Standard architectural asphalt shingles — the most common roof type in New Jersey — are designed to last 25-30 years. If your roof is 15 years old or older, there is a high probability it will need replacement before your solar panels reach end-of-life (typically 25-30 years). When that happens, your solar installer must remove every panel, disconnect the wiring, wait for the roofers to finish, then reinstall and recommission the system.
That remove-and-reinstall (R&R) process costs $2,000-$6,000 in New Jersey — a pure avoidable expense. If you bundle the roof replacement with your original solar installation, you pay the roofing cost once, at the most convenient time.
Here are typical New Jersey costs for both components — and the math on why bundling beats waiting.
| 3-tab shingles (basic) | $6,000-$10,000 |
| Architectural shingles (standard) | $8,000-$15,000 |
| Impact-resistant (coastal) | $12,000-$18,000 |
| Standing seam metal | $20,000-$35,000 |
Typical 2,000 sq ft NJ home. North NJ labor costs ~15% higher than South NJ.
| Small system (6-8 kW) | $18,000-$22,000 |
| Medium system (8-12 kW) | $22,000-$30,000 |
| Large system (12-16 kW) | $30,000-$40,000 |
| R&R cost (future) | $2,000-$6,000 |
No federal 25D ITC in 2026. NJ ADI/SREC-II still applies.
Bundling saves approximately $6,000 in this example — before accounting for inflation on future roofing costs.
New Jersey's climate and geography create specific roofing requirements that affect solar compatibility. Here's what NJ homeowners need to know.
New Jersey experiences nor'easters that can bring sustained 50-70 mph winds with gusts over 80 mph. Your roof and solar mounting system must be engineered for this. When replacing a roof for solar, specify Class 4 impact-resistant shingles (the highest ANSI/FM 4473 rating). These resist hail damage and qualify for insurance discounts from many NJ carriers. Your solar installer will specify the correct wind load calculations for panel mounting based on your location.
Shore communities from Sandy Hook to Cape May fall within ASCE 7 high-wind zones. Homes within one mile of the coast may require enhanced hurricane strapping, heavier gauge mounting rails, and closer rafter spacing for solar attachment. This adds $500-$2,000 to installation cost but is required by local building code. Ask your installer specifically whether your address requires a coastal wind load engineering review.
Architectural (dimensional) shingles are the standard choice for NJ solar homes. They are thicker than 3-tab, more wind-resistant (rated to 110-130 mph), carry 30-year warranties, and provide a stable surface for solar mounting hardware. GAF TimberLine HDZ and CertainTeed Landmark are the two dominant brands in NJ — both are carried by most roofing contractors and are solar-compatible. If your installer is GAF-certified, ask about the GAF EnergyGuard underlayment for additional thermal efficiency.
Standing seam metal roofing is the premium choice when bundling with solar — and the math is stronger than most NJ homeowners realize.
The good news: you may be able to finance both in a single loan. Here's how NJ homeowners do it.
Several solar-specific lenders (Mosaic, Goodleap, Service Finance) allow roofing costs to be included in the solar loan if the roof work is necessary to enable or protect the solar installation. This is typically allowed for the full roof replacement cost — not just the section under the panels.
NJ homeowners with significant equity can use a HELOC or home equity loan to finance both roof and solar. NJ has some of the highest home values in the country, and the solar addition itself increases home equity (Zillow research shows solar adds ~4.1% to home value). HELOCs currently run 7-9% APR; fixed home equity loans run 6-8%.
The NJ Clean Energy Program does not currently offer a direct roofing rebate. However, the NJ Home Performance with ENERGY STAR program and NJM's resilient home programs provide partial funding for weatherization improvements that often accompany roofing projects. PSE&G's on-bill repayment program (up to $75,000) covers solar but not roofing directly.
Bundling solar and roofing changes your insurance profile — both the coverage you need and the cost. NJ coastal homeowners face additional complexity.
When you complete a roof replacement and solar installation, contact your homeowners insurance company immediately. You will need to update:
If your home is in a shore community (Ocean County, Monmouth County, Atlantic County, Cape May County), review your policy's wind deductible. Many NJ coastal policies carry a separate hurricane or wind deductible of 2-5% of dwelling coverage — not a flat dollar amount.
NJ's largest homeowners insurer explicitly covers solar panels as attached structures. Known for strong storm claims handling. Offers new roof discounts.
Covers solar under dwelling coverage. May require rider for systems over $20,000. Ask specifically about the Fortified Home program discount for Class 4 roofs.
Both cover solar as part of dwelling. Coastal NJ policies from these carriers often have higher wind deductibles — review carefully.
Last-resort insurer for high-risk coastal homes. Covers solar but at replacement cost value. Premiums are significantly higher — private market is always preferred.
If your roof is 15 years old or older, yes — replace it first. Standard architectural shingles last 25-30 years. Installing solar on an aging roof means you will likely need to pay $2,000-$6,000 to remove and reinstall your panels when the roof fails. Bundling solar + roof is almost always cheaper overall.
Removing and reinstalling solar panels when a roof needs replacement typically costs $2,000-$6,000 in New Jersey, depending on system size and complexity. This is a pure add-on cost — you are paying to undo and redo work that could have been avoided by replacing the roof during the original installation.
A typical roof replacement in New Jersey costs $8,000-$15,000 for a 2,000 sq ft home using architectural shingles. Costs are higher in North Jersey (labor costs) and lower in South Jersey. Metal roofing runs $20,000-$30,000 but lasts 50+ years and is excellent for solar mounting.
Yes, in many cases. Some solar lenders allow roofing costs to be rolled into a solar loan if the roof work is directly connected to enabling the solar installation. Mosaic and Goodleap both allow this for energy-related improvements. Confirm with your lender — not all programs allow it, and the roof portion may have different terms.
GAF and CertainTeed are the dominant brands in NJ and both produce solar-compatible architectural shingles. GAF TimberLine HDZ and CertainTeed Landmark shingles are the most common. Both carry strong warranties (lifetime limited). Metal standing seam roofing from manufacturers like McElroy or Fabral is the premium choice for solar due to clamp-based mounting (no penetrations).
Yes, for two reasons. First, standing seam metal roofs use clamp-based solar mounting that requires no roof penetrations — eliminating leak risk entirely. Second, metal roofs last 50+ years, so you will never need to remove solar panels for a roof replacement. The higher upfront cost ($20,000-$30,000 vs $8,000-$15,000 for shingles) is often justified for homeowners planning 25+ year solar ownership.
Shore communities (Toms River, Long Branch, Atlantic City area) should use impact-resistant shingles rated for high-wind zones (Class 4 impact resistance) and solar panels rated for marine environments. Wind uplift in coastal NJ can exceed 130 mph during nor'easters. Coastal homeowners should also check their insurance wind deductible before bundling — shore properties often have 2-5% wind deductibles.
Not necessarily — most solar lenders require only that the roof be in structurally sound condition and have sufficient remaining life. Some lenders require a roof with at least 10 years of useful life. If your roof inspection shows it will need replacement within 5-7 years, most installers will recommend doing it now to avoid the future remove-and-reinstall cost.
