Why 3-tab asphalt × San Francisco produces this band

A 3-tab asphalt scope for a roof replacement in San Francisco combines two price levers: scope and metro labor rates. 3-tab asphalt is the lowest-cost roof — flat tab pattern, 15-20 year warranty, lightest on the structure. Used on budget-conscious jobs and rental property. Against the national median remodel labor rate, San Francisco runs 55% above the national median — so the 3-tab asphalt band comes in 45% below the mid-range, then scales 55% above the national median on top of that. Permit timelines for residential work in San Francisco typically run 10-26 weeks, which is the window you plan your design and decision sequence against. This page gives you the actual 2026 San Francisco bands for this exact combination, plus the three cost drivers Baily asks about first when scoping the project live.
