What permits and inspections does Gresham require for a new roof?

What should a roofing quote in Gresham include?
A complete quote in Gresham should include tear-off, underlayment, flashing, drip edge, starter strip, ridge cap, decking inspection, disposal/cleanup, and the permit. Mixed-climate quotes should still call out ice and water shield in the lowest-temperature months and ridge ventilation for summer attic heat. If your Gresham quote leaves any of these unlisted, ask the contractor to itemize the omission before signing — that's where change-order surprises come from.
My home in Gresham is older. Does that affect the cost?
Often yes. Homes in Gresham average around 38 years old. Older roofs may need additional decking repair, updated ventilation, or code-required upgrades that add to the base replacement cost.
