Is there or has there ever been a 12 year shingle. I live in a 12 year old community that a homeowner was to his installed shingles are a 12 year shingle. That were told the roofer got a code of the shingle to discover this. Was he fed a bunch of balony?
If not, what lifespan asphalt shingles were available in year 1991-2002. Thank you
