Path-Q Solar

What next step is appropriate if the installer’s site survey does not address roof drainage?

Answer

Pause approval of the design and request a roof plan showing drainage paths, gutters, downspouts, penetrations, access, and any areas that must remain clear. If the installer cannot competently assess drainage, obtain a separate roof professional's review before proceeding.

Key points

  • Ask how modules, rails, conduits, and attachments avoid blocking water flow or maintenance access.
  • Require the design to address existing drainage defects rather than assuming installation will not affect them.
  • Clarify responsibility for leaks, ponding, blocked gutters, and damage caused by installation.
  • Do not treat a generic statement that drainage will be preserved as a site-specific assessment.

What it depends on

  • Roof geometry and drainage layout
  • Proposed attachment and conduit locations
  • Existing roof defects and maintenance access
  • The installer’s qualifications and contract responsibilities

Risks and trade-offs

  • Poorly coordinated installation can contribute to leaks, ponding, blocked access, or difficult maintenance.
  • Additional review may cost money and delay installation.
  • A solar installer may not be qualified to diagnose all roofing or drainage conditions.

Information you may need

  • Detailed roof and solar layout
  • Drainage, gutter, and downspout locations
  • Roof inspection and repair history
  • Written warranty and responsibility terms

What to do next

Ask for a drainage-specific revision and, if the issue remains unresolved, obtain an independent roof assessment before signing off on the design.
