Guarantees & compliance

Can later solar-panel work affect a roof guarantee?

Short answer: It may if another contractor alters coverings, penetrations or waterproofing. Check the written terms and coordinate approval before installation.

What this means in practice

A useful handover proves what was installed, who is responsible and how compliance was achieved. Product warranties, workmanship guarantees, insurance-backed cover and Building Regulations certificates are different documents and should not be presented as interchangeable.

What to check next

  • Notify the guarantee provider first
  • Photograph mounting details
  • Separate roof and solar responsibilities in writing

When should you ask a roofer to inspect it?

Confirm the compliance and guarantee route before work starts, not after the scaffold comes down. At completion, check the property address, scope, dates, exclusions, transfer rules and issuing organisation, then retain the documents with the invoice and photographs.

Safety first: do not climb onto a roof without suitable access, training and protection. Keep clear of loose coverings, unstable ceilings and water near electrical fittings.
