How do I find my roof warranty information?

The four places to look

1. The installing contractor. The roofer who installed the roof keeps the project file with the shingle SKU, install date, square count, and warranty registration. Call the contractor with the homeowner's name and property address. Most reputable roofers maintain records for at least 10 years.

2. The shingle manufacturer's database. Major manufacturers (GAF, Owens Corning, CertainTeed, Malarkey, Atlas, Tamko) maintain warranty registration databases searchable by property address. Manufacturer customer service can confirm:

• Whether a warranty was registered for the address.
• The shingle product line and color.
• The install date and warranty term.
• The remaining transferable coverage if the home has changed hands.

Manufacturer contact information:

• GAF: gaf.com/en-us/about-us/contact-us
• Owens Corning: owenscorning.com/en-us/roofing/contact-us
• CertainTeed: certainteed.com/contact-us
• Malarkey: malarkeyroofing.com/warranty-information

3. The home closing file. The closing documents from the home purchase typically include the seller's disclosure statement, prior inspection reports, and any warranty paperwork the seller passed to the buyer. Check the closing binder from the title company or the homeowner's personal records.

4. The home-inspection report. Home-inspection reports from a recent purchase often note the roof's age, material, and any visible warranty stickers or installer placards on attic rafters or in the electrical panel area. The report does not constitute warranty proof, but the documented install date narrows the search.

What to do when no record exists

When the contractor is out of business, the manufacturer has no registration, and the closing file is silent, the warranty is effectively unrecoverable. Practical next steps:

• Verify the shingle product line through a physical inspection (the manufacturer name and SKU are typically printed on the back of each shingle and on the bundle wrappers if any remain in the attic).
• Estimate the install date from visual condition, prior aerial imagery (Google Street View historical), and any seller-provided records.
• Treat the roof as having product-warranty coverage only at the manufacturer's standard non-registered tier, which is shorter and less comprehensive than the registered version.

How to preserve future warranty access

For a new install, ask the contractor to:

• File the manufacturer warranty registration within the deadline (typically 30 days to 1 year).
• Provide a copy of the registration confirmation in writing.
• Note the warranty terms in the written contract (manufacturer name, product line, term, transferability).

Store the documents in the home file. If the home sells, transfer the documents to the new owner per the warranty's transfer rules.
