A new asphalt shingle roof in New Jersey typically costs between $5,800 and $20,000, or roughly $3.50 to $8.50 per square foot depending on shingle grade. Architectural shingles run $450–$700 per "square" (100 sq ft) installed, while premium designer shingles exceed $700 per square. Final pricing depends on roof size, pitch, local labor rates, and whether decking repairs are needed.
