Do You Need to Remove Solar Panels to Replace a Roof?
Short answer: yes — the panels over the work area have to come off. Here's why, and how it's done without harming your system.
It's one of the most common questions Minnesota homeowners ask us: do the solar panels really have to come off to replace the roof? For the section of roof being worked on, the answer is yes. A roof can't be properly replaced with panels bolted over it. The good news is that removing and reinstalling them — a detach & reset — is a standard, safe process when the right people do it.
Why the panels have to come off
A roof replacement means stripping the old material down to the deck and installing new underlayment and shingles. That can't happen under a mounted array. Panels and racking over the work area must be detached so the roofer can do the job right — with no shortcuts around mounts and no compromised waterproofing.
What about partial roof work?
If only part of the roof is affected, sometimes only the panels over that section need to come off. We assess your specific roof and array to determine whether it's a partial or full detach, so you're not removing more than necessary.
Why you shouldn't DIY it
Panels sit on a live electrical system. Improper handling risks shock, roof damage, cracked panels and voided warranties. Detaching and resetting solar is a job for a qualified solar crew — not a roofer working around them or a weekend project.
How the detach & reset works
The system is safely disconnected, the array is removed and stored, the roof is replaced, and the panels are reinstalled and recommissioned. Sequenced with the roofing, the array's downtime stays short and you end with a new roof and a working system.
Do it once, with the roof
The most economical approach is to time the detach & reset with the roof replacement as a single, coordinated project. Detaching now and resetting weeks later on a separate schedule adds cost. iSolar handles the solar side and coordinates with roofing so it's one clean job.
Protecting your warranty
Done correctly, a detach & reset keeps your equipment and warranties intact. Our crews document and handle components properly and recommission the system so it performs exactly as it did before.
Frequently asked questions
Do solar panels have to be removed to replace a roof?
Yes, for the section being worked on. A roof can't be properly replaced under a mounted array, so the panels over the work area must be detached and later reset.
Can the roofer just work around my panels?
No. Working around mounts compromises the roof and risks the array. Panels should be properly detached by a qualified solar team first.
Can I remove the panels myself to save money?
We strongly advise against it. Panels sit on a live electrical system, and improper handling risks injury, damage and voided warranties.
Do all the panels have to come off?
Not always. For partial roof work, sometimes only panels over that section are removed. We assess your roof and array to remove only what's needed.
Is it cheaper to detach and reset with the reroof?
Yes. Coordinating it as one project avoids extra trips and downtime, so you pay once and the roof and array line up.
