Roof Warranty Transfer: What Sellers and Buyers in Boise Need to Know

Two warranties, two different sets of rules

A roof replacement typically comes with two separate warranties, and homeowners selling or buying a house often assume they are the same thing. They are not, and mixing them up is the most common warranty mistake in a home sale.

Manufacturer material warranty. Covers defects in the shingles, underlayment, or metal panels themselves, backed by the company that made the product, not the installer. These typically run for decades, sometimes the lifetime of the original owner, and often step down to a shorter, prorated, non-lifetime term once the home changes hands, even after a transfer.

Workmanship warranty. Covers installation mistakes, like improperly sealed flashing, poor ventilation, or nail patterns that void the material warranty on their own. This is issued by the roofing contractor, not the manufacturer, and typically runs a much shorter term, commonly two to ten years depending on the company.

A roof can have a fully intact material warranty and an expired workmanship warranty, or the reverse, so check both separately rather than assuming one document covers everything.

What actually happens at closing

Step	What to do
Before listing	Pull the original roofing contract and invoice; note the contractor, material, and install date
Before listing	Contact the manufacturer to confirm current material warranty status and transfer requirements
Before listing	Contact the original contractor to confirm workmanship warranty status and whether it transfers at all
During escrow	Provide both warranty documents, or confirmation of terms, to the buyer as part of disclosures
After closing	The new owner (or their agent) completes any required manufacturer transfer registration within the stated window

Missing the manufacturer’s transfer window is the most common way a buyer loses coverage that was otherwise still valid. Some manufacturers require the paperwork filed within 30 to 90 days of the closing date, and coverage lapses permanently if that window passes, even if the roof itself is only a few years old.

What sellers should do before listing

If your roof was replaced within the last several years, gather the paperwork before you list rather than scrambling for it during a home inspection negotiation. A buyer’s agent will ask, and having documented, transferable warranty coverage is a genuine selling point that supports your asking price, especially in a Treasure Valley market where a large share of homes are aging into their 20 to 30 year replacement window and buyers are increasingly roof-conscious.

If you cannot locate the original paperwork, the manufacturer can often look up registered warranties by address or by contacting the original installing contractor, if they are still in business. A roof replaced without a formally registered warranty may still have implied manufacturer coverage on defective material, but a workmanship warranty generally requires the original paperwork to enforce.

What buyers should do before or right after closing

Do not assume a roof mentioned as “newer” in a listing carries transferable coverage. Ask for the specific documentation during your inspection period, not after closing when your negotiating leverage is gone. If the seller cannot produce it, you can still contact the manufacturer directly with the product line and an approximate install date, though without a registered warranty on file the manufacturer may not be able to confirm coverage either way.

If you are buying a home with a roof nearing the end of its expected lifespan, factor the cost of a future replacement into your offer rather than relying on warranty coverage that may not exist or may not transfer.

Bottom line

Manufacturer and workmanship warranties are separate documents with separate transfer rules, and neither should be assumed valid without paperwork in hand. Sellers benefit from confirming and documenting both before listing; buyers benefit from asking for that documentation during the inspection period, not after closing.
