What Affects the Cost in NJ?
These are the key factors that will determine your actual project cost in Central NJ.
Roof Size & Pitch
A steep pitch requires safety equipment and more labor. Costs are measured in "squares" (100 sq ft). Most NJ homes run 18–25 squares.
Number of Layers
NJ code allows up to 2 layers of shingles. A second tear-off adds $1,000–$2,500 to the job.
Decking Condition
Rotted or damaged sheathing must be replaced at $75–$100 per sheet. This is found during tear-off.
County & Permit Fees
Middlesex, Monmouth, and Ocean County each have different permit requirements. Permits typically add $300–$700.
Season
Summer and fall are peak season. Winter and early spring often come with discounts of 10–15%.
