How much does a roof replacement cost in New Jersey?
Most New Jersey homeowners pay between $7.00 and $12.00 per square foot for a professionally installed asphalt shingle roof in 2026. For a typical 1,700 sq ft roof, that works out to roughly $11,900 – $20,400 including tear-off, materials, and labor. Metal roofing systems cost more per square foot but last significantly longer. Flat roofing system prices vary depending on the kind of material and whether it’s a coating or a full TPO/EPDM replacement.

How does the calculator work?
Enter your address and our calculator locates your home on high-resolution satellite imagery, measures the surface area of your roof (including pitch), and applies current New Jersey pricing for your selected material. It's the same measurement approach professional estimators use — without anyone needing to climb on your roof.
Why do we ask about your timeline and roof condition?
Pricing and crew availability vary across New Jersey, and urgent jobs like active leaks are scheduled differently than planned replacements. A few quick questions mean your estimate — and the follow-up quote — actually match your situation.
