Not a contractor. Lead referral platform covering Portland's 10 deepest cost markets.
Estimate your replacement cost with line-item breakdown. Uses ZIP routing to apply neighborhood-specific cost drivers, deck repair allowances, and permit fees. Built on the same 10-market PDX cost intelligence as our market pages.
Identify permit class, design review status, fee range, and special requirements for your Portland address before you sign a contract. Knowing this saves 4–8 weeks of timeline surprises in historic districts.
Compare 25/50-year ownership cost for asphalt vs. metal vs. cedar including maintenance cycles, moss treatment, and end-of-life replacement. Resolves the metal vs. asphalt question with math.
1–5 wind exposure rating for your Portland address based on Gorge corridor proximity, ridge-line exposure, and historical major-event data. Recommends material wind rating spec.
Should you replace before selling? Estimates resale recovery using PDX-specific recovery percentages and accounts for buyer-inspection contingency dynamics that hit Portland harder than most markets.
Generic roofing calculators apply national averages to a Portland property. That misses the variables that move PDX quotes most: skip-sheathed deck overlay on pre-1925 stock ($2,500–$5,000), Portland BDS ventilation enforcement ($400–$1,200), historic district design review timeline (4–6 weeks), East Wind corridor specification ($200–$500), and the 18–22 year asphalt life that PDX moss compresses from the manufacturer-advertised 25–30.
Our calculators pull from the same 10-market PDX cost intelligence as the rest of our site. The cost calculator routes your ZIP to the closest kept market and applies that market's specific cost drivers and permit fee structure. The permit lookup pulls the actual BDS / Washington County / Clackamas County permit requirements for your area, including design review triggers. The wind risk score uses neighborhood-specific exposure data with material spec recommendations matched to local conditions.
All five tools are free, no sign-up, no data harvesting. They're free because the same intelligence powers our paid contractor matching service — better tools mean better matches.
