Roofers Portland OR: 2026 Roof Replacement Cost Guide
Full roof replacement is a major expense, and roofers across the Portland metro price it differently depending on material tier, roof complexity, and how much of the old structure needs repair once it's torn off. Older homes in Sellwood, Multnomah Village, and St Johns often carry surprises under the shingles -- decades of moss exposure can hide rot that only shows up once tear-off begins. This guide breaks down 2026 roof replacement costs for the Portland metro by material tier, what pushes prices up or down on a specific property, and what to expect from local roofers during the process.

Material tiers and what they cost in 2026
Standard composition (asphalt) shingle remains the most common and most affordable option for a full Portland reroof, typically running $11,000 to $18,500 for a 1,800-2,200 square foot roof.
Architectural/dimensional shingle, now the most popular mid-tier choice among Portland homeowners for its longer lifespan and better wind resistance, runs $14,500 to $23,000 for a similar-sized roof.
Cedar shake, which has a long history in the Pacific Northwest and shows up on older homes in Laurelhurst and Lake Oswego, runs $20,000 to $34,000 and requires more specialized maintenance in a wet climate.
Standing-seam metal roofing, increasingly chosen for its longevity and moss resistance, runs $22,000 to $38,000.
What drives replacement costs up locally
Roof pitch and complexity: steep Craftsman and foursquare roofs common in Irvington and Mount Tabor require more safety equipment and labor time than simple ranch rooflines in Beaverton.
Dry rot discovered during tear-off: older homes with years of untreated moss exposure often need deck repair once the old roofing comes off, which adds cost that's hard to quote precisely upfront.
Number of penetrations: skylights, chimneys, and dormers -- common on older Portland homes -- each add flashing work and cost.
What drives costs down
Simple gable rooflines with minimal penetrations, common in newer Beaverton and outer-suburb construction, cost less per square foot than complex older rooflines.
Scheduling during the peak dry season (July-September) sometimes allows for better pricing since contractors can plan tear-offs more efficiently without weather contingencies eating into labor time.
What to expect from the replacement process
A licensed Portland roofer will pull a permit through Portland Permitting and Development for a full tear-off, schedule around the dry season when possible, and inspect the deck once old roofing is removed before installing new underlayment and ice-and-water shield.
Expect the crew to install ice-and-water shield at eaves and valleys given Portland's rain volume, and ask about ventilation upgrades, since improved attic ventilation reduces moisture buildup that contributes to moss and mold.
Compare bids before you commit
Get at least three written bids specifying material brand, underlayment, ventilation plan, and warranty terms before choosing a roofer, since totals for the same house can vary by thousands of dollars across Portland contractors.

Yes, a full tear-off and replacement requires a permit from Portland Permitting and Development, applied for through the Development Hub PDX portal.
