Your roof will be at end of life at sale. PDX buyer's inspectors will flag this; 23% of Portland deals include roofing contingencies that result in $4,000-$12,000 in negotiation credits.
Replacement now recovers ~55% in resale plus avoids inspection-driven price reduction. Net impact $-3,809 understates the case — actual value preservation is higher when accounting for avoided contingency.
National Association of Realtors cost-vs-value reports show 60% national average recovery on roof replacement; Portland metro typically lands 58-72% depending on neighborhood and material. The premium is partly Portland's home-value appreciation, partly the high incidence of roof contingencies in PDX transactions (23% of deals include them, vs 14% national average) — buyers will negotiate hard on aging roofs, so replacement before listing genuinely preserves sale value.
It doesn't — for a typical hold scenario. The recommendation depends on years to sale plus current age. A 15-year-old roof with a 2-year sale horizon has 17 years total at sale (about 70% of life). The calculator typically says "keep it" in this scenario. The "replace before listing" recommendation triggers when ageAtSale exceeds about 80% of expected life, where buyer inspection contingencies become high-probability.
About one in four Portland real estate transactions has a buyer's inspection contingency that flags the roof, requiring either seller credit, replacement before close, or contingency negotiation that delays/kills the deal. Portland's aging housing stock plus aggressive buyer-inspector culture makes this materially more common than national average. Past-end-of-life roofs effectively guarantee contingency triggers — replacement removes the risk entirely.
Roughly, based on home value as a proxy for square footage. For more accurate estimates, use our Roof Cost Calculator which takes actual sq ft + material + pitch + age. The ROI calculator uses approximate cost to keep the input simple — the recommendation logic is robust to ±20% cost variance.
Generally no, unless your home is in a market where metal is heavily favored (West Hills, Lake Oswego high-end). Metal recovers a lower percentage of premium in resale than the recovery calculation assumes — buyers pay for the new roof, not the metal premium specifically. For quick-sale scenarios (1-3 years), architectural asphalt at premium tier (CertainTeed Landmark Pro, GAF Timberline UHDZ) usually delivers better dollar-recovery than metal upgrade.
