To make matters all the more confusing different metals use different measuring standards.
Standard metal roof thickness.
22 gauge is the thickest while 29 gauge is the thinnest.
A 22 gauge or 22ga metal roof might be nearly double the thickness of a 29 gauge 29ga metal roof.
Minimum 0145 aluminum shingles.
For example a 26 gauge steel panel can range between 0 0179 and 0 0217 inches thick according to a university.

When installed however the shingles overlap doubling the thickness.
Kynar galvalume steel for metal roofing and gutters.
Standard asphalt shingles add very little thickness to the roof because a standard three tab shingle is about 3 16 inch thick.
The gauge of a metal roof refers to its thickness and the higher the gauge the thinner the metal.
For example a 24 gauge copper roof panel is a different thickness than a 24 gauge steel roof panel.
Minimum 024 aluminum standing seam.
However standing seam panels are typically somewhere between 22 and 26 gauge with the most common galvalume steel thickness being 24 gauge and aluminum between 032 and 040 inches.

Manufacturers express the thickness of metal panels as their gauge with 22 gauge being the thickest and 29 gauge the thinnest of traditionally sold metal roof and wall panels.
For example standard 29 gauge steel roofing made in long panels is about 0 36 millimeters thick and the 26 gauge version is slightly thicker at 0 48 millimeters.
Minimum 024 steel standing seam.
