Architectural warranty

ok guys, this may be a stupid question, but when a customer ask how long is the manufactures warranty with the “30” year shingle you plan to install. I always say that no shingle offers a 30 year warranty. Most are usaly 10-15 years. Am I wrong? Is their a brand that actally offers a 30 year warranty?

Feedback would be helpful. I know its a dumb question, but I want to get to the bottom of it.

Its not a dumb question if you dont know the answer. Ct it is a 30 year pro rated warranty. Like Certainteed give a 5 year sure start warranty anything goes wrong they cover it materials and labor, after that they just cover materials and they cover less each year from that day forward.
