You planned everything perfectly – solar panels installed, energy bills dropping, neighbors asking who you used.

Then your roofing contractor drops some news: your roof needs a full replacement before it starts leaking. And those solar panels? They all have to come off first.

If you’re a Long Island homeowner facing this situation, you’re not alone. Solar panel removal & reinstall is one of the most common – and most misunderstood – parts of the reroofing process. Done right, it’s smooth and your system comes back online just as efficient as before. Done wrong, it can void warranties, damage panels, or leave your system down for weeks.

This guide walks you through everything you need to know about solar panel removal and reinstall in Long Island – the process, timeline, costs, and what questions to ask your contractor.

Why You Need to Remove Solar Panels Before Reroofing 

Many homeowners assume roofers can just work around the panels. They can’t – at least, not safely.

Solar panels are mounted directly onto your roof deck via penetrating hardware. When a roofer replaces shingles, they need full access to the entire roof surface. Working around mounted panels:

• Leaves sections of the old roof untouched
• Creates improper shingle overlaps that lead to leaks
• Risks damage to wiring and mounting brackets
• Voids most roofing warranties

The safest and most thorough approach is always: remove panels → replace roof → reinstall panels. It adds cost, but it protects your investment on both ends.

How the Solar Panel Removal Process Works 

A qualified solar technician – not a general electrician or roofer – should handle the removal. Here’s what the process looks like:

System Shutdown

Before anything is touched, your solar system is safely powered down. This includes disconnecting from your inverter and the grid. On Long Island, PSEG requires notification before disconnection in some cases.

Panel Disconnection

Technicians disconnect each panel’s DC wiring. Cables are carefully labeled and secured so reinstallation is clean and accurate.

Panel Removal

Panels are unbolted from the racking system one by one. Each panel is inspected during removal for any pre-existing micro-cracks or damage – catching issues now saves trouble later.

Panel Storage

Panels are stored flat, padded, and protected from weather and foot traffic. This is a step many overlook – improper storage causes more damage than the removal itself.

Racking/Hardware Assessment

Mounting hardware is inspected. Old lag bolts and flashings come out with the old roof. New penetrations will be sealed and flashed during reinstallation.

What Happens to Your System During Reroofing 

Once your panels are safely removed and stored, reroofing proceeds as normal. 

Your solar system will be offline during this period – typically 1 to 3 days for the roofing work itself.

A few things to keep in mind during this phase:

• Battery storage: If you have a solar battery system, it may continue to provide limited backup from stored energy, but it won’t be charging during the outage.
• Grid connection: You’ll rely fully on PSEG grid power during the downtime.
• Inspection: Many Long Island municipalities require a roof inspection before solar reinstallation can proceed. Your contractor should coordinate this.

Solar Panel Reinstallation: Step-by-Step

Reinstallation is not just the reverse of removal – it’s a full re-mount that must meet current code requirements.

New Flashings and Penetrations

Before panels go back on, new waterproof flashings are installed at every roof penetration point. This is critical – improperly flashed mounts are the cause of roof leaks on solar homes.

New Racking Installation

Fresh racking hardware is mounted to the new roof deck. In some cases, the racking layout may be slightly adjusted to improve performance or comply with updated fire codes.

Panel Re-mounting

Panels are re-mounted in their original positions (or optimized positions if the layout is being updated). Wiring is reconnected per the original documentation.

System Testing

A full system test is run – inverter check, string voltage testing, and monitoring system verification. The system should perform at the same level as before removal.

Final Inspection and Grid Reconnection

A final inspection may be required before PSEG reconnects your system to the grid. Your contractor should handle this paperwork and scheduling.

How Long Does It Take? 

Here’s a realistic timeline for a typical Long Island reroofing project with solar:

The biggest variable is municipal inspection and PSEG processing time – both are outside your contractor’s control. Start the project with realistic expectations.

How Much Does Solar Panel Removal & Reinstall Cost on Long Island?

