Can Water Damage Affect Solar Panels Installed on a Roof?

Solar panels are built to shed rain, but the roof penetrations where they attach are vulnerable. Each mounting bracket requires holes in your roof, and those holes are sealed with flashing and sealant. Over time, that sealant can crack, or the flashing can pull away, especially after heavy storms or temperature swings.

Water can also enter around the panels themselves if the racking system shifts. Wind, ice, or settling can loosen the hardware, creating gaps. Once water finds a path, it can travel along the roof deck and down into your attic or walls, often without you noticing until damage is visible inside.

Start with a roofer to inspect the roof and the flashing around the solar mounts. They can often re-seal or replace damaged flashing. If water has already gotten inside, you will also need water damage pros to dry the affected areas and assess the extent of the damage.

The pros can remove wet drywall, dry out the framing, and check for mold growth. They can also document the damage for your insurance claim. If you live in Cincinnati, keep the contact information for a local roof repair service handy.

• Check your attic for wet insulation or stains after heavy rain
• Look for rust or corrosion on the solar panel racking
• Listen for dripping sounds in the walls or ceiling
• Feel the ceiling for soft spots or sagging
• Monitor your electricity bill for sudden changes
• Take photos of any visible damage for your records

Water damage from a roof leak is typically covered by a standard homeowners policy, but solar panel damage may be treated differently depending on how the panels are mounted and whether they are owned or leased. Check your policy to see what is included and what the deductible is.

Policies vary, and your insurer decides what is covered. Take photos, keep receipts for any temporary repairs, and document everything. If you need help, the water damage pros can provide a detailed report of the damage for your claim.
