A roof replacement on a typical Martinez home is a short job once the crew arrives. Add a solar array and the same project picks up a second trade, a second permit, a second inspection and a stretch of days when the panels sit in the garage instead of on the roof. That is no reason to delay a roof that needs work, but it makes the order of operations matter more than the shingle color.
The pressure comes from a mismatch in lifespans. Panels are built to produce for 25 years or longer, while a composition roof installed in the early 2000s across Contra Costa County may be close to the end of its run. When the roof under an array fails first, the homeowner pays twice for the same panels to come off and go back on. The work below follows how a roofing job actually unfolds when solar is already up there, from the first ladder climb to the day the system reconnects.
Getting Martinez solar removal lined up properly starts with a roofer who can tell you whether the roof under the array truly needs replacing. Affordable Roofing Systems, a family-owned Contra Costa County roofer since 1989, handles full roof replacement with a tear-off down to the deck, new flashings and ventilation, and city permits pulled by its own office. When a roof still has years left, the crew sticks to roof repair and says so plainly rather than selling a new one. Bring your solar company’s contact details to the first visit so the roofing dates can be set around the removal and reinstall window instead of colliding with it.
The Job From Ladder to Reconnection
| Stage | What happens | Who handles it | What to plan for |
|---|---|---|---|
| Roof inspection | Roofer checks open roof areas, edges of the array and the attic below the mounts | Roofer | Panels hide part of the roof, so ask for photos and attic findings |
| Keep or remove decision | Remaining roof life is weighed against how long the array will stay up | Roofer and homeowner | A small repair may not justify lifting the whole array |
| Solar coordination | Solar company quotes removal and reinstall, pulls its own permit, books a crew | Solar company or leasing company | Lead times, stamped plans and lease terms |
| Removal | System is shut down, panels and racking come off and get stored | Solar company | Storage space and days without solar production |
| Roof work | Tear off, deck repair, underlayment, shingles and flashing at future mount points | Roofer | Agree in writing who flashes the new mounts |
| Reinstall | Racking goes back on, panels are rewired and tested | Solar company | Electrical inspection and a monitoring check |
| Closeout | Both permits are finaled and paperwork is collected | Both trades | Keep roof and solar warranties together |
What Each Stage Looks Like Up Close
The inspection. A roofer can see the field of the roof, the ridges and the valleys, but the shingles under an array stay hidden. Good inspections lean on clues around it: granule loss at the panel edges, debris packed under the rails, and attic stains below mount locations.
The keep or remove call. If the roof has roughly a decade or more of life and the trouble sits away from the panels, a targeted repair often makes sense. If the roof is near the end and the array is expected to stay for another twenty years, replacing now while the panels are coming off anyway is usually the cheaper path over time.
Lining up the solar side. Removal and reinstall is permitted work in its own right. Nearby San Pablo, for example, requires a separate electrical permit for taking an existing system off and putting it back, lists the license types allowed to do it, and tells owners of leased systems to work through the leasing company. Contra Costa County’s own permit records show inspectors asking for the original reviewed and stamped solar plans to be on site at inspection, so dig those out early. If the array is leased, the lease contract may dictate which crew is allowed to touch it.
Roof work under a cleared array. With the panels gone, the roofer can tear off, replace any soft decking and run new underlayment across the whole surface. The detail that causes the most finger pointing later is the mount flashing. A typical residential array uses dozens of roof penetrations, and racking maker IronRidge notes that roofing manufacturer flashing instructions have to be followed to stay within code and keep the roof warranty. Before work starts, settle whether the roofer installs flashed mounting points during the reroof or the solar crew flashes its own mounts afterward.
Reinstall and sign off. The solar crew remounts the racking, reconnects the panels and tests the system, then the electrical permit gets its inspection. Once the system is back on, check the monitoring app for a few days to confirm every panel is reporting.
Two Warranties Have to Survive the Job
A reroof under solar touches two separate warranty chains, and they do not always line up. Solar Power World reviewed the policies of the major shingle makers and found that Owens Corning keeps its shingle warranty in force when solar is installed, while Malarkey allows solar but excludes damage caused by the installation from coverage. In plain terms, the shingle warranty often survives, but a leak at a poorly flashed mount becomes the installer’s problem, not the manufacturer’s.
The solar side has its own conditions. Many installers only stand behind their workmanship if their own crew or an approved partner handles removal and reinstall. Ask the original installer before hiring a different solar company for the job, because a cheaper quote can cost the rest of a workmanship warranty. Save the roofing warranty, the solar workmanship warranty, both permits and the inspection sign-offs in one folder.
Timing the Work Around Martinez Weather
Schedules tighten as the rainy season approaches in the East Bay. Solar crews tend to book out in fall, and permit review adds days before removal can even begin. Homeowners who start the roof inspection in late summer or early fall usually have the easiest time fitting removal, roofing and reinstall into a single dry window. Waiting for the first winter leak often means a temporary patch now and the full sequence later.
The roof itself might take only a couple of days. The calendar around it is what takes planning, and getting both trades talking before anyone climbs up is the step that keeps the whole project on track.
