The Hidden Risk: Roof Leaks from Improperly Installed Solar Panels

The push for renewable energy has led to a surge in solar panel installations across the country, especially in SoCal. While solar panels can provide homeowners and commercial businesses with significant energy savings and environmental benefits, they can also pose a serious risk to your roof and home if not installed correctly. One of the most common issues we see as roofing professionals is roof leaks caused by improper solar panel installation.

How Improper Solar Panel Installation Causes Leaks

Solar panels are typically mounted onto your roof using brackets that must be properly secured and sealed to prevent water infiltration. If the installation team lacks roofing expertise, they may inadvertently compromise the roof’s integrity, leading to leaks. Here are some of the most common mistakes that result in roof leaks:

1. Poorly Sealed Mounting Points – The brackets securing solar panels must be properly sealed with flashing and waterproofing materials. If these points are not sealed correctly, water can seep into the openings, causing damage over time.
2. Drilling Errors – Installers must be precise when drilling into the roof to secure mounting hardware. Incorrectly placed holes or excessive drilling can create weak points where water can enter.
3. Lack of Proper Flashing – Flashing is a critical component of any roofing system, especially where penetrations occur. Some installers may skip or improperly install flashing around the mounts, leading to water intrusion.
4. Damaged or Removed Shingles – Inexperienced solar installers may remove or damage shingles while mounting panels, leaving exposed areas where water can seep in.
5. Poor Drainage Planning – Solar panels alter the way water flows off your roof. If panels are installed in a way that traps water or directs it toward vulnerable areas, leaks and water damage can occur over time.

Signs That Your Solar Panels May Be Causing Roof Leaks

If you have solar panels installed, be on the lookout for these warning signs of roof leaks:

• Water stains on your ceiling or walls
• Mold or mildew growth in your attic
• Dripping water or damp spots after rain
• Unusual musty odors in your home

Ignoring these signs can lead to serious structural damage, mold growth, and costly repairs. If you suspect your solar panels may be causing a leak, it’s best to act quickly.

How to Prevent Roof Leaks from Solar Panels

To ensure your solar panels don’t lead to leaks, consider the following best practices:

• Choose a Qualified Installer – Work with a reputable solar company that has experience coordinating with roofing professionals.
• Conduct a Roof Inspection First – Have a roofing expert inspect your roof before installation to ensure it’s in good condition and capable of supporting solar panels.
• Use Proper Mounting and Sealing Techniques – Confirm that installers use high-quality flashing, sealants, and mounting methods designed to prevent leaks.
• Schedule Regular Inspections – Even after installation, periodic roof inspections can help detect potential issues before they turn into costly problems.
