How Much Does a Roof Replacement Cost in Portland, Oregon in 2026?

Roof replacement is the single largest exterior project most Portland homeowners will undertake, and pricing varies more than people expect. This guide breaks down what an honest 2026 quote should look like in the Portland metro — by material, roof size, pitch, and complexity — so you can spot inflated or sandbagged numbers.

Average roof replacement cost in Portland in 2026

Most full roof replacements in Portland fall between $8,000 and $25,000. A 2,000 sq ft single-story home with architectural asphalt shingles, a clean single tear-off, and no decking repair generally lands around $12,000–$16,000 installed. Pricing has risen roughly 8–12% since 2023 due to material and labor costs.

Cost by roofing material

• Architectural asphalt shingles — $4.50–$7.50 per sq ft installed. The default Portland choice. Algae-resistant granules are worth the small upcharge in our wet climate.
• Standing seam metal — $12–$20 per sq ft installed. Highest upfront cost, 50+ year lifespan, low maintenance.
• Corrugated metal — $8–$14 per sq ft installed. More affordable than standing seam, still long-lasting.
• Cedar shake — $9–$15 per sq ft installed. Beautiful and traditional but moss-prone in Portland; needs treatment.
• Flat roofing (TPO / EPDM) — $7–$12 per sq ft installed. Used on flat or low-slope roofs over additions and modern builds.
• Synthetic / composite (DaVinci, Brava) — $10–$16 per sq ft. Looks like slate or shake without the weight or moss issues.

What actually drives the price up

1. 1.Roof size, measured in squares. One roofing square = 100 sq ft. A typical Portland home is 20–30 squares.
2. 2.Pitch (steepness). Steeper roofs cost more — both labor and safety equipment scale up sharply above 6/12 pitch.
3. 3.Number of tear-off layers. Single tear-off is standard; two layers means roughly $1,000–$2,000 more in dump fees and labor.
4. 4.Decking condition. Soft or rotted sheathing has to be replaced — $80–$120 per sheet plus labor.
5. 5.Complexity. Multiple dormers, hips, valleys, and skylights all add cost. A simple gable roof is the cheapest to replace.
6. 6.Permits. Portland metro permits typically run $200–$600.

How to budget honestly

If you have a 1,800–2,200 sq ft single-story home with a moderate-pitch roof and want architectural shingles, budget $13,000–$17,000. For a larger two-story or a complex roof with multiple planes, plan on $18,000–$28,000. Get three written quotes and make sure each includes tear-off, underlayment, ice and water shield in valleys, ridge venting, and full cleanup — those are the line items people skip to lowball a number.
