Homeowners in the Charlotte, NC area are increasingly asking about solar panel roof leaks—especially when it’s time for a roof replacement. While solar energy has its advantages, systems installed on asphalt shingle roofs can create challenges that many homeowners don’t anticipate.
We recently completed a project in the Charlotte area where a homeowner chose to remove their solar panel system during a roof replacement after dealing with ongoing leaks. Here’s what we learned—and what you should know.
What Causes Solar Panel Roof Leaks?
Solar panels themselves don’t cause leaks—but the way they are installed can.
Most systems are mounted using mechanical fasteners that penetrate through shingles and into the roof structure. These penetrations rely on flashing and sealants to keep water out. Generally speaking, those materials can wear out more rapidly than the shingles themselves.
Common causes of solar-related roof leaks include:
- Deterioration of sealants around mounting brackets
- Improper or aging flashing details
- Movement or shifting of the panel system over time
- Repeated expansion and contraction from daily temperature fluctuations
Once water gets past these points, it can travel under shingles and show up inside the home.
A Hidden Issue: Debris Buildup Under Solar Panels
One issue that often goes unnoticed is debris accumulation beneath solar panels.
Because panels sit above the roof surface, they can create areas where:
- Leaves, pine needles, and debris collect
- Moisture is trapped and slow to dry
- Organic material breaks down over time
This buildup can:
- Hold moisture against the roof surface
- Accelerate shingle deterioration
- Increase the likelihood of leaks in vulnerable areas
On our recent project, we found significant debris accumulation under the panel system, contributing to long-term moisture exposure.
How We Remove Solar Panels for Roof Replacement
Removing a solar system requires careful coordination—it’s more than just a roofing job.
A proper decommissioning typically involves:
- A licensed electrician to safely disconnect the system
- A roofing contractor to repair penetrations and replace materials
- A recycling or reuse partner to handle the panels responsibly
In this case, we worked hand-in-hand with both an electrician and a recycling team to ensure the system was removed safely and that the panels were repurposed instead of sent to a landfill.
Common Roof Issues Related to Solar Installs
In the Charlotte and NC Piedmont region, we frequently encounter:
- Leaks around mounting points
- Sealant breakdown over time
- Difficult access for roof repairs beneath panels
- Complications during roof replacement projects
- Debris and moisture buildup under panels
Many homes simply were not designed with these systems in mind.
Do Solar Panels Void Your Roof Warranty?
This is an important question. And the short answer is, yes. Adding penetrations to a roof system void both manufacturer and workmanship warranties – unless the solar is installed by your roofing installer.
A Roofing Perspective: We Never Recommend Poking Holes in Your Roof
At Blue Fox Roofing, our priority is protecting the integrity of the roof system.
A properly installed roof is designed to shed water naturally. When holes are introduced—no matter how well sealed—the roof system becomes dependent on the long-term maintenance of sealant, rather than working the way it was designed.
That doesn’t mean solar can’t work—but it does mean homeowners should understand the trade-offs.
A Better Outcome for This Homeowner
By removing the solar panel system, we were able to:
- Install a complete, uninterrupted roofing system
- Eliminate chronic leak issues
- Replace rotten roof decking so the new roof has a secure nailing surface
- Restore confidence in the home’s protection
And importantly, we ensured the panels were handled responsibly through recycling and reuse efforts.
Final Thoughts
Solar energy can be a great solution in the right situation—but when installed on a shingle roof, it’s important to understand how it interacts with your roofing system.
If you’re dealing with solar panel roof leaks in Charlotte NC, or considering a roof replacement with an existing solar system, it’s worth getting an experienced perspective.
