What’s different about Portland
Portland is Oregon's largest market with a high cost of living, where Cascadia seismic codes and a wet climate drive bracing and moisture-resistant detailing.
- Lighter roofing and seismic fastening are favored in quake zones.
- Algae-resistant shingles are popular where humidity drives streaking.
How the cost is built
Roof cost scales with roof area (measured in 100 sq ft 'squares'), pitch, and material — asphalt shingles are the budget choice, while metal, tile, and slate run two to four times more. Steep or complex rooflines, multiple layers to tear off, and new decking or flashing all add to the total.
