How to fix roof leak under solar panels

Discovering a roof leak is never a pleasant experience, and when solar panels are involved, the situation can seem even more daunting. While calling in professionals is always the safest and most recommended approach, there may be instances where you feel confident tackling the repair yourself. If you choose this path, proceed with utmost caution and prioritize safety at every step.

Disclaimer: This post is for informational purposes only. Working on roofs and electrical systems poses serious risks. We strongly advise consulting with or hiring qualified professionals for any repairs involving your roof or solar panel system. Proceed at your own risk.

Before You Start:

  • Assess the Situation: Evaluate the severity of the leak, its location, and your comfort level with DIY repairs.
  • Safety First: Prioritize safety by using fall protection equipment, secure ladders, and avoiding working alone.
  • Gather Information: Research your specific roof type, solar panel model, and proper repair techniques.

Step-by-Step Guide

  1. Locate the Leak from Inside
  • Trace Water Stains: Follow the trail of water stains, paint discoloration, or peeling paint on your ceiling and walls back towards their origin.
  • Attic Inspection: Carefully access your attic and use a flashlight to visually inspect the underside of the roof for signs of water or damage. You can also check the attic floor for water stains or wet spots.
  • Focus on Suspect Areas: Pay close attention to areas around penetrations (chimneys, vents, etc.), flashing, and valleys.
  • Rainy Day or Hose Test: If necessary, conduct inspections during rain or perform a controlled hose test to pinpoint the exact location of the leak.
  1. Prepare for Roof Access and Repair
  • Gather Tools and Materials: Assemble all the necessary tools and materials for the repair, including safety gear, roofing materials specific to your roof type, basic tools, and tarps or plastic sheeting to protect surrounding areas.
  • Solar Panel Removal: If solar panels are obstructing the leak area, carefully disconnect and remove them, following manufacturer instructions and safety protocols. If unsure, seek professional assistance.
  1. Access the Roof and Pinpoint the Leak
  • Careful Access: Use a secure ladder to access the roof, ensuring it’s on a stable surface and extends beyond the roofline.
  • Visual Inspection: Once on the roof, carefully inspect the suspected leak area, looking for damaged or missing shingles, cracks, gaps in flashing, or other signs of damage.
  • Probe Gently: If needed, use a flat pry bar to gently lift shingles or flashing to investigate further, being careful not to cause any additional damage.
  1. Repair the Leak
  • Clear Debris: Remove any debris or damaged materials from the leak area.
  • Address Specific Issues: Follow proper repair techniques for your specific roof type and the nature of the damage. This might include replacing damaged shingles, repairing or replacing flashing, sealing cracks or gaps, or addressing valley leaks.
  • Thorough Sealing: Ensure all repairs are properly sealed to prevent future leaks.
  1. Reinstall Solar Panels (If Removed)
  • Careful Reinstallation: Follow manufacturer instructions and safety protocols to reinstall the solar panels securely.
  • Electrical Connections: Ensure all electrical connections are properly made and tightened.
  • Professional Inspection (Recommended): Consider having a qualified electrician inspect the reconnected solar panels for safety.
  1. Post-Repair Cleanup and Monitoring
  • Cleanup: Remove all debris and materials from the roof and surrounding areas.
  • Monitor for Recurrence: Keep a close eye on the repaired area, especially during rainy weather, for any signs of recurring leaks.
