Solar R&R (detach and reset) in NJ typically costs $1,500–$4,500 depending on system size, panel type, and inverter. A standard 20-panel system averages $2,500–$3,500. Most solar companies charge $250–$400 per panel when hired separately — Best Crew bundles solar R&R with the roof replacement under one contract, with no separate mobilization fees.
Why Solar Panels Need to Be Removed for a Roof Replacement
When a home with solar panels needs a new roof, the panels must come off first. There's no shortcut. Here's why:
- The roof underlayment, ice & water shield, and shingles must be installed in a continuous layer — panels mounted on top block that work entirely
- Penetrations (lag bolts that anchor the racking system) need to be resealed during installation — they cannot be properly flashed if the panels are in place
- NJ building code requires complete tear-off down to the deck on a replacement — working around panels violates the permit scope
- Any contractor who claims to replace a roof without removing panels is not doing a complete, code-compliant job — and your new roof warranty would be invalid
Most NJ homeowners with solar don't realize this until they're in the process of scheduling a roof replacement. The roofing contractor tells them the panels need to come off — and suddenly they have to find a solar company to coordinate the removal, which adds time, cost, and complexity.
Solar R&R Cost by System Size (NJ 2026)
The cost depends primarily on the number of panels and whether the inverter needs to be disconnected separately. String inverters (one box per system) add minimal cost. Microinverters (one per panel) add more time during reconnection and testing.
| System Size | Typical kW Size | Standard String Inverter | Microinverter System | Includes |
|---|---|---|---|---|
| 10 panels | 3–4 kW | $1,500–$2,200 | $1,800–$2,600 | Disconnect, remove, stack, reinstall, reconnect, test |
| 15 panels | 5–6 kW | $1,900–$2,800 | $2,300–$3,200 | Same as above + racking inspection |
| 20 panels | 7–8 kW | $2,500–$3,500 | $3,000–$4,000 | Most common NJ residential system |
| 30 panels | 10–12 kW | $3,500–$4,800 | $4,200–$5,500 | Same as above + battery/storage isolation if applicable |
| 40 panels | 14–16 kW | $4,500–$6,200 | $5,500–$7,500 | Large systems; multi-array configuration |
Prices reflect licensed disconnection, panel removal, stacking, reinstallation, reconnection, and basic system test. Battery backup systems (Tesla Powerwall, Enphase IQ) may add $500–$1,200 for isolation and reconnection. These are 2026 NJ market estimates — bundling with roof replacement typically reduces total cost vs. hiring separately.
What's Included in a Solar R&R Job
- Utility notification and disconnect coordination
- AC/DC electrical disconnection at the inverter and array level
- Panel removal from racking system (careful handling to prevent micro-crack damage)
- Racking rail removal (if full racking teardown is needed)
- Safe stacking and storage of panels on-site during roofing work
- Inspection of all roof penetrations (lag bolts) during re-install
- Racking reinstallation with new sealant at all penetrations
- Panel reinstallation and torque to manufacturer spec
- Electrical reconnection by licensed electrician
- System power-up and basic output verification
- Documentation for warranty compliance
Why Solar R&R Is Expensive When Hired Separately
When the roofing contractor and the solar company are two different businesses, you pay twice for setup, travel, and coordination — and you take on all the scheduling risk yourself.
Solar company comes out first to remove panels. Roofer schedules their work. Solar company comes back to reinstall. If the roofer runs long, the solar re-install trip gets rescheduled. Each visit has its own mobilization fee. Total coordination time: days to weeks.
One crew handles panel removal, roofing work, and reinstallation on the same day. No coordination gap. One contract. One point of contact. If anything goes wrong, there's no finger-pointing between contractors.
If roof leaks at a penetration point, the roofing contractor says it's the solar company's racking issue. The solar company says it's the roofer's flashing issue. Neither warranty covers you clearly. You're stuck in the middle.
When one contractor handles both the roof and the R&R, every penetration point is their responsibility. No blame game. If a lag bolt leaks three years later, you have one phone call to make.
