Your roof needs replacing, but there's a solar array sitting on it. This is one of the most common — and most mishandled — situations in residential solar. Done right, it's a smooth "detach and reset" project. Done wrong, it voids warranties, damages equipment, and starts finger-pointing wars between your roofer and whoever touched the panels. Here's what to expect.
Why your roofer won't touch the panels
Almost no roofing company will remove solar panels, for good reasons: panels produce live DC voltage whenever light hits them, improper handling voids manufacturer warranties, and roofers' insurance typically excludes solar work. The standard approach is a coordinated project: a solar professional removes and stores the panels, the roofer replaces the roof, and the solar pro reinstalls with new flashing.
What it costs in 2026
- Full detach-and-reset: typically $2,800–$4,800 for an average residential system (roughly $250–$400 per panel)
- Larger systems: complete projects can run $6,000–$12,000 for big arrays
- Storage: if panels must be stored off-site between removal and reinstall, expect $25–$50 per panel per month
- The roof itself: $5,800–$13,200 for typical asphalt replacement, separate from solar costs
The process, step by step
- Pre-project audit. The solar pro documents system condition and production baseline before touching anything. This protects everyone.
- Utility coordination. The system is safely de-energized and, where required, the utility is notified.
- Removal (usually 1 day). Panels, racking, and wiring come off; everything is labeled and stored. Mount locations are marked.
- Roof replacement (1–3 days). The roofer works on a clear deck — faster and better quality than working around an array.
- Reinstallation (1–2 days). New flashing at every mount point (never reuse old flashing on a new roof), panels reinstalled, torque-checked, and rewired.
- Recommissioning. System restarted, monitoring verified, production compared against the pre-project baseline.
With good scheduling, panels are typically off the roof for just 2–5 days.
Questions to ask your solar pro
- Will you coordinate scheduling directly with my roofer?
- Where are panels stored, and is storage insured?
- Are new flashings and sealing included in the quote?
- Do you warranty the reinstallation workmanship?
- Will you verify production after recommissioning?
What if your original installer is gone?
You don't need them. Any certified solar professional can perform a detach-and-reset — it's routine work. If your installer went out of business, see our guide on what to do when your solar company shuts down, then look at roof replacement coordination services or find a vetted removal pro near you.
One more thing: timing
If your roof is within 5 years of needing replacement and you're planning solar work anyway, coordinate both. Paying for detach-and-reset twice — or putting a 25-year solar array on a 5-year roof — are the two most expensive scheduling mistakes in residential solar.
