Why Solar Panel Removal and Reinstallation Is Required

You cannot replace a roof with solar panels still attached. The panels have to come off first, the roofing work gets done, and then the panels go back on with new flashing and properly sealed mounting points. If this process is not handled correctly, you risk roof leaks around the penetrations, microcracks in the panels from improper handling, connector damage, and voided warranties on both the roof and the solar system.

That is why it matters who does this work. A roofing contractor who has never removed solar panels is guessing. A solar company that does not replace roofs has no stake in what happens under the panels. Home Pro does both, which means the people removing your panels are the same people installing your new roof and putting everything back together.

Our Solar Panel Removal and Reinstallation Process

1. System evaluation and planning Before any panels come off, we evaluate your existing solar system, racking layout, roof condition, and electrical components. This tells us exactly what is needed and lets us plan the project so there are no surprises once work begins.

2. Panel removal and on-site storage Our team carefully disconnects and removes solar panels, racking hardware, and related components. Panels are stored safely on site until reinstallation. Every connector, wire, and mounting point is documented before removal.

3. Roof replacement With the panels off, roof replacement proceeds without obstruction. We install your new roofing system — whether GAF Timberline, CertainTeed Solaris, TPO flat roofing, or standing seam metal — with proper underlayment, ventilation, and flashing at every penetration point.

4. Panel reinstallation, cleaning, and testing Once the roof is complete, panels are cleaned to remove dirt and buildup that affects efficiency. We reinstall using proper flashing, updated mounting hardware, and correct alignment. The system is tested before the project is closed out to confirm everything is producing as expected.

Owned, Leased, and PPA Solar Systems

Owned solar systems If you own your solar system outright, we can typically handle the full removal and reinstallation process directly. This is the most straightforward path and allows for the fastest project timeline.

Leased or PPA solar systems Some leased and PPA solar systems require coordination with the original installer or system owner before work can begin. Requirements vary by provider and may include inspections or approvals. We have worked with systems from SunPower, Sunrun, Tesla Energy, and other providers and will guide you through exactly what your situation requires.

What Does Solar Panel Removal and Reinstallation Cost?

Most projects run between $200 and $300 per panel, depending on racking type, system age, and whether any upgrades are needed during reinstallation. A typical 20 to 25 panel system totals between $4,000 and $7,500.

Additional costs may apply for:

• Damaged or corroded racking that needs replacement
• Wiring or conduit repairs uncovered during removal
• Critter guard removal and replacement
• Upgraded mounting hardware
• New flashing at all roof penetrations

Every project gets a clear written estimate before work begins. There are no surprise charges.

Permit costs are passed through at actual cost. Plan sets typically run around $250, and each city has its own permit fees. Home Pro handles the full submittal, tracks the approval, and coordinates the final inspection.

Smart Upgrades to Consider During Your Project

When the panels are off and the electrical system is already open, this is the lowest-cost time to make improvements. Many homeowners take advantage of the timing to add or upgrade equipment they have been considering.

• Add battery backup storage Under California's NEM 3.0 rate structure, battery storage is the most effective way to maximize the value of your solar system. PG&E pays significantly less for solar energy exported to the grid during the day, so storing that energy for evening use makes a real difference in your monthly bill. We install Tesla Powerwall 3, Enphase IQ Battery, and FranklinWH systems for both new and existing solar setups. Adding storage while the roof and solar work is already underway saves a separate mobilization cost.
• Upgrade solar panels If your panels are more than 10 to 12 years old, a reroof is a good time to evaluate whether newer, higher-efficiency panels make sense for your system. We coordinate upgrades through our trusted partners Solar Tech and Axia by QCells.
• Add an EV charger If you are also adding an EV charger, combining it with your roofing and solar project is the smartest way to do it. The electrical work is already underway, which reduces installation cost and eliminates a second visit from an electrician. Learn more about our EV charger installation.
• Replace aging inverters Inverters typically last 8 to 12 years. If yours is approaching that range, reroofing is the ideal time to replace it before it fails.
• New racking systems Modern racking improves attachment points, long-term durability, and compatibility with today's panel designs.
• Critter guards Pigeons and rodents nesting under solar panels cause wiring damage and fire risk. Critter guards are easy to install during reinstallation and are much harder to add after the fact.

Permits and Inspections

Solar panel removal and reinstallation requires a permit in most Bay Area cities. The permit process involves a plan set submittal, city review, and a final inspection once the work is complete. Home Pro manages the entire process — you never have to call the city or track down an inspector yourself. Permit costs are passed through at actual cost with no markup.

Frequently Asked Questions

How long does solar panel removal and reinstallation take? Most projects take one to two days for removal and one to two days for reinstallation, depending on system size. Combined with the roof replacement, most full projects are completed in five to seven days.

Will my solar system stop producing power during the project? Yes. Production pauses while the panels are off and resumes once they are reinstalled and the system is tested. Most homeowners plan around two to four days of downtime depending on project scope.

Do I need a permit for solar removal and reinstallation? In most Bay Area cities, yes. Solar removal and reinstallation typically requires a permit and a plan set. Home Pro handles the full permit process, including submittal, tracking, and final inspection coordination. Plan sets typically run around $250, and permit fees vary by city.

Can you work with leased or PPA solar systems? Yes, in most cases. Some leased or PPA systems require coordination with the original installer or system owner before work can begin. Requirements vary by provider. We guide you through exactly what your system requires.

Will removing my panels void my solar warranty? Not if the work is done correctly. We follow manufacturer specifications for removal, handling, cleaning, and reinstallation. If your panels are under warranty, we document our process to protect your coverage.

Should I add battery storage during my solar removal and reinstallation project? Many homeowners do, and the timing makes sense. Under NEM 3.0, battery storage significantly improves the value of your solar system. Since the electrical work is already open during the reroof, adding storage at this stage is more cost-effective than scheduling a separate project. Learn more about our battery backup options.

Can I add an EV charger at the same time? Yes. Combining an EV charger installation with your roofing and solar project is the most cost-effective way to do it. The electrical system is already being worked on, which eliminates a second mobilization cost. Learn more about EV charger installation.

Can I upgrade my panels at the same time? Yes. If your panels are more than 10 years old, a reroof is a good time to consider upgrading to newer, higher-efficiency panels. We coordinate panel upgrades through our trusted solar partners.
