Texas is hail country, which makes roofing and solar permanent neighbors: a huge share of solar prospects need a roof first, and a growing share of existing solar customers need panels off and back on so a roofer can work. Both situations are really sequencing problems — two trades, up to two permits, an insurance clock, and (for existing systems) a utility relationship that doesn't pause just because the array came down. Teams that run this as a defined play close roofs-plus-solar deals competitors walk away from.
New solar on a roof that needs replacing
The rule is blunt: never rack on a roof you'll be tearing off within the array's first decade. The sequencing that works:
- Roof evaluation at the solar site survey. Age, condition, and hail history — captured with photos. Selling solar onto a failing roof creates the industry's worst warranty and reputation outcomes.
- Reroof permit first (where required), roof completed and inspected, then the solar permit lands on a documented-new roof. Reroof permitting varies by Texas city — some permit all reroofs, some exempt like-for-like shingles; check the AHJ profile.
- Coordinate the structural story. If the AHJ wants structural documentation, the engineer should see the new roof assembly — decking condition and any re-deck become part of the attachment detail.
- Mind the insurance clock. Hail-claim roofs run on insurer timelines; promise solar dates keyed to roof completion, not contract signing. A combined roof+solar proposal with honest sequencing beats two vendors pointing at each other.
Detach-and-reset on existing systems
When an insured roof replacement hits a home with solar, the detach-and-reset (D&R) is its own mini-project with traps:
- Permits. Many AHJs treat a D&R reinstall as permit-triggering electrical work (the system is being disconnected and re-terminated); some treat a same-layout reset lightly. Know the city's posture before quoting — an unpermitted reset that later fails a utility check or resale inspection lands on you.
- The utility question most crews skip. The system will be de-energized and re-energized, and the as-built must still match the interconnection of record. Same equipment, same layout: generally a non-event. But if the D&R becomes an upgrade — new inverter model, added panels, added battery — the interconnection application needs amending before the new configuration operates, or you've recreated the energize-early problem on an existing account.
- Layout changes re-open the attachment design. New penetration locations mean the old structural detail no longer describes the roof — loop the engineer where the AHJ's posture requires it.
- Warranty chain-of-custody. Document module serials, torque values, and flashing details on removal and reset; the roofer's warranty, the racking warranty, and the module warranty all meet at your photos.
Running it as a product
Whether you self-perform roofing, partner, or just coordinate, the play is the same: a roof-condition gate at survey, a D&R checklist (permit posture, utility notification, structural trigger, photo protocol), and one schedule that both trades and the homeowner can see. In TexPTO you build those gates out of required stage-checklist items — "new roof complete and inspected" on Survey, a D&R utility-notification check before install — and a required item that isn't done keeps the job from leaving that stage. Checklists are set per stage for the whole org, not per job type, so word the items to work on every job that passes through.
FAQ
Should the roof or the solar go first? Roof first, always, when replacement is foreseeable — with the solar permit designed against the completed new roof.
Does a detach-and-reset need a permit in Texas? Frequently yes as electrical work, with city-by-city variation on like-for-like resets — confirm the AHJ's posture before quoting.
Do we have to tell the utility about a D&R? For a true like-for-like reset, practice varies; for any equipment or layout change, yes — amend the interconnection before re-energizing the changed system.
Who coordinates insurer timelines? Whoever wants the deal. Combined proposals with honest roof-then-solar sequencing win precisely because most vendors won't own the whole timeline.
