Should you get a new roof before solar panels?
Short answer. If your roof has less than about 10 to 15 years of life left, replace it before installing solar. Panels usually stay up 25 years or more, and removing and reinstalling them later for a roof replacement adds significant cost and the risk of disturbing wiring and mounts.
Why the order matters
A solar array and the roof under it should wear out on roughly the same schedule. Put new panels on a 15-year-old shingle roof and you will likely pay to detach, store and reinstall the whole system partway through its life. That work involves an electrician or solar company, new roof attachments and recommissioning, and it can stretch a one-day roof job into weeks of coordination.
How to judge the roof you have
- Age: architectural shingles in Georgia typically last about 20 to 30 years. A roof past 10 to 15 years deserves a hard look.
- Condition: granule loss, curling, cracked shingles or past leaks on the slopes where panels will go are red flags.
- Hidden issues: soft decking or old leak stains in the attic under the planned array area.
Coordinating the two jobs
- Have the roofer finish first, then the solar installer mounts panels with flashed attachments into the rafters.
- Agree in writing who is responsible for leaks at each solar penetration, since roofing workmanship warranties usually exclude work done by others.
- Ask the roofer to keep vents and pipe boots out of the sunniest areas where practical.
- Price the project without the federal residential solar credit, which ended for homeowner-owned systems after 2025, unless your tax preparer says otherwise.
The full case is in replacing your roof before solar, and lifespans by material are in how long a roof lasts in Georgia.
