Roof Installation Estimator – Reference Data
Roof Area: Many cost guides benchmark “average homes” in the ~1,800–2,500 sq ft roof range (example tables commonly show 2,000–2,500 sq ft roofs).
Material Cost (Installed) per Sq Ft: Typical installed ranges by material include Asphalt $3–$5, Architectural $4–$6, Metal $5–$16, Tile $7–$25, and Slate $10–$30 per sq ft.
Installation Labor per Sq Ft: Labor alone commonly averages $2.00–$3.50 per sq ft for shingles (metal labor often runs higher).
Tear-Off Rate per Sq Ft: Removing old shingles is commonly $1–$3 per sq ft (heavier materials can run higher).
Additional Fees: Common add-ons include permits/inspections, disposal, flashing/vents, and deck repairs. Some guides cite tear-off/disposal averaging about $50 per roofing square (100 sq ft) including dumping fees, but local fees vary.
