Roof Replacement With Existing Solar Panels: Costs, Permits and Steps

Roof replacement with solar panels already on the house means a solar contractor must remove the panels, the roofer replaces the roof, and the solar contractor reinstalls and recommissions the system. Removal and reinstallation alone commonly runs a few thousand dollars, on top of the roof itself, and the whole process can take weeks to months because of permits and scheduling.

Planning ahead, using the right contractor and protecting your warranties can keep the cost and downtime under control.

Key takeaways

• EnergySage (updated May 2026) estimates $200 to $300 per panel to remove and reinstall, possibly over $7,000 in total.
• Angi's 2025 data puts removal at $200 to $500 per panel and reinstallation at $50 to $100 per panel.
• Some building departments, such as Santa Cruz County, California, require an electrical permit and inspection for reinstalling a system, in addition to a reroof permit.
• Tesla requires the new roof to sit for 30 days before reinstalling and says permitting can take up to about two months.
• Hiring an outside contractor can affect warranties. Check your installer and lease terms first.

How roof replacement with solar panels works

The basic sequence is the same almost everywhere:

1. Inspect and plan. Have the roof and solar system checked. Note any damaged panels, wiring or mounts.
2. Get permits. Your solar contractor and roofer pull the required permits.
3. Shut down and remove. A qualified solar crew disconnects the system and removes panels, racking and attachments. Qcells' North American manual says installation, maintenance, grid connection and dismantling should be carried out by trained and qualified electricians.
4. Store panels safely. Tesla, for example, asks homeowners to provide a safe storage spot during the work.
5. Replace the roof. The roofer installs new roofing, flashing and underlayment.
6. Reinstall and reconnect. The solar crew installs new flashing and mounts where needed, reinstalls panels and reconnects wiring.
7. Inspect and restart. The building department inspects, and the system is turned back on.

How much does it cost to remove and reinstall solar panels for a new roof?

These ranges come from two consumer cost guides, checked in November 2026. Treat them as rough national figures and get local written quotes.

Cost item	Typical range	Source
Remove and reinstall, per panel	$200 to $300	EnergySage, May 2026
Remove and reinstall, total	$1,500 to $6,000, possibly over $7,000	EnergySage, May 2026
Removal only, per panel	$200 to $500 (average $250)	Angi, 2025 data
Reinstallation, per panel	$50 to $100	Angi, 2025 data
New mounting hardware, per panel	$40 to $60	Angi, 2025 data
Grid disconnection	$400 to $600	Angi, 2025 data
Permits	$150 to $1,000	Angi, 2025 data
Roof replacement (separate)	About $5,800 to $13,200	Angi, 2025 data (table figure)

For a 20-panel system, EnergySage's per-panel range works out to about $4,000 to $6,000 for removal and reinstallation (our calculation), before the roof itself. Angi notes that steep or high roofs, damaged roofing and older systems with weathered mounts all push the cost up.

Permits and inspections for roof replacement with solar panels

Rules are local, but two examples show what to expect:

• Santa Cruz County, California requires an electrical permit to remove and reinstall a PV system, plus a reroof permit if the roof is replaced. The reinstallation must match the original approved layout, and the qualified person who reinstalled it must attend the final electrical inspection.
• Wheaton, Illinois requires the permit application to name both a solar installation company with an active electrical license and an Illinois state-licensed roofer. The manufacturer's removal and reinstallation specifications must be submitted, and reinstallation must match the original approved configuration. If the original layout no longer meets current code, the Building Official must approve a written request first. The city does one final electrical inspection.

Both examples show a common theme: reinstallation is expected to match what was originally approved. If the old layout no longer meets current code, changes may be needed. Tesla's support page notes that if code has changed since installation, permits or system upgrades may be required, at the owner's cost. Call your building department early to ask what applies to you.

Timeline: how long will the panels be off?

Plan for longer than the roofing job itself. From Tesla's published process:

• Tesla follows up on removal requests within about 7 to 10 business days.
• Permitting can take up to about two months on average.
• After reroofing, the roof must sit for 30 days with no additional work before panels go back on.
• In Colorado, Tesla requires a copy of the passed roof inspection before scheduling reinstallation.

Other installers have their own rules, but the lesson is the same: start early, and expect to lose some production while the system is down. You can estimate the lost kWh for those weeks with our solar panel calculator.

Changing roof materials? Check compatibility first

A new roof is a chance to switch materials, but the solar mounts must work with whatever goes on. Tesla's support page tells customers changing roof type to confirm the new type is eligible. It lists comp shingle, concrete flat and round tile, standing seam metal, rolled torch down and foam as eligible, varying by state, and says it does not install on clay tile, metal tile, metal shingles, slate or wood shake, among others. Other installers have their own lists.

Angi notes that switching roof materials, such as from shingles to tile, can mean new mounting hardware, which a solar contractor it quotes estimates at $1,500 to $4,000 depending on how many panels you have. If storm damage is what forced the new roof, Angi adds that homeowner's insurance may cover removal and reinstallation, depending on your coverage. Ask your insurer before work starts, and keep receipts for every line item. Our guide on whether homeowners insurance covers solar panels covers the questions to ask.

Warranties, leases and who should do the work

Use your original installer if you can

EnergySage recommends contacting your original installer to remove and reinstall panels. If you cannot reach them, other solar companies offer operations and maintenance services, and many installers can refer you to a roofer. Tesla says that if you hire a third-party contractor, it is not responsible for their workmanship and your existing system warranty may be voided.

Know what the panel warranty does not pay

EnergySage warns that once panels are removed, the panel manufacturer's warranty usually becomes void, and that an existing roofing warranty often becomes void when solar is installed, at least for the portion covered by panels. Even when a panel warranty survives, it may not pay labor. The Qcells limited warranty dated October 1, 2025, does not reimburse costs for dismantling or installing modules.

Leases and PPAs

If you lease or have a power purchase agreement, the solar company owns the equipment, so contact it before anyone touches the system. Tesla notes that your energy contract stays active and monthly payments continue during removal and reinstallation. Read our guide on how a solar lease works.

Quality checks after reinstallation

• Ask for photos of new flashing at every roof attachment before panels go back on.
• Confirm that single-use parts were replaced. Qcells says grounding clips and washers known as WEEB parts must not be reused after removal.
• Get the final inspection sign-off in writing.
• Check your monitoring app for a full week of normal production on sunny days.
• Make sure critter guards, snow clips or other add-ons were put back if you had them.

Should you replace your roof before going solar instead?

If you do not have solar yet, the cheapest removal is the one you never need. EnergySage notes asphalt roofs usually last about 30 years and suggests replacing an asphalt roof older than about 10 years before installing solar. Read should I replace my roof before installing solar.

Next steps

Call your original installer or leasing company first, then your building department. Get written quotes that list removal, reinstallation, new hardware, permits and any code upgrades separately.
