Installing Solar Panels Without Voiding Your Roof Warranty

If you're a Southern California homeowner planning to put on a new roof — or already have solar panels and need a roof replacement — you're probably asking: “Will the solar installation or reinstallation void my roof warranty?” That’s a totally valid concern. Between the cost of a high-quality roof in SoCal and the investment in solar, the last thing you want is to jeopardize either one.

Leaks, improper flashing, or screw penetrations can lead to finger-pointing between your roofer and solar installer if something goes wrong. On top of that, many homeowners worry: “If they remove my panels to redo the roof, will that void my warranty too?” The good news is: not always — but it depends on the details.

At US Power, we understand how critical this is. Through our exclusive, factory-direct partnership with QCells, we make sure that when we remove and reinstall your solar panels — or when we install them for the first time — your roof warranty is protected as much as possible. We work closely with roofing contractors, use certified mounting hardware, and follow best practices to minimize risk.

Understanding Roof Warranties & How Solar Might Impact Them

What Is a Roof Warranty, Anyway?

A roof warranty typically has two parts:

• Manufacturer Warranty — This covers the materials (shingles, tiles, etc.) for a certain number of years.
• Workmanship Warranty — This is provided by your roofer, covering how well they installed the roofing system.

When solar is installed, especially through roof penetrations (mounts screwed in), there’s a risk that flashing, seams, or the shingles themselves could be disturbed, which raises concerns about whether the warranty remains valid.

What Roofing Manufacturers Actually Say About Solar

Not all roofing manufacturers are against solar. For example, GAF — a major shingle maker — has a technical bulletin stating that solar PV panels do not void their limited shingle warranty.

However, that same bulletin notes: if there's a problem with the shingles, it's the homeowner’s responsibility to remove the solar panels at their own cost so GAF can inspect and repair affected shingles.

So, while solar doesn’t automatically void the warranty in some cases, you must be prepared for the logistics if a repair is needed — and ensure the installation was done correctly from the start.

Does Installing Solar Automatically Void Your Roof Warranty?

Short answer: No, not necessarily. But it strongly depends on how the work is done, who does it, and what your specific roof warranty says.

Here’s what homeowners and solar professionals commonly report:

One Reddit user noted:

“Just the fact of adding solar does not void roof warranties … Cover your ass by having a LICENSED AND INSURED SOLAR COMPANY remove and re‑install your panels.”
Reddit

A solar contractor added:

“They will not just ‘take over the roof warranty’ … It depends on your own warranty … some [roof warranties] will have guidelines … if it needs to be through an installer they approve of.”
Reddit

Another homeowner shared that their roofer actually sent an inspector after the solar install to verify that no improper holes or damage were made, ensuring the 50-year roof warranty remained valid.

In short, the risk is real — but it's not insurmountable with the right planning. Learn more about solar panel removal and reinstall tips for LA homes to protect your warranty.

How to Protect Your Roof Warranty When Adding or Reinstalling Solar

To make sure solar doesn’t jeopardize your roof warranty, here are proven strategies — especially relevant for SoCal homeowners:

Review Your Roof Warranty Carefully

Before you commit, ask to see the actual warranty document. Different manufacturers and roofers will have different terms.

Clarify whether there are restrictions on penetrations or whether only certain mounting methods are allowed. You may also check California roof compatibility guide for solar panels to ensure your roof type is supported.

Work with Certified Installers

Use licensed and insured solar and roofing contractors. This is crucial.

Make sure your roofer and solar installer coordinate before work begins. They should inspect together and plan where mounts will go.

Use Proper Mounting Hardware

Use flashings and mounts that are compatible with your type of roofing (shingles, tiles, metal, etc.).

Ask your solar contractor to follow manufacturer-recommended installation methods to reduce risk of leaks.

Post-Installation Inspection

After solar installation (or reinstallation), bring in an inspector (roofing manufacturer–approved, if possible) to check that the work was done correctly.

Document everything with photos before and after install/roof work — this helps in case of future warranty claims.

Contract Scope of Work

Make sure the contract for removal/reinstallation clearly states who will handle what: who removes the panels, who repairs the roof, who puts the panels back, and who inspects.

Include warranty preservation in that agreement.

Plan Ahead for Reinstallation

If you're replacing the roof and already have solar, plan for the removal and reinstall from the start — don’t treat them as separate, unrelated jobs.

Ask your installer to provide a detailed removal/reinstall plan that minimizes risk to the roof.

Real Risks and Real-World Examples

Here are some pitfalls and lessons drawn from real homeowner experiences — especially relevant to retrofit solar and roof replacement:

A concrete-tile roof owner reported a leak after reinstalling solar, and discovered flashing had a slit. The roofer accepted responsibility, but only after both roofer and solar company were called out.
Reddit

Another homeowner had to pay an extra $200 for their roofer to send an inspector after solar installation just to verify no warranty issues would arise.
Reddit

On the flip side, some installers are very cautious and will only work with solar-certified roofers to avoid voiding warranty coverage.
Reddit

These examples underscore how critical it is to proactively plan for both roof and solar. Learn how to choose the best solar company in Los Angeles for proper installation and warranty protection.

• Transparent Contracts: Our scopes of work explicitly cover removal/reinstallation, ensuring that every step is documented and planned — not guesswork.

Plus, with QCells panels, you benefit from:

What About Roof Replacement When You Already Have Solar?

If you already have solar panels and need to replace the roof, here’s a step-by-step guide to do it smartly:

• Get Quotes That Include Both Solar and Roofing Work
  Ask your solar company and roofers to bid the entire job together — remove panels, redo roof, reinstall panels — not separately.
• Pre-Job Inspection
  Have both teams inspect the roof before removing anything. Take photos for documentation.
• Temporary Removal & Safe Storage
  Panels should be carefully unmounted, labeled, and stored properly so they aren’t damaged.
• Roof Replacement Work
  The roofer replaces underlayment, flashing, decking, etc. Make sure they follow best practices and coordinate mount locations.
• Reinstallation of Solar
  Use the same or improved mounting hardware. Have your solar installer re-mount the panels, again coordinating with the roofer.
• Final Inspection & Sign-off
  After reinstallation, run a final inspection (and ideally a water test/flash test) to make sure everything is sealed correctly.
• Document Everything
  Keep before & after photos, contractor reports, and inspection notes in a folder — this helps if you ever need to file a warranty claim.
