24 gauge metal roofing is 0.0179 inches thick, which is about the thickness of a dime. This measurement comes from the gauge system used for sheet metal. Lower gauge numbers mean thicker metal, so 24 gauge is thinner than 22 gauge or 20 gauge. Most residential metal roofs use 24 gauge or thicker material to last a long time.
What Does 24 Gauge Mean?
Gauge is a number that tells you how thick metal is. The gauge system works backwards from what you might think. A higher gauge number means thinner metal. A lower gauge number means thicker metal.
24 gauge metal is 0.0179 inches thick. You can compare it to common items: a standard sheet of paper is 0.004 inches thick, and a dime is 0.053 inches thick. So 24 gauge sits between those sizes.
