Metal Roof Gauge Recommendations

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.

Metal roof gauge recommendations.

A 22 gauge or 22ga metal roof might be nearly double the thickness of a 29 gauge 29ga metal roof. What is a roof gauge. Metal roof systems are composed of metal panels which are typically fabricated from 22 or 24 gage galvanized metal or aluminum and batten fill insulation. For example a 24 gauge copper roof panel is a different thickness than a 24 gauge steel roof panel.

It s not the easiest thing to understand. Gauge is the thickness of the metal used for a 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. These recommendations are with paint.

Selecting applying metal roofing touch up paint. The gauge of a metal roof refers to its thickness and the higher the gauge the thinner the metal. Exposed fastener corrugated steel roofing. Selecting metal roofing trim.

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. How to prepare for metal roof installation. Metal roofing thickness recommendations that include paint. To make matters all the more confusing different metals use different measuring standards.

Successful metal roofing systems require proper attachment procedures provisions for expansion and contraction and expedient removal of water snow and ice from the roof surface.
