Path-Q Solar

How can I decide whether a second roof inspection is justified when installers disagree about suitability?

Answer

A second inspection is justified when the disagreement could change the decision, such as whether the roof needs replacement, can support the proposed installation, or carries significant leak or structural risk. Use an independent, suitably qualified assessor when the installers have conflicting evidence rather than simply choosing the more optimistic opinion.

Key points

  • Ask each installer to state the specific basis for its conclusion and what evidence would resolve the disagreement.
  • Separate structural suitability, roof age and condition, waterproofing, and solar layout questions.
  • An independent inspection is more valuable when repair or replacement costs are large or difficult to reverse.
  • Request a written report with photographs, limitations, and recommended corrective work.

What it depends on

  • The nature and severity of the disagreement
  • Roof age, construction, condition, and warranty
  • The cost of inspection compared with potential repair or removal costs
  • Whether the proposed system depends on disputed assumptions

Risks and trade-offs

  • The inspection adds cost and may delay the project.
  • Proceeding without resolving a material conflict can cause leaks, removal costs, or shortened system life.
  • An inspection does not eliminate uncertainty if concealed conditions are not observable.

Information you may need

  • Both installers' written assessments
  • Roof records, prior repairs, and warranty information
  • Photos or measurements supporting each conclusion
  • The proposed solar attachment and loading assumptions

Your next step

What to do next

Obtain the conflicting reports, identify the decision they would change, and hire an independent roof or structural professional if the unresolved issue is material.
