Path-Q Solar
Should I get a structural inspection before or after requesting solar quotes?
Answer
Usually, request preliminary quotes first and disclose any structural uncertainty, then obtain a structural inspection before accepting a final design or contract when the roof is older, unusual, damaged, heavily loaded, or otherwise uncertain. An installer may identify whether an inspection is needed.
Key points
- An initial quote can establish system options and reveal whether structural review is likely to affect the design.
- A structural professional should assess the building and roof framing where the condition or load capacity is not adequately documented.
- The final design should account for panel, racking, wind, snow, and other applicable loads.
What it depends on
- Age, construction, condition, and documentation of the roof and structure
- Existing roof-mounted equipment and the proposed array size
- Installer findings and applicable structural requirements
Risks and trade-offs
- Inspecting too early can add cost before knowing whether solar is viable; inspecting too late can delay or change the project.
- A quote conditioned on structural approval is not the same as confirmed structural suitability.
- Roof repairs or reinforcement may be more economical before panels are installed.
Information you may need
- Roof age, framing information, repair history, and existing loads
- Preliminary array layout and equipment weights
- Installer's structural review process and any inspection contingency
