Metal Gauge For A Roof

Manufacturers in the united states use gauge to express the thickness of metal roof panels.

Metal gauge for a roof.

22 gauge is the thickest while 29 gauge is the thinnest. Gauge is the thickness of the metal used for a roof. For example 26 gauge could be a steel as light as 0179 or as heavy as 0217. Each gauge represents a nominal decimal range.

The problem with metal roofing gauge is that there is a wide range of tolerances. That means a 22 gauge or 22ga metal roof could be close to double the thickness of a 29 gauge 29ga metal roof. Each number represents a range of inches 0 0179 to 0 0217 for example so two roofs may have the same gauge but slightly different thicknesses. A 22 gauge or 22ga metal roof might be nearly double the thickness of a 29 gauge 29ga metal roof.

For example a 24 gauge copper roof panel is a different thickness than a 24 gauge steel roof panel. These numbers refer to the decimal thickness of the steel and they have a range. It s a little confusing and it gets worse because different metals also use different measuring standards. The most common gauges for metal roofing are 29 26 24 and 22 gauge.

Any difference is minimal in actual thickness but may have an effect on how sturdy the metal is. While a beautiful new home with a standing seam roof would likely be 24 gauge. Most metal roof and metal siding panels on the market are between 20 29 gauge with 20 gauge being the thickest and 29 gauge being the thinnest panels sold. Low end agricultural jobs are normally 26 gauge or 29 gauge.

Metal roof panels are measured by gauge and are usually between 22 and 29. To make matters all the more confusing different metals use different measuring standards. For example one company might sell a product as being 24 gauge but in reality the thickness of the metal could vary from 0 018 to 0 0335 based upon exactly how that company looks at things and how big of a tolerance they allow for. It s important for you as a homeowner to know about the gauge thickness of a metal roof so you can select the best one for yourself.

The vast majority of what we sell is either 26 gauge metal roofing or 24 gauge metal roofing. For example a 24 gauge copper roof panel isn t the same thickness as a 24 gauge steel roof panel.
