Path-Q Solar

How can I tell whether a solar installer has experience with complex roofs?

Answer

Ask for specific examples of roofs with similar slopes, materials, age, obstructions, structural conditions, and access challenges, and verify those examples through references and project documentation.

Key points

  • Ask how the installer evaluates roof structure, remaining roof life, flashing, drainage, access, and fire or maintenance pathways.
  • Request photos or references for comparable projects rather than relying on a general claim of experience.
  • Ask who performs the structural and waterproofing design and who is responsible if hidden conditions are found.
  • Confirm that the proposal includes any required roof repairs, structural work, equipment relocation, or access provisions.

What it depends on

  • Roof type, pitch, age, and condition
  • Roof penetrations and attachment method
  • Shading, dormers, skylights, chimneys, and other obstructions
  • Structural capacity and access for installation and future maintenance

Risks and trade-offs

  • A roof that appears suitable may require repairs or reinforcement after inspection.
  • Complex layouts can increase labor, maintenance difficulty, leak risk, and cost.
  • A portfolio of simple installations does not establish competence with the specific roof conditions involved.

Information you may need

  • Roof age, material, pitch, drawings, and known defects
  • Photos or inspection findings showing obstructions and access constraints
  • Comparable project references and the proposed attachment and waterproofing approach
  • Names and roles of any structural consultant or subcontractor

Your next step

What to do next

Give each candidate the same roof information and ask for two comparable project references plus a written explanation of the proposed mounting, waterproofing, and contingency approach.
