Path-Q Solar

What evidence should I check before choosing an installer for a complex roof?

Answer

Check evidence of completed work on roofs with similar materials, slopes, penetrations, shading, structural constraints, and access conditions. Also verify references, licensing or qualification requirements where applicable, insurance, engineering or structural capabilities, and the installer’s documented approach to waterproofing and repairs.

Key points

  • Ask for recent, comparable project references rather than only general testimonials.
  • Review drawings or photographs showing attachment, flashing, setbacks, and equipment placement.
  • Confirm who performs structural review, roofing work, electrical work, and inspections.
  • Look for clear change-order and damage-resolution procedures.

What it depends on

  • Roof material, age, slope, and geometry
  • Structural and access conditions
  • Installer's relevant experience and subcontracting model
  • Scope of roofing and electrical work

Risks and trade-offs

  • Complex roofs increase leak, access, repair, and change-order risk.
  • A specialist may cost more but reduce installation and service risk.
  • References may not reveal unresolved disputes unless questions are specific.

Information you may need

  • Comparable project references
  • Installer qualifications, insurance, and subcontractor roles
  • Proposed attachment and waterproofing method
  • Workmanship, damage, and change-order terms

Your next step

Ask shortlisted installers for two or more comparable references and a written site-specific installation plan, then contact the references with targeted questions.
