Solar panel removal and reinstallation (R&R) is needed whenever work must be done on the roof beneath the panels. The most common reason is a full roof replacement.
Asphalt shingles reaching end of life (20-30 years). Most common R&R trigger.
75% of R&R jobsTargeted repair under or near panel mounts. May only need partial removal.
15% of R&R jobsNor'easter, hail, or tree damage requiring section replacement.
8% of R&R jobsSpray foam or blown-in insulation requiring roof deck access from above.
2% of R&R jobsR&R costs vary based on system size, roof pitch, number of stories, and racking type. Here is the itemized breakdown for a typical 8-12 kW residential system in Massachusetts.
| Line Item | Low Estimate | High Estimate | Notes |
|---|---|---|---|
| Panel & racking removal | $800 | $1,500 | Disconnecting panels, removing racking, safe transport to ground |
| Secure storage (panels & hardware) | $0 | $300 | On-site tarped storage or installer warehouse. Duration matters. |
| Reinstallation on new roof | $600 | $1,200 | New flashing, re-mount racking, re-attach panels, re-wire |
| Electrical inspection | $100 | $200 | Required by MA code after any solar system modification |
| Utility re-interconnection | $0 | $100 | Notification to Eversource/NGrid. May require re-inspection. |
| New flashing & sealant | $100 | $300 | Best practice: always replace flashing on re-install |
| Total R&R Cost | $1,600 | $3,600 | Solar removal & reinstall only (excludes roof cost) |
$1,200-$2,200
12-20 panels. Single-story roof. Standard pitch.
$1,500-$3,000
20-28 panels. 1-2 stories. Most common in MA.
$2,500-$4,500
28-40+ panels. Complex roof. Multi-story. Premium racking.
Coordinate solar crew schedule with roofing contractor. Book both before starting.
Solar crew disconnects system, removes panels, removes racking. Patches existing roof penetrations.
Roofing contractor replaces shingles/materials. No solar equipment on roof during this phase.
Solar crew installs new flashing, re-mounts racking on fresh roof, re-attaches panels, re-wires.
Municipal electrical inspection + utility re-interconnection approval. System back online.
Removing and reinstalling solar panels can affect multiple warranties. Here is how to protect yourself.
Risk: Voided if removed by non-certified installer
Protection: Use a licensed solar installer. Keep documentation of the removal/reinstall.
Risk: May be voided if disconnected improperly
Protection: Use an Enphase-certified or SolarEdge-certified installer for the work.
Risk: Usually voided once another company touches the system
Protection: Ask your original installer first. If they cannot do it, get written confirmation that R&R by a third party will not void their warranty.
Risk: Roofer may not warranty areas with solar penetrations
Protection: Coordinate so the solar installer does roof penetrations after the roofer completes their work. Get the roofer to confirm their warranty covers the full roof.
Voided solar warranty, electrical code violation, potential roof damage from improper handling
Always hire a separate licensed solar installer for R&R
Roof leaks within 1-3 years. Old flashing does not seal properly to new shingles.
Insist on new flashing and sealant for every mount point
Damaged panel or loose connection goes undetected. Lost production for months.
Run a full system test and compare output to pre-removal baseline
SMART payment gap. Possible net metering billing issues.
Notify Eversource/NGrid and MassCEC before the removal date
Panels removed but roofer is not available for 2 weeks. System offline unnecessarily.
Book both crews before starting. Solar removal should be 1 day before roofing starts.
NuWatt handles solar panel removal and reinstallation for Massachusetts homeowners getting a new roof. We coordinate with your roofing contractor so you do not have to manage two separate projects.
Need a new roof and want to upgrade your solar system at the same time? NuWatt offers combined packages through our network of licensed Massachusetts roofing partners. One project, one point of contact.
Solar + Reroof packages include:
R&R adds $1,500-$3,500 to your roof replacement project. But compared to the value your solar system provides, it is a small cost to keep a $30,000-$45,000 asset operational for another 15-20 years.
$1,500-$3,500
One-time cost for removal and reinstallation
$3,300-$4,200/yr
Net metering + SMART for a typical 11 kW MA system
4-10 months
R&R cost recovered from continued solar savings
Solar panel removal and reinstallation (R&R) in Massachusetts costs $1,500-$3,500 in 2026. The cost depends on system size (number of panels), roof complexity (pitch, stories, access), racking type, and whether new flashing is needed. This does not include the cost of the roof replacement itself.
The solar work itself takes 2-3 days (1 day removal, 1-2 days reinstallation). The total timeline including roof replacement is typically 2-4 weeks from start to finish. The biggest delays are scheduling coordination between solar and roofing crews and waiting for the municipal electrical inspection after reinstallation.
It depends on who does the removal. If the original installer or a certified dealer removes and reinstalls the panels, most manufacturer warranties remain intact. If an unlicensed person removes them, the panel manufacturer warranty may be voided. Enphase microinverter warranties require installation by a certified Enphase partner. Always use a licensed solar installer for R&R.
Before. If your roof is 15+ years old or has fewer than 10 years of remaining life, replace it before going solar. Solar panels last 25-30 years. Installing on an old roof means you will need R&R in 5-10 years at $1,500-$3,500. Replacing the roof first avoids this cost entirely.
You need a licensed solar installer. Solar panel removal involves electrical disconnection (DC voltage up to 600V), which requires a licensed electrician. Roofers are not qualified to handle solar electrical systems. Using a roofer risks voiding your solar warranty and violating Massachusetts electrical code.
Yes. Your system will be offline during the entire roof replacement period (typically 1-3 weeks). You will not generate electricity or earn net metering credits during this time. For an 11 kW system producing ~36 kWh/day, a 2-week outage costs approximately $200-$300 in lost production.
Yes. NuWatt offers a full R&R service for Massachusetts homeowners. We coordinate with your roofing contractor, remove and safely store your panels, reinstall on the new roof with new flashing, and handle the electrical inspection and utility re-interconnection. We also offer combined roof + solar packages through our network of licensed roofing partners.
Your SMART 3.0 enrollment is tied to the system at your address. A temporary removal for roof replacement does not cancel your SMART contract. However, you will not receive SMART payments for the period the system is offline. Notify MassCEC of the temporary disconnection to keep your enrollment in good standing.
