⚠️ Inspector’s Warning: What You Need to Know About Solar Panels and Roof Damage
Our inspector found this serious installation error — the solar company cut down a plumbing vent to make room for their panels (photo above). This modification violates building standards and can lead to roof leaks, poor ventilation, and even sewer gas entering the home. Always have your roof and solar installation inspected to ensure your home stays safe and code-compliant.
Solar Panels: Great Idea, Poor Execution
Across Central Texas, more homeowners are turning to solar energy — and it’s easy to see why. Lower utility bills, energy independence, and eco-friendly living are all strong selling points.
But as home inspectors, we’ve seen what happens when solar panels are installed incorrectly. Roofs are one of the most critical systems in a home, and unfortunately, poor solar installation can compromise that system in ways most homeowners never realize until it’s too late.
The Hidden Problems We Find Under Solar Panels
Solar panels themselves aren’t the problem — improper installation is. Here are some of the most common issues our inspectors uncover:
- Roof Damage: Installers sometimes drill directly through shingles or flashing without proper sealing. Over time, those penetrations allow water intrusion and rot.
- Obstructed or Altered Vents: Like in the photo above, we’ve found plumbing vents cut down or blocked entirely to make panels fit. This violates code and can cause sewer gases to back up into the home.
- Pest Intrusion: Gaps beneath panels make perfect nesting spots for birds and squirrels, which can chew wiring or clog drainage areas.
- Trapped Heat and Moisture: Poor clearance or airflow design can lead to excessive attic heat and accelerated roof deterioration.
💬 “It’s not uncommon for us to find active roof leaks, damaged flashing, or improper vent modifications hidden beneath solar arrays.”
Buying a Home with Solar Panels Installed?
If you’re considering buying a home that already has solar panels, here’s what you should know:
A standard roof inspection might not cover what’s beneath or around solar panels. That’s why our inspection process includes:
- Checking mounting and flashing integrity to ensure watertight seals.
- Verifying that plumbing and exhaust vents are unaltered and functioning.
- Assessing the condition of roofing materials beneath panel mounts.
- Evaluating solar system age and maintenance records for safety and efficiency.
💬 “Our goal is simple — to help you buy with confidence, knowing your home’s roof and solar system are both safe and compliant.”
For Homeowners Installing Solar Panels
If you’re planning to install solar panels, a few preventive steps can potentially save you thousands in future repairs:
- Get a Roof Inspection First.
Your roof should be in good condition before panels go on — otherwise, you may trap existing issues underneath. - Hire Certified Installers.
Always verify that your installer uses proper flashing and follows roofing manufacturer guidelines. - Add Pest and Vent Guards.
A simple mesh barrier can prevent birds and debris from collecting under panels. - Schedule Post-Installation Inspections.
Have a licensed home inspector review the roof and panel mounts once installation is complete.
