Four are epdm membranes and the fifth is a polyurathane liquid. Each gauge represents a nominal decimal range. The gauge of a metal roof refers to its thickness and the higher the gauge the thinner the metal. 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.

The thicknesses are listed below. Tpo is a type of roofing membrane that can come in a variety of thicknesses. Please understand that recommended metal thicknesses will vary based on the design and engineering of the metal product being considered that said here are a few general recommendations. The most common thickness is probably 60 mils.

Porch roof extensions for hip roof porch extensions from an existing building wall you can use half the calculator results. A mil is a unit of measure where 1 mil is equal to 0 001 inches. 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.
