How to Replace a Roof with Solar Panels

Owens Corning

What happens if you need to replace your roof- but you also have solar panels? No problem! This is not too uncommon a scenario, actually. The lifetime of solar panels is usually 20-25 years, but they can last far longer than that, sometimes outliving the roof they were first installed on! Many people have also moved and brought their solar panels with them. They’ve all asked this question before.

The answer is simpler than you might think.

Step 1

First things first, call the solar company who installed your panels.
If you purchased your solar panel system with Sunpro Solar, all you need to do is call up your consultant. They will take it from there.
If your solar panels were not originally installed by Sunpro Solar, don’t worry. Our expert consultants can help you with whatever procedures you may need for removal.

Step 2

Your consultant will handle getting a crew out to safely remove your solar panels.
If you can, have your original solar company handle your solar panels. That way you will avoid accidentally damaging your panels, or voiding any warranties.
Again, if your original solar installers are not an option, Sunpro Solar can handle any procedures needed for this.

Step 3

Once uninstalled, your panels should be placed in a secure spot away from all the activity.
A garage or shed is usually acceptable. You should not leave them outside on your porch or front lawn.

Step 4

Your roof installers will begin the process of first removing your old roof.
This causes a lot of debris, which is why you don’t want your solar panels sitting outside.

Step 5

Once your old roof is removed, the installers will begin the re-roofing process.
The amount of time it takes to replace a roof varies depending on the size of your roof. Your roofing company will be able to tell you how long it should take.
Some factors, such as if you’re switching from shingle roofing to metal roofing, can also have an impact on how long the roof replacement will take.

Step 6

When the new roof installation is complete, and the roofing company has cleaned up and cleared out, your solar installers will take your solar panels and reinstall them on your roof.
This also includes reconnecting your solar panels up to your utility grid, and to your solar batteries if you have them.

And there you have it! Aside from the amount of time it takes, installing a new roof when you have solar panels is pretty painless. But if possible, it is best to replace your roof before going solar. That way, you can more easily avoid having to install, uninstall, and then reinstall your solar panels. It saves time, and is more cost-efficient.

You may also be asking how much this removal and reinstallation may cost. The truth is, it really depends on a few different things. The size of your solar panel system is a factor, of course. And if you decide to switch from an asphalt roof to a metal roof, that can make a difference also. However, your Sunpro Solar consultant will discuss all these factors with you prior to your roof replacement taking place.
