Detailed Answer
Warranty transferability is a common question when buying or selling a home with a newer roof. The details depend on the manufacturer and contractor.

- GAF: Transferable once within 60 days of sale. Non-prorated period may be reduced. Transfer fee: $0-$100 depending on warranty tier.
- CertainTeed: Transferable once within 60 days. Coverage continues at reduced level. Transfer form required.
- Owens Corning: Transferable once. Must notify within 60 days. Original warranty terms may be modified.
- IKO: Transferable once. 60-day notification required. Fee varies.
Key transfer rules
Timing is critical
Miss the 30-60 day transfer window and the warranty is void for the new owner.
One transfer only
Most warranties can only be transferred once. If the home sells again, the warranty does not follow.
Coverage reduction
A "limited lifetime" warranty often becomes 25 years upon transfer. Non-prorated coverage periods may shorten.
Documentation required
You need the original warranty registration, proof of installation, and a completed transfer form.
Contractor workmanship warranty transfers
This varies entirely by contractor. Some transfer automatically with the home, others are non-transferable, and some charge a fee. Ask your contractor at installation time about their transfer policy and get it in writing.
For home sellers
- Gather all warranty documents and installation receipts
- Include warranty details in your home listing — a transferable warranty adds value
- Initiate the transfer process during escrow to ensure timely filing
For home buyers
- Ask for roof warranty documents during due diligence
- Verify the warranty is still active with the manufacturer
- File the transfer paperwork within the required window
- Get a roof inspection before closing to document current condition
