Solar Panel Detach and Reset for a Texas Roof Replacement

A reroof under solar, a roof replacement in Texas with panels on top, runs in four stages, and the roof work and the electrical work belong to two different licensed trades. Here is the order, and who owns each step.

ARP runs the roofing half and coordinates the calendar with your solar provider, so the panels are down for the shortest window the job allows: one written roof scope, one point of contact holding the schedule together.

Your panels sit on the exact surface a replacement has to reach. An array covers most of a roof plane, and a real replacement is a tear-off: the old roofing comes off to the decking, the deck gets inspected, new underlayment and flashing go down, then the new roof. None of that can happen under a fixed array bolted to the roof you are removing.

There is a safety reason too. A grid-tied system is live whenever the sun is up, so it has to be shut down and disconnected by someone qualified before anyone works around it. And the mounts holding your panels are holes drilled through the roof. Replacing the roof means re-flashing every one of those holes, which you cannot do with the panels still loaded on top of them. That is why "just roof around them" is never the honest answer.

The roof under a solar array is the one part nobody has looked at in years. When we pull the panels, that's the moment to fix what's under them, because getting back up there after reset is the expensive way to do it twice.

Here it is plainly: ARP is your roofer, not your electrician. The disconnect, the panel removal, the remount, and the reconnection are electrical work, performed by a licensed solar or electrical contractor: sometimes the company that installed your system, sometimes a qualified partner we coordinate with on your behalf. ARP does not perform the electrical scope, and you should be wary of any roofer who says they will.

What ARP owns is the roof and the weatherproofing: the tear-off, the decking, the new underlayment, and re-flashing every mount penetration so the array comes back down onto a watertight roof. Keeping the electrical work with a qualified solar contractor also protects you on paper: many panel and inverter warranties are voided the moment an unqualified party moves the equipment. That clean handoff between the two trades is the whole job.

This is the question that should keep you up at night, and the answer is entirely about the reset. Every foot of your racking is an anchor drilled into the roof. Done wrong, a reset just bolts the panels back through fresh roofing with tired hardware and old sealant, and you have bought a new roof with a dozen future leaks pre-installed.

Done right, each mount lands in new flashing, sealed into the new roof the way a plumbing vent or a skylight would be, not caulked over and hoped for. Where the original layout put anchors in weak spots, the rail positions can often be adjusted to land on solid framing. A reset is not "put the panels back." It is re-flashing your roof one penetration at a time.

Detach and reset is a real, separate line item on a replacement, and you deserve to see it as its own number rather than have it folded quietly into the roofing price. What it runs on your home depends on a handful of honest drivers: how many panels you have, the racking type (rail versus rail-less, penetrating versus ballasted), your roof pitch and how easy the array is to reach, and whether your original installer's mounting hardware can be reused or has to be replaced.

Because those drivers only reveal themselves when someone is standing at your array, we give you that figure in writing after we assess it, not as a guess over the phone. You will see the roof side and the detach-reset side laid out separately. For the roofing half of the math, the full roof replacement cost breakdown walks through what moves your number.

Shorter than most people fear. In a typical job the panels come off the morning the roof starts, the replacement goes on in the usual one-to-three-day window, and the reset and re-commission follow once the new roof passes its final check. Your array is offline while it is down, so a grid-tied system stops producing for those few days. If you are on net metering, time the work with your billing cycle in mind.

What makes or breaks the timeline is coordination, not labor. Two trades have to hit the same roof in the right order without stepping on each other, and that only works when one schedule holds both. ARP keeps that schedule and stays your point of contact for the roofing side from tear-off through the mounts going back down. You can see how the roofing portion runs, step by step, on the roof replacement process page.

With panels on the roof you're really hiring two trades to cooperate. We plan the detach and the reset as one job, so nobody points fingers when the roof and the power bill both have to work.

We would rather be honest about this here than at your kitchen table.