Solar panel removal and reinstallation cost on Long Island typically ranges from $1,500 to $4,000+, depending on:

• System size: More panels = more labor hours
• Panel type: Older or heavier panels take longer
• Racking condition: If hardware needs full replacement vs. reuse
• Access difficulty: Steep or multi-story roofs cost more
• Contractor coordination: Whether removal/reinstall is bundled with the roofing project

Many homeowners are surprised to find that solar removal and reinstall isn’t covered by their roofing contractor’s quote – always confirm this in writing before signing.

A few tips to manage costs:

• Get a combined quote from a solar company that also coordinates with roofers (or vice versa).
• Ask if your solar panel warranty covers removal/reinstall labor.
• Check if your homeowner’s insurance covers the work – especially if the roof replacement was triggered by storm damage.

 Long Island Homeowner Tip:
If your roof is 15+ years old and your solar system is under 10 years old, plan for reroofing before your panels’ warranty expires. That way, the removal/reinstall cost may still be partially covered.

Will Your Warranty Be Affected? 

This is the question most homeowners forget to ask – until it’s too late.

Panel manufacturer warranties typically remain valid after removal and reinstall if the work is done by a licensed, certified solar installer. Using an unqualified contractor or a roofer who “has done solar before” can void your panel warranty.

Inverter warranties are generally unaffected by the physical removal process, but any wiring errors during reinstall can create issues.

Roofing warranties are a separate matter – the new roof warranty will depend on who installs it and whether solar penetrations are properly flashed and documented.

Always ask your solar contractor to provide written documentation of the reinstallation, including photos of penetration flashings, for your warranty records.

Choosing the Right Contractor for the Job

Reroofing with solar is a coordination challenge. You’re dealing with at least two trades – roofing and solar – and potentially your municipality and PSEG on top of that.

The smoothest projects happen when:

You Use One Point of Contact

Some solar companies on Long Island coordinate directly with roofing contractors and manage the full project – removal, roof replacement, reinstall, inspection, and reconnection. This eliminates the “he said / she said” situation when problems arise.

You Verify Credentials

Your solar removal/reinstall contractor should be:

• Licensed in New York State
• Certified by the panel manufacturer (or at minimum, a certified solar installer)
• Experienced with PSEG interconnection procedures on Long Island

You Get Everything in Writing

Before the project starts, get written confirmation of:

• Exactly who is responsible for panel removal vs. reinstall
• How panels will be stored
• What happens if panels are damaged during removal
• Timeline and reconnection process

Conclusion

Reroofing when you have solar panels isn’t complicated – but it does require the right planning and the right team. Here’s the short version of what you’ve learned:

• Always use a licensed solar installer for removal and reinstall – not your roofer
• Expect 5 to 15 business days of total system downtime
• Budget $1,500–$4,000+ for removal and reinstall on Long Island
• Protect your panel warranty by getting written documentation of all work
• The smoothest projects use a single contractor who coordinates both trades

If you’re on Long Island and your roof is telling you it’s time, don’t wait until it becomes an emergency. Getting ahead of it means you can plan the downtime, protect your panels, and bring everything back online without surprises.

Frequently Asked Questions 

Can a roofer remove solar panels themselves?
Technically, some roofers attempt this – but it’s not recommended. Solar panel disconnection involves live DC wiring, which requires a licensed solar or electrical contractor. Having an unqualified person handle removal can void your panel warranty and create safety risks.

Do I need a permit to remove and reinstall solar panels in Long Island?
In most Long Island municipalities, a permit is required for solar reinstallation. Your solar contractor should pull this permit on your behalf. Skipping this step can create problems when you sell your home.

What happens if a panel is damaged during removal?
If damage occurs during removal, it’s typically the removing contractor’s liability – provided it’s documented. Always inspect panels before and after removal and get a written record. Your homeowner’s insurance may also cover accidental damage.

Can I upgrade my solar system while reroofing?
Yes – and this is actually a smart time to do it. Since the panels are coming down anyway, adding panels, upgrading your inverter, or adding battery storage during the same project can save on labor costs.

How do I find out if my solar panel warranty covers removal and reinstall?
Check your original panel warranty documentation or contact your solar installer. Most major manufacturers (LG, SunPower, Panasonic, REC) allow removal and reinstall without voiding the warranty as long as a certified installer performs the work.
