Roof Warranty Terms: Material Coverage Is Not the Same as Workmanship

A roof warranty can contain different terms for manufacturing defects, wind, algae, and workmanship. Compare the exact document and installation requirements, not only the largest year printed in the proposal.

A roof warranty can contain different terms for manufacturing defects, wind, algae, and workmanship. Compare the exact document and installation requirements, not only the largest year printed in the proposal.

Keep the coverage categories separate

GAF's Shingle and Accessory Limited Warranty separates manufacturing-defect, wind, and algae provisions and identifies limits and conditions. The document is an example of why one headline term does not describe all coverage.

A contractor's workmanship agreement is a separate item unless the specified manufacturer package expressly includes relevant installation coverage. Ask who handles the claim and what labor, removal, disposal, accessories, or other costs are included.

What should be retained?

  • The warranty applicable to the installation date and exact products.
  • The invoice, product information, and completion date.
  • Any required registration or confirmation.
  • The contractor's workmanship agreement.
  • Repair and maintenance records.

If ownership changes, check the applicable transfer instructions promptly. Do not assume a warranty follows the property unchanged.

For example, a long manufacturing-defect term cannot be used to promise payment for any future leak. The cause, terms, and remedy need evaluation. Read the actual document with the installer and ask the issuer to clarify any uncertainty.
