Hail damage on a roof with solar?

If your roof replacement is part of an insurance claim, the detach & reset may be covered as part of the claim, depending on your policy. We'll document the roof and the array so it can be considered. How insurance works with us

The sequencing problem

Your panels will outlast your roof. Plan for that before you install them.

Two service lives that do not line up, and a bill that arrives years later.

A solar array is designed for twenty-five to thirty years. An asphalt shingle roof in Central Texas takes sun, heat, and hail. It realistically lasts fifteen to twenty-five years. Those two numbers do not line up, and the gap between them is where the expense lives. Most homeowners discover this the way everyone discovers roofing problems: a leak appears under an array that still has fifteen good years on it.

The most useful sentence on this page is this one: if your roof is within about five years of the end of its service life, replace it before you install solar, not after. Doing it in that order costs you a roof you were going to buy anyway. Doing it in the other order costs you the roof plus a detach and reset, and it puts your array in storage for several days.

So before you sign a solar contract, have the roof inspected. Get a written estimate of its remaining life. It should note the roof's age, the deck's condition, and any existing damage. That number, not the solar quote, should decide the sequence. We will give you that number through a free inspection, and if the answer is that your roof is fine for another decade, that is what we will write down.

It is worth saying plainly that solar companies are generally not roofing contractors. They are competent at arrays and mostly not in the business of evaluating a roof's remaining life, and the question rarely comes up during a solar sale. That is not usually bad faith. It is simply outside their scope. It is squarely inside ours. If a replacement is close, the cheapest version of this whole project is the one where the roof goes on first.

What detach and reset actually involves

Six stages, two trades, and one detail that determines whether the roof leaks: the mount penetrations.

  1. 1. System shutdown and electrical disconnect

    Our licensed solar team, your solar provider, or a licensed electrician shuts the system down at the inverter and the array. This happens before the roofing crew steps on the roof.

  2. 2. Panel removal and labeled staging

    Panels come off in order and are labeled by position and string so the array goes back exactly as designed. They stay on site when there is safe space. If not, they are transported and stored, which is a real cost line.

  3. 3. Racking and mounting hardware removal

    Rails, clamps, and roof-penetrating feet come off. Rails and clamps are frequently reusable. The feet and their flashings are not, because they were sealed into a roof that is about to be removed.

  4. 4. Roof replacement, with new flashing at every mount penetration

    Tear-off, deck inspection, underlayment, and the new roof go in as normal. The difference: every spot where a mount will land is treated as a penetration detail, not a plain shingle.

  5. 5. Racking reinstalled on new, properly flashed mounts

    New feet, new flashings, integrated into the new shingle courses so water runs over the detail. Old penetrations are not reused and old sealant is not relied on. This step is the whole point of the exercise.

  6. 6. Panel reinstall, reconnection, and commissioning

    Panels return to their labeled positions, our licensed solar team, your solar provider, or an electrician reconnects and commissions the system, and production is verified against expectation before the job is called finished.

The penetrations are the whole point. Every rack foot is a hole through the water plane, and a residential array typically has dozens of them. Reusing old flashing, or sealing a new mount into an old hole, is the same mistake as reusing a skylight flashing kit. It holds for a few seasons, and then it fails. New mounts, new flashings, woven into the new shingle courses. There is no shortcut that is still a roof.

Who does what

One call, one schedule, clear roles.

You make one call. We build the schedule: our licensed solar team or your solar provider for shutdown, detach and reconnection, our roofing crew for the roof and every mount penetration. Nobody stands on a torn-off roof waiting for someone else to show up.

We have our own licensed solar team. You can see how it went on a real job: the North Shearer Hills project.

The electrical side, meaning shutdown, disconnection at the inverter and array, reconnection, commissioning, and production verification, is handled by our licensed solar team, your solar provider, or a licensed electrician. Our roofing crew handles the roof and the mount flashing, not the electrical work.

Which brings up the warranty question. If your system is still under warranty, the original installer or their authorized partner should usually do the detach and reset. Unauthorized handling can void coverage on panels, inverters, or workmanship. If it is out of warranty, our licensed solar team can handle it. That is not a detail to discover afterward.

Planning solar on a metal roof?

If a new roof is on the table before solar goes up, standing seam metal changes the math.

What it costs

Priced per panel, and it adds meaningfully to a roof replacement.

