The short answer
If your roof has less than ~10 years of life left, replace it before installing panels — otherwise you'll pay to detach and reset the whole array later. If you need a new roof anyway, the Tesla Solar Roof combines a new roof and solar into one integrated system with a single 25-year warranty for the roof and the power it produces.

The detach-and-reset trap
Solar is warrantied for 25+ years. If your roof fails in year 8, you'll pay for solar panel removal and reinstallation — detaching the whole array, re-roofing underneath it, and resetting every panel. Re-roofing first avoids that — and as an Owens Corning Roofing Preferred Contractor, we handle premium shingle re-roofs ourselves, so the new roof and the solar are planned as one project.
And if you're replacing the roof anyway, the Tesla Solar Roof is the integrated answer: tempered-glass solar tiles that are the roof, installed by our Tesla Premier Certified team — one installer, one 25-year warranty for roof and power, and no finger-pointing if anything ever leaks.
FAQ
If your roof has less than about 10 years of life left, yes — replace it first. Otherwise, when the roof fails mid-warranty you'll pay to detach the whole array, re-roof underneath it, and reset every panel. If the roof is sound, you can go straight to solar.
You pay for solar panel removal and reinstallation — detaching the array, re-roofing underneath, and resetting every panel — because solar is warrantied for 25+ years and will outlast a roof that's near the end of its life. Re-roofing first avoids that cost, which is why we assess roof condition before any solar design.
Yes. As an Owens Corning Roofing Preferred Contractor we handle premium shingle re-roofs ourselves, so the new roof and the solar are planned and installed as one coordinated project. If you're replacing the roof anyway, the Tesla Solar Roof integrates both into one surface with a single 25-year warranty for the roof and the power it produces.
Review roof condition and solar design together before choosing reroofing, removal and reinstallation, or a new system.
