John, have you noticed that roofing metal has gotten even thinner gauge?!
Alaskan suppliers oughtta be ashamed of the uber-thin sht they're selling
From my experience the typical panel from SBS, Northland wood, uresco and now the box stores has been 29 / 30 ga for awhile.
26 is usually a special order, although I think All Steel stocks 26ga coils nowdays.
Most people don't want to spend the extra money for the heavier gauge.
And, if its on plywood, it's ok.
If it's over purlins, you can sure tell when you're walking around on it!
