Is this actually worth it?
A roof replacement in 2026 typically returns 60–80% of project cost at resale within the first 5 years, and avoids 2–4× higher emergency-replacement pricing. Owners with a documented roof timeline negotiate ~$3,800 better at sale on average.
Run the ROI mathShould you replace now or wait?
Break-even rule: if annual repair cost exceeds 8% of replacement cost — or the unit is past 75% of expected life — replacement wins. Below that threshold, deferring 18–36 months and funding a sinking fund usually beats panic timing by $1,800–$5,400.
Run the break-even mathHow this impacts your home value
A failing or end-of-life roof typically triggers a $4,000–$12,000 appraiser adjustment in Charleston, SC and shows up in inspection reports as a buyer-negotiation lever. A documented replacement plan inside the last 3 years of life preserves listing price.
