I have 42 yrs. experience in the business in Cen. Fla. Unless damaged by hail or some other severe weather, 3-tab shingles are considered to be a 25 yr. product and architecturals, 30 yrs. Shingle mfrs. warranty that - on a prorated basis, in their written warranties. Why would they do that if their products won't actually last that long? Some granule loss is not an indicator of impending failure. I have been on - or actually worked on, in excess of 10,000 roofs. You need an inspection report from an honest roofing company.
