In the world of metal roofing, the gauge refers to the thickness of the steel. A lower number actually indicates a thicker, stronger panel. For example, 24-gauge steel is thicker and more durable than 29-gauge. Most residential standing seam roofs use 24 or 26-gauge to provide the best balance of strength and weight.
