Path-Q Solar

What roof inspection should be completed before mounting solar panels?

Answer

The roof should be inspected for remaining service life, leaks, moisture damage, deterioration, attachment locations, and structural capacity before the solar design is finalized. A roofing professional and, when needed, a structural professional should identify conditions that could affect installation.

Key points

  • The inspection should cover roofing materials, flashing, penetrations, sheathing, and visible framing conditions.
  • The roof must be able to support the system and transfer attachment forces safely.
  • The inspection should identify whether repairs or replacement should occur before solar installation.

What it depends on

  • Roof type, age, and accessibility
  • Proposed attachment locations and system weight
  • Visible or reported leaks and prior repairs
  • Whether structural drawings or previous inspection records exist

Risks and trade-offs

  • A limited visual review may miss concealed moisture or framing problems.
  • Repairing the roof after installation may require panel removal.
  • Overly broad repairs may add cost, but inadequate inspection can create larger risks.

Information you may need

  • Roof age and maintenance history
  • Leak, repair, and insurance-claim history
  • Roof plans or structural documents
  • Proposed solar equipment and attachment layout