Best Crew's Approach: One Crew, One Contract, One Day
Best Crew Construction handles solar R&R as part of the roof replacement job — not as a separate engagement. This means:
- One crew handles the entire job start to finish
- Panels come off in the morning before tear-off begins
- Roofing work proceeds on the cleared deck
- Panels go back on after the new roof is dried-in
- Electrical reconnection and system test same day
- One contract, one price — no separate mobilization fees
- All penetrations warranted under the same roofing warranty
Most standard solar roof jobs (20-panel system, 2,000 sq ft home) are completed start to finish in a single day. You wake up with an aging roof and solar panels, and end the day with a new roof and a fully operational solar system.
How the Day Works
Risks of DIY or Using the Wrong Contractor
Solar R&R sounds straightforward — lift panels off, put them back on. In reality, there are several ways it goes wrong:
| Risk | What Happens | Consequence |
|---|---|---|
| Unlicensed electrical work | Non-electrician reconnects the system | NJ code violation; insurance may deny fire claims; inverter warranty voided |
| Improper racking sealant | Lag bolt penetrations not resealed correctly | Roof leak at every penetration point; both warranties disputed |
| Panel micro-cracking | Panels mishandled during removal/transport | Invisible cell damage; output degrades 10–30% over 2 years |
| No permit pulled | Electrical reconnection done without permit | Open permit may surface at home sale; potential fines; insurance issues |
| DIY removal | Homeowner removes panels without disconnecting system | Electrocution risk from back-fed DC voltage (solar produces current even at night) |
Never disconnect or remove solar panels yourself. A solar array produces DC voltage even on cloudy days and without grid connection. The electrical hazard is real. Always use a licensed electrician for the disconnection step.
Solar R&R in NJ — What You Need to Know
- Solar panels must be removed before a roof replacement — there's no way around it
- NJ solar R&R typically costs $1,500–$4,500 depending on system size; a 20-panel system averages $2,500–$3,500
- Microinverter systems cost $300–$700 more to R&R than string inverter systems
- Hiring the roofer and solar company separately creates coordination delays, warranty gaps, and double mobilization fees
- Using one contractor for both the roof and R&R eliminates the blame game if anything goes wrong later
- Electrical disconnection and reconnection must be performed by a licensed electrician — not DIY
- Permits are required for electrical reconnection in most NJ municipalities — always confirm your contractor is pulling them

Frequently Asked Questions
Solar R&R (detach and reset) in NJ typically costs $1,500–$4,500 depending on system size, panel type, and inverter. A standard 20-panel system averages $2,500–$3,500. Most solar companies charge $250–$400 per panel when hired separately. When bundled with a roof replacement through a contractor that handles both, there are no separate mobilization fees.
No. Solar panels must be removed before a roof replacement can begin. The underlayment, ice & water shield, and shingles must be installed in a continuous layer — panels mounted on top block that work entirely. NJ building code also requires complete tear-off on a replacement. Any contractor claiming to roof without removing panels is not doing a complete, code-compliant job — your new roof warranty would not be valid.
It can, if done incorrectly. Most solar panel manufacturers require that removal and reinstallation be performed by a licensed electrician or certified solar contractor. If an unqualified person performs the R&R, the panel warranty (typically 25 years) and inverter warranty may be voided. Best Crew uses licensed electricians for all disconnection and reconnection work, and documents the process for warranty compliance.
Panel removal takes 2–4 hours for a standard 20-panel system. Reinstallation after roofing work takes another 3–5 hours. When bundled with a roof replacement as a single-day job, the full sequence (removal, roof work, reinstall, electrical reconnection, and test) typically takes one full day for systems up to 30 panels on a 2,000–2,500 sq ft home.
The best approach is to use a contractor who handles both — one crew, one contract, one day. If you hire separately, you face scheduling delays, two mobilization fees, and warranty risk from disputes between contractors if something goes wrong later. Best Crew handles both the roofing and the solar R&R under one contract, removing that coordination risk entirely.
Yes. A permit is required for the electrical reconnection work in most NJ municipalities. Some towns also require a mechanical permit for the racking system. Your contractor should pull all required permits before work begins. Unpermitted electrical work creates liability — your homeowner's insurance may not cover fire or damage caused by unpermitted electrical installations, and open permits can surface as issues during a home sale.
