Key points
- Identify who owns and services the solar system
- Write down removal, storage, and reinstallation scope
- Coordinate roof penetrations and both warranties
- Require post-installation testing and closeout records
Start with the solar agreement and system identity
Determine whether the array is owned, financed, leased, or covered by a power-purchase agreement. Locate the original installer, equipment list, monitoring account, warranty documents, and any transfer or service terms. Do not authorize another company to disconnect or alter equipment until you understand whether the agreement restricts who may perform that work.
Make responsibility explicit before scheduling tear-off
The written plan should identify who shuts down the system, obtains any required electrical or building approvals, removes modules and mounting components, labels and stores equipment, protects wiring, coordinates roof access, reinstalls the array, reconnects monitoring, and resolves damage or delay. A roofer saying that solar will be handled is not a complete scope.
Coordinate roof penetrations and flashing
Ask the roofer and solar contractor to agree on deck repairs, underlayment, attachment locations, flashing method, sealants where specified, and who documents concealed conditions. Confirm whether existing mounts will be reused or replaced and how the completed penetrations affect the roofing workmanship, roofing-product, racking, and solar-installation warranties.
Build one schedule with handoff gates
Write down the removal date, weather contingency, roofing start, dry-in milestone, completion inspection, reinstallation date, and expected period without solar production. Identify who can release the roof for reinstallation and what happens if decking repairs, unavailable parts, failed equipment, or inspection delays extend the project.
Compare separate and combined proposals fairly
A single roofing-and-solar company may simplify coordination, while separate specialists may provide clearer expertise for an existing system. In either structure, require itemized prices, the exact contracting identities, current licensing appropriate to each scope, insurance evidence, exclusions, payment milestones, and warranty responsibility. Do not compare a roofing-only proposal with a combined removal-and-reinstallation proposal as if they include the same work.
Require final testing and records
After reinstallation, obtain photographs of attachment and flashing details before panels conceal them, an equipment inventory, testing or commissioning results, confirmation that monitoring is communicating, permit or inspection closeout when applicable, and written instructions for reporting a roof leak or solar fault. Compare production over an appropriate period rather than assuming same-day output proves full performance.

Do solar panels have to come off for roof replacement?+
The U.S. Department of Energy states that the panels and mounting system need to be removed to complete a roof replacement. A property-specific plan should identify who performs removal and reinstallation.
Should the roofer or solar installer remove the panels?+
Use a party authorized and qualified for the solar scope under the system agreement, licensing rules, equipment requirements, and warranties. The roofing and solar responsibilities should be separate in writing even if one company performs both.
What should a solar removal and reinstallation quote include?+
It should identify shutdown, equipment inventory, removal, labeling, storage, wiring protection, mounts and flashing, reinstallation, testing, monitoring reconnection, permits or inspections when applicable, schedule, exclusions, and warranties.
Can roof and solar warranties conflict?+
They can create gaps if responsibility for penetrations, flashing, leaks, equipment damage, or later service is unclear. Ask both parties to state in writing how their work affects existing and new warranties.
