If you’re a homeowner in New Jersey wondering what a roof replacement is going to cost you, you’re not alone — it’s one of the first questions we get every single day at Herts Roofing. The honest answer: it depends, but we can give you real numbers so you’re not going in blind.
Average Roof Replacement Cost in NJ
For a typical single-family home in New Jersey, a full roof replacement runs between $8,000 and $22,000. Most homeowners land somewhere in the $10,000 to $16,000 range. Here’s a quick breakdown by roof size:
- Small roof (under 1,500 sq ft): $7,000 – $11,000
- Medium roof (1,500 – 2,500 sq ft): $10,000 – $16,000
- Large roof (2,500+ sq ft): $15,000 – $25,000+
What Affects the Price?
These are the biggest factors that move the number up or down:
1. Roof Size and Pitch
Contractors price roofing by the “square” (100 square feet). A steeper pitch means more labor and safety equipment — expect to pay 20–30% more for a high-pitch roof vs. a low-slope one.
2. Material Choice
- 3-tab asphalt shingles: $4–$6 per sq ft installed — least expensive, shorter lifespan
- Architectural shingles: $5–$9 per sq ft — most popular in NJ, 30-year lifespan
- Metal roofing: $10–$18 per sq ft — premium, 50+ year lifespan
- Flat roof (TPO/EPDM): $5–$12 per sq ft depending on system
3. Number of Layers to Remove
If your existing roof has two or more layers of shingles, tear-off costs increase. NJ building code generally limits roofs to two layers — if you’re at two, everything has to come off.
4. Decking Condition
Rotted or damaged plywood sheathing adds cost. We can’t know how much until we’re up there — but we always document it and show you before we add anything to the bill.
5. Permits
Roof replacements in NJ require permits in most municipalities. We pull them for you — it’s built into our pricing. Never hire a contractor who skips permits.
Does Insurance Cover Roof Replacement in NJ?
If your roof was damaged by a storm, hail, or wind, your homeowner’s insurance may cover most or all of the replacement cost. We work with insurance claims regularly and can help document the damage properly. Learn more about storm damage claims here.
