If you’re a New Jersey homeowner considering a roof replacement, the first question on your mind is probably: What’s this going to cost me?
It’s a fair question — and one that deserves an honest answer, not a bait-and-switch. At EFER Renovations, we believe in transparent pricing. Here’s a straightforward breakdown of what you can expect to pay for a new roof in New Jersey, and what drives those costs.
Average Roof Replacement Cost in NJ (2025)
The typical roof replacement in New Jersey runs between $8,000 and $22,000 for a standard residential home. Here’s a rough breakdown by home size (architectural asphalt shingles):
- 1,000–1,500 sq ft: $7,000 – $11,000
- 1,500–2,000 sq ft: $9,000 – $14,000
- 2,000–2,500 sq ft: $11,000 – $17,000
- 2,500–3,000 sq ft: $14,000 – $20,000
- 3,000+ sq ft: $18,000 – $28,000+
What Factors Drive Roof Replacement Costs in New Jersey?
1. Roof Size and Pitch
Roofing is priced by the “square” — 100 square feet of coverage. A larger roof costs more. Steeper roofs are harder to work on safely and require more time and equipment, which adds to labor costs.
2. Roofing Material
- Standard 3-tab shingles — $5–$7/sq ft installed (less common today)
- Architectural/dimensional shingles — $7–$10/sq ft installed (most popular in NJ)
- Premium designer shingles — $9–$15/sq ft installed
- Metal roofing — $12–$25/sq ft installed (longer lifespan, higher upfront cost)
- Slate or tile — $20–$40/sq ft installed (premium, very long-lasting)
As a licensed NJ contractor, EFER Renovations installs the full GAF Timberline HD and Designer shingle lines, backed by the Golden Pledge Warranty — the strongest warranty GAF offers.
3. Tear-Off and Disposal
If your current roof has two layers of shingles (the maximum allowed in NJ), we’ll need to tear off both before installing the new roof. This adds $500–$1,500 extra depending on roof size. We always recommend a full tear-off rather than installing over existing shingles.
4. Roof Complexity
A simple gable roof costs less than one with multiple valleys, dormers, skylights, or complex flashing details. More complex roofs take longer and require more material.
5. Decking Condition
Once shingles are removed, we inspect the roof deck for rot, water damage, or structural weakness. Replacing damaged decking adds $2–$4 per square foot but is essential. Putting a new roof over a compromised deck is a mistake that always catches up with a homeowner.
6. Permits
In most NJ municipalities, a permit is required for a full roof replacement. Permit costs typically run $100–$400. A reputable contractor handles this for you — if a contractor says you don’t need a permit, that’s a red flag.
Does Homeowners Insurance Cover Roof Replacement in NJ?
Often, yes — if the damage was caused by a covered event like a storm, hail, or wind. Insurance typically does not cover replacement due to age or normal wear and tear.
If you have a storm-damaged roof, your first call should be to a licensed NJ roofing contractor for a free inspection before contacting your insurance company. EFER Renovations has extensive experience working with insurance companies and adjusters throughout Mercer County and Central NJ.
Roof Repair vs. Full Replacement — Which Do You Need?
Not every roofing issue requires a full replacement. Generally speaking:
- Repair makes sense when your roof is under 15 years old, damage is localized, and surrounding shingles are in good condition
- Replacement makes more sense when your roof is 20+ years old, you have widespread damage, multiple leaks, or significant granule loss
When we inspect your roof, we’ll give you a straight answer — not push you toward the most expensive option.
