Roofing manufacturers have changed their shingle warranties in a way that would give you the impression that the products are “more” or “better.”
My first experience with a shingle warranty was in the role of a consumer. That was in 1978 soon after the lovely Kay had accepted my proposal of marriage. I also proposed to build her a nice little house if she would allow me to use the engagement-ring money for a down payment. Promised to buy the ring on our fifth anniversary.
At the time, the basic strip shingle being installed on most new homes in our area was a 15-year, 240# per square three-tab (organic) asphalt shingle. A second choice was available for a few dollars more: the new 20 year, 225# per square three-tab fiberglass shingles manufactured by Johns-Manville.
