The gauge of a metal roof refers to its thickness and the higher the gauge the thinner the metal. This combination of thickness and hardness is great for metal panels that require dent resistance. 29 gauge metal is used on 90 of homes with metal roofs. Many homeowners choose to install a 29 gauge roof with trim that is 26 gauge which can be more cost effective than a 22 gauge roof.

For example 26 gauge could be a steel as light as 0179 or as heavy as 0217. 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.

Benefits of higher gauges the biggest benefit of having a higher gauge roof is that it is less expensive. In most cases metal buildings are constructed with a steel gauge no higher than 28. The lower the gauge the thicker the metal. Each gauge represents a nominal decimal range.
