This is a budgeting estimate, not a quote. It reconciles two different published data sets for this market — aggregator cost-guide data and real contractor-published ranges — which don't agree with each other, so treat this as the middle of a real range, not a precise number. Your actual price depends on your roof's specific size, pitch, number of penetrations, material, moss/algae-driven deck damage, and access. A binding number comes from a free on-site inspection.
