The manufacturer states 25-30 years for shingles, but it's rarely the case they actually last that long unless you're paying for premium shingles. I'm in Canada though, so perhaps the harsher weather has something to do with that. Regardless, in Canada at least, 25-30 years for shingles is not common; 15-20 is more realistic from what I can tell in my area.

People who are talking about failures after 10-20 years are buying cut rate product and having it installed shabbily. https://www.gaf.com/en-us/document-library/documents/productdocuments/residentialroofingdocuments/atticventilationproductsdocuments/exhaustventsdocuments/cobraexhaustventforroofridgedocuments/Golden_Pledge_Limited_Warranty2018.pdf https://www.gaf.com/en-us/document-library/documents/product...
- deelowe 7y agoShingles are warrantied according to their rated life time. If you buy a 25yr shingle, it'll either last 25 years or you'll get free replacements.
