Solar on a midlife or failing roof often costs more than re-roofing first. Walk through this before you sign a panel contract.
What this checklist helps with
Solar installers optimize for production — not necessarily for your roof's remaining life. Removing panels for an emergency re-roof mid-lease can cost thousands. Walk this checklist before you sign a PPA, lease, or loan so sequencing, warranties, and HEAR rebates stay intact.
Safety notes
Roof penetrations and electrical work require licensed trades. Do not assume a solar sales rep's verbal roof assessment replaces a roofer's written inspection.
Common situations
- 15-year-old architectural shingles with active attic stains — re-roof before racking, not after.
- Panel upgrade needed for heat pump and solar — sequence MPU before inverter install.
- HOA requires matching shingle color — resolve before solar layout blocks south slope access.

FAQs
Can I install solar on a 10-year-old roof?
Maybe — if inspection shows 15+ years of useful life and flashing plan is written. Get roofer sign-off in writing.
Who pays for removal and reinstall?
Clarify in contract — many leases leave that cost on the homeowner if the roof fails early.
