A roof leak after solar panels is usually at a mounting point: every bracket is bolted through the roof, and each needs proper flashing. Other common causes are unsealed wiring penetrations and damage from walking on the roof during installation. Start with the solar installer's warranty, and get an independent leak check if needed. We trace these the same way as any roof leak repair.
Where solar panel roof leaks come from
- Mount flashing. Brackets bolted through shingles without proper flashing, or with sealant only.
- Missed rafters. Bolts that missed the rafter and only hold the decking, then work loose.
- Conduit and wiring penetrations not booted or sealed.
- Installation damage. Cracked tiles or broken shingle seals from foot traffic.
- Debris under panels. Leaves trapped under the array dam water.
What to do about a roof leak after solar panels
- Photograph itinside and note when it leaks.
- Call the solar installer first.Their warranty usually covers their roof penetrations.
- Get an independent checkif they say it's the roof. We trace the water from the attic to the exact entry point.
- Coordinate the repair.Some fixes need panels lifted; that's usually the solar company's job.
Before you install solar
Check how much life the roof has left: see how long roofs last in Florida. If the roof is close to replacement, re-roof first. Tile roofs need tile-specific mounts and careful work: see tile roof leak repair. Check whether your roof warranty survives other trades' penetrations: see roof repair warranty. A roof leak after solar panels is usually fixable without removing the whole array.
Solar roof leak questions
Why did my roof start leaking after solar panels?
Every mounting bracket is fastened through the roof. If the flashing around a mount isn't installed properly, or wiring penetrations aren't sealed, water gets in.
Who fixes a leak under solar panels?
Start with the solar installer, whose workmanship warranty usually covers their penetrations. A roofer can find and confirm the leak source independently.
Does solar void my roof warranty?
It can, if the roof warranty excludes penetrations by other trades. Check both warranties before installation.
Should I replace my roof before installing solar?
If the roof has less life left than the panels, often yes. Removing and reinstalling panels later adds cost.
Can my HOA ban solar panels?
Florida law (Statute 163.04) generally prevents HOAs from banning solar, though they can set placement rules within limits.
