What year did 3-tabs jump from a 20yr. warranty to a 25/30?

I know this question is old but I can’t find anything about 20 year shingles being discontinued. Have you found out the answer to this question? I still have an insurance trying to put 20 yr comp shingles and won’t budge when i ask them to change it to 25 year comp shingles. Thanks

They are not totally discontinued. Just unavailable in most markets. If they are discontinued, it is recent.

Oh ok that explains why some insurance adjusters are still putting 20 year shingles then. Thank you so much for your answers!
