Posted by The most common reaction when a homeowner with solar finds out they need a new roof is some version of: can’t you just work around the panels?
The short answer is no, not if you want the roof done correctly. The panels have to come off first. Roofing around them leaves the installation incomplete in exactly the spots where water intrusion is most likely to develop over the next few years. The solar panel detach and reset process is well-established and when handled by a contractor with real experience doing it, your system comes back online performing exactly as it did before. Here’s how it works and what to nail down before the job starts.
Why They Can’t Stay Up During Roofing Work
Solar panels mount through the roofing material directly into the deck. When a crew replaces shingles, the array is physically in the way. Working around it leaves underlayment incomplete in those areas, puts new fasteners in the wrong positions relative to the mounts, and creates gaps in the flashing around every penetration point.
Those penetration points are where water finds its way in. A roof replacement done with panels left in place looks finished from the ground but has a series of built-in vulnerabilities that show up as leaks two or three years later.
The panels themselves are at risk during roofing work too. The vibration, foot traffic, and equipment involved can crack or damage panels even when workers are being careful. Full removal is the only way to protect both the panels and the integrity of the new roof underneath them.
What the Job Looks Like Step by Step
Panels get disconnected from the electrical system, pulled from the mounting hardware, and stored safely while the roof work happens. After the new roof is complete and inspected, mounting hardware goes back on in the correct positions for the new roofing system, flashing around each penetration is done as part of the roofing work itself, and the panels go back up.
In Texas, the electrical disconnection and reconnection has to be handled by a licensed electrician or qualified solar technician. That’s a legal requirement. The roofing side falls under TDLR licensing. Some contractors carry both capabilities in-house. Others bring in a qualified electrical sub. Either setup works as long as the right credentials are covering both sides of the job.
Will the System Work the Same After?
Yes, when it’s done right. Same panels, same inverter, same electrical configuration. Once everything is back in place and the connections are made, production should match what you were seeing before the roof work started.
In the first week or two after reinstallation, check your monitoring app or inverter display and compare production to your historical baseline. An incompletely seated connection can reduce output and the fix is simple if you catch it early. It doesn’t happen often but it’s worth a quick check.
Atrium Roofing manages the detach and reset process as part of its full roofing service in San Antonio and Austin. Running the roofing and the solar panel work through a single contractor means the sequencing is coordinated from the start and there’s one point of accountability for the whole project.
Things to Sort Out Before Anyone Gets on the Roof
Check your solar system warranty documentation before the project starts. Some manufacturers require removal and reinstallation by a certified installer to keep the warranty valid. Find that out before the job is scheduled, not after.
Tell your roofing contractor about the solar system in the first conversation. The two phases need to be sequenced correctly and if the contractor doesn’t know the array is there going in, coordination issues tend to follow.
Ask specifically how the mounting penetrations will be flashed on the new roof. That detail determines whether those points stay watertight long-term. It should be spelled out in the proposal. If it isn’t mentioned, ask before you sign.
