It's the first question every homeowner asks us — and the one most roofing websites dodge. So here it is, straight: most full roof replacements in Central New Jersey land between $9,000 and $25,000, with a typical single-family home falling in the $12,000–$18,000 range.
Why such a wide range? Because a roof isn't priced like a product — it's priced like a project. Here's exactly what moves the number, so you can read any estimate (ours included) like a pro.
The 5 factors that set your price
1. Size — measured in "squares"
Roofers measure in squares: 1 square = 100 sq ft of roof surface. A typical NJ colonial has 20–30 squares. More surface, more material and labor — this is the single biggest factor.
2. Pitch and complexity
A steep roof or one with many valleys, dormers, and skylights takes longer and requires more safety equipment. Two houses with identical square footage can differ by thousands of dollars on complexity alone.
3. Material
| Material | Typical NJ Range (installed) | Lifespan |
|---|---|---|
| 3-tab asphalt shingles | $4.50–$6.50 / sq ft | 15–20 years |
| Architectural shingles (our standard) | $5.50–$8.50 / sq ft | 25–30+ years, up to 50-yr material warranty |
| Premium designer shingles | $8–$12 / sq ft | 30+ years |
| Standing-seam metal | $10–$16 / sq ft | 40–70 years |
4. What's under the old shingles
This is the honest part most estimates hide: nobody knows the condition of your decking (the plywood under the shingles) until tear-off. Rotted plywood must be replaced — typically $70–$120 per sheet. A quality contractor inspects and documents it with photos instead of quietly covering it up.
5. Layers to remove
Some older NJ homes have two layers of shingles stacked up. Removing extra layers adds labor and disposal cost — but replacing over old layers is a shortcut that voids warranties and hides damage. We always tear off to the decking.
What a real estimate should include
- Complete tear-off and disposal
- Decking inspection (with photo documentation)
- Ice & Water Shield — critical for NJ winters, and required by code at eaves
- Synthetic underlayment, drip edge, flashing, and ridge venting
- The shingle system itself, installed to manufacturer spec so the warranty is valid
- Warranty terms in writing — both material and workmanship
The insurance factor: your roof might cost you only the deductible
If your roof has storm damage — wind-lifted shingles, hail impact, or a tree strike — your homeowners insurance may cover most or all of the replacement. One Dunellen family's approved claim covered $36,900; their out-of-pocket cost was just their deductible. Our part is the Hive Response™ documentation: thorough photos and a detailed damage report that make the claim easier for your insurance company to review and approve.
