If you need a new roof after installing solar panels, the panels have to come off first. A crew removes them, the roof gets replaced, then the panels go back up and are reconnected. It works, but it adds cost and time, which is why it's best to start with a roof that will last as long as your solar.
This is one of the most common worries we hear from Massachusetts homeowners, and it's a big reason people hold off on solar. Here's how it works and how to avoid it.
What happens step by step?
- The system is shut down safely. Solar panels make power whenever the sun is out, so this step matters.
- The panels and racking come off. They're stored, usually on site, while the roof is done.
- The roof gets replaced. The roofer does the work like any other roof job.
- The panels go back up. The racking is reattached, the panels go back on and everything is reconnected and tested.
Depending on your town, a permit or inspection may be needed for the work too.
How much does it cost to remove and reinstall solar panels?
It depends on the size of the system and your roof, but it often runs several thousand dollars on top of the roof itself. You may also lose some solar production while the panels are off. That's money a new roof up front would have saved you.
Who does the work?
Usually a solar crew takes the panels off and puts them back on, and the roofer handles the roof. If you have a solar lease or PPA, read your contract first. It may say who has to do the removal, and the solar company may need to be part of it.
What about roof repairs, not a full replacement?
Small repairs can sometimes be done around the panels. A few panels may need to come off to reach the spot. Bigger repairs, or anything right under the array, usually means removing more of the system.

The easiest way is to start right. If your roof is 15 years old or older, replace it before the panels go up. That way your roof and solar can go the distance together.
Knowing how long a roof lasts in Massachusetts makes it easier to decide whether to replace your roof before installing solar panels.
For Massachusetts homes that qualify, a new roof can be included when you go solar, with no upfront cost. That's a big reason solar companies include new roofs in the first place, and why so many homeowners choose to get a new roof with solar panels in one project.