We quote detach and reset per panel, usually about $250 to $350 per panel. A single-panel detach and reset has a $250 minimum. Every job includes calibration and cleanup. A typical residential array of twenty to thirty panels therefore adds several thousand dollars to a roof replacement, and a large array can add considerably more.

Four things move that number. Panel count is the obvious one. Roof pitch and access matter because a steep or hard-to-reach slope slows every stage. Staging matters. Safe space on site keeps cost lower. If panels must be transported and stored, that adds handling and storage. And the condition of the racking matters, since reusable rails cost less than a full hardware replacement, though the roof-penetrating feet and flashings are replaced regardless.

Detach & reset is quoted as its own line item on your written roof proposal, so there are no surprise fees later. For how the underlying roof project is priced, see roof costs.

Solar and roofing FAQs

For a full replacement, generally no. The array sits directly over the deck being torn off, and the racking is bolted through the water plane we are rebuilding. Working around panels leaves old shingles, underlayment, and mount flashing under the array. That is the part of the roof most likely to leak. A partial replacement that skips the solar area is not a full replacement, and it typically won't qualify for a manufacturer system warranty.

We price it per panel, usually about $250 to $350 per panel. A single-panel detach and reset has a $250 minimum. On a typical residential array of twenty to thirty panels that is several thousand dollars added to the roof project. The drivers are panel count, roof pitch and access, whether the panels can be staged on site or have to be transported and stored, and whether the existing racking is in reusable condition.

It can, and this is the single most important thing to check before scheduling. Many solar warranties require that authorized personnel handle the array, and unauthorized removal or reinstallation can void product or workmanship coverage. If your system is still under warranty, the original installer or their authorized service partner should perform the detach and reset. Read the warranty document before anyone touches the panels.

Usually the duration of the roof work plus a day on either side, so for most residential replacements roughly three to seven days. The system is shut down before removal and stays down until reconnection and commissioning are complete. You are on grid power for that period, and you lose whatever production the array would have generated, which on most homes is a modest one-time cost rather than a significant one.

Our licensed solar team, your solar provider, or a licensed electrician. Our roofing crew does not do the shutdown, the DC and AC disconnections, reconnection, or commissioning. If your system is under warranty, the original installer should usually handle it.

No. Every rack foot is a hole through the roof's water plane, and the flashing at that hole is consumed by its original installation. Lifting an old flashing and setting it back down on a new roof, or sealing over an old penetration with caulk, is the same mistake as reusing a skylight flashing kit. New mounts get new flashings, properly integrated into the new shingle courses. Racking rails themselves are often reusable; the roof-penetrating hardware is not.

If the roof has less than about five years of service life left, yes, without hesitation. Panels last twenty-five to thirty years. An asphalt roof in Central Texas lasts fifteen to twenty-five. Putting panels on an aging roof almost always means a detach and reset within a few years. Get a written remaining-service-life estimate before you sign a solar contract. The detach and reset cost is avoided entirely by replacing the roof before the panels go up.

A repair away from the array usually requires no panel work at all. A repair underneath or immediately adjacent to the array may require detaching a small number of panels, which is far cheaper than a full detach and reset. The honest answer in many cases is that a targeted repair buys you several more years before the array has to come off, and if that is the situation we will tell you.

Yes. Leased systems and power purchase agreements are typically owned and serviced by the provider, not by you, and the agreement usually requires their involvement in any removal. Providers often charge their own detach and reset fee and schedule it on their timeline, which can add weeks. Pull out the agreement and call the provider before you set a roof date.

Yes, and when you know solar is coming it is the right move. While the deck is open, we can set flashed mounts or prep the areas where the array will land. That is far cheaper and more watertight than cutting into a finished roof later.

Solar attic fans are their own penetration and get removed, reflashed, and reset like any other roof-mounted unit. Panels that crowd a skylight or a vent are a design problem worth revisiting at reinstall, because a detail you cannot reach is a detail nobody inspects. If the layout leaves no service access to a penetration, we will raise it before the panels go back on.

It should not be, provided the array goes back at the same orientation and tilt and the system is properly commissioned. Ask for a production verification after reconnection and compare the first full month against the same month in prior years. A meaningful drop usually points to a string or connector issue at reinstall, and it is much easier to resolve immediately than a year later.
