Path-Q Solar

Which roof conditions commonly add unexpected solar installation costs?

Answer

Common drivers include an aging or fragile roof, difficult access, complex geometry, structural reinforcement, unusual roofing materials, obstructions, steep slopes, and required roof replacement.

Key points

  • Solar should not be installed over a roof likely to need near-term replacement.
  • Structural and access conditions should be assessed before contract signing.
  • Electrical equipment may also create site costs.

What it depends on

  • Roof age and material
  • Structure and access
  • Panel layout and local requirements

Risks and trade-offs

  • Deferring roof work can require later removal and reinstallation.
  • Allowances may not cover concealed conditions.

Information you may need

  • Roof inspection
  • Structural information
