What drives the cost
Roof pitch and stories — steep or high roofs add labor and safety costs
Tear-off of existing layers versus overlay
Decking repairs discovered after tear-off (common surprise cost)
Material grade: 3-tab vs architectural vs metal is a 2–3× spread
Repair or replace?
If the roof is under ~15 years old and damage is localized (a few missing shingles, one flashing leak), a $300–$1,500 repair usually beats replacement. Replace when shingles are curling or shedding granules across large areas, or when leaks recur in different spots — patching a failing roof is paying twice.

Methodology & sources
National range cross-checked against multiple published 2026 cost guides (Angi, HomeGuide, Homewyse, This Old House, Fixr and trade publications) in July 2026.
State adjustment uses an editorial labor-cost index (0.85–1.35 vs national average) — a simplification of real regional variation.
Quality tiers apply published multipliers for material/type differences (3-tab asphalt shingles / Architectural asphalt shingles / Standing-seam metal).
Ranges exclude financing, unusual site conditions, and code-upgrade surprises.
