Hi, I’m Danny Dearing. As a passionate home improvement enthusiast with years of hands-on experience, I aim to assist you in resolving those stubborn roofing issues efficiently. Let’s dive right in and get started! ²

Key Takeaways

• Inspect Panels and Roof: Look for cracks, gaps, or loose shingles around the panels. Check screws and bolts to prevent leaks.
• Use Proper Tools and Materials: Have caulk, flashing, and sealant ready. Replace damaged parts to keep water out.
• Perform Water Tests: Spray water to find leak sources. Mark any wet areas found inside for repairs.
• Temporary Panel Removal: Sometimes remove panels to fix underlying roof issues. Get help from a certified solar installer if needed.
• Adjust Panel Positioning: Tilt panels properly to direct water away and ensure good drainage by spacing them evenly.

Inspect the Installation and Condition of Solar Panels

I always start by checking the seals and flashing around my solar panels. Any cracks or gaps can let water in. I look for loose, damaged, or missing shingles, too. These can cause leaks under the solar array. ¹

Using a flashlight helps spot moisture signs underneath. If there are wet spots, corrosion might be present on metal parts like panel mounting brackets or racks. It’s crucial to check all screws and bolts—loose fasteners can lead to bigger issues later! ²

Key Repair Strategies

It’s crucial to have the right tools and materials to fix roof leaks—like caulk, flashing, and sealant. These basic repair strategies can save your home from serious damage….

Check and Replace Flashing and Seals

Fixing roof leaks under solar panels can be tricky. You must check and replace the flashing and seals to ensure no water gets in. ³

1. Examine Flashing Around Mounts
   • Look at the flashing around where the panels attach.
   • Ensure it covers the shingles properly.

2. Inspect for Deterioration
   • Check caulk and rubber sealants.
   • Find any cracks or worn parts.

3. Remove Old Sealant
   • Use a putty knife to scrape off damaged caulk.
   • Be careful not to damage the roof surface.

4. Apply New Sealant
   • Choose quality sealants like polyurethane or flexible silicone.
   • Apply around the mounts, flashings, and any gaps found. ¹

5. Replace Damaged Flashing
   • If flashing has rust or is bent, replace it.
   • Install new pieces so they overlap shingles.

6. Tighten Screws and Bolts
   • Make sure all mounting hardware is tight.
   • Loose screws can let water in.

7. Perform Water Tests
   • Spray water over the solar panel area with a hose.
   • Check inside for any leaks during this test.

By following these steps, you can diagnose and fix leaks under your solar panels efficiently.

Perform Water Tests to Identify Leaks

Next, let’s perform water tests to identify leaks. These tests help you find where the water comes in. ⁵

1. Pick a dry day.
2. Use a garden hose to spray water around the panels.
3. Focus on flashing and joints.
4. Wait for about 5-10 minutes.
5. Go inside and look for drips or wet spots.
6. Mark any areas with leaks using tape or a marker.
7. For non-invasive detection, use infrared thermography tools. ⁴
8. Try electrical impedance testing to check insulation resistance.

These steps help locate the source of roof leaks under solar panels effectively and efficiently.
