Path-Q Solar

What should a solar quote say about responsibility for preexisting roof leaks?

Answer

The quote should document known roof conditions and clearly distinguish preexisting leaks from leaks or damage caused or worsened by the installation. It should state who investigates each condition, who pays for preexisting repairs, what workmanship coverage applies to installation-caused leaks, and how disputes will be documented.

Key points

  • Use dated photographs, inspection findings, and a written roof-condition record before work starts.
  • Define whether installation over a known defect changes the installer’s responsibility.
  • Specify repair methods, response times, access, and any panel removal or reinstallation costs.
  • Avoid relying on a general disclaimer that does not distinguish cause.

What it depends on

  • The roof's documented condition before installation
  • The attachment, flashing, and waterproofing method
  • The warranty and property-damage provisions in the contract

Risks and trade-offs

  • A broad preexisting-condition exclusion can leave the homeowner responsible for difficult leak investigations.
  • Failing to repair a known issue before installation can increase later removal and repair costs.
  • A clear baseline inspection may add upfront effort but reduce causation disputes.

Information you may need

  • A preinstallation roof inspection and photographic record
  • The quote's leak, damage, repair, and exclusion language
  • The process for determining causation and paying for emergency work
