years |
| Designer asphalt | $8.50–$12.00 | $21,250–$30,000 | 25–30 years |
| Standing-seam metal | $13.00–$20.00 | $32,500–$50,000 | 40–60 years |
| Cedar shake | $11.00–$17.00 | $27,500–$42,500 | 20–30 years with moss care |
| Flat / low-slope (TPO, torch-down) | $7.50–$12.00 | $18,750–$30,000 | 15–25 years |
How the estimator does the math:
home sq ft ÷ stories × 1.08 (eaves) × pitch factor = roof area
roof area × installed rate × height & steepness adjustment = your range
Pitch factors: 3/12 ≈ 1.06 · 6/12 ≈ 1.15 · 10/12 ≈ 1.35
What fails on Portland roofs
Roughly three feet of rain a year finds every weak spot
Wind and ice storms Insurance
Events like the January 2024 ice storm strip shingles and drop limbs. Sudden storm damage may be covered by homeowners insurance, and a roofer can document it for your claim.
Flashing, vents and skylights Usually a repair
Most leaks start where the roof meets something: chimneys, skylights, plumbing vents and valleys. These are often fixed for a fraction of a new roof.
Age Replace
Curling edges, bald spots, granules in the gutters and soft spots underfoot mean the shingles are done. Asphalt roofs in this climate rarely make it much past 25 years.

Questions
Before you start
How much does a new roof cost in Portland in 2026?
Most architectural asphalt replacements in the Portland area run about $6.50 to $9.50 per square foot of roof, installed. For a single-story 1,900 sq ft home with a standard 6/12 pitch, that works out to roughly $15,000 to $22,500. Metal and cedar cost more; second stories and steep pitches add to the labor.
Is the estimate a quote?
No. It's a range based on regional cost data and your answers. A licensed roofer gives you the real price after an inspection, which also checks the decking, flashing and ventilation the estimator can't see.
Are you a roofing company?
No. PDX Roof Guys is a free referral service. Independent, licensed roofing contractors inspect, quote, contract for and do the work. We don't perform roofing work or sign roofing contracts.
How is this free?
Roofers in our network pay us for introductions. You never pay us anything, and you're never obligated to hire anyone.
How many roofers will contact me?
One, unless you tick "compare quotes," in which case up to three. Leak requests are routed right away; replacement requests usually hear back within one business day.
When is the best time to replace a roof in Portland?
Tear-offs are easiest to schedule in the dry months, roughly June through September, and good roofers book up by late summer. Fall and winter are fine for inspections, repairs and getting on a spring schedule.
