What warranty risks arise if the installer uses subcontractors for roof or electrical work?

Answer

Subcontracting is not automatically a warranty problem, but it can make responsibility unclear when a roof leak, wiring fault, or system failure involves more than one contractor. The contract should make the primary installer responsible for coordinating subcontractors and resolving workmanship claims.

Key points

  • Confirm who is responsible for roof penetrations, flashing, structural attachment, electrical work, inspections, and resulting damage.
  • Require the installer to identify subcontracted scopes and remain your single point of contact for warranty claims.
  • Check whether subcontractors provide separate workmanship warranties and whether those warranties can be transferred to you.
  • Verify that warranty coverage does not depend on using a particular subcontractor or on submitting separate claims to multiple parties.

What it depends on

  • The contract's allocation of responsibility
  • The scope and duration of workmanship warranties
  • Whether subcontractor warranties are assigned to the property owner
  • The installer’s claim-handling and escalation obligations

Risks and trade-offs

  • Separate warranties can create delays, disputes, or gaps when the cause of damage is uncertain.
  • A roof contractor may deny responsibility for solar attachments, while the solar installer may deny responsibility for the roof membrane.
  • A lower-price proposal may provide less coordinated post-installation support.

Information you may need

  • The proposed contract and all warranty documents
  • The identity and role of each subcontractor
  • Who pays for diagnosis, removal, reinstallation, and consequential repairs
  • Evidence of applicable insurance and licensing

Your next step

What to do next

Ask the installer to provide a written responsibility matrix and revise the contract so the primary installer coordinates and backs all subcontracted work.
