Leak Under Solar Panels: Who Actually Fixes It?

Neither one automatically. The roofer usually cannot start until the panels come off, and removing them is normally the solar company’s job or yours to pay for. Which applies is settled by your solar contract rather than by the trade involved. So the first thing to read is not a repair quote. It is the detach and reset clause in the agreement you signed when the panels went on.

Rancho Roofing is a licensed C-39 contractor in Encinitas, CSLB #1153860. This page explains why the answer is so often unclear, and what to check before the two trades start pointing at each other.

It comes up constantly in coastal North County, where a lot of houses got panels during the same few years and are now reaching the age where the surface underneath needs attention.

If water is coming in right now

Contain the water first: move things clear, put a container down, and photograph the stain before wiping anything. Note when it started and whether it is spreading.

Do not go onto the roof, and do not touch the panels or any wiring. A solar array is live in daylight, and that is a genuine hazard rather than a caution.

Why does nobody want to own the problem?

Because the leak sits at the boundary between two trades, and neither installed the other’s work.

The Solar Cancellation Resource Center’s June 2026 material describes the pattern directly. Leaks under panels create disputes between roofing contractors and solar companies over responsibility. Homeowners often cannot tell whether the water came from ageing material, storm damage, or the installation penetrations themselves.

That last possibility is the awkward one. Panel mounts are bolted through the surface, and each one is a hole that was sealed by whoever installed the array. If a mount is the source, the roofer did not create it and the solar company did not build the roof.

Meanwhile the system keeps generating and the water keeps moving. The same source notes that delays let damage spread underneath while everyone establishes whose problem it is.

What does the contract actually decide?

Almost all of it, and most people have not read that part.

The Solar Cancellation Resource Center’s June 2026 material lists the provisions that matter. Roof maintenance responsibilities, detach and reset obligations, warranty limitations, and service exclusions. Then third-party contractor requirements, liability disclaimers, transfer restrictions, and equipment ownership.

The same source describes a common gap between what people remember being told and what they signed. Homeowners frequently report being assured during the sale that panel removal for future roof work would be free or included, then finding the written agreement says otherwise.

The sentence that decides who pays is in a contract you signed years ago, not in the quote you are about to be given. Find it before you book anything.

What does taking the panels off cost?

Several thousand dollars upward, depending on the size of the system.

The process is called a detach and reset. The Solar Cancellation Resource Center’s June 2026 article puts it at several thousand dollars upward, depending on system size and roof structure. Its headline figure is $5,000.

The steps explain the price: disconnect the system, remove the mounting hardware, store the equipment safely, coordinate with the roofing work, reinstall, then reconnect. It is electrical work as much as it is lifting.

It also has to be done properly. Removal Reinstall’s May 2026 guide notes that a detach and reset done the wrong way can damage panels, create leaks, or void the solar warranty. That is an argument against whoever is cheapest.

What if the original installer has gone?

Then you are looking for a specialist rather than the company you bought from.

The Solar Cancellation Resource Center notes that parts of the residential solar industry have seen closures, mergers, and contractor turnover. That leaves some homeowners with no clear route back to whoever installed their system.

Companies exist that do nothing but detach and reset work for roofing projects, and they coordinate with the roofer rather than competing with them. That is usually the practical answer when the original installer is unreachable.

One thing worth doing while everything is off. If the surface underneath is near the end of its life, replacing it during the same detach is far cheaper. The alternative is paying for a second removal in a few years. More on that in whether to replace before going solar, and we work on roofs with arrays on them on roofs with arrays on them.

Can a roofer work around the panels?

Sometimes, if the leak is well clear of the array and access is possible without disturbing it. Anything under the panels or near a mount usually needs them off. A roofer who offers to work blind under an array is guessing about the source.

Does a leak under panels void anything?

That depends on both agreements, which is the recurring theme. Removal Reinstall’s May 2026 guidance is that a badly executed detach and reset can void the solar warranty. Whether the roofing warranty is affected depends on who installed what and when.

How do I find out if a mount is the source?

Usually only by removing panels in the area and inspecting the penetrations directly. From below, in the attic, the water path can sometimes be traced back to a specific mount location, which narrows where to look before anything comes off.

Should I involve my insurer?

Documentation is worth having either way, so photograph everything before it is touched. Whether a claim applies depends on the cause and the policy language, and gradual wear is excluded on most policies. The California Department of Insurance explains what residential cover does and does not include.
