Path-Q Solar
Should I repair roof leaks before getting solar panels?
Answer
Yes. Active leaks and known roof defects should generally be diagnosed and repaired before solar installation, because panels and mounting can make later roof work more difficult and costly. The roof should have enough remaining service life to justify installing the array.
Key points
- Identify whether the leak is localized or evidence of broader roof failure.
- Coordinate roof repairs, replacement, flashing, and solar mounting so warranties and responsibilities are clear.
- Obtain written confirmation of what roof work is included or excluded from the solar proposal.
What it depends on
- Cause and extent of the leak
- Roof material, age, warranty, and expected remaining life
- Whether the repair affects planned panel locations or mounting points
Risks and trade-offs
- Installing over unresolved defects can cause property damage and later removal or reinstallation costs.
- A patch may be economical for a localized issue but inadequate if the roof is near replacement.
- Roof and solar warranties may conflict if work is performed by different parties.
Information you may need
- Roof inspection and leak diagnosis
- Roof age, material, warranty, and repair history
- Solar installer and roofer responsibilities, warranties, and exclusions
Your next step
What to do next
Arrange a roof inspection, complete necessary repairs or replacement, and obtain a revised solar design after the roof condition is documented.
