Do Solar Panels Void Roof Warranty?

Solar Panels Void Roof Warranty

Solar panels have become increasingly popular among homeowners, and for a good reason. Installing solar panels reduces carbon emissions, creates a renewable energy source for a household, lowers electricity bills, and improves a home’s value.

But with this growing popularity comes an increasing concern that has many homeowners asking, “Do solar panels void a roof warranty?”

Unfortunately, the answer isn’t always cut and dried. Generally, solar panels do not void a roof warranty- but in some situations, they can. As such, it’s essential to familiarize yourself with roof and solar warranties to determine if adding solar panels to your home will void your existing roof warranty.

What to Know About Roof and Solar Warranties

Your roof system is your home’s first line of defense against the elements, costly water damage, and critter invasions. Properly installed solar panels should not undermine a roof’s integrity and vice versa. That’s why consulting a reputable professional is vital when considering adding solar panels to your home.

While warranties for roofs can vary widely between companies, at least a basic warranty comes with any legitimate installation. They generally include two core protections:

  • Materials Warranty: Part of your roof’s warranty covers production defects in the roofing material. Various material types have varying lengths of coverage. For example, a metal roof typically has a more extended warranty than an asphalt one. However, this warranty does not usually cover normal wear and tear or installation-related damages.
  • Workmanship Warranty: Reputable roofing contractors stand by their work, and it’s common for roofing warranties to include a workmanship warranty covering labor and installation.

Solar panel warranties work a bit differently than roof ones. Not only do they generally include a product warranty and workmanship warranty, but they usually include a warranty for their performance. These warranties ensure the solar panels provide a minimum amount of energy production over a set period.

So, do solar panels void a roof warranty? Usually, no, because they cover different problems and don’t replace one another.

When Solar Panels Will Void Roof Warranty

So when do solar panels void a roof warranty? When solar panels are installed, the solar company adds other roofing elements and features to an existing roof. These added features will usually not be covered by the original roof warranty. So, for example, if a solar panel was improperly installed and caused damage to a roof, that damage may not be covered under your roof’s warranty.

Additionally, some roofing companies will void a roof warranty if a third party, including a solar panel company, alters any portion of the roof.

Ways to Prevent Voiding a Roof Warranty with a Solar Panel Installation

No one wants to void their roof warranty, especially if you still have plenty of years on it. One of the easiest ways to find out if installing solar panels will void a roof warranty is by contacting the company that installed your roof.

Alternatively, you may want to consider a roof replacement before installing solar panels so you can use a roofing company that performs both installations or to ensure your warranty periods will be more aligned. For example, if you install solar panels and need to replace your roof a few years later, those panels may need to be moved, and you could risk voiding your solar panel warranty. 

Solar Panel Installation Considerations

Any damage to your roof caused by solar panels is most likely to occur during installation. Improper installation voids your roof warranty and exposes your home to severe water damage. Therefore, always hire professional solar contractors who use the correct forms of flashing and sealants during installation.

Will Solar Panels Void Your Roof Warranty?

So will solar panels void your roof warranty? Maybe. When in doubt, it’s always best to check with a trustworthy roofing company to better understand your particular warranty details.

Doing so before a solar panel installation will help you make an informed decision about your options, assess your roof’s current condition, and provide you with peace of mind for many years to come.
