You are getting a new roof, and your roofer or installer says the solar panels have to come down first. Before you sign off on who does that work, there is a question worth asking: will removing and reinstalling those panels void the manufacturer warranty you already paid for? Solarnova installs and removes solar panels across New Jersey and Pennsylvania, and warranty protection is one of the most overlooked parts of a re-roof-around-solar job. Solar panel removal is the process of safely disconnecting, unmounting, and storing rooftop modules so a roof, chimney, or other structure underneath can be repaired or replaced. Done the wrong way, it can strip away years of coverage you assumed would always be there.
Why Does Solar Panel Removal Put Your Warranty at Risk?
Most manufacturer warranties require that only a certified or manufacturer-approved installer touch the equipment after the original install. When a general roofer, a handyman, or the homeowner disconnects and remounts the panels without that credential, the manufacturer can treat the warranty as void from that point forward, even if the equipment itself never failed.
The risk is not just paperwork. Panels flex slightly during unmounting, and rough handling can introduce micro-cracks in the cells that do not show up as a visible fault right away but shorten the panel's working life. Racking hardware has torque specifications for a reason, and a re-mount that skips them can loosen a connection that later corrodes or arcs. None of that is covered once the manufacturer decides the warranty no longer applies.
It is not only the panels. Microinverters and string inverters from brands like Enphase and SolarEdge carry their own separate warranty, usually 10 to 25 years, with the same certified-installer condition attached. A roof crew that unplugs a microinverter housing without following the manufacturer's disconnect sequence can void that coverage on its own, independent of anything that happens to the panel above it.
What Do Manufacturer Warranties Actually Cover?
A solar installation actually carries three separate warranties, not one, and a removal job affects each of them differently. Knowing which is which tells you what you actually stand to lose.
| Warranty type | What it covers | What removal can void it |
|---|---|---|
| Product warranty | Manufacturing defects in the panel itself, typically 20 to 25 years | Handling damage or disconnection by an uncertified crew |
| Workmanship warranty | The original installer's labor: mounting, wiring, flashing, waterproofing | Reinstallation by a different, uncertified crew |
| Performance warranty | Guaranteed power output over the panel's rated lifespan | A remount angle, orientation, or shading change that was not documented |
Losing the product warranty means a genuine manufacturing defect years from now comes out of your pocket instead of the manufacturer's. Losing the workmanship warranty means a roof leak traced back to the panel mounts is your problem, not the original installer's.
Your own paperwork tells you the exact terms. Look for the phrase "authorized service provider" or "certified installer" in the warranty document your original installer gave you at closing — that clause, not a general sense of who is trustworthy, is what a manufacturer will point to if you ever file a claim.
How Do You Remove Solar Panels Without Voiding the Warranty?
The fix is procedural, not expensive. Follow a set order and the coverage carries forward with the panels.
- Call your original installer or the manufacturer's support line before any roofer touches the array.
- Get written confirmation of who is authorized to disconnect and remount your specific panel model.
- Have the crew record serial numbers and mounting torque specs before anything comes off the roof.
- Store the panels flat, boxed, and off the ground for the duration of the roof work.
- Reinstall through the same certified installer so the workmanship warranty carries forward without a gap.
- Get a written reinstallation inspection report and keep it with your original warranty paperwork.
Do not skip the utility step either. Most NJ and PA utilities treat a removal and reinstallation as a change to your interconnection agreement, and reconnecting the system without notifying the utility can delay net metering credits for a full billing cycle even after the warranty side is handled correctly.
This is exactly the point where a lot of homeowners hand the job to whoever is already standing on the roof, because coordinating a second contractor feels like extra friction. Solarnova removes and reinstalls solar panels as a standalone service across NJ and PA, using the same certified process regardless of who installed the system originally, so the manufacturer and workmanship coverage both carry forward. See how the removal and reinstall service works before your roofer starts.
What It Costs to Do This the Right Way
Professional removal and reinstallation costs more upfront than asking your roofer to unbolt the panels, and the warranty you keep is worth more than the difference. Removal-only work in New Jersey runs $1,500 to $4,500, and a job that includes reinstallation after the roof is finished runs $3,500 to $8,000. Pennsylvania pricing sits slightly lower: $1,400 to $4,200 for removal alone, $3,200 to $7,500 with reinstallation. A typical removal takes 4 to 8 hours on site, and reinstallation adds another 1 to 2 days depending on system size. If a battery such as a Powerwall is tied into the array, budget extra time for the certified disconnect and reconnect that its own warranty requires, on top of the panel work.
What About Panels That Are Already Out of Their Original Warranty?
Plenty of NJ and PA systems installed a decade or more ago are past the workmanship warranty and running only on the product warranty's tail end. Warranty protection still matters here, just differently: a product warranty claim on an older system is usually a prorated payout rather than a full replacement, so a defect that shows up right after an uncertified removal costs you closer to full retail than the small percentage a manufacturer might have covered. Certified removal and reinstallation is worth doing even on an older system, because it is the only way to keep whatever prorated coverage is left.
Is Professional Removal Worth It If My Roofer Already Offered to Handle It?
Most roofers are honest about not being solar-certified, but a few will offer to unbolt and reset the panels anyway just to keep the job under one contract. That is the most common way a warranty gets voided, because nobody involved intended to void anything — the roofer was trying to save you a phone call.
Run the math instead of the assumption. A residential system runs $15,000 to $30,000 installed, and the product warranty is meant to cover most of that value for 20 to 25 years. Paying a few hundred to a couple thousand dollars more for a certified removal and reinstall is small next to losing coverage on a system that size, especially since a cell-level defect can take years to show up and would otherwise be a full out-of-pocket replacement.
Protect Your Warranty Before the Roof Work Starts
The move that actually protects you is simple: get the removal and reinstallation quoted and scheduled with a certified crew before your roofer sets a date. Request a free Solarnova quote and you will have an itemized number for removal, storage, and reinstallation before anyone touches the array — most homeowners hear back within a day.
